摘要:

为探索不同直播方式对水稻生产的影响,筛选出科学高效的播种方式,以秀水14为试验品种,特开展3种不同水稻直播方式对比试验。结果表明,不同直播方式水稻总叶龄、结实率无明显差异,其中穴直播方式下水稻叶龄和分蘖数增长相对较慢,有效穗数相对偏低,但穗粒数多、千粒重大,实际产量达9 037.5 kg·hm-2,分别比喷直播和飞播高7.8%、3.1%;穴直播方式效益最高,达4 847.3元·hm-2,分别比喷直播和飞播高60.8%、15.0%,是目前桐乡地区最理想的水稻直播方式。

Abstract:

In order to explore the influence of different direct seeding methods on rice production and screen out scientific and efficient sowing methods, a comparative test of three different rice direct seeding methods was carried out with Xiushui 14 as the experimental variety. The results showed that there was no significant difference in the total leaf age and seed setting rate of rice under different direct seeding methods. For hole direct seeding, the growth of leaf age and tiller number was relatively slower, and the effective spike number was relatively lower, but the actual yield reached 9 037.5 kg·hm-2, which was 7.8% and 3.1% higher than that of spray direct seeding and aerial seeding, respectively. The benefit of hole direct seeding method was the highest, reaching 4 847.3 yuan·hm-2, which was 60.8% and 15.0% higher than that of spray direct seeding and aerial seeding, respectively. It is currently the most ideal way of rice direct broadcast in Tongxiang Area.

Key words: rice, direct seeding, yield, benefit
