Simple warming and seedling-raising method for rice

Abstract

The invention belongs to the technical field of crop cultivation, and relates to a simple warming and seedling-raising method for rice. The method comprises: selecting varieties; treating seeds; preparing a simple greenhouse; sowing in good time, and timely performing ventilation and hardening seedlings; performing transplantation at a selected time, and managing rice fields well; performing early transplanting against time, and performing reasonable close planting; testing soil and formulating fertilization, and performing balanced fertilization; performing scientific irrigation and performing reasonable promotion and control; and harvesting rice in time. The method has the advantages of simple operation, high flexibility and low difficulty for operation, facilitates a single household to independently raise seedlings regardless of the rice transplanting area, allows early sowing, helps to prolong transplantation time, guarantees to increase the effective accumulated temperature at a seedling stage and prevents seedling rot at a low temperature, and has the advantages that transplantation with soil is realized, leaf change degree of seedlings is light, early growth and quick tillering of seedlings in a rice seedling bed are promoted, and cultivation of multi-tiller robust seedlings are facilitated, and the like.

Description

technical field [0001] The invention relates to a simple method for increasing temperature and raising seedlings of rice. Background technique [0002] In traditional rice seedling raising methods, there are generally two-stage seedling raising in greenhouses, film seedling raising, and dry seedling raising. However, the two sections of seedlings in the greenhouse need to be burned in the greenhouse for seedling cultivation. Due to the difference in the technical level of the people who burn the greenhouse, the plate adjustment is not timely, the water is not well controlled, and the temperature control is unscientific. , weak, or even burn out the entire greenhouse seedlings, affecting production, and the heating of the greenhouse requires a large amount of fuel, causing serious pollution. Under the conditions of dry-raised rice seedlings, the seedling field is overgrown with weeds and serious underground pests, so the acid must be adjusted regularly, otherwise the blight ...

Problems solved by technology

[0004] The purpose of the present invention is to propose a simple rice seedling raising method by increasing temperature, which can solve the problems of large amount of seeds used, concentrated labor, high technical requirements, small elasticity of seedling age, heavy rotten seedlings, low seedling survival rate, etc. in the current conventional seedling raising technology. Technical problems such as poor quality of seedlings, heavy clothes for transplanting in field, slow seedling emergence and tillering
