Ecological granular fertilizer used for zucchini and capable of controlling phytophthora rot

Abstract

The invention discloses an ecological granular fertilizer used for zucchini and capable of controlling phytophthora rot. The ecological granular fertilizer comprises components of raw materials in parts by weight as follows: 40-50 parts of waste bean dregs, 30-40 parts of fermented chicken manure, 20-30 parts of urea, 4-6 parts of perlite, 5-7 parts of rice straw ash, 12-14 parts of potato vines, 3-5 parts of molasses residues, 1.2-1.4 parts of tea polyphenol, 0.6-0.8 parts of a phytophthora rot resisting microbial agent, 2-4 parts of microelements and 3-5 parts of ground phosphate rock. The phytophthora rot resisting microbial agent has a function of control of phytophthora rot, has remarkable pest killing and preventing effects and relieves injure of pests to crop root systems, the molasses residues, tea polyphenol and the ground phosphate rock have higher material water absorption stability, and an excellent soil environment is provided for growth of crops; the fermented chicken manure has high nutrition ingredients, the fertilizer absorption level of crops can be substantially improved, the crop resistance is enhanced, waste bean dregs are turned into wealth, the ecological granular fertilizer contains rich organic matters, alkali-hydrolyzable nitrogen, available phosphate, effective potassium and the like, the microelements provide required nutrition for growth of seedlings, and the product conversion rate is increased.

Description

Technical field [0001] The invention belongs to the technical field of fertilizers, and specifically relates to a zucchini ecological granular fertilizer for preventing and treating cotton rot. Background technique [0002] Cotton rot mainly damages fruits and sometimes leaves, stems and other parts. The fruit showed an oval, water-soaked dark green spot at the beginning of the disease. Under dry air conditions, the diseased spot is slightly sunken and does not expand quickly, only the subcutaneous pulp becomes rot, and a white mold layer is formed on the surface. In high temperature and humidity, the diseased spots spread rapidly, the whole fruit turns brown and soft, and the surface is covered with white mildew, causing the diseased melon to rot in the field. The leaves are damaged, the initial dark green, round formation of irregular water-soaked lesions, soft and rotting like boiling water when the humidity is high. [0003] Zucchini spongy rot is caused by the fungus Pythiu...

Problems solved by technology

But it also has some disadvantages, such as its nutrient ratio is always fixed, and the types, quantities and ratios of nutrient elements required by different soils and different crops are varied.

[0005] However, there are many varieties of biological fertilizers, microbial fertilizers, biological phosphate fertilizers, and biological potassium fertilizers in China. As the main fertilizer, with a single effect and high price, my country's microbial fertilizer industry still has problems of low overall level, insufficient technological innovation, and unstable product quality and application effect.
