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

Embodiment Construction

[0017] A modified chestnut protein-coated slow-release fertilizer with strong stability and long action period, made of the following raw materials in parts by weight (kg): cottonseed cake 33, potassium dihydrogen phosphate 7, fermented glutinous rice 12, ferrous chloride 3 , tamarind polysaccharide gum 2, microcrystalline paraffin wax 1.4, fresh chestnut 78, Sapphire fruit 18, glutamine transaminase preparation 1.9, appropriate amount of water.

[0018] The specific steps of the preparation method of the modified chestnut protein-coated slow-release fertilizer with strong stability and long action period are as follows:

[0019] (1) Remove the bracts and shells of fresh chestnuts, slice them, dry them at 48°C, crush them, and add chestnut powder to water 10 times its mass, and use 1mol / L sodium hydroxide solution to adjust the pH to 9.8. Ultrasonic pulverization at 40kHz for 14 minutes, then heated to 40°C, kept for 65 minutes, filtered to take the supernatant, and vacuum fre...

Abstract

The invention discloses a good-stability long-action-period modified-Chinese-chestnut-protein-coated slow-release fertilizer. The fertilizer is made from the following raw materials, by weight part, 33-36 of cottonseed cake, 7-8 of potassium dihydrogen phosphate, 12-14 of fermented glutinous rice, 3-4 of ferrous chloride, 2-3 of tamarind seed polysaccharide gum, 1.4-1.5 of microcrystalline wax, 78-80 of fresh Chinese chestnuts, 18-20 of fruits of ficus pumila, 1.9-2.1 of a glutamine transaminase preparation and a proper amount of water. Through spraying for two times, the uniformity of coating films of fertilizer particles is greatly improved, so that stability of the fertilizer particles is improved and a slow-release period of the fertilizer in soil is prolonged. The fertilizer itself contains a large number of organic matters and readily-available inorganic nutrients, and can improve the nutrient construction and physical and chemical properties of the soil during a slow-release stage. The fertilization potential of the soil is improved, and crops are prompted to grow fast.

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 with strong stability and long action period. 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 Th...
