Rice transplanting and seedling raising substrate for rice machine

Abstract

The invention discloses a rice transplanting and seedling raising substrate for a rice machine. The rice transplanting and seedling raising substrate comprises the following raw materials in parts by weight: 20-100 parts of crop processing residues or wastes and 0-80 parts of crop straw crushing particles. A preparation method of the rice transplanting and seedling raising substrate comprises the steps of: uniformly mixing the raw materials; adding water until the raw materials form a lump through pinching by hands and are scattered after falling on the ground; then stacking; covering by using an agricultural film for sheltering from rain and raising temperature; naturally fermenting for 10-20d; and accelerating full ripening of the substrate to obtain a product of the rice transplanting and seedling raising substrate. The rice transplanting and seedling raising substrate for the rice machine, provided by the invention, has the advantages of low production cost and good rice seedling raising effect, and the raw materials are easily obtained in the South.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a rice machine-transplanted seedling-raising substrate. Background technique [0002] In my country, when it is difficult to expand the planting area of ​​rice and ensure the steady growth of the total output, it is necessary to adopt improved varieties and technical measures to increase the output. Among them, the mechanized technology of rice seedling raising and transplanting is one of the agricultural technologies promoted by the Ministry of Agriculture of the People's Republic of China. important means of production. With the large-scale promotion of rice machine transplanting technology, the problems affecting and restricting the development of rice machine transplanting have become increasingly prominent. First, it is difficult to obtain soil and destroy vegetation in the process of machine transplanting and raising seedlings. The development of industrial seedling r...

AI Technical Summary

Problems solved by technology

The development of industrial seedling raising requires a large amount of bed soil (4m3 of high-quality humus soil or dry field soil per hectare, which is equivalent to the removal of 100,000 mu of dry field topsoil), and a large number of high-quality topsoil from fields and mountains must be excavated every year. Seriously damage the cultivation surface and vegetation, affecting the development of machine-transplanted rice

Second, the quality of the seedlings is not stable, and the nutrient content of the seedling bed soil and the unevenness of the fertilizer make it difficult to strengthen the seedlings, which is not conducive to the high and stable yield of machine-transplanted rice.

[0003] At present, the substrate for machine-transplanted rice seedlings promoted on a large scale—the Huaiyin chaimihe substrate, the main raw materials are peat mud, vermiculite, perlite, etc.
