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): Coal slime 25, Hull chaff ash 23, Nitrilotriacetic acid 1, Sodium nitrate 12, Sawdust 17, Chicken feather 18, Calcium fulvic acid 7, Volcanic rock 38, Threonine mother liquor 19. Old tea leaves 24. Waste crop straw 75. Composite fungal hyphae 4. 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 610°C for 1.5 hours, take it out and pulverize it to get the volcanic rock mineral powder, mix it with the ground old tea l...

Abstract

The invention discloses a seedling-stage nutritional addition material stable in fertilizer efficiency and long in action period. The seedling-stage nutritional addition material is prepared from, by weight, 23 to 27 parts of coal slime, 22 to 24 parts of rice chaff ash, 1 to 2 parts of nitrilotriacetic acid, 10 to 14 parts of sodium nitrate, 16 to 18 parts of sawdust, 17 to 19 parts of chicken feather, 6 to 8 parts of fulvic acid calcium, 36 to 40 parts of volcanic rock, 18 to 20 parts of threonine mother liquor, 21 to 25 parts of aged tea, 72 to 78 parts of waste crop straw, 4 to 5 parts of composite fungal hyphae, and an appropriate amount of water. According to a preparation method, the seedling-stage nutritional addition material is prepared from common raw materials such as coal slime and waste chicken feather via a plurality of steps such as fermentation, chelation, and pelletizing, and is capable of improving soil physicochemical properties and nutritional characteristics; a large amount of fungus is added, so that the seedling-stage nutritional addition material is capable of providing seedlings with required nutrients, relatively stable complementary nutritional system among the bacteria is formed; dominant bacterial communities are formed; and activity of the seedling-stage nutritional addition material can be maintained for a relatively long time, and fertilizer efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a nutrient additive for seedling stage with a long period of stable fertilizer effect 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...
