Anti continuous and alternative-year special fertilizer for promoting crop yield and its preparing process

Abstract

This invention provides anti-weight yin cha advancing crop yield increasing special fertilizer. The fertilizer has nitrogen in plant nutrition elements, phosphor P205, kalium K20, middle microelement chelated additive T, their weight parts are as follow, P2O5:K2O:T equals to 1:2:0-5.0:0.429>=T>0.0, it also has titanium-ascorbic acid solid compound used as plant grow regulator, the compound adding on is 0.005-0.5 percent to the fertilizer weight. Its preparation technique is chemical synthesis oil cooling method. Titanium-ascorbic acid solid compound can improve plant absorbing to microelement, the function of titanium improving photosynthesis and synthesis of carbohydrate can be fully exerted, it can increase root nodule number, increase plant nitrogen-fixing capacity and resistibility to microorganism, it also has good production increasing function to crop growth. In this invention, the fertilizer is in plocoid state under high temperature, and this is good fertilizer efficiency to soil and crops. Granulation is realized by using oil cooling, oil temperature heat emission is slow, particle cooling is uniform, and pollution brought by coal heating can be reduced.

Description

technical field

[0001] The invention relates to a special fertilizer for resisting heavy stubble and promoting crop production and a preparation process thereof. Background technique

[0002] my country is a big country producing crops and vegetables, but there are currently serious obstacles to continuous cropping of the same crops or vegetables on the same piece of land, that is, the second year of planting is called "heavy crops or vegetables", and the third year of planting is called "stubble crops". or vegetables” are seriously damaged by diseases and insect pests, and there is a serious reduction in production.

[0003] In order to prevent the infestation of diseases and insect pests and reduce production, crop rotation is usually adopted, and highly toxic pesticides are applied for control at the same time. However, due to the limited land area, stubble turning is limited; when using highly toxic pesticides or chemical fertilizers containing highly toxic pesticides, w...
