Compound fertilizer

Abstract

The invention provides a compound fertilizer which comprises the following components in parts by weight: 50-70 parts of earthworm dejection, 10-30 parts of alfalfa roots (particle size of below 0.2cm), 5-15 parts of moss plants (particle size of below 0.2cm) and 5-15 parts of plant ash. The compound fertilizer has the advantages of organic fertilizers and inorganic fertilizers, is rich in organic matters and humic acid, has abundant ingredients and lasting fertilizer efficiency and can effectively improve soil, fertilize soil productivity, retain soil moisture and be applicable to long-term use; the compound fertilizer has no toxicity, no harm and no pollution and can not only overcome the shortcomings of dirty, smelly and unhygienic properties of other inorganic fertilizers, such as human, livestock and poultry manure, slow fertilizer efficiency, inconvenient use and the like, but also overcome the shortcoming of single ingredient of the inorganic fertilizer; and the compound fertilizer is particularly applicable to production of green agricultural products, and can not only improve the output of the products, but also improve the quality of the products.

Description

Technical field: [0001] The invention relates to a fertilizer, in particular to a compound fertilizer. Background technique: [0002] Chinese farmers have a tradition of using organic fertilizers. The United States, Western Europe, Japan and other developed countries are also emerging "ecological agriculture" and "organic agriculture", attaching great importance to the use of organic fertilizers, and specifying organic fertilizers as the main fertilizer source for the production of green food. [0003] Organic fertilizers are rich in organic matter and various nutrients, and have the advantages of large quantity, wide sources, and comprehensive nutrients, but they also have disadvantages such as low nutrient content, difficult decomposition, and slow fertilizer efficiency. The preparation and use of traditional organic fertilizers are also inconvenient. Human, livestock and poultry manure, garbage and other organic waste are dirty, rotten and smelly substances, which conta...

AI Technical Summary

Problems solved by technology

[0003] Organic fertilizers are rich in organic matter and various nutrients, and have the advantages of large quantities, wide sources, and comprehensive nutrients, but there are also disadvantages such as low nutrient content, difficult decomposition, and slow fertilizer efficiency.

The preparation and use of traditional organic fertilizers are also inconvenient

Human, livestock and poultry feces, garbage and other organic waste are dirty, rotten and smelly substances, which contain many pathogenic microorganisms, or are mixed with some poisonous substances, and are important sources of pollution. If they are used as organic fertilizers in farmland, they will seriously pollute the environment. affect people's health

[0004] Inorganic fertilizers are just the opposite of organic fertilizers. They have the advantages of high nutrient content, fast fertilizer efficiency, and convenient use, but they have the disadvantage of single nutrient.
