Seedling breeding method using mechanical inserting of nonwoven cloth for rice

Abstract

The invention discloses a seedling breeding method using mechanical inserting of a nonwoven cloth for rice, and belongs to the technical field of early rice seedling breeding, which mainly aims at solving the problem of seedling breeding by plastic thin films. The method comprises the following steps of selecting the nonwoven cloth with proper size to cover, selecting low temperature-resistant early rice variety, building a square arch greenhouse, and performing early rice seedling breeding at extreme low temperature in a microfilm and nonwoven cloth mode. The method has the advantages that by using the square arch greenhouse and the nonwoven cloth to cover, the temperature in a seedling breeding bed is slowly changed, the relative humidity is low, the growth of seedling is stable and strong, and the disease-resistant capability is improved; the watering frequency is reduced, the nonwoven cloth is not removed away during watering, the water is directly watered on the nonwoven cloth, the film removal for air ventilation is not needed, the complicated working of high-temperature removal of agricultural film is avoided, the early planting in sunny days as much as possible is favorably performed, and the defect of breed seedling using plastic thin film to cover is overcome.

Description

technical field [0001] The invention relates to the technical field of seedling raising of early rice, in particular to a seedling raising method of rice machine-transplanted with non-woven fabric. Background technique [0002] Early rice seedling raising is an important part of early rice production. In recent years, the abnormal climate during early rice seedling raising, especially high temperature and cold spring has a serious impact on early rice seedling raising, the seedling rate is low, and the quality of seedlings is poor. It is imminent to innovate the method of early rice seedling raising. Since the 1970s, early rice seedlings have been covered with plastic films. This method has good thermal insulation performance, but the seedlings are prone to excessive growth, dew condensation in the plastic film, and the seedlings are prone to blight and bacterial wilt, and even high-temperature burning. During the high temperature period, it is necessary to ventilate and ha...
