A vegetable organic composite fertilizer and a preparing method thereof

Abstract

The invention discloses a vegetable organic composite fertilizer and a preparing method thereof, and relates to the field of vegetable plantation fertilizers. Raw materials of the composite fertilizer include decomposed organic matters, charcoal, silkworm excrement, straw ash, potassium citrate, sodium alginate, chelated trace elements, a microbial agent, an adhesive, a chelating agent and a granulation auxiliary agent. The method includes firstly adding water into the potassium citrate, the sodium alginate, the chelated trace elements, the microbial agent, the adhesive and the chelating agent to form a solution mixture, heating the solution mixture, adding other raw materials into the solution mixture, fully mixing the mixture, and preparing the fully mixed mixture into organic granules. The organic composite fertilizer is simple to prepare, easily available in raw material and low in cost. The organic composite fertilizer is capable of increasing quality and yields of vegetables, increasing contents of sulforaphene in vegetables, and reducing enrichment of heavy metals and nitrate contents in vegetables, and is green, pollution-free and suitable for popularization and application.

Description

technical field [0001] The invention relates to the field of vegetable planting fertilizers, in particular to a vegetable organic compound fertilizer and a preparation method thereof. Background technique [0002] Vegetables are rich in vitamins, and they are eaten in large quantities in people's daily life. They are equally important in human diet structure, and their output and planting area have an obvious upward trend. It occupies an important position in the people's livelihood and the national economy. The economic benefits of vegetables depend on the yield and production costs of vegetables. The high quality of vegetables is the goal that people pursue unremittingly. Effective use of limited land resources, improving the yield and quality of vegetable crops is the direction of people's efforts. [0003] There are many types of vegetable fertilizers with different effects. Some fertilizers can improve the quality and yield of vegetables, while others will affect th...

AI Technical Summary

Problems solved by technology

Some chemical fertilizers can improve the quality and yield of vegetables, while some fertilizers will affect the quality and yield of vegetables after application. Although some chemical fertilizers can increase the yield of vegetables, they will cause serious chemical toxins to vegetables and the soil where they are planted. Pollution, which in turn causes food poisoning, and even damage to the ecological environment

[0004] Ammonium nitrate and other nitrate nitrogen fertilizers are generally not suitable for application to vegetables. After nitrate nitrogen fertilizers are applied to vegetable fields, the nitrate content in vegetables will double. Nitrate is easily reduced to nitrite in the human body. Nitrite is A carcinogen that is extremely harmful to the human body

Ammonium chloride, potassium chloride and other chloride-containing fertilizers should not be applied to tomatoes, potatoes, sweet potatoes and other chlorine-containing fertilizers. After decomposition in the soil, ammonium or potassium ions will be absorbed by the soil and absorbed by vegetables. When the concentration reaches a certain level, it will Toxic to the root system of vegetables, serious will cause the death of vegetables
