摘要
[目的]研究水稻直播中的几个关键技术,为水稻直播的大面积推广应用提供科学的理论指导.[方法]在绵阳市安州区进行水稻直播技术研究,经过2013-2016年连续4年的试验,筛选出了适合水稻直播的品种、确定了辐优838直播的最佳播种量和多效唑喷施期.[结果]在供试的10个品种中,产量居前的是辐优838、F优498、川作优619、内5优979;从综合指标来看,这4个品种更适合直播.通过水稻的自我调节能力,辐优838播种量在22.5 ～ 33.8 kg/hm2范围内有利于高产.直播水稻辐优838在2叶期喷施多效唑可显著增产.[结论]田间小区试验显示水稻直播技术可以达到增产稳产的效果.
Abstract
[Objective] To research several key technologies of rice direct seeding,and to provide scientific and theoretical direction for the widespread popularization and application of rice direct seeding.[Method] Rice direct seeding in Anzhou District of Mianyang City was researched.Through four years test from 2013 to 2016,we screened the proper cultivar for rice direct seeding,and found the optimal seeding quantity and paclobutrazol spraying period of Fuyou 838.[Result] Among the 10 tested cultivars,Fuyou 838,F you 498,Chuanzuoyou 619 and Nei 5 you 979 had relatively high yield.According to the comprehensive index,these four cultivars were relatively more suitable for direct seeding.The 22.5-33.8 kg/hm2 seeding quantity of Fuyou 838 was helpful to enhance the yield by rice self-regulation.And spraying paclobutrazol at two-leaves period could significantly enhance the yield of Fuyou 838.[Conclusion] Field test shows that rice direct seeding can increase and stabilize the yield.
