Gardening culture medium and preparation method thereof

Abstract

According to the gardening culture medium and the preparation method thereof, the production process is advanced, firstly, a loam soil matrix is exposed to the sun for sterilization, it is avoided that beneficial bacteria in the loam soil matrix are killed through high-temperature sterilization and drug sterilization, and seedlings can absorb nutrients in soil more easily; by adopting a soaking method, rice hulls and wood chips are soaked in corresponding liquid chemical fertilizers, and then the rice hulls and the wood chips are mixed with a loam soil matrix, so that the lasting time of the fertilizers in the loam soil matrix can be prolonged, meanwhile, the problem that the fertilizers are easy to lose is avoided, and the use of the wood chips is reduced; different liquid chemical fertilizer formulas can be selected according to different cultivated seedlings, and the problem that the requirements of different seedlings cannot be met due to the fact that nutrient components of a cultivation medium produced through a traditional method are consistent is solved; the soft straws and the rice hulls are added, so that the loam soil matrix is not too loose and is not hardened or caked, root development and transplanting of seedlings are facilitated, and the practicability is higher.

Description

technical field [0001] The invention belongs to the technical field of seedling cultivation, and in particular relates to a horticultural cultivation substrate and a preparation method thereof. Background technique [0002] Seedling is the cultivation of plant seedlings, and the method of raising seedlings is a cultivation method of cultivating seedlings in specially set seedbeds for transplanting in production fields. Rice, sweet potatoes, vegetables, fruit trees and flowers and other crops mostly use the seedling method. According to different sites and facilities, it can be divided into protected field seedling raising method, open field seedling raising method, factory seedling raising method, soilless seedling raising method, cutting seedling raising method, nutrition pot raising seedling method and so on. Compared with the direct seeding method, the advantage of this method is that it creates the required environmental conditions according to the characteristics of cr...

AI Technical Summary

Problems solved by technology

[0004] In addition to temperature and light, the key to seedling cultivation lies in the selection of cultivation substrates. However, there are still some unreasonable factors in the current cultivation substrates for garden seedling cultivation in the process of cultivating seedlings. Time: The nutrients in the matrix are lost quickly, and there is no good storage of nutrients, so that the seedlings need to be supplemented with nutrient solution regularly before the cultivation period is over, which requires a lot of manpower and material resources; at the same time, the composition of the matrix is ​​not enough Reasonable, filling more sawdust rotting leaves makes the soil too loose to retain water; while less sawdust rot leaves, the soil matrix is ​​easy to agglomerate and harden, which is not conducive to the root growth and transplanting of seedlings, and the practicability is poor
