Embodiment Construction

[0024] Example The agricultural promotion station of Huangping County Agriculture and Poverty Alleviation and Development Bureau adopted the method of the present invention to promote the direct seeding cultivation of rice. Select Qianyou 88, a high-yielding, high-quality variety with a moderate growth period, dwarf stalks, fertilizer resistance, lodging resistance, and strong rooting ability. Coat at a ratio of 3:1; prepare the field in advance in the leisure soaked winter field to achieve a flat surface, no exposed stubble, weeds, etc., shallow water without mud, and a deep and soft plow layer. Then it was sown from April 20th to 30th, and the sowing method was mechanical drilling; the granular fertilizer was mixed with paddy and sowed together.

[0025] Check the seedlings to make up for the gaps in time after the emergence of the seedlings. At the stage of 2 leaves and 1 heart (approximately 20-25 days after sowing), carry out dense and thinning and fill in the gaps to ens...

Abstract

The invention discloses a direct sowing culture method of rice. The direct sowing culture method comprises the steps: (1) selection of variety; (2) land preparation; (3) treatment of seed; (4) sowing; (5) management of emergence period; and (6) harvesting in time. The direct sowing culture method of the rice provided by the invention has the following advantages: (1) the working procedures are simple and convenient; human power is saved; and the effect is high; manpower can be saved by 45-70 persons per hour and square meter; the cost is saved by about 450 yuan per hour and square meter; and the labor productivity is raised by about 30%; (2) rice seedling raising and transplanting procedures can be reduced, thus mechanical sowing is convenient; (3) rice seedling bed is unnecessary, so that the planting area of grains and commercial crops can be expanded; and the cropping index can be improved; (4) root damage due to seedling pull-up and green turning process after transplanting can be avoided; the rice is tillered earlier, and the growth and development are faster; and (5) the cultivation characteristics of the direct sowing rice include developed root system, healthy and strong plant, strong disease resistance and large number of productive ear. The method is suitable for planting rice for villages.

Description

technical field [0001] The invention belongs to the planting of crops, in particular, relates to a method for planting rice. Background technique [0002] Paddy rice planting usually adopts the method of transplanting after raising seedlings first. This traditional method is time-consuming, labor-intensive, costly, and vulnerable to damage during transplanting of seedlings, which will reduce the tillering ability of rice and affect its yield and quality. People have started to study the direct-broadcasting technology of rice for this reason. Apparently, rice has few processes, labor-saving, high efficacy, and is convenient for mechanized sowing. At present, there is a Chinese patent application No. 200810046018.X "Paddy Direct Planting Method", which includes the steps of soil preparation, preparation of slag fertilizer, soaking seeds to accelerate germination, digging nests in dry fields, weeding, field fertilization, uniform seedlings, and pest control. . Although this...
