Salt-resistant high-yield new variety rice seedling cultivation method

Abstract

The invention relates to the technical field of rice seedling cultivation, and discloses a salt-tolerant high-yield new variety rice seedling cultivation method which comprises the following steps: S1, seed selection; s2, seedling culture: (1) preparation of seedling culture nutrient soil; (2) seed treatment and sowing rate determination; (3) sowing: putting the prepared seedling culture nutrient soil on a seedling culture tray, sowing seeds on the seedling culture tray, and putting the seedling culture tray into a greenhouse; (4) seedling management. According to the salt-tolerant high-yield new variety rice seedling cultivation method, rice seeds with high salt tolerance are selected through screening of the rice seeds, late-maturing high-yield varieties can be cultivated through a temperature control breeding method, the purposes of salt tolerance and high yield of the rice are achieved, then the rice seedlings are planted in a seedling tray in an ordered arrangement mode, the rice seedlings can be observed and measured more conveniently, and the rice seedling cultivation efficiency is improved. Meanwhile, the salt-tolerant rice seeds can be rapidly selected through seed selection in a seedling height difference mode, and therefore the effects that the salt-tolerant high-yield rice seedlings can be cultivated, and the cultivation efficiency is high are achieved.

Description

technical field [0001] The invention relates to the technical field of rice seedling cultivation, in particular to a method for cultivating rice seedlings of a new salt-tolerant and high-yield variety. Background technique [0002] Rice is a cereal crop belonging to the genus Oryza, and the representative species is rice. Rice is native to China and India. The ancestors of the Yangtze River in China planted rice seven thousand years ago. Rice is divided into indica rice and japonica rice, early rice and middle-late rice, glutinous rice and non-glutinous rice according to the type of rice. conventional rice and hybrid rice. [0003] Most of the existing high-tech genetically modified rice can change the quality and characters of rice, but it cannot increase the yield of crops, and because the price of genetically modified seeds is much higher than that of ordinary good seeds, it increases the cost of agricultural planting, and rice is being mechanized. A seedling tray needs...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing high-tech transgenes that rely on can change the quality and traits of rice, but they cannot increase the yield of crops, and because the price of transgenic seeds is much higher than that of ordinary seeds, it increases the cost of agricultural planting. At the same time, rice is mechanized. Seedling trays are needed in the process of planting and cultivation. The existing seedling trays have a simple structure and cannot arrange the seedlings in an orderly manner, resulting in poor cultivation and planting effects.
