不同旱稻产量构成性状的研究

Studies on Different Yield Components Traits of Aerobic Rice

以16个参试旱稻品种(系)为试材,采用随机区组设计,研究了产量与产量形成的主要因素之间的关系。研究结果表明:春丰A006产量高于对照旱9710,其差异达到极显著水平。其株高、千粒重、有效分蘖、成粒率对产量作用更为明显;高产的原因主要是生物量较高。在保证穗数的基础上提高成粒率和千粒重,更有利于旱稻产量的进一步提高。

Using 16 aerobic rice cultivars as materials the relation of yield and main yield components traits were studied by randomized block design.The results showed that‘Chunfeng A006’has significantly higher yield than‘Han9710（’CK）.Plant Height,1000-grain weight,valid tiller,ripen grain number played important role in yield.The reason for high yield resulted from high biomass.Increasing the ripen grain number and 1000-grain weight on the basis of feasible spike number may further improve rice yield.
