不同播期对冬小麦产量及产量构成因素的影响
Effects of Sowing Date on Grain Yield and Its Components of Winter Wheat
摘要
Abstract
The effects of different sowing dates on grain yield and its components of winter wheat were studied with the cultivars Tainong 18 and Jimai 22. The results showed that with the delaying of the sowing date, the growth period of winter wheat was postponed; the spike number decreased gradually; the grain yield and 1 000 - grain weight increased firstly and then decreased, and the peak value was present in S2 treatment. The grain number per spike of Tainong 18 increased firstly and then decreased, while that of Jimai 22 increased firstly, then decreased, and increased at last with the sowing date was delayed.关键词
