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

Embodiment Construction

[0019] specific implementation plan

[0020] The present invention will be described in further detail below in conjunction with the following specific embodiments:

[0021] Weigh the following raw materials (kg): weathered coal 20, ammonium dihydrogen phosphate 12, cottonseed cake 22, soot residue 22, manganese sulfate 5, rice bran 24, polymethacrylic acid 2, volcanic rock 42, waste crop straw 65 , threonine mother liquor 15, aged tea leaves 21, composite fungal hyphae 5, appropriate amount of water;

[0022] The composite fungal mycelium is boletus mycelium, VA mycorrhizal agent, orange yellow mushroom mycelium and albocystium mycelium, and the proportion is 2:2:1:1.

[0023] The specific steps of the preparation of the nutritional additives are as follows:

[0024] (1) Mix the volcanic rock with the mother liquor of threonine, put it in a calciner, and calcinate it at 580°C for 2 hours, take it out and pulverize it to get the volcanic rock mineral powder, mix it with the ...

Abstract

The invention discloses a nutrition additive for improving the salt tolerance of crops in seedling growing periods. The nutrition additive has the advantages that hyphae for the nutrition additive can adapt to salinity soil, P, Cu and Mg absorption of the crops can be improved when the nutrition additive is used in the seedling growing periods, Na and Cl absorption of the crops can be reduced, and accordingly the salt tolerance of the crops can be improved; weathered coal, cottonseed cake and the like are subjected to mixed fermentation, and accordingly a material basis can be provided for growth of the hyphae; the nutrition additive can be used as organic biomass, accordingly, the base exchange capacity of the soil can be improved, the fertilizer conservation capacity of the soil can be guaranteed at seedling stages, salinity of the soil can be improved, and effects of promoting growth of the crops can be realized.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a nutrient additive for seedling raising stage which improves the salt tolerance of crops 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...
