Seedling growing and machine transplanting method of double cropping rice

Abstract

The invention discloses a seedling growing and machine transplanting method of double cropping rice. The method comprises the following steps: early rice cultivation: making a seedbed on January to February, building a greenhouse, preparing a substrate, placing 20-25 hard seedling trays of (28*58*2.5) centimeters into each mu of field, sowing and performing seedling management; double cropping late rice cultivation: making a seedbed on April to May, preparing a substrate, placing 26-30 hard seedling trays of (28*58*2.5) centimeters into each mu of field, sowing and performing seedling management; machine transplanting and management of early rice; machine transplanting and management of double cropping late rice. According to the method, cured organic nutritional soil is taken as a substrate in seedling cultivation of early rice and late rice, so that sufficient nutritional components are provided for seedlings, and the environmental pollution is low; a sufficient amount of compound fertilizer is applied after machine transplanting of rice, a tiller fertilizer is applied and enclosed weeding is performed as early as possible, a jointing and flower promoting fertilizer is applied once again, prevention and control of banded sclerotial blight are performed, and harvesting is performed in time; specific to the difference in the seedling cultivation time of early rice and late rice, the fertilization and plant disease and insect pest prevention and control work of rice are performed, so that the maturing rate is increased.

Description

technical field [0001] The invention belongs to the technical field of rice cultivation, in particular to a machine-transplanting cultivation method for double-cropping rice seedling raising. Background technique [0002] Rice is one of the most important food crops in China and has an important strategic position in China's food production. The area of ​​rice in my country accounts for about 29% of the total area of ​​food crops, and the total output accounts for 44% of the country's total food production. More than 90% of it is concentrated In the southern rice-growing areas, double-cropping rice accounts for more than a quarter of the country's rice planting area, mainly concentrated in Jiangxi, Hunan, Guangdong, and Guangxi. [0003] Rice is also one of the crops that require the most fertilizer. Extensive fertilization increases the cost of crop production, pollutes the environment, and causes energy waste. The increase in rice yield and fertilizer utilization has an imp...

Problems solved by technology

[0003] Rice is also one of the crops that require the most fertilizer. Extensive fertilization increases the cost of crop production, pollutes the environment, and causes energy waste. The increase in rice yield and fertilizer utilization has an important relationship with topdressing. The fertilizer requirements of rice in different periods also vary. Different, fertilization at the seedling stage is crucial to the growth of rice

Most of the fertilizers in the rice seedling stage of the prior art can be purchased. This type of fertilizer has a single nutrient, and the application amount is relatively large, and it is easy to cause soil compaction, which is not good for the environment.
