Organic compound fertilizer prepared from recycled by-products of agriculture, forestry and animal husbandry

Abstract

The invention discloses an organic compound fertilizer prepared from recycled by-products of agriculture, forestry and animal husbandry. The organic compound fertilizer contains the following raw materials in parts by weight: 50-80 parts of agricultural by-products, 50-80 parts of forestry by-products, 50-80 parts of animal husbandry by-products, 3-5 parts of amino acid, 2-5 parts of potassium phosphate, 1-5 parts of magnesium sulfate, 5-8 parts of borax, 3-5 parts of copper sulfate, 0.5-1.0 part of sodium molybdate, 0.5-1.5 parts of manganese sulfate, 0.5-2 parts of calcium nitrate and 1-2 parts of fulvic acid. According to the invention, the by-products of agriculture, forestry and animal husbandry are turned into wealth from waste, the by-products are mixed at a reasonable ratio and prepared into the recycled fertilizer and the cyclic utilization of the waste is realized.

Description

technical field [0001] The invention belongs to the field of technical fertilizers, in particular to an organic compound fertilizer for recycling by-products of agriculture, forestry and animal husbandry. Background technique [0002] Fertilizer is a kind of substance that provides one or more essential mineral elements for plants, improves soil properties and improves soil fertility level, and is one of the material basis of agricultural production. [0003] Fertilizers are crucial to increasing crop production. The nutrients necessary for higher plants include carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, boron, manganese, copper, zinc, molybdenum and chlorine, etc. 16 kinds element. These 16 essential nutrients can be divided into macronutrients, secondary nutrients and micronutrients because of their different content in crops. Macronutrients account for a few thousandths to tens of percent of dry matter in crops, such as ...

Problems solved by technology

However, the unreasonable application of chemical fertilizers has brought a series of problems to the quality of cultivated land for a long time. The actual utilization rate of chemical fertilizers is less than 30%, the problem of soil pollution is serious, and pollution accidents occur frequently. More than 10% of the cultivated land area in the country has been polluted by heavy metals. , about half of the arable land in some cities in South China is polluted by toxic heavy metals such as cadmium, arsenic, mercury, and petroleum-based organic substances
