Abstract
The invention relates to a preparation method of a nutrient used for soilless culture of cucumbers by using sustained released gel as a carrier, belonging to the technical field of plant nutrients. The preparation method comprises the steps of taking gelatin solution, adding activated carbon, mixing uniformly, heating, keeping the temperature, adding acetone and glutaraldehyde, heating, keeping the temperature, reducing the temperature, and filtering to obtain a solid substance; stirring carbomer, polycarbophil, sodium alginate and water, then adding calcium nitrate tetrahydrate, potassium nitrate, diammonium hydrogen phosphate, magnesium sulfate heptahydrate, manganese sulfate, vitamin B group, chitosan, nicotinamide and amino acid, and mixing uniformly to obtain a mixture I; adding sodium hydroxide solution into the mixture I, then adding organic acid and the solid substance, mixing uniformly and standing to obtain the product. The sustained released type nutrient for soilless culture of cucumbers eliminates the disadvantage that nutrients are required to be added in cultured water frequently, can be added one time per mouth generally, and can improve the yield of the cucumbers produced by soilless culture.
Description
Technical field
The present invention relates to the preparation method of the nutrition agent that a kind of yellowish-white soilless culture uses, particularly relate to and using sustained-release gel as the preparation method of the cucumber soil-less culturing nutrient agent of carrier, belong to plant nutrient agent technical field.
Background technology
Soilless culture is exactly without soil, uses the technology of nutritional liquid grown plant completely, is a significant innovation in mankind's planting patterns.Soilless culture is not only grown soon, output is high, quality good, and the mankind's plantation activity has been liberated out from the constraint of soil, for realizing batch production, the automatization of agricultural, horticultural production, has opened wide prospect.
Soilless culture is without natural soil raise crop, and by arable farming in nutritive medium, this nutritive medium can replace natural soil to provide moisture, nutrient, oxygen, temperature to crop, makes the crop can normal growth and complete its whole life cycle.
Nutritive medium is the key of soilless culture, and Different Crop requires different nutrient solution prescriptions.The formula of delivering in the world is at present a lot, but similar, because initial formula originally comes from the chemical composition analysis to soil extraction.In nutrient solution prescription, difference maximum be the ratio of nitrogen and potassium wherein.
Cucumber, also claims cucumber, green cucumber, teaselgourd, belongs to cucurbitaceous plant.Cultivation history is long, is distributed widely in all over China, is worldwide vegetables, and is one of main greenhouse product.The melon skin of cucumber was dark green originally, had put for a long time and can gradually become yellow, was called again strong yellow melon.
Cucumber, when soilless culture, need to be controlled environment: temperature remains on 20～28 ℃ of left and right daytime, is the highlyest no more than 32 ℃, and night, temperature was not less than 10 ℃, will keep the day and night temperature of 10 ℃ to be beneficial to bud differentiation simultaneously.General fine weather atmospheric moisture remains on 80% left and right.
And it is more strict to the control of nutritive medium, generally need within every 2～3 days, add 1 time.Taking out the climing phase, after field planting, 3～5d need coordinate drip irrigation with manually watering nutritive medium, and every day at the upper and lower noon respectively waters 1 time, each 100～250mL/ strain.After 3～5d, use again drip irrigation pipe dropping liquid, every day 3 times, each 3～8min, individual plant service discharge is 0.5～1.5L, at most 2L.In flowering period, nutrient solution concentration should be brought up to 1.2～1.5 dosage.
Summary of the invention
The object of the invention is: a kind of cucumber soil-less culturing nutrient agent that slow-release material is carrier of take is provided, while reducing soilless culture, carries out too much the operation that applies of nutritive medium, reduce working strength.The technical scheme adopting is as follows:
A preparation method for slow release type cucumber soil-less culturing nutrient agent, comprises the steps:
The 1st step, by weight, get mass concentration and be 50～60 parts of 5%～10% gelatin solutions, add the gac of 5～8 parts, mix, then be warming up to 40～50 ℃, be incubated 1～2 hour, then add the acetone of 5～10 parts and the glutaraldehyde of 8～16 parts, be warming up to 45～55 ℃, be incubated 2～4 hours, be cooled to again 5～10 ℃, filter, obtain solids;
The 2nd step, by weight, get 20～30 parts of carbomers, 5～15 parts of Polycarbophils, 10～20 parts of sodium alginates, 50～80 parts, water, stir 4～6 hours, add again 5～10 parts of four water-calcium nitrates, 10～12 parts, saltpetre, 8～16 parts of Secondary ammonium phosphates, 5～10 parts of magnesium sulfate heptahydrates, 0.2～0.4 part of manganous sulfate, 0.05～0.1 part of vitamin B complex, 0.5～1 part of chitosan, 0.5～2 part of niacinamide, 0.5～2 part, amino acid, mix, obtain mixture I;
The 3rd step, in mixture I, add sodium hydroxide solution until pH is 6.0～7.0, then add the solids of 3～6 parts of organic acids and the 1st step gained, after mixing, standing 12～24 hours.
Preferred, described vitamin B complex is vitamin B6 or vitamin B12.
Preferred, described amino acid is a kind of in α-amino-isovaleric acid, methionine(Met) or Isoleucine.
Preferred, described organic acid is oxysuccinic acid or nicotinic acid.
Preferred, in the 3rd described step, the mass concentration of sodium hydroxide solution is 1%～3%.
beneficial effect
Slow release type cucumber soil-less culturing nutrient provided by the invention agent, has exempted the deficiency that needs frequently to add nutrition agent in cultivating water, and add once next month of generalized case, and can improve the output of soilless culture cucumber.
