Description
Technical field
The present invention relates to one for agricultural land soil conditioning agent and the composite mixture of chemical fertilizer thereof, particularly relate to one and be suitable for arid and semi-arid Farmland water-loss reducer of soil.
Background technology
China's arid, it is more than half that semiarid zone area accounts for national land area, be positioned at Kun Lun Mountain to the north of one line of---Qinling Mountains---Huaihe River, comprise 15 provinces in the north, city, autonomous region, grain, cotton, oil ultimate production accounts for respectively 37.5% of all kinds of national ultimate productions, 58% and 40%, this region is vast in territory, resource water shortage problem is outstanding, 300 ~ 700 millimeters of average annual precipitations, 70% ~ 80% rainfall occurs in for 6 ~ September, spring drought is very serious, due to weather and artificial origin, soil desertification, degenerate serious, crop yield is low and unstable, precipitation utilization ratio is generally only in 45% ~ 50% left and right, view of water technology popularity rate is low.Dry farming and water-saving irrigation is in arid, makes full use of the agriculture production that precipitation carries out on farmland in semi-arid area, comprises that rain supports and supplementary irrigation with catchment rainfall, improve to greatest extent precipitation and protect and hold rate, utilization ratio and utilising efficiency, thereby it is efficient to realize agricultural year.Following China grain, cotton, the important locality of oil will present north regional concentrated trend gradually, how efficiently to utilize precipitation, strengthen energetically arid, the development of semiarid zone dry farming and water-saving irrigation, become the Major Strategic approach that solves this area's shortage of water resources, therefore, should pay attention to the development and application of view of water gordian technique promotes, suit measures to local conditions to develop applicable view of water practical technique, comprising physical mechanical method, as adopt agricultural machinery to carry out soil to loosen the soil and can expand Soil Reservoir storage capacity, increase soil water storage ability, adopt earth's surface soverlay technique can greatly reduce the invalid evaporation of soil, also can pass through chemical control method, adopting soil water-retaining preparation to receive soil moisture slow release to wait is all the gordian technique of view of water, but these technology also have its limitation, carry out soil physics subsoiling and can consume a large amount of farming operation manpowers and energy consumption, and long-term incorrect Subsoiler can cause extruding that farmland plough sole often ploughed and precipitation time glutinous grain long-pending with depositing in water, form consolidation layer, cause sheet structure or large blocked structure, soil porosity is little, ventilation, water-permeable is bad, topsoil attenuation, cause water not infiltrate to deep subsoil, crop root is taken root the problems such as simple and easy lodging, carry out cannot carrying out Subsoiler after membrane covering, easily cause that soil high-temperature under film hardens, ventilation property is poor, using water-holding agent is also in the situation that having water, to carry out water conservation, when as few in soil water storage, water retention property is naturally poor, limited its use in arid, semiarid zone, in addition, subsoiling and water conservation are operation process independently separately, it should be again continuous operation process, it is integrated continuously that prior art or product still can not be realized subsoiling and water conservation, in retaining process, cannot realize chemical water conservation, thus the utilize effect of impact to precipitation and the soil water.
Summary of the invention
The object of the invention is the deficiency existing in above-mentioned technology, provide one to be suitable for arid and semi-arid Farmland water-loss reducer of soil.Realize by applying chemicals the effect of loosening the soil, overcome existing preparation and be difficult to solve the difficult problem that physics subsoiling and chemical water conservation can not be taken into account simultaneously, solve the problem that covers water-saving culture and cannot carry out loose soil, not only make the process implementation timely water conservation of soil in subsoiling, can make again water-holding agent there is the effect of water storage function, for utilizing to greatest extent precipitation and the soil water that new product is provided, for arid, semiarid zone provide a kind of multifunction farm water-loss reducer of soil.
The object of the present invention is achieved like this: be made up of polyvinyl alcohol, dodecyl aliphatic alcohol polyethenoxy (3) ether ammonium sulfate, dodecyl alcohol polyoxyethylene (9) ether, triacontanol price quote, n-Octanol, polyacrylic acid, Secondary ammonium phosphate, potassium sulfate, xanthohumic acid, indolebutyric acid, magnesium sulfate, water, be mixed in proportion, stir, filter and obtain product.Its compositing formula (by weight) is as follows:
2 ~ 8 parts of polyvinyl alcohol
0.5 ~ 1 part of dodecyl aliphatic alcohol polyethenoxy (3) ether ammonium sulfate
0.1 ~ 0.5 part, dodecyl alcohol polyoxyethylene (9) ether
0.001 ~ 0.008 part of triacontanol price quote
