Abstract
The present invention provides a soil hardening preventing fertilizer, which can effectively prevent soil from hardening and can make the fertilized soil maintain the loose effect so as to promote crops to well absorb nutrients and moisture. Compared with the fertilizer in the prior art, the fertilizer of the present invention has the following characteristics that: polyacrylamide has good flocculation property, such that soil and impurities can be instantly adhered to form agglomerated particles so as to produce gaps between soil and achieve the loose effect; and experiment results show that the soil hardening phenomenon can be effectively prevented by applying the fertilizer of the present invention on the soil, such that the soil can maintain the loose effect.
Description
Technical field
The present invention relates to technical field of fertilizer production, more particularly, relate to fertilizer of keeping soil from packing together and preparation method thereof.
Background technology
China is a populous country, and grain-production occupies important position in the development of agriculture production.The approach of usual increase grain yield is brought more land under cultivation or increases the yield per unit area.According to China's actual conditions, continue the potentiality of bringing more land under cultivation not quite, although still there are many unreclaimed soils in China, mostly there is the problem that investment is many, difficulty is large, this just determines Grain in China and increases production the approach that must walk to increase the yield per unit area.
Fertilising can not only be increase soil fertility, and is the important measures improving crop yield per unit.Chemical fertilizer be agriculture production the most basic and also be most important material drop into.According to Food and Argriculture OrganizationFAO's statistics, chemical fertilizer accounts for 40% ~ 60% in total share of increasing crop yield.China can support the population in the Liao Zhan world 22% with the arable land accounting for the world 7%, can say that chemical fertilizer plays very important effect.
But chemical fertilizer can cause soil compaction usually in prior art, cause arable soil to harden, cause the fertilizer nutrient in soil and moisture better can not be absorbed by crop, and then reduce utilization rate of fertilizer and crop yield.Also there is no the fertilizer that effectively can solve soil compaction at present.
