Agricultural culture medium for growing tomatoes and preparation method thereof

Abstract

The invention relates to an agricultural culture medium for growing tomatoes and a preparation method thereof. The agricultural culture medium is prepared from the following raw materials in parts byweight: 80-100 parts of plant carbide, 70-90 parts of landscaping wastes, 60-80 parts of urban domestic sludge, 25-35 parts of straw powder, 20-30 parts of distiller grains, 15-25 parts of worm cast,10-20 parts of livestock and poultry manures, 6-10 parts of waste tea residue, 6-10 parts of polyacrylamide super absorbent resin, 3-8 parts of plant ash, and 15-25 parts of nutrient. The culture medium prepared through the method meets the growing requirements of grape in gas permeability of soil, nutrition slow release capability, PH, and nutrition content, and provides nutrients for tomato growing. The culture medium uses raw materials that are easy to obtain, the preparation method is simple and is easy to operate, and the culture medium is suitable for industrial production, is convenientto use, has obvious effect, can prevent diseases and increase yield, can balance plant nutrition, and greatly improves the tomato yield and quality.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to an agricultural cultivation substrate for tomato planting and a preparation method thereof. Background technique [0002] The quality of the soil directly affects the growth of crops. The soil currently used for farming mainly has the following problems: first, there are two extremes in the content of organic matter; The content of organic matter has been decreasing year by year; on the other hand, due to excessive supplementation of organic fertilizers in a small number of protected soils, the content of soil organic matter has seriously exceeded the appropriate range. The use of pesticides has increased year by year, and the pesticide residues in crop fruits have increased; the second is that plant nutrients are seriously unbalanced. Due to perennial fertilization and unreasonable soil utilization, some nutrients in the soil are seriously unbalanced, ...

[0002] The quality of the soil directly affects the growth of crops. The soil currently used for farming mainly has the following problems: first, there are two extremes in the content of organic matter; The content of organic matter has been decreasing year by year; on the other hand, due to excessive supplementation of organic fertilizers in a small number of protected soils, the content of soil organic matter has seriously exceeded the appropriate range. The use of pesticides is increasing year by year, and the amount of pesticide residues in crop fruits is increasing; the second is that plant nutrients are seriously unbalanced

With the continuous development of my country's tomato planting industry and the continuous expansion of the planting area, the use of cultivation substrates is also increasing. The traditional substrates prepared by single raw materials such as peat and wood chips or simply mixed can no longer meet the needs of planting.
