摘  要:
[目的]探寻直播稻密度与不同类型中粳品种产量的关系。[方法]以镇稻99、连粳7号和淮稻5号为试验品种,分析基本苗密度对3个品种产量及其构成因素的影响。[结果]基本苗密度对3个品种产量影响不显著,淮稻5号基本苗密度为121.50万/hm2时产量最高;连粳7号基本苗密度为98.55万/hm2时产量最高;镇稻99基本苗密度为100.00万~111.00万/hm2时产量较高。[结论]直播稻镇稻99、连粳7号基本苗密度定在105.00万/hm2左右较为合适,而淮稻5号基本苗密度定在120.00万/hm2左右比较适宜。

摘  要:
[Objective] The aim was to explore the relationship of direct seeding rice density and different medium japonica rice yields.[Method] With Zhengdao 99,Lianjin 7 and Huaidao 5 as the subjects,the effects of basic seedlings density on yields and constitute factors of 3 medium japonica rice were analyzed.[Result] The effects of basic seedlings density on yields of 3 medium japonica rice were not significant,the yields of Huaidao 5 was highest when the basic seedlings density was 121.50 × 104 per hectare,the yields of Lianjin 7 was highest when the basic seedlings density was 98.55 × 104 per hectare,the yields of Zhengdao 99 were highest when the basic seedlings density were 100 × 104 ~ 111 × 104 per hectare.[Conclusion] It was suitable when the basic seedlings density of Lianjin 7 and Zhengdao 99 were about 105.00 × 104 per hectare,and the basic seedlings density of Huaidao 5 was about 120.00 × 104 per hectare.
