Background technology
With the development of science and technology, the continuous improvement of the transformation of social progress and people's life idea and living standard,
People are higher and higher to the pursuit of food, clothing, housing and transportation, and green, ecological, organic, environmentally friendly life will be that following people's life must
Must；Therefore organic agriculture, popularizing planting organic paddy rice, the green supply for ensureing people's dining table are greatly developed, is current and not
Carry out the developing direction of agricultural production.
There are shortcomings when planting organic paddy rice for existing technology, and often fertilizer efficiency is poor, and soil is easily hardened, low output,
Influence the planting benefit of farmer.
Invention content
Technical problems based on background technology, the present invention propose a kind of compound fertilizer preparation improving rice yield
Method, gained compound fertilizer is not only full of nutrition, and fertilizer and water conservation capacity is strong, fabulous to the slow release effect of nutriment, Er Qiegai
Kind soil hardening caused by since chemical fertilizer is used for a long time increases the permeability of soil, while can be provided for rice largely after degrading
Element silicon, at low cost, increasing of quality and production significant effect.
A kind of compound fertilizer preparation method improving rice yield proposed by the present invention, includes the following steps：
S1, p-aminophenyl trimethoxy silane, calcium lignosulfonate, water are uniformly mixed, regulation system pH value is 4-
4.8, it stirs, filters, wash, centrifuge, it is dry, tetrahydrofuran is added and stirs evenly, maleic anhydride stirring is added, precipitates, filtering,
Washing, is dried to obtain first material；
S2, first material addition Macrogol 600 is uniformly mixed, regulation system pH value is 3-3.8, is stirred, centrifugation, mistake
Filter, washing, vacuum drying obtain second material；
