Disease-resistant fertilizer composition for tomatoes

Abstract

The invention relates to a disease-resistant fertilizer composition for tomatoes. The disease-resistant fertilizer composition for the tomatoes consists of urea, monoammonium phosphate, potassium sulfate or potassium chloride, gypsum, magnesium sulfate monohydrate, sodium bicarbonate, an active agent and attapulgite clay. Control tests of the disease-resistant fertilizer composition for the tomatoes and the conventional fertilizer show that the quantity and the ratio of knot nematodes of the tomatoes are obviously reduced, the knot nematodes are prevented and controlled obviously, the growth index of the tomatoes is effectively improved, the activity of tomato leaf protective enzyme is improved, and the disease resistance of the tomatoes is improved obviously.

Description

【Technical field】 [0001] The invention belongs to the field of agricultural technology. More specifically, the present invention relates to a tomato disease-resistant fertilizer composition. 【Background technique】 [0002] Vegetable products produced in strict accordance with the operating procedures of harmless production technology in a production base that meets certain standards are called pollution-free vegetables. The air, soil, irrigation water and other environmental conditions of this vegetable production base have been tested by relevant departments and all meet the relevant standards. In the process of vegetable production, the use of highly toxic and high-residue pesticides is strictly prohibited, and the use of low-toxicity and low-residue pesticides is limited and limited, and biological methods are advocated to treat diseases and insect pests, minimize the application of chemical fertilizers, and increase the use of organic fertilizers. The content of toxic ...

Problems solved by technology

[0003] ① Safe use of pesticides needs to be strengthened

[0005] ② Rational use of chemical fertilizers needs to be improved

[0006] Some vegetable farmers are influenced by the concept of "the more fertilization, the higher the yield". The input of chemical fertilizers is too large, and the balanced application of chemical fertilizers cannot be achieved, resulting in soil salt accumulation and nitrate pollution, making it difficult to produce high-quality vegetables with nitrate content that does not exceed the standard.

[0007] ③Difficulty in carrying out the detection of pesticide residues in pollution-free vegetables

[0014] The continuous cropping of vegetables leads to serious soil-borne diseases such as vegetable and nematode diseases, resulting in a decrease in vegetable yield and quality
