Nutrition additive capable of improving mineral nutrition state at seedling raising stage and preparation method thereof

Abstract

The invention discloses a nutrition additive capable of improving a mineral nutrition state at a seedling raising stage. The nutrition additive capable of improving the mineral nutrition state at the seedling raising stage is prepared by using the following raw materials in parts by weight: 21-24 parts of plant ash, 19-21 parts of dry chicken manure, 5-6 parts of ferrous chloride, 1-2 parts of hydroxyethyl ethylenediamine triacetic acid, 8-10 parts of calcium ammonium nitrate, 24-26 parts of garden soil, 15-17 parts of edible acetic acid, 35-38 parts of volcanic rock, 65-75 parts of waste crop stalk, 4-6 parts of compound fungus hypha, 20-24 parts of threonine mother liquor, 18-22 parts of old tea leaf and a proper amount of water. The nutrition additive disclosed by the invention targets at crop seedlings, the mineral nutrition such as phosphorus, zinc and iron in soil can be dissolved and activated through reasonable raw material proportioning and preparation process, the absorption capacity is strong, the content of nutrition in the crop seedlings is improved, the mineral nutrition state of crops is improved, the growth of the seedlings is promoted and the field planting or grafting of the seedlings at a later stage is facilitated.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a nutritional additive for improving the mineral nutritional status in the seedling raising 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 ef...

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
