Sowing accelerating method for rapid sprouting and once-sowing full stand of direct-seeding rice

Abstract

The invention discloses a sowing accelerating method for rapid sprouting and once-sowing full stand of direct-seeding rice and belongs to the technical field of crop cultivation. The sowing accelerating method comprises five steps of sunning seeds, immersing the seeds, accelerating germination, airing and sowing the seeds, and covering the seeds after sowing. According to the sowing accelerating method, by implementing germination accelerating breaking and exposing sowing and the step of covering the seeds after sowing in a matched manner, the emergence rate is guaranteed; the problems in the prior art that the seeds are usually suffocated, caused by the fact in the conventional direct seeding that after rice grains are sowed, water is irrigated to moisten soil and then weeds are removed in a closed manner, so that the emergence rate is influenced are solved. The sowing accelerating method also has the other characteristic that dry bud reaccelerated seeds sprout, and the seeds are activated as soon as the seeds are moistened by the water, so that the aim of once-sowing full stand is realized; the seeds can sprout 3-4 days ahead due to the dry bud reacceleration. The accelerated rice also has the advantages of strong seasonality and strong drought resistance capability and lodging-resistance capability.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and more specifically relates to a method for accelerating the sowing of dry direct-seeding rice for rapid emergence and sowing of whole seedlings. Background technique [0002] Dry direct seeding of rice is a new type of high-efficiency, labor-saving, water-saving and easy-to-mechanize cultivation technology. It is also one of the preferred technologies for stabilizing the area and increasing the yield during the transition period of the current rice production technology. As a new high-efficiency water-saving cultivation technology, dry direct seeding of rice plays an irreplaceable role in stabilizing the rice planting area, and has broad development prospects in our country. However, in large-scale production, the low seedling rate and irregular emergence are the limiting factors for high and stable yield of dry-directed rice, which has also become the key restrictive factor for the l...

Problems solved by technology

[0005] Aiming at the above-mentioned problems existing in the prior art, the present invention provides a method for accelerating the sowing of dry direct-seeding rice seedlings to quickly emerge and sow the whole seedlings. It is implemented in conjunction with covering the seeds after sowing to ensure the emergence rate; and it solves the problem in the prior art that the conventional dry direct seeding is sowed by dumb valleys and then filled with water and moistened soil and then closed for weeding, which often leads to seed burrows and affects the emergence rate. Another feature of the method is that the dry bud re-catalyzed seeds have germinated, and when the seeds are wetted by water, they are activated immediately to achieve the purpose of sowing all seedlings; and the present invention can advance the emergence of seedlings 3-4 days due to the dry bud re-catalyze
