Rice seedling raising application of soluble ceramic fiber cotton and rice seedling raising method using soluble ceramic fiber cotton

Abstract

The invention discloses a rice seedling raising application of soluble ceramic fiber cotton and a rice seedling raising method using the soluble ceramic fiber cotton. The soluble ceramic fiber cotton is used as a seedling raising subsoil layer, a seed layer is arranged on the top surface of the soluble ceramic fiber cotton, a surface soil layer covers the seed layer, and the surface soil layer and the soluble ceramic fiber cotton are wetted by water. The rice seedling raising method comprises the following steps: laying the seed layer on the top surface of the soluble ceramic fiber cotton placed in a seedling raising tray, and covering the top surface of the seed layer with the surface soil layer; placing the seedling raising tray on a rice seedling bed with a plastic film spread for seedling raising; during the seed germination period of the seed layer, keeping the soluble ceramic fiber cotton moist; and transplanting the seedlings after seedling raising. According to the rice seedling raising application of the soluble ceramic fiber cotton and the rice seedling raising method using the soluble ceramic fiber cotton in the structure, enough water can be accumulated in the soluble ceramic fiber cotton, and packing of the seedlings in the seedling raising period is facilitated.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to an application of soluble ceramic fiber cotton for rice seedling raising and a method for raising rice seedlings. Background technique: [0002] Rice is an important grain widely planted in tropical Asia. Southern China is the main rice-producing area, and it is planted in all northern provinces. In order to improve the output of rice, rice is planted in the mode of transplanting after raising seedlings at present. Rice seedling raising in this process is one of the most critical steps in the whole rice cultivation. At present, in the seedling raising process of rice, it is generally by first laying a layer of subsoil in the seedling raising tray and watering and wetting, then laying a layer of seeds, and then laying a layer of soil and watering and wetting. However, due to the general water retention performance of the soil, it is difficult to control the water in the su...

AI Technical Summary

Problems solved by technology

However, due to the general water retention performance of the soil, it is difficult to control the water in the subsoil and surface soil during the whole seedling raising process; moreover, the soil requirements for the subsoil and surface soil used for seedling raising are relatively high, and the weight of the soil is relatively heavy. With the progress of urban construction, it is not only more and more difficult and labor-intensive to take soil, but also the process of taking soil and the turnover of soil after taking soil will have an impact on urban life, so the cost of taking soil and using it is also increasing. high

For this reason, soil is replaced by substrate in some places. Although the cost is reduced, due to the poor water retention of the substrate, it is easy to lack water in the seedling raising process, resulting in uneven emergence, rolled leaves and rotten roots, and serious damage rate of seedlings; The root system of the seedlings after matrix seedlings is underdeveloped and the packing is poor, resulting in serious planting injuries for machine-transplanted seedlings and slow rejuvenation of seedlings
