Rice seedling cultivation method

Abstract

The invention discloses a rice seedling cultivation method. The rice seedling cultivation method mainly comprises the following steps: selecting full rice seeds without plant diseases and insect pestsand capable of growing into strong plants, performing pretreatment, and putting into a seedling cultivation disk containing plant ash, peat, fine sand and humus to perform seedling cultivation; and performing reasonable seedling cultivation management, performing germination and transplanting. Compared with the prior art, the seedling cultivation method has the following advantages: a mixed substrate of the plant ash, the peat, the fine sand and the humus is adopted, the nutritional proportion is sufficient and reasonable, the cultivated seedlings grow strongly and tidily and the root systemis developed; meanwhile, through reasonable seedling cultivation management, the characteristics of high germination rate, short cultivation time, capability of reducing plant disease and insect pestrate and the like are achieved, seedlings are recovered rapidly after field planting, and the survival rate is up to above 95 percent.

Description

technical field [0001] The invention relates to a rice seedling raising method, which belongs to the technical field of agricultural planting. Background technique [0002] Rice is a direct economic crop widely planted in my country. Rice can be divided into indica rice and japonica rice, early rice and mid-late rice, glutinous rice and non-glutinous rice. Soilless seedling cultivation of rice has a history of more than ten years, and it is more representative in northern China. There are rock wool, rice husk, and vitrified microbead seedling raising techniques, but at present, the survival rate of rice seedlings cannot be improved as much as possible, the yield is small, and the cultivation method is improper; in the annual sowing season, there are always a few During the process of seed soaking and accelerating germination, the quality of the seedlings is poor, the seedlings do not grow, the roots are not packed, and the rice seedlings cannot be transplanted in some places, ...

[0002] Rice is a direct economic crop widely planted in my country. Rice can be divided into indica rice and japonica rice, early rice and mid-late rice, glutinous rice and non-glutinous rice. Soilless seedling cultivation of rice has a history of more than ten years, and it is more representative in northern China. There are rock wool, rice husk, and vitrified microbead seedling raising techniques, but at present, the survival rate of rice seedlings cannot be improved as much as possible, the yield is small, and the cultivation method is improper; in the annual sowing season, there are always a few During the process of seed soaking and accelerating germination, the quality of the seedlings is poor, the seedlings do not grow, the roots are not packed, and the rice seedlings cannot be transplanted in some places, and the phenomenon of dead seedlings often occurs, resulting in a significant reduction in the output of rice, which affects the normal income of farmers; therefore, the invention A new kind of rice seedling raising method has become a problem that people need to solve
