Rice husk matrix board for soil-less seedling raising of rice and preparation method

Abstract

The invention relates to a rice husk matrix board for soil-less seedling raising of rice. The matrix board is made of corn straw, fine grass carbon soil, coconut shell powder, paper and rice husks after puffing treatment. The invention further provides a preparation method of the matrix board. The rice husk matrix board replaces seedling raising soil, and rice seedlings which are high in seedlingformation rate and better in comprehensive quality can be cultured; the soil, labor and cost are saved, mechanical transplanting of rice seedlings is evener, the missing rate of the rice seedlings isreduced, mechanically transplanted seedlings are even and consistent, and the formation of a group with high photosynthetic efficiency is facilitated; moreover, the mechanically transplanted seedlingsturn green quickly and root and tiller early, and the high yield and high efficiency can be achieved in the process of mechanical transplanting. The rice husk matrix board is also more suitable for mechanized rapid operation methods and large-area popularization application.

Description

Technical field [0001] The present invention relates to the technical field of rice seedling cultivation without soil, in particular to a rice husk substrate board for soilless rice seedling cultivation, and also to a preparation method of the rice husk substrate board. Background technique [0002] Rice is one of the main crops in my country’s agricultural production. Its planting technology, yield per acre, and economic benefits have now been significantly improved, which has played an important role in ensuring my country’s food security; but the technology and benefits of rice There is room for further improvement, especially the seedling raising technology in the rice planting process. As the saying goes, "the seedlings are good for half a year," and cultivating high-quality seedlings is essential to increase the yield and quality of rice. [0003] At present, the popular machine-transplanted dry seedlings, in the process of raising seedlings, it is necessary to collect loam t...

AI Technical Summary

Problems solved by technology

[0004] Moreover, farmers have to carry out cumbersome operations such as taking soil, crushing, sieving, storing, mixing soil and fertilizer, and manually arranging plates every year, wasting a lot of manpower and material resources

Especially in the rice planting areas in northern my country, there are still problems such as short growth period, less active accumulated temperature, slow growth in the early stage of growth, short high temperature time in the middle stage, rapid cooling in the later stage, and many low temperature and chilling injuries.
