不同播种方式对直播水稻产量形成的影响
Effects of Different Seeding Methods on Yield Formation of Direct Seeding Rice
摘要
Abstract
To find out the influence of different seeding methods on rice yield formation of direct seeding rice,a field experiment of seeding method was carried out by using the rice precision hill⁃drop drilling machine to open seed furrow and water ditch.The hybrid rice variety Peizataifen and inbred rice variety Yuxiangyouzhan were used as materials,the effects of two kinds of seeding methods on rice dry matter accumulatioin dynamic and yield formation was studied.The results showed that under the condition of using the rice precision hill-drop drilling machine to open the seed furrow and water ditch,in the two seeding methods,the yield of manual drilling was higher than that of manual spotting,the yields of Peizataifeng and Yuxiangyouzhan were significant⁃ly increased by 23.77% and 10.89%,this increase was mainly from the increasing tiller number.Additionally, manual drilling was able to optimize rice population and increase the dry matter accumulation.In conclusion, under the condition of using the precision hill⁃drop drilling mechine to open seed furrow and water ditch,the manual drilling seeding method performed better than manual spotting in yield formation.关键词
