| 摘 要： | 将产量构成因素分解成(基本苗×单株分蘖数×成穗率)(×每穗颖花数×结实率)×千粒重,进一步分析了各产量构成因素与产量的关系,结果表明:667 m2穗数与产量呈抛物线关系;成穗率、结实率和667 m2载花量与产量呈极显著的正相关;结实率与成穗率呈正相关。据此提出了“稳定穗数、主攻大穗、争取粒重”的技术路线和培育叶蘖同伸壮秧、少本合理稀植,“稳促蘖、中控苗、后攻粒”的栽培对策。 |
| 关 键 词： | 产量构成因素 基本苗 栽培对策 叶蘖同伸壮秧 |

| Abstract: | The rice yield components could break up into(basic seedlings×tiller numbers per plant×percentage of ear bearing tiller)×(the number of spikelet per panicle×seed-setting percentage)×1000-grain weight.Based on the analysis of these factors,the results showed that the relationship between the mature spike numbers and the rice yield could be expressed by parabola curve and the significant positive correlations were showed among the rice percentage of ear bearing tiller,seed-setting percentage,a mount of flowers and its yield,while the positive correlations was also showed between seed setting percentage and percentage of ear bearing tillers.Accordingly,the technical paths of holding spikes steadily,majoring in large spikes and striving for heavy seeds were put forward.At the same time,the rice cultivation strategies were made that we should enhance the growth of leaves and tillers at the same stages,plant thin appropriately,enhance tillers occurrence,control seedlings at mid-growing stages,then finally promote the weight of the rice seeds. |
| Keywords: | Yield components Basic seedlings Cultivation strategy Growth of leaves and tillers at the same stages |
