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): fly ash 23, sodium sulfate 3, lobster meal 24, beet pulp 25, tartaric acid 2, castor cake 18, diammonium phosphate 10, waste crop straw 60, threonine Mother liquor 15, aged tea leaves 24, compound fungal mycelium 5, volcanic rock 42, water in proper amount;

[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 calcine it at 680°C for 2.5 hours, take it out and pulverize it to get the volcanic rock mineral powder, mix it with the ground old tea leaves, and put it i...

Abstract

The invention discloses a nutritional additive used for increasing soil fertility and used in crop seedling period. The nutritional additive is prepared from following raw materials, by weight, 21 to 24 parts of fly ash, 3 to 4 parts of sodium sulfate, 22 to 25 parts of lobster powder, 24 to 26 parts of sugarbeet slag, 2 to 3 parts of tartaric acid, 16 to 20 parts of castor cake, 9 to 11 parts of diammonium phosphate, 58 to 64 parts of waste crop straw, 14 to 16 parts of threonine mother liquor, 22 to 26 parts of aged tea, 4 to 6 parts of composite fungal hyphae, 40 to 44 parts of volcanic rock, and an appropriate amount of water. The nutritional additive is different from common seedling fertilizers; soil aggregate structure is not destroyed by long term using, and accumulation of toxic matters is not caused by long term using; oppositely, adding of fungus and decomposed materials is capable of increasing beneficial microorganism and organic matter content of soil, realizing decomposition of inactive mineral nutrient composition in soil, reducing soil hardening, improving water and nutrient retention capacity in seedling period, improving soil productivity, and promoting growth of seedling crops.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a nutrient additive for raising soil fertility for crop seedlings 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 promote pla...
