早籼稻不同直播方式比较试验

Comparison of Different Direct Seeding Methods of Early Indica Rice

为了探明不同直播方式对水稻生长和产量的影响,筛选出适宜瑞安市的先进、适用早稻直播栽培技术,以常规早籼稻甬籼15为试验材料,对喷粉机直播、精量穴直播、无人机直播和人工直播等4种不同直播方式进行对比试验。结果表明,不同直播方式对早籼稻的出苗数、有效穗数和产量有一定的影响,播种效率、作业成本和机具利用率也不同。本研究可为不同种植主体选用不同的直播方式提供参考。

In order to explore the effects of different direct seeding methods on rice growth and yield,advanced and suitable early rice direct seeding cultivation techniques were screened out.Taking conventional early indica rice Yongxian 15 as the test material,four different direct seeding methods,including powder spraying machine direct seeding,precision hole direct seeding,UAV direct seeding and manual direct seeding,were tested and compared.The results showed that different direct seeding methods had certain effects on the seedling emergence,effective panicle number and yield of early indica rice,and the sowing efficiency,operating cost and the utilization rate of machines and tools were also different.The research provides a reference for different planting subjects to choose different direct seeding methods.
