Nutritional additive for improving water and soil in seedling stage and preparation method thereof

Abstract

The invention discloses a nutritional additive for improving water and soil in the seedling stage. The nutritional additive is composed of the following components in parts by weight: 24 to 26 parts of bentonite, 21 to 22 parts of brown sugar, 4 to 5 parts of critic acid, 10 to 12 parts of phosphor nitrate fertilizer, 22 to 24 parts of soybean powder, 23 to 26 parts of rapeseed cake powder, 6 to 8 parts of ferrous sulfate, 42 to 45 parts of volcanic rock, 12 to 16 parts of aged tea, 63 to 67 parts of waste crop straws, 15 to 20 parts of threonine mother liquor, 3 to 5 parts of composite fungal hyphae, and a proper amount of water. The porous structure, which is obtained by mixing fungus dregs and bentonite, of the nutritional additive can improve the water content and water holding capacity of soil for breeding seedlings; moreover, the irrigation amount in the period stage can be reduced, the root will not be destroyed by excess water, the organic substances in the fungus dregs can cooperate with the chelating liquid to improve the pH value of soil, at the same time, the organic microbe number and organic substance content of soil are greatly increased, and thus the crop growth in the seedling stage can be promoted.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a nutrient additive for improving water and soil at the seedling stage and a preparation method thereof. Background technique [0002] The growth and development of crops can be divided into three stages: seedling stage, growth stage and mature stage. The nutritional characteristics refer to the proportion of nutrient requirements in different stages, and are directly related to the level of crop yield. The seedling stage is a sensitive period for crops to require fertilizer. The nutritional status at this stage, especially nitrogen supply, is of great significance to its growth. It not only affects the nutritional level in the middle and later stages, but also determines the final yield level of the crop. [0003] Macrofungus refers to fungi that can be harvested by hand and can produce large fruiting bodies. Beneficial fungi have a synergistic effect and can jointly promot...

Problems solved by technology

[0004] Since the seedling stage of crop growth is short and requires less nutrients, there are few nutrient additives for crop seedling stage on the market, and they are mainly inorganic fertilizers. Long-term use not only causes nutrient imbalance, but also due to extremely low utilization The rate has led to the pollution of the soil environment, endangering crop growth and human health
