为探明超级稻栽培措施的主攻方向,2009年在福建省29个水稻高产创建示范县(市、区)进行超级稻产量构成因素的调查与分析,并在南平、长汀两地开展超级稻不同叶龄、不同插植密度试验。结果表明:超级稻高产的产量结构特征是穗大粒多,生产上要选择大穗品种,在此基础上采取有效的措施促进有效穗的增加及结实率的提高,以增加单位面积总粒数,提高产量。
In order to find out the main directions of super rice cultivation measures, in 2009, 29 high-yielding paddy-producing demonstration counties (cities and districts) in Fujian Province were surveyed and analyzed for the composition of super-rice yield. Super rice Different leaf age, different planting density test. The results showed that the yield structure characteristics of high-yielding super-high-yielding rice were large spikelets and large spikelets in production. Effective measures were taken to promote the increase of effective spikes and seed setting rate in order to increase the total number of grains per unit area, Increase production.
