Rice seedling substrate and preparation method thereof

Abstract

The invention provides a rice seedling substrate and a preparation method thereof. The rice seedling substrate is prepared from components in percentage by weight as follows: 25%-45% of leaf mold, 15%-25% of mushroom residue, 10%-20% of peanut shell powder, 10%-20% of perlite, 1%-10% of plant ash, 5%-15% of chicken manure and 1%-5% of urea. With adoption of the rice seedling substrate, seedlings emerge quickly and neatly, pest and disease damage less occurs, disease prevention and weeding are not needed in the whole seedling culture stage, only watering is needed, the operation is convenient,time and labor are saved, seedling quality is high, the stress resistance is higher, diseases such as damping-off, bacterial wilt and the like are avoided in the seedling stage, the seedlings are short and stout, and leaves are wide and brilliant green in color.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a rice seedling raising substrate and a preparation method thereof. Background technique [0002] Rice seedling cultivation in my country still follows the traditional way of raising seedlings with soil. This method has the following disadvantages: First, the traditional soil seedling cultivation process is complicated, labor-intensive, high cost of seedling cultivation, low technical content, and difficult to manage. Only the preparation of nutrient soil includes many processes such as taking soil, drying soil, crushing, sieving soil, mixing fertilizer, mixing medicine, adjusting acid, weeding, and preventing diseases. ), the labor intensity of transporting seedlings in the field is high, but the rice seedling raising substrate of the present invention has only about 4 jin of seedlings per plate, and the seedling transporting intensity is greatly red...

AI Technical Summary

Problems solved by technology

This method has the following disadvantages: First, the traditional soil seedling breeding process is complicated, labor-intensive, high seedling cost, low technical content, and difficult to manage

Second, it is difficult to guarantee the quality of seedlings raised in traditional soil

Due to the serious soil-borne diseases of soil seedlings, the requirements for sowing management are high; in case of low temperature in spring, physiological diseases often occur, the quality of seedlings is poor, and it is difficult to grow high-quality robust seedlings; It is very difficult; the success rate of seedling cultivation is low, which is not conducive to factory and standardized seedling cultivation

Third, it is difficult for farmers to raise seedlings and obtain soil

Some farmers go to various places to buy soil; they even dig out the ridges of the paddy fields that they have worked so hard to use as soil for rice seedlings.

Fourth, there has been a serious conflict between raising seedlings and taking soil and protecting the ecological environment

In recent years, people have been exploring and reforming the traditional soil seedling raising methods, and some rice seedling raising substrates have been newly invented, mainly using crop straw fermentation, rice husk fermentation, waste edible fungus bag fermentation, perlite, pulp mixture, and perlite + leech The mixture of stone + peat as raw materials has restricted the progress of new substrates and new technologies for seedlings due to complex production processes, inconvenient transportation of raw materials, high production costs, difficult operations, limited resources, and unsatisfactory seedling effects. Difficult to popularize and apply in a large area, and difficult to innovate and make substantial technical breakthroughs in traditional soil seedling cultivation methods
