Dryland direct sowing cultivation technique for rice

Abstract

The invention provides a dryland direct sowing cultivation technique for rice. The technique comprises the steps of soil preparation, seed selection, seed treatment, sowing, weeding, resowing, plant supplement and irrigation, fertilization, inset prevention, and the like. During the cultivation process, through optimization of an excellent suitable variety, a reasonable and scientific farmland management plan, and weeding techniques, the dryland direct sowing technique for the rice can be realized directly; besides, the dryland direct sowing cultivation technique has obvious advantages in yield, weeding, and the like, and solves the problems that a great mount of manpower needs to be consumed in rice transplant techniques in the prior art and a number of farmland is not suitable for water direct seeding.

Description

technical field [0001] The invention relates to a dry direct seeding cultivation technique of rice. Background technique [0002] Direct seeding of rice is a cultivation method that directly sows seeds in the field without raising seedlings and transplanting. Rice live broadcast has the following advantages: First, it saves labor and effort. Direct direct seeding eliminates traditional seedling raising and transplanting labor, and saves seedling fields, making rice production simple and easy; second, high yield; because direct direct seeding rice is more conducive to low-node tillering, the panicle stem is optimized and rationally allocated, and the main tiller ears are basically uniform. The panicle rate is high, the total number of panicles is large, and the direct-seeding rice in large-scale production generally increases the yield by 5% compared with the traditional transplanted rice; the third is that the growth period is shortened. Direct-directed rice has no seedlin...
