A container seedling culture substrate suitable for citrus growth and its preparation method

Abstract

A container seedling cultivation substrate suitable for citrus growth is composed of sludge and river sand, and the sludge is one or more of water supply sludge, industrial wastewater sludge and domestic sewage sludge. The container seedling raising substrate of the present invention uses sewage sludge as raw material, can utilize sewage sludge waste, solves the problem of difficult disposal of sludge, can also reduce the use of traditional substrate raw material peat, reduce costs, and reasonably protect non-renewable resources The raw material cost of the present invention is lower simultaneously, and the survival rate of the citrus seedlings that utilizes this organic seedling-growing substrate to cultivate is as high as 100%; Efficient effect, one-time fertilization, no need to add fertilizer multiple times in the growth process of seedlings, reduce costs and reduce operations at the same time, the citrus seedlings cultivated with the substrate of the present invention have good growth, neat emergence rate, and low cost, which is worth popularizing a new technology.

Description

technical field [0001] The invention mainly relates to the field of cultivation technology, in particular to a container seedling cultivation substrate suitable for growing citrus seedlings and a preparation method thereof. Background technique [0002] Cultivating containers with disease-free taproots and strong seedlings is the foundation of the tree body. Citrus container seedlings are equipped with suitable formula substrates and can produce high-quality seedlings. In recent years, they have been widely used in citrus container seedlings across the country. The nutrient soil formula for citrus container cultivation is usually chaff: river sand: peat = 1:1:2 (volume ratio), and the process of citrus container cultivation requires a lot of peat. The use of a large amount of peat is a waste of resources, and it increases the cost of citrus container seedlings, and also restricts the development of citrus seedlings. It is uneconomical to rely on commercial substrates such as...

AI Technical Summary

Problems solved by technology

The use of a large amount of peat is a waste of resources, and it increases the cost of citrus container seedlings, and also restricts the development of citrus seedlings. It is uneconomical to rely on commercial substrates such as peat, and it is difficult to promote on a large scale. Local cheap and easily available resources are used according to local conditions. , and gradually reducing the use of peat is one of the healthy and sustainable development directions of the container seedling industry
