直播与插秧对不同粳稻品种产量及经济效益的影响

Effects of Direct Seeding and Transplanting on Yield and Economic Benefits of Different Japonica Rice Varieties

为筛选寒地适合直播种植的水稻品种,本试验对吉林省主栽品种通禾819、吉玉粳、通禾66进行直播和插秧种植,对不同种植方式下各水稻品种的产量和经济效益进行比较。结果表明:中早熟品种通禾819在直播方式下比插秧方式产量变化较小,并且其在直播种植条件下经济效益有所增加,可以适当缓解当下劳动力不足的现状,并帮助种植户节约成本、增加收入。

In order to screen out the better rice varieties suitable for direct seeding in cold region,in this experiment,Tonghe 819,Jiyujing and Tonghe 66,the main cultivars in Jilin Province,were planted by direct seeding and transplanting,studied the yield and economic benefits of different japonica rice varieties in cold region under the planting mode of direct seeding and transplanting.The results showed that the yield of medium and early maturing cultivar Tonghe 819 had little change in direct seeding mode compared with transplanting mode,and the economic benefits of direct planting increased.Direct seeding could appropriately alleviate the current shortage of labor force,help farmers save costs and increase revenue.
