Abstract
The invention relates to a dual-layer sustain-released fertilizer capable of preventing peanut underground pests. The fertilizer is composed of the following components in percentage by weight: 45 to 75% of urea, 7 to 9% of ferrous sulfate, 15 to 20% of lime nitrogen, 6 to 8% of borax, 8 to 10% of ammonium chloride, and 15 to 19% of organic sustain-released fertilizer. The fertilizer can be prepared through the following steps: heating and melting urea, adding ferrous sulfate and lime nitrogen to prepare slurry, filling the slurry into a mould, cooling, moulding, separating, wrapping a thermally-shrinking degradable porous polyvinyl film on the separated large-particle fertilizer, then spraying water solutions of organic silicon sustain-released fertilizer, ammonium chloride, and borax on the surface of the large-particle fertilizer, drying, sieving, cooling, and packaging in bags. The prepared dual-layer sustain-released fertilizer is pollution-free and long-acting, and can save the labors and increase the peanut output during the production process of peanut.
Description
Technical field
The invention belongs to prevention and control Agricultural pests technical field of fertilizers, the double-layer sustained release being specifically related to a kind of anti-peanut soil pest is fertile.
Background technology
Peanut is important oil crops and cash crop, in China's edible oil materials production safety and increasing peasant income, occupy critical role.The subterranean pest-insects such as grub affect one of peanut yield principal element, particularly in recent years, due to the impact by factors such as straw-returning enlarged areas, tillage method and weather condition changes, the occurrence and harm of the subterranean pest-insects such as peanut field grub is more and more heavier, have a strong impact on the yield and quality of peanut, even have no harvest time serious.At present, China controls Peanut Fields subterranean pest-insect method and mainly uses the chemical pesticides such as Chlorpyrifos 94, Volaton, isofenphos_methyl, often causes that product middle peasant is residual to exceed standard, impact outlet and human consumer healthy.Conventional fertilizers due to particle little, melt water speed is fast, causes a large amount of fertilizer along with rain water runoff and volatilization, can not be fully absorbed by crops, and as peanut one season crop must score repeatedly go to apply fertilizer, take a lot of work.Therefore, explore pollution-free, long-acting, the fertile green organic fertilizer of double-layer sustained release of the subterranean pest-insect that saving of labor increases production again is peanut production urgent problem.
Summary of the invention
The present invention seeks to achieve in peanut production process pollution-free, long-acting, the effect that saving of labor increases production again.The double-layer sustained release providing a kind of anti-peanut soil pest is fertile, be made up of following material and be respectively by weight percentage: urea 45%-75%, ferrous sulfate 7-9%, lime nitrogen 15%-20%, borax 6-8%, ammonium chloride 8-10%, organosilicon slow-release fertilizer 15-19%, it is characterized in that, comprise following process, ferrous sulfate is added again with after Urea melting, lime nitrogen, the molten slurry of furnishing, pour into mold cools down shaping after the macrobead composite nitrogen fertilizer separated, at the pyrocondensation degradable polyethylene film that large-particle fertilizer outsourcing one deck is with holes, organosilicon slow-release fertilizer, ammonium chloride, the aqueous solution of borax is sprayed at above-mentioned large-particle fertilizer surface, sieve with 110-120 object sieve aperture while dry, cool packed.
The double-layer sustained release of above-mentioned a kind of anti-peanut soil pest is fertile, it is characterized in that, mold pressing 3-5min under control die temperature 70-110 DEG C, 55-250MPa, is cooled to room temperature forming.
Available silicon content >=15% in above-mentioned organosilicon slow release fertilizer.
The beneficial effect of the invention:
Can kill insect in soil because lime nitrogen can discharge cyanamide, organosilicon slow-release fertilizer, ammonium chloride can expel insect.By the pyrocondensation degradable polyethylene film of centre, fertilizer is divided into bilayer, outer field fertilizer first acts on soil, saves the man-hour of secondary fertilising.Internal layer fertilizer is slowly synergy As time goes on, is not easy along with along with rain water runoff and volatilization, can be fully absorbed by crops.Compared with reference examples, this invention all can improve per plant number 10.5%-26.5% on Spring Peanut and Peanut, kilogram fruit number reduce 4.8%-15.7%, worm bud decayed fruit number lowers 77.4%-93.5%, the method is also effective in plumpness and kernel percent etc. simultaneously, also very remarkable in this external effect of increasing production, every mu of volume increase 15.9%-20.1%, subterranean pest-insect double-layer sustained release fertilizer achieves pollution-free, long-acting in peanut production process, the effect that saving of labor increases production again.
