Modified-Chinese-chestnut-protein-coated slow-release fertilizer suitable for red soil of dry land

Abstract

The invention discloses a modified-Chinese-chestnut-protein-coated slow-release fertilizer suitable for red soil of a dry land. The fertilizer is made from the following raw materials, by weight part, 25-28 of wheat bran, 4-5 of ammonium nitrate, 1-2 of calcium lactate, 12-14 of cassava residue, 7-8 of pig bone meal, 6-7 of a calcium-magnesium-phosphate fertilizer, 1.8-2.0 of guar gum powder, 76-80 of fresh Chinese chestnuts, 14-16 of fruits of ficus pumila, 1.5-1.8 of a glutamine transaminase preparation and a proper amount of water. The fertilizer aims at red soil having the characteristics of a low organic matter content and deficient readily-available phosphorus. Through use of fermented materials including wheat bran and cassava residue, particles of red soil are improved, the organic matter content of the red soil is increased, and the nitrogen fertility of the red soil is improved. Readily-available phosphorus, such as the calcium-magnesium-phosphate fertilizer, is added and can greatly increase the yield of planting in the red soil. Through use of high-water-retention materials, such as powdery Chinese chestnut carbon, matching a modified-protein coat, the nutrient and water content of the red soil of the dry land can be followed up in real time. Stable and high-yield production of crops is promoted and the fertilizer has an excellent effect.

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 suitable for dry red 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 The controlled-releas...

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
