不同栽培方式对水稻农艺性状·产量及效益的影响

Effects of Different Cultivation Methods on the Yield,Agronomic Trait and Economic Benefit of Rice

[目的]探寻低成本、优质、高效的水稻栽培方式,简化水稻生产过程中的程序,减轻劳动强度,提高经济效益。[方法]以"武育粳3号"为试验材料,通过田间小区试验,研究不同栽培方式对水稻农艺性状、产量结构及经济效益的影响。[结果]免耕抛秧、免耕直播是较好的栽培方式,与其他栽培方式相比,产量及效益差异均达到极显著水平。[结论]该研究可为水稻免耕技术、机械化和直播大面积推广应用提供科学的理论指导。

[Objective] To discuss the rice cultivation method with low cost,high quality and high efficiency,to simplify the procedure of rice production,and to reduce the labor intensity and enhance the economic benefit.[Method] With Wuyujing 3 as the test material,filed plot test was carried out to research the effects of cultivation method on the yield,agronomic trait and economic benefit of rice.[Result] No-tillage and cast transplanting,no-tillage and direct seeding were relatively good cultivation methods.Compared with other cultivation modes,yield and benefit differences both reached extremely significant level.[Conclusion]This research provides scientific theoretical guidance for the large-scale extension of no-tillage technology,mechanization and direct sowing of rice.
