种植密度对冬小麦产量及其构成因素的影响
Effects of Planting Density on Yield and Its Components of Winter Wheat
摘要
Abstract
Taishan 28 , Zhongyu 9398 and Xinmai 26 were used as materials and three density treatments were set to study the effects of planting density on yield and its components of winter wheat .The results showed that different varieties , planting densities and their interaction had significant influences on yield of winter wheat .Variety and planting density had significant effects on spike number and grain number per spike .The effect of variety on 1 000-grain weight reached to significant level , while that of planting density on 1 000-grain weight was not significant .The optimal planting density for Taishan 28 , Zhongyu 9398 and Xinmai 26 was 3.00, 3.00 and 2.25 million seedlings per hectare respectively .Because of different variety traits, the improving of Taishan 28 and Xinmai 26 should emphasize on grain number , and Zhongyu 9398 should emphasize on spike number .关键词
