摘要
采用超级稻晚稻中熟组合丰源优299,进行了不同基本苗数的大田对比试验。研究结果表明,不同基本苗对丰源优299的产量、经济性状及其他农艺性状均有显著的影响,以插植178.5万苗/hm2时的产量最高,综合农艺性状最佳。并提出,为了充分发挥超级稻组合的增产潜力,应采用相应的栽培技术和管理措施。
In this paper, we had a contrast experiment with the different basic seedling of later super rice combination-Fengyuanyou 299. The results showed that the grain yield,economic and agronomical traits of Fengyuanyou 299 can be seriously affected by the different basic seedlings.The grain yield of super rice-Fengyuanyou 299 planted in 1 785 thousand seedling per hm^2 was suitable and its yield was highest and its comprehensive agronomical traits was the best in this condition. In this paper it was suggested that we should improve the cultivation technique and management measure for the potential yield of the super hybrid rice combination.
