Description
Technical field
The invention belongs to Winter Wheat Root maize ear rot Prevention Technique field, relate to a kind of prevention Winter Wheat RootThe method of maize ear rot.
Background technology
Root rotof flax Chinese another name: spot disease, black embryo disease, bacterial wilt, Latin formal name used at school:DrechsleraSorokiniana (Sacc.) Subram.Gain, root rotof flax is mainly by yellowThe fungies such as sickle spore, fusarium oxysporum, Fusorium moniliforme Sheldon, Gerlachia nivalis, chain lattice spore, botrytisCausing, is the disease of multiple bacterium Combined Infection. The reason of root rotof flax aggravation in recent years:
1. illumination deficiency, soil stickiness are large, and the water yield is large, stuffy, and root damaged etc. is allThe main cause that causes germ to invade.
2. planting patterns is single, Wheat Maize-wheat, and continuous cropping causes pathogenic bacteria in soil year after yearA large amount of accumulation.
Symptom: infection process root, first forms brown at bud scale, spire, root cap and subterranean stem placeLook, to black scab, expands gradually and makes it rotten, and morbidity back root part is gradually become by light brownDark brown, concentrates dead after wheat flowering. Generally, germ is wheat, barley, blackIn the invalid body of wheat, oat and multiple grassy weed and soil, survive the winter, become wheat root in next yearThe primary source of infection of maize ear rot. In Wheat Production there is profound change in the cropping system of nearly more than ten years:Return crop stocks to the field for a long time and cause the remaining germ of soil to increase year by year, do not plough deeply for many years arable land, only with shallowRake loosens the soil, and causes soil cultivating layer to shoal (in general 15 centimetres), and topsoil is soft, ploughBottom is hard, is unfavorable for that crop root pricks (wheat root can reach underground 3 meters the most deeply) deeply, makesBecome root rotof flax severe generation year after year throughout the country, form incurable disease at Wheat During Later Period of Growth,The general 5%-15% of underproduction rate, seriously can reach more than 30%.
In current data, relevant root rotof flax is prevented and treated the shortcoming of method and is: cultural control method is oldOld, not easy to operate; Chemical prevention and control method weak effect, medicament are out-of-date; Do not form a cover systemScheme, just propose to prevent and treat suggestion from certain aspect, in agricultural production, do not form sampleThe double method that solves root rotof flax of controlling. Cause root rotof flax in recent years to spread expansion in various placesThe situation of the safety of serious threat Wheat Production greatly.
Existingly prevent and treat method one, take to plant disease-resistant variety and cultivation diseases prevention is main, be aided with medicineThe aggregate measures of agent control. 1. breeding resistant variety. 2. strengthen cultivation prophylactic measures. Control seedlingThe key of phase disease is to begin sowing in good time, and uses sufficient base manure, topdresses in time, and earthing should not be excessively dark, wheatNot continuous cropping of field. 3. dressing seed. With 25% triadimefon or 50% thiram or 50% iprodioneWettable powder seed dressing, consumption is seed weight 0.2%. 4. chemical control. Grave illness year andTime spray medicine protection, for the first time at jan flowering wheat, at the wheat milking maturity initial stage, medicament has for the second time25% triazolone and 50% thiram wettable powder.
Existing control method two, 1. maintain strict control over seed pass. The annual required wheat seeds of wheat of planting must be from farPlace is called in without lesion. 2. chemical control. Before sowing, seed is wanted with medicament seed dressing, and method is with planting20% triadimefon missible oil (triazolone) of son amount 0.3% or 0.3% 50% Tuzet wettable powderAgent or 0.15% 80% Zineb wettable powder seed dressing, before liriope minor tri-leaf period or survive the winter afterTurn green to the phase of standing up be water the first water the spring before, 20% triadimefon missible oil 100 is sprayed on every mu of blade faceGram. 3. cultural control. When sowing, soil must be flattened, whole thin, broadcast first every mu and execute fully200 kilograms of the above or biological organic fertilizers of 2 cubic metres of the fertilizers that become thoroughly decomposed, and enrich potassium sulfateMore than 10 kilograms, the sowing time rested in before and after October 1,3～4 centimetres of depths of plantingLeft and right. After harvesting wheat, Mai Gen and invalid body fully be cleared out of to wheatland and burn, for useAbove-mentioned measure still uncontrollable sick field should be in time and the non-gramineous crop such as pulse family, CruciferaeCarry out above crop rotation in 2 years.
The shortcoming of prior art is 1, weak effect, aborning can only be to general soil such as banded sclerotial blightsBiography disease is effective, substantially invalid to root rotof flax; 2, not easy to operate, actual de-with productionJoint, does not have actual production meaning.
Summary of the invention
The object of the present invention is to provide a kind of method of preventing Winter Wheat Root maize ear rot, solved existingThe method of some prevention Winter Wheat Root maize ear rots is not easy to operate, the problem of weak effect.
The technical solution adopted in the present invention is to carry out according to following steps:
Step 1: straw decomposing inoculant is mixed to fine earth and spread fertilizer over the fields to remaining stalk after autumn harvest cornUpper, wait for that stalk becomes thoroughly decomposed completely;
Step 2: mix fine earth or fertilizer evenly spreads fertilizer over the fields field before wheat ground with soil conditionerEarth's surface, rotary tillage soil-working;

Below in conjunction with detailed description of the invention, the present invention is described in detail.
The control policy of root rotof flax is to put prevention first, integrated control. Once find dead strain,The symptom such as rotten, has pasted medical help, and so-called " seven points of kinds, three are in charge of ", this method is passed throughSix environment that step is created to be unfavorable for that disease occurs from multiple angles, are controlled at rudiment by diseaseIn. Prevention method is:
One, straw decomposing inoculant Treating straw:
1, principle: government actively promotes straw-returning technology, has increased the soil organism, has fostered and apply fertilizerSoil fertility, the stalk that has little time in a large number to become thoroughly decomposed naturally generates heat simultaneously in soil, consumes certain nitrogenFertilizer, and burn out wheat root; Fluffy stalk also easily makes the freezing wheat root of cold current in severe winter,These wounds can bring out infection process wheat plant. Straw decomposing inoculant is as a kind of microbial bacteriaAgent can be decomposed corruption stalk fast, invalid organizing after decomposition, and germ just can not survive in soil,Avoid the generation of the problems referred to above.
2, method: harvest corn in the fall, timely with 1000 grams/acre of straw decomposings after crushed stalkAgent is mixed fine earth and is spread fertilizer over the fields on stalk, after two weeks, becomes thoroughly decomposed completely.
Two, the conditioning of soil:
1, principle: along with the change of cropping system, plough deeply unrealistic, soil compaction,Gas permeability reduces, arable layer shoals, plough sole is hard, and all unfavorable wheat root is pricked deeply, causesThe weak seedling of wheat, sick seedling increase, and soil-borne disease insect pest seriously occurs. The present invention adopts a kind of soil to adjustReason agent, taking water as carrier, by physical action, utilizes the positive and negative charge active force producing, fromProgressively improvement and the crumb structure of rehabilitating soil on microcosmic, break soil compaction, and then conditioned soilThe permeability of earth, promotes wheat root prosperity and anti-adversity ability, improve simultaneously the soil water, fertilizer,Gas, hot supply condition, conditioning soil acid-base equilibrium, promote the useful mushroom breeding of happiness oxygen, presses downAnaerobic bacteria processed, fungi (comprising multiple sac fungus, the sporangiocyst bacterium that causes root rotof flax).Be formed with the soil environment that is beneficial to wheat healthy growth;
2, method: every mu of use 25% is exempted from 1000 grams/acre of cultivated (An Gerui) soil conditioners in Shen and mixed thinSoil or fertilizer evenly spread fertilizer over the fields earth's surface, field before wheat ground, then behind the whole ground of Rotary tillage rake, prepare to broadcastKind.
Three, wheat seed dressing dressing:
1, principle: Root Rot of Wheat germ survives the winter inside and outside seed He in invalid body, due to continuous cropping soilContent of molds is large, causes the residual accumulation year by year of germ. After wheat cultivation, the disease in seed or soilBacterium is invaded from young shoot sheath, then spreads up and down to positions such as spire sheath and root caps. Wheat seed dressing bagClothing use exactly bactericide, pesticide, nutritional agents in wheat seed outside to Seed Development protective layer,Nutritive layer, builds a good subenvironment, and protection Wheat Seedling is grown safely.
2, method: with 3% difenoconazole suspending seed-dressing agent 100 grams+0.01% rape element Inner ester 4Gram 0.5 kilogram, water is mixed to 15 kilograms of wheat seeds, after mixing thoroughly, dry standby broadcasting in shady spot.
Four, sowing time and during Wintering Period are strengthened cultivation management:
1, principle: winter wheat sowing is more late, sowing is dark, causes seedling to emerge slowly, has extended and has invadedDye the time, infect advantage is provided for pathogenic bacteria, consume a large amount of nutrition simultaneously, make the growth of cereal crop seedlingsDie down, especially the cold spell in later spring of three to April makes wheat seeding be subject to freeze injury, can bring out root rotOccur; Sowing can cause too early wheat seedling growth excessively prosperous, sowed shallow, the easy frostbite root of surviving the winter,Germ is easily invaded; Premunition that soil moisture is too low or too high, rich water is not enough declines, nitrogenous fertilizer mistakeAmount etc. all makes this disease increase the weight of.
2, method:
One, the rational application of fertilizer, uses sufficient base fertilizer, appropriate Potassium, zinc fertilizer, boron fertilizer, calcareous fertilisers etc.;
Two, sufficient moisture in the soil is sowed, and one broadcasts full stand, and early sowing in good time, upper seeding, avoid, overdrying excessively wet at soilUnder condition, sow, control depth of planting, precision drilling, improves seeding quality, the control of the wheat seeds amount of broadcastingBuilt in 18～20,000 grams/acre;
Three, winter irrigation in good time, cultivates and survives the winter strong sprout. In locality, the lowest temperature at night drops to subzero 1-2 °When C, start that wheat is entered to winter irrigation and irrigate, can keep ground temperature, cultivate strong sprout, promote to tiller.
Five, period of seedling establishment management:
1, principle: after year, early March is along with temperature gos up, and pine root fungus is breaking dormancy also, by invadingThe stage of dying transfers the stage of spreading to, and now wheat plant is shorter simultaneously, is conducive to prevent and treat wheat rootRoot rot germ. Be while effectively preventing last key of root rotof flax this periodPhase.
2, method: the wheat last ten-days period in February to the first ten-day period of the March Tebuconazole, triazolone, first frost for period of seedling establishmentSpirit, dislike 1000 times of liquid of the bactericide such as mould spirit and aim at the spraying of wheat plant roots, use liquid for every mu50 kilograms, can effectively kill the soil-borne disease bacterium such as Root Rot of Wheat germ.
Six, wheat grain filling period management:
1, principle: be the most vigorous period of wheat reproductive nutrition and growing nutrient this period, nutrientReach the peak value of whole breeding time with the demand of moisture, infect the diseased plant of root rotof flax due to suctionThe ability of receiving, conducting nutrient and moisture declines, May scorching sun simultaneously, the evils such as hot dry windBad condition is easy to cause root-rot diseased plant acute death. Suitably supplement foliage fertilizer and can alleviate root rotThe absorption of strain root, conducting pressure, directly supply nutrient by blade face; Spray plant growth regulatesAgent can stimulating plant potential, strengthens resistance against disadvantage. For example: spray continuously rape at Wheat in Grain Filling StageElement Inner ester can be resisted hot dry wind 2 times, makes plant straw staygreen, improves output.
2, method: at 100 grams/acre of 92% potassium dihydrogen phosphate crystals or humic acid solution for Wheat in Grain Filling StageFertile 100 grams/acre add that 6 grams/acre of 0.01% rape element Inner esters are to 30 kilograms of wheat foliar sprays of water,Notice that spraying time is selected in medication after at 5 in afternoon, in order to avoid produce fertilizer damage, interval sprays one in one week againInferior.
Advantage of the present invention is to start with from the pathogenic factor of root rotof flax, creates unfavorable disease and sends outRaw condition solves the harmfulness of root rotof flax; Method is easy, and orderliness is clear, in productionEasily operation; Prevention effect is good, nuisanceless to environment, has solved cropping system and has changed and to bringDeep-seated problems. And the present invention takes brand-new method to start with from many aspects for the first time, from rootIn basis, having solved the difficult problem of preventing and treating of root rotof flax, is to adapt to current Wheat Production cropping system,Effectively prevent and treat the method for root rotof flax, have simple and easy to do, practical reliable, treat both principal and secondary aspect of diseaseAdvantage, has solved and has changed a difficult problem that causes root rotof flax to spread because of cropping system.
