摘要
[目的]为崇明水稻生产上推广机插秧种植方式提供依据。[方法]以上海市主推的高产优质杂交粳稻新组合花优14为研究对象,对比分析了机插秧和人工撒播2种不同种植方式对其产量以及种植经济效益的影响。[结果]机插秧比人工撒播增产1 000.35kg/hm2,增幅11.40%,经济效益增加1 701.77元/hm2,增幅10.82%。[结论]对杂交粳稻种植而言,机插秧种植方式优势较为明显。
[Objective] The aim was to provide the basis for extension of rice planting patterns of transplanting by machine in the rice production of Chongming island.[Method] The new hybrid japonica rice combination Huayou 14 with high-yield and good-quality which was the main popularized variety of rice in Shanghai as the research material,the effect on yield and growing economic benefit of hybrid japonica rice 'Huayou 14'under two different planting patterns were compared and analyzed.[Result] The results indicated that the yield of transplanting by machine was higher than artificial direct sowing,increased 1 000.35 kg/hm2,the growth rate of 11.40%,the economic benefit increased 1 701.77 yuan/hm2,the growth rate of 10.82%.[Conclusion] The planting pattern of transplanting by machine was better than artificial direct sowing for hybrid japonica rice planting.
