Modified-Chinese-chestnut-protein-coated slow-release fertilizer for improving fertility of reclamation soil

Abstract

The invention discloses a modified-Chinese-chestnut-protein-coated slow-release fertilizer for improving the fertility of reclamation soil. The fertilizer is made from the following raw materials, by weight part, 5-6 of fish meal, 5-6 of calcium superphosphate, 37-38 of cornstalks, 12-14 of soy sauce residue, 3-4 of disodium octaborate tetrahydrate, 2-3 of guar gum powder, 68-72 of fresh Chinese chestnuts, 23-25 of fruits of ficus pumila, 1.5-1.7 of a glutamine transaminase preparation and a proper amount of water. The fertilizer aims at the reclamation soil having the characteristics of unbalanced distribution of nutrients and relatively poor physical properties. Through combination of organic matters, such as corn stalks and soy sauce residue, and inorganic matters, such as calcium superphosphate, an aggregate structure of soil is prompted to form and the physical structure of the soil is improved. A slow-release control effect of the fertilizer is utilized to achieve uniform fertility of the soil. The fertility of reclamation soil is recovered, and the use value of the soil is increased.

Description

technical field [0001] The invention relates to the technical field of slow-release fertilizers, in particular to a modified chestnut protein-coated slow-release fertilizer for improving the fertility of reclaimed soil. Background technique [0002] With the development of specialization, industrialization and scale of agricultural production in my country, the requirements of agriculture for fertilizer and soil fertility are constantly upgrading, while traditional fertilizers have restricted the sustainable development of agricultural planting due to their low nutrient utilization. The application of coated slow-release fertilizer is an effective way to solve this problem. However, at present, the coating materials of common coated slow-release fertilizers are mainly chemically synthesized non-degradable polymers, which are easily left in the soil and cause soil degradation and pollution. At the same time, the function of the coating material is single, usually only slow T...

Problems solved by technology

However, at present, the coating materials of common coated slow-release fertilizers are mainly chemically synthesized non-degradable polymers, which are easily left in the soil and cause soil degradation and pollution. At the same time, the function of the coating material is single, usually only slow The controlled release effect does not take into account the effects of water absorption, antibacterial, antioxidation, etc., and the practicability for different soil environments
