Organic ecological substrate for rice industrialized seedling production and preparation method of organic ecological substrate

Abstract

The invention belongs to the technical field of rice matrix seedling and discloses an organic ecological substrate for rice industrialized seedling production. The organic ecological substrate for rice industrialized seedling production comprises the following components in parts by mass: 20 to 40 parts of animal dung, 30 to 50 parts of organic waste, 15 to 30 parts of a conditioner, 20 to 40 parts of carbonized rice husk and 0.01 to 0.03 part of a microbial agent. The organic ecological substrate has high nutrient content and good seedling strengthening effect. The invention also provides a preparation method of the organic ecological substrate for rice industrialized seedling production.

Description

technical field [0001] The invention relates to the technical field of rice matrix seedling cultivation. Background technique [0002] Substrate seedling cultivation is a kind of soilless seedling cultivation, which means that soil is not added when configuring the nutrients for seedling cultivation, but is replaced by substrates such as peat, vermiculite, perlite, sawdust, slag, rice husk, peanut shell, and corn orange. The way of raising seedlings in soil. The matrix is ​​divided into organic matrix and inorganic matrix according to the different components. Because the inorganic matrix contains less nutrients and has poor water retention capacity, it must be regularly watered with suitable nutrient solution to supplement nutrients and water when using it. The organic matrix contains nutrients. There are many ingredients, and the ability to retain water and fertilizer is strong. No nutrient solution or only a small amount of nutrient solution can be poured, but its permea...

AI Technical Summary

Problems solved by technology

The fertilization and preparation of the existing nutrient soil often fail to meet the requirements of strong seedlings, and the nutritional content is low, which can easily lead to malnutrition in the middle stage of seedling cultivation, poor growth of seedlings, insufficient uniformity of seedlings, and prone to problems such as plant diseases and insect pests.

Moreover, although the cost of raising seedlings with nutrient soil is low, there are a series of problems such as high labor intensity, many labors for seedling raising and raising seedlings, complicated procedures, occupation of cultivated land, heavy seedlings, heavy mechanical work load and loss.
