A high-efficiency chelating type liquid crop culture solution and its preparation method and application

Abstract

The invention belongs to the technical field of crop culture fluid, and in particular relates to a high-efficiency chelating type liquid crop culture fluid and its preparation method and application. The raw materials for the preparation of the high-efficiency chelating liquid crop culture solution consist of the following components by weight: 2-2.5 parts of potassium nitrate, 1.2-1.5 parts of ammonium dihydrogen phosphate, 3.5-3.8 parts of magnesium sulfate heptahydrate, and 0.1-3 parts of copper sulfate. 0.2 parts, 0.4-0.8 parts of sodium edetate, 0.05-0.1 parts of nutritional enhancer, 0.05-0.1 parts of hydrogen peroxide solution with a volume fraction of 3%, and 10,000-14,000 parts of water. The present invention respectively improves the culture solution and the culture method used for soilless cultivation, adds hydrogen peroxide solution while ensuring the basic nutrients needed for the growth of crops, and provides sufficient nutrients for the root system to promote the growth of crops. Adding hydrogen peroxide solution to the culture medium during seedling cultivation can also effectively promote the growth of wheat.

Description

technical field [0001] The invention belongs to the technical field of crop culture fluid, and in particular relates to a high-efficiency chelating type liquid crop culture fluid and its preparation method and application. Background technique [0002] Due to the limitation of the area of ​​fertile soil resources, the method of soilless cultivation of crops has become more and more popular in recent years. Soilless cultivation refers to using water, peat, vermiculite and other media as the substrate of the plant root system to fix the plant, and immersing the plant root system in various nutrient solutions. This cultivation method does not require soil and is not limited by the planting area. It is widely used, and because the formula of the nutrient solution used is obtained through long-term experiments or experience summarization, it can not only promote the efficient growth of plants, but also avoid excessive use of chemicals. Soil compaction caused by fertilizers. [...
