Cultivation method for reducing mechanical rolling and increasing yield of reclaimed rice

Abstract

The invention discloses a cultivation method for reducing mechanical rolling and improving the yield of direct seeding rice. The methods comprises the steps of (1) variety selection; (2) field preparation, wherein rotary tillage and stubble ploughing are conducted before seeding, weeds are turned and buried, and water is poured to soak a field before sowing; (3) disinfection and germination of rice seeds, wherein the seeds are sterilized with a quicklime clarification solution, the seeds are soaked in to break chests, and sprouted seeds in the seeds soaked are coated with dry raising nursing coatings in a granule form; (4) sowing; (5) fertilizer application, wherein a first season and a regenerative season are applied with a base fertilizer and topdressing, and the base fertilizer in the first season is a nitrogen, phosphorus and potassium compound fertilizer; (6) water management, wherein after sowing, from the emergence of seedlings in the first season to a three leaves and one heartperiod, from full heading to mature of natural dry, a drainage ditch is smooth, and drainage is conducted; (7) harvest in the first season; (8) weed prevention and removal, wherein a covering-filling-killing method is used, and from sowing to reviving, a tillering stage dressing is combined and mixed to be applied; (9) disease and pest prevention and control. The operation is simple, the rollingof rice piles by a machine is effectively reduced, the light transmittance and permeability of groups are improved, and the yield of the direct seeding retooning rice is improved.

Description

technical field [0001] The invention relates to the technical field of rice cultivation, and more specifically relates to a cultivation method for reducing the mechanical rolling of rice piles and increasing the yield of direct-seeding rice. Background technique [0002] The ratooning rice is a season of rice that is replanted and harvested using the axillary buds of the first season after the first season of rice harvest. It is one of the effective measures to improve the multiple cropping index, increase the rice yield per unit area of ​​paddy fields and economic income in areas where there is excess heat for one-crop rice and insufficient heat for double-crop rice. Compared with double-cropping rice cropping and paddy and dry crop rotation, ratooning rice has the advantages of saving water and fertilizer, high rice quality and high economic benefits, and has gradually developed into an important rice planting system in my country, with a harvested area of ​​730,000 hm 2 ...

AI Technical Summary

Problems solved by technology

[0004] Based on the existing defects in the cultivation of direct seeded ratooned rice, in order to solve the problem of poor light transmission and air permeability of the direct seeded rice group and the large area of ​​rice pile rolling caused by mechanical harvesting, the purpose of the present invention is to provide a method for reducing mechanical rolling. Cultivation method and method for improving the yield of direct-seeding rice
