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 special for rice, which is made of the following parts by weight (kg) of raw materials: furfural residue 25, disodium edetate 2.4, borax 3, vinegar grains 14, xanthan gum 1 , Potassium silicate 2, Attapulgite powder 4, Fresh Chinese chestnut 78, Ficus pumila 18, Transglutaminase preparation 1.1, Appropriate amount of water.

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

[0019] (1) The fresh chestnut is de-husked and sliced, dried at 48°C, crushed and finely ground, and the chestnut powder is added to 10 times its mass in water, and the pH is adjusted to 9.8 with 1mol / L sodium hydroxide solution. Ultrasonic pulverization at 35kHz for 15 minutes, then heating to 40°C, holding for 80 minutes, filtering to take the supernatant, and vacuum freeze-drying to obtain chestnut protein powder;

[0020] (2) Put the discarded chestnut...

Abstract

The invention discloses a modified-Chinese-chestnut-protein-coated slow-release fertilizer special for rice. The fertilizer is made from the following raw materials, by weight part, 25-28 of furfural residue, 2.4-2.5 of disodium ethylene diamine tetraacetate, 3-4 of borax, 14-16 of vinegar residue, 1-3 of xanthan gum, 2-3 of potassium silicate, 4-5 of attapulgite powder, 78-82 of fresh Chinese chestnuts, 18-20 of fruits of ficus pumila, 1.1-1.2 of a glutamine transaminase preparation and a proper amount of water. The fertilizer aims at characteristics of nutrient requirements and absorption during rice growth. Nutrients reasonably match, and stability of a modified protein coat ensures that fertilizer particles are not prone to disintegrate in wet soil. Through addition of potassium silicate, disodium ethylene diamine tetraacetate, and the like, the ability of absorbing mineral elements and microelements of rice is improved, thereby improving lodging resistance and insect resistance of rice and reducing administration cost and fertilizer cost in a farm land of rice.

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 special for rice. Background technique [0002] With the development of specialization, industrialization, and large-scale agricultural production in my country, the requirements of agriculture for fertilizer and soil fertility have been continuously upgraded. However, 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 rel...
