Method for reducing loss and increasing yield of machine-harvested ratoon rice

Abstract

The invention discloses a method for reducing loss and increasing yield of machine-harvested ratoon rice, which aims to solve the technical problem that in the current mechanical harvesting of ratoonrice, the roller compaction degree of a rice pile is large, and thus axillary buds on the rice pile reserved for the first season rice are easy to be damaged or even killed, so that the yield of the ratoon rice in the ratoon season is greatly reduced. According to the method, in the harvesting of the first season rice, crawlers with a certain size and a harvester with a cut width are used for harvesting rice plants, the wide row spacing between the rice plants is utilized, so that two rows of crawlers respectively travel in the gaps between the wide row rice plants when the harvester works, and the crawlers are harvested and walked along the long direction along with the row of the rice plants, and the ends of two narrower ends of the planting field are used as fixing turn-around turning areas of the harvester, so that the movement of the harvester finally forms an 'III'-shaped walking track from outside to inside. The method reduces the roller compaction degree and area proportion ofrice piles, enhances the sprouting ability of the axillary buds of the rice piles, improves the germination unification degree of the axillary buds of the rice plants, improves the maturity consistency of the rice spikes in the regeneration season, and realizes the effects of reducing the yield and improving the quality.

Description

technical field [0001] The invention belongs to the technical field of ratooning rice cultivation and agronomy, in particular to a method for reducing damage and increasing yield of ratooned rice by machine harvesting. Background technique [0002] Raisoning rice is a kind of rice farming mode that utilizes the rice piles after rice harvesting, and through scientific field fertilizer and water management, makes the dormant axillary buds on the rice piles quickly germinate into seedlings, head and firm and harvest again; that is, after the first season rice is harvested, use The rice stumps re-germinate, grow into seedlings, and grow into ears, and then harvest the second batch of rice. Its characteristic is that after the first season of rice matures, only about 2 / 3 of the upper part of the rice plant is cut off, and the rice ears are collected, and the middle and lower 1 / 3 of the plant and root system are left for fertilization and management to allow it to grow a second cr...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a method for reducing the damage and increasing the yield of ratooned rice by machine, which aims to solve the problem of the large degree of crushing of rice piles in the mechanical harvesting of ratooned rice, which easily leads to the retention of the first season rice. The axillary buds on the rice piles were damaged or even died, which greatly reduced the technical problem of the regeneration season yield of ratooned rice; this method significantly reduced the proportion of the rice piles that were crushed when the first season of rice was harvested, and at the same time reduced the degree of pressure on the rice piles. Enhance the germination ability of rice stump axillary buds, improve the uniformity of rice plant axillary bud germination, improve the maturity consistency of rice spikes in the regeneration season, and achieve the effect of reducing damage, increasing yield and improving quality
