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] An anti-caking modified chestnut protein coated slow-release fertilizer, which is made of the following parts by weight (kg) of raw materials: fresh chicken manure 32, monoammonium phosphate 6, guar gum powder 3, charcoal 13, xylose Powder 5. Fatty acid zinc 1.1, Fresh chestnut 85, Ficus pumila 25, Transglutaminase preparation 1.9, Water appropriate.

[0018] The specific steps of the method for preparing the anti-caking modified chestnut protein coated slow-release fertilizer are as follows:

[0019] (1) Cut fresh chestnuts after de-husking and hulling, drying at 48°C, pulverizing and pulverizing, adding chestnut powder to 10 times its mass in water, and using 1mol / L sodium hydroxide solution to adjust the pH to 9.8. Ultrasonic pulverization at 35kHz for 14 minutes, then heating to 40°C, keeping the temperature for 80 minutes, filtering the supernatant, and vacuum freeze-drying to obtain chestnut protein powder;

[0020] (2) Put the discarded chestnut buds and chestnut shell...

Abstract

The invention discloses an anti-caking modified-Chinese-chestnut-protein-coated slow-release fertilizer. The fertilizer is made from the following raw materials, by weight part, 32-33 of fresh chicken manure, 6-8 of monoammonium phosphate, 3-4 of guar gum powder, 13-15 of charcoal, 5-6 of xylose powder, 1.1-1.3 of zinc fatty acid, 85-88 of fresh Chinese chestnuts, 25-28 of fruits of ficus pumila, 1.9-2.3 of a glutamine transaminase preparation and a proper amount of water. The outer surfaces of fertilizer particles are sprayed for two times, thereby improving uniformity and smoothness of a coating film. The fertilizer particles have looseness of a high degree, so that loss of the fertilizer efficiency and use inconvenience due to binding are prevented. Materials, such as fresh chicken manure and charcoal, are thoroughly decomposed and mixed with powdery Chinese chestnut carbon, so that the fertilizer can provide nutrients and inhibit growth of germs. The anti-caking slow-release fertilizer is eco-friendly.

Description

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