Organic-selenium-enriched microorganism organic composite fertilizer and preparation method thereof

Abstract

The invention discloses an organic-selenium-enriched microorganism organic composite fertilizer and a preparation method thereof. The organic-selenium-enriched microorganism organic composite fertilizer comprises the raw materials in parts by weight: 40-60 parts of selenium-enriched bombyx mori, 40-60 parts of selenium-enriched plant waste, 40-60 parts of selenium-enriched edible mushroom waste, 40-60 parts of minerals, 20-30 parts of vitamins and 1-10 parts of a composite fungicide. The organic-selenium-enriched microorganism organic composite fertilizer can supply enough minerals such as organic selenium and beneficial substances such as microorganisms and probiotics to the growth of crops; meanwhile, the fertilizer can improve the soil, prevent diseases, and realize sterilization; a large amount of waste is turned into treasures, so that social and natural resources are saved, the environment is protected, and cyclic economy is realized. The organic-selenium-enriched microorganism organic composite fertilizer is one of the best fertilizers for producing pollution-free food, green food and organic food.

Description

technical field [0001] The invention relates to a fertilizer, in particular to an organic selenium-rich microbial organic compound fertilizer and a preparation method thereof. Background technique [0002] At present, in terms of crop planting in my country, most of them still use chemical fertilizers. Although they have a certain effect on increasing production and income, long-term application will cause many disadvantages: [0003] 1. Destroy the soil, resulting in a decrease in soil organic matter content, an imbalance in the proportion of various nutrients, soil acidification and compaction, and serious damage to the physical and chemical properties of the soil and soil microbial flora, resulting in poor water retention, fertilizer retention, and air permeability, making it difficult to meet the needs of crops. actual growth needs; [0004] 2. Crops are highly dependent on chemical fertilizers and pesticides, and the amount of use must be increased year by year, ot...

Problems solved by technology

[0003] 1. Destroy the soil, resulting in a decrease in soil organic matter content, an imbalance in the proportion of various nutrients, soil acidification and compaction, and serious damage to the physical and chemical properties of the soil and soil microbial flora, resulting in poor water retention, fertilizer retention, and air permeability, making it difficult to meet the needs of crops. actual growth needs;

[0004] 2. Crops are highly dependent on chemical fertilizers and pesticides, and the amount of use must be increased year by year, otherwise, the crops will grow slowly, and the pests and diseases will be serious, resulting in reduced production;

[0005] 3. The agricultural ecological environment is deteriorating. After chemical fertilizers are applied to the farmland, the actual utilization rate is only 30% on average. Most of them flow into rivers and lakes with farmland drainage or remain in the soil, plants and crops, which not only brings environmental pollution but also endangers the safety of human beings and lives. and health, which are obstacles to sustainable agricultural development;

[0007] The above situations can be improved by applying organic fertilizers. However, there are many varieties of biological fertilizers, microbial fertilizers, biological phosphate fertilizers, and biological potassium fertilizers in China. Livestock manure is used for processing, and the application amount is very small, which cannot be used as the main fertilization, and the effect is single, and the price is high; in addition, with the improvement of people's living standards, selenium-enriched rice, selenium-enriched tea and other selenium-enriched agricultural products are also becoming more and more popular. more popular
