Abstract
The present invention relates to a multicomponent long-acting fertilizer formed from water-absorbing substances, chicken manure or plant ash, urea, ammonium sulfate, ammonium phosphate, calcium superphosphate, potassium fertilizers and trace element fertilizers. The fertilizer has the obvious effect on resisting drought and increasing yield, and the multicomponent long-acting fertilizer can be used for grain, vegetables, fruits and economic crops.
Description
The present invention relates to a kind of multi-element compound fertilizer material.
At present, the chemical fertilizer proportion that agriculture production is used increases day by day, because the effect of chemical fertilizer, soil humus reduces, soil compaction, thus cause soil fertility to reduce, and water retention property also reduces day by day, therefore, except the amount of application of continuous increase chemical fertilizer, arid phenomenon also very easily takes place, cause crop in poor harvest, therefore press for a kind of fertilizer, it can increase the supply of fertilizer, guarantees the needed enough nutrients of plant, helps soil water-retaining again, protects fertilizer, help the growth of crop, guarantee the stable volume increase of crop.
CN 1035489 discloses a kind of composite chemical fertilizer of drought resisting, and the macromolecule resin that has adopted high suction absorbs high density chemical fertilizer solution as carrier, obtains described fertilizer.There are many defectives in a kind of like this fertilizer, and is too high as the vector contg of no fertilizer efficiency, so concentration of fertilizer can not be too high, and this fertilizer is under-supply early stage, and adaptive surface is not wide, and this in addition fertilizer cost is too high, is difficult to promote.This application is not especially made specifically clearly explanation to described fertilizer.
CN 1106775 discloses the fertilizer of preparations such as utilizing this water-absorbing resin and fertilizer.This application also exists more aforementioned defectives.
