Anti continuous and alternative-year spcial fertilizer for promoting crop yield

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. In this invention, absorptivity is high, sublimation activity of enzyme inside plant body can be greatly improved, plant chlorophyll forming and nitrogen, phosphor and kalium absorbing can also be improved, plant root system activity and growth can be improved, crop photosynthesis can be improved and crop anti inverse ability and damage by disease and insect can also be improved. This invention can increase root nodule number, increase plant nitrogen-fixing capacity and resistibility to microorganism, frequency of processing plant can be reduced, it also has good production increasing function to crop growth.

Description

Technical field

[0001] The invention relates to a compound fertilizer, in particular to a special fertilizer for resisting repeated cropping and promoting crop yield during continuous cropping and alternate cropping. Background technique

[0002] my country is a large country producing crops and vegetables, but there are serious obstacles to continuous cropping of the same crops or vegetables on the same field. The second year is called "continuous crops or vegetables" and the third year is called "alternate crops". "Or vegetables" are severely affected by pests and diseases, resulting in a serious reduction in production.

[0003] In order to prevent pests and diseases and reduce production, crop rotation is usually adopted, and highly toxic pesticides are applied at the same time. However, due to the limited land area, the stubble is restricted; when highly toxic pesticides or medicinal fertilizers containing highly toxic pesticides are applied, pesticide residues are inevitabl...
