Effects of different direct seeding methods on rice yield and economic benefits
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.
