Organic fertilizer capable of improving soil

Abstract

The invention discloses an organic fertilizer capable of improving soil. The organic fertilizer is prepared from the following components in percentage by mass: 3%-6% of waste vegetable leaves, 2%-5% of animal bones, 0.4%-0.8% of eggshell, 2%-4% of watermeion peel, 0.2%-0.5% of fructus cnidii, 0.1%-0.5% of liquorice root and yellowish sophora root, 1%-5% of platycodon grandiflorum, 1%-3% of plant ash, 3%-8% of animal manure, 3%-6% of peanut cakes, 2%-4% of margaryamelanoides, 0.005%-0.008% of onionskin, 10%-20% of river sludge, 1%-5% of walnut shell, 1%-2% of dry sea-tangle and the balance of rice washing water. By twice sealed heating fermentation, the carbon content can be reduced; the nitrogen-carbon ratio is improved; sterilization and disinfection can be carried out; the organic fertilizer is reasonable in process, scientific in preparation, complete in nutrient, reasonable in proportion, high in crop absorption rate and high in sustainable ability; the utilization rate of nutrients of the fertilizer can be effectively improved; and the nutrient requirements of crops can be met.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizers, and in particular relates to an organic fertilizer for improving soil. Background technique [0002] Over the years, the application of chemical fertilizers has played a very important role in increasing agricultural production and income. Agricultural production requires soil to provide nutrients and a living environment for crop growth and reproduction. However, due to long-term application of chemical fertilizers, the supply of organic fertilizers is insufficient, and various types of nutrients The proportion of soil and stool is out of balance, resulting in different degrees of damage to the farmland ecological environment, soil physical and chemical properties, and soil microbial flora, which affects the quality of agricultural products to a large extent. Taking the black soil area in Northeast China as an example, the soil organic matter has been reduced from the level during...

[0002] Over the years, the application of chemical fertilizers has played a very important role in increasing agricultural production and income. Agricultural production requires soil to provide nutrients and a living environment for crop growth and reproduction. However, due to long-term application of chemical fertilizers, the supply of organic fertilizers is insufficient, and various types of nutrients The proportion of soil and stool is out of balance, resulting in different degrees of damage to the farmland ecological environment, soil physical and chemical properties, and soil microbial flora, which affects the quality of agricultural products to a large extent. Taking the black soil area in Northeast China as an example, the soil organic matter has been reduced from the level during reclamation. 8-10% drops to 2-3%, from organic-rich soil to organic-poor soil, and the situation of soil organic matter in other areas is even more serious. Experts point out that chemical fertilizer pollution has become a major public hazard in the world today. Objective The current situation of soil resources urgently needs to supplement soil organic matter through artificial measures to ensure the level of agricultural planting and the quality of crop products
