Nutrient solution for preventing diseases and insect pests of tomatoes and preparation method of nutrient solution

Abstract

The invention discloses a nutrient solution for preventing diseases and insect pests of tomatoes and a preparation method of the nutrient solution. The nutrient solution is mainly prepared from the following components in parts by mass: 15 to 25 parts of corn bran, 20 to 40 parts of straw, 2 to 5 parts of watermelon peel, 1.5 to 3.2 parts of manganese sulfate, 1 to 2 parts of boric acid, 4 to 8 parts of zinc sulfate, 8 to 15 parts of calcium superphosphate, 8 to 15 parts of ferric sodium EDTA (Ethylene Diamine Tetraacetate), 1 to 2 parts of ammonium molybdate and 5 to 15 parts of fungus clump.According to the preparation method of the nutrient solution disclosed by the invention, the nutrient solution for preventing the diseases and insect pests of the tomatoes is prepared by taking the corn bran, the straw and the watermelon peel as fermentation raw materials for culturing endophyte and then mixing the manganese sulfate, the boric acid, the zinc sulfate, the calcium superphosphate, the ferric sodium EDTA and the ammonium molybdate. According to the preparation method of the nutrient solution disclosed by the invention, the endophyte is cultured by utilizing agricultural waste, and can enhance the disease and inspect pest preventing ability of the tomatoes.

Description

technical field [0001] The invention belongs to the technical field of tomato nutrient solution, and in particular relates to a tomato nutrient solution for preventing diseases and insect pests and a preparation method thereof. Background technique [0002] Tomatoes refer to tomatoes grown in accordance with the production methods of organic agriculture. During the entire production process of tomatoes, the production technical standards of organic food must be strictly followed, that is, no pesticides, chemical fertilizers, growth regulators and other chemical substances are used in the production process. The use of genetically modified engineering technology must also go through the whole process of quality control and review by an independent organic food certification agency to ensure its pollution-free, nutritious and high-quality characteristics. [0003] Nutrient solution is a new type of ecological compound fertilizer formed by mixing pesticides and fertilizers in a...

Problems solved by technology

For tomatoes, the existing nutrient solutions cannot meet the requirements. Not only the absorption rate of tomatoes is not high, but also a large amount of drug residues are caused. When a large amount of inorganic fertilizers and drugs are used, the salinization of the soil is aggravated, which not only damages the environment, but also leads to follow-up tomatoes. production has dropped significantly
