摘要
为探究不同栽培方式对水稻群体结构和产量的影响,以湖南省常德市汉寿县为试验地点,设置人工直播、机械插秧、人工抛秧和飞机直播4种栽培方式进行试验,比较不同栽培方式下水稻的生长状况、产量和经济指标.结果显示,人工直播方式、播种量选择50 kg/hm2的栽培方式,水稻的生长状况相对较好.
Abstract
In order to explore the effects of different cultivation methods on the population structure and yield of rice,Hanshou County was selected as the test site,four cultivation methods were set up,including artificial sowing,mechanical transplanting,artifi-cial sowing and aerial sowing,and the growth status,yield and economic indicators of rice under different cultivation methods were compared.The results showed that the growth of rice was relatively good with artificial direct seeding method and 50 kg/hm2 plant-ing method.
