Fertilizer special for winter jujubes

Abstract

The invention discloses a fertilizer special for winter jujubes. The fertilizer special for winter jujubes is prepared from, by weight, 34-36 parts of humus, 48-52 parts of silkworm excrement, 22-24 parts of bagasse, 3-4 parts of calcium acetate, 0.5-0.7 part of ferrous sulfate, 5-6 parts of ammonium dihydrogen phosphate, 2-3 parts of hydroxypropyl methylcellulose, 1-2 parts of gypsum powder, 8-10 parts of humic acidic ammonium, 26-28 parts of corn protein powder, 0.8-1.0 part of acrylamide, 0.1-0.2 part of maleic anhydride, 1.0-1.2 parts of ammonium persulfate, 15-17 parts of chitosan, 1.2-1.5 parts of zero-valent iron, 0.2-0.3 part of epoxy chloropropane, a proper amount of 0.5 % acetic acid solution, a proper amount of 0.5 mol / L sodium hydroxide solution and a proper amount of water. The fertilizer is used for winter jujube planting, the multiple added humic raw materials deepen the color of the fertilizer, the soil color can be deepened after application, heat absorption is promoted in winter, meanwhile the multiple added organic materials in the raw materials can ensure that enough biodegradable ingredients in soil, the temperament demand of the root portions of jujube trees can be also met by utilizing heat produced with organic matter degradation, and the growth stability of the winter jujubes is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special fertilizer for winter jujube. 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, which will lead to poor soil ...

Problems solved by technology

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.
