Special anti-fruit-cracking fertilizer for jujube trees

Abstract

The invention discloses special anti-fruit-cracking fertilizer for jujube trees. The special anti-fruit-cracking fertilizer is prepared from the following raw materials in parts by weight: 42 to 46 parts of sesame meal, 25 to 26 parts of wheat bran, 3 to 4 parts of ferric sodium ethylene diamine tetraacetate, 0.6 to 0.8 part of manganese sulfate, 6 to 7 parts of ammonium sulfate, 1 to 2 parts of calcium gluconate, 1 to 2 parts of bone glue, 3 to 4 parts of attapulgite powder, 24 to 26 parts of corn protein powder, 0.5 to 0.6 part of acrylamide, 0.1 to 0.2 part of maleic anhydride, 0.4 to 0.5 part of ammonium persulfate, 16 to 17 parts of chitosan, 0.6 to 0.7 part of nano zero-valent iron, 0.1 to 0.2 part of epichlorohydrin, a proper amount of 0.5 percent acetic acid solution, a proper amount of 0.5mol / L sodium hydroxide solution and a proper amount of water. According to the special anti-fruit-cracking fertilizer for the jujube trees, disclosed by the invention, fertilizer nutrients are supplied in a balanced manner; the ferric sodium ethylene diamine tetraacetate, the manganese sulfate and the like are utilized so that the requirements of jujube pericarps on microelements can be met; meanwhile, organic calcium salt including the calcium gluconate and the like are added so that the cell toughness of jujube fruits and pericarps can be enhanced; furthermore, the integrity of the pericarps is ensured and the aim of preventing fruit cracking is realized.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special fertilizer for jujube trees that prevents fruit cracking. Background technique [0002] Jujube, also known as jujube, is an important edible and medicinal economic crop in my country. Due to its drought resistance, waterlogging resistance and strong adaptability, it is the first choice for the development of water-saving forestry and fruit industry, and it is also the economic income of more farmers. main source of . The use of fertilizers in the process of jujube planting plays a key role in the yield and quality of jujubes, but there are many defects in the jujube fertilizers currently available in the market. Provide a large amount of nutrients such as nitrogen and phosphorus; second, chemical fertilizers are mainly used, supplemented by organic fertilizers, which easily produce chemical residues and pollute the environment; third, they cannot improve the soil, w...

The use of fertilizers in the process of jujube planting plays a key role in the yield and quality of jujubes, but there are many defects in the jujube fertilizers currently available in the market. Provide a large amount of nutrients such as nitrogen and phosphorus; second, chemical fertilizers are mainly used, supplemented by organic fertilizers, which easily produce chemical residues and pollute the environment; third, they cannot improve the soil, which will lead to poor soil in the long run and are not suitable for Planting; Fourth, the utilization rate of fertilizers is low, which leads to excessive waste of available resources when resources cannot be reused

[0004] Zein is a kind of renewable and biodegradable natural plant protein. It has the characteristics of low cost, convenient processing and no irritating smell. It has been widely used in tissue engineering and medicine. There is no in-depth research on the application. The modification of zein and the introduction of some functional monomers can increase the water resistance and stability of zein as a coating material, which has great application potential in the preparation of fertilizers.
