A kind of formula and preparation method of watermelon nutrient soil cultivation matrix block

Abstract

The invention discloses a formula of watermelon nutrient soil cultivation matrix block, which comprises the following raw materials by weight: garden soil, bamboo charcoal powder, bone meal, rotten bark, animal manure, coconut shell powder, purified water, microbial fermentation agent, compound Fertilizer, mixed additive, extract additive and protease; a method for making watermelon nutrient soil cultivation substrate block, including S01: raw material pretreatment, S02: mixing and stirring, S03: microbial inoculation, S04: secondary mixing and S05: fermentation turning stir. In the present invention, the nutrient soil cultivation substrate block can effectively improve the water retention and permeability of the nutrient soil cultivation substrate block by adding a mixed additive composed of a water-retaining mixed solution and a permeability mixed solution, ensuring that nutrients can be stored in The uniform flow in the nutrient soil cultivation matrix block and the excessive loss of nutrients are avoided, so that the watermelon seedlings can be cultivated and grown quickly and healthily in the nutrient soil cultivation substrate block.

Description

technical field [0001] The invention relates to the technical field of seedling cultivation, in particular to a formula and a preparation method of a watermelon nutrient soil cultivation substrate block. Background technique [0002] Nutrient soil is specially formulated to meet the growth and development of seedlings and contains a variety of mineral nutrients. Nutrient soil is generally prepared by mixing fertile field soil and decomposed manure. Cultivation substrate refers to the soil environment around the crop has deteriorated, which has seriously affected the yield and quality of the crop. Cultivation medium, and in the process of watermelon seedling cultivation, it is also necessary to use nutrient soil cultivation substrate blocks to cultivate watermelon seedlings. [0003] However, in order to ensure the rapid flow of nutrients in the nutrient soil, the existing nutrient soil cultivation matrix blocks often make the nutrient soil cultivation matrix blocks relative...

AI Technical Summary

Problems solved by technology

[0003] However, in order to ensure the rapid flow of nutrients in the nutrient soil, the existing nutrient soil cultivation matrix blocks often make the nutrient soil cultivation matrix relatively loose, so that the water retention and permeability in the nutrient soil cultivation matrix block cannot achieve a good dynamic balance. , which in turn leads to excessive loss of nutrient elements and reduces the cultivation quality of watermelon seedlings
