摘 要:为研究机条播稻茬小麦适宜播种量和行距,在京山县开展不同播量和行距组合田间试验。结果表明:不同行距间产量差异显著,随着行距的增加,小麦产量呈现先增加后降低的趋势;不同播量间产量差异不明显且行距和播量的互作效应不显著。建议在湖北中南部稻茬麦区,机械条播播量设置为150.0-187.5 kg/hm2,行距控制在22.2 cm左右。In order to study the optimum sowing rate and row spacing for mechanical row-sowing wheat growing in the land after rice harvest, field experiment was conduct to study the effect of sowing rate and row spacing on grain yield in Jingshan County. The results showed that the effect of row spacing on wheat yield was remarkable, and the yield first increase and then decrease with the increase of row spacing. The difference was insignificant between different sowing rate, and the interaction between row spacing and sowing rate was also not significant. To get higher grain yield, the optimum sowing rate and row spacing were 150.0- 187.5 kg/hm2 and 22.2 cm for mechanical row-sowing wheat planted in the harvested rice fields in middle south Hubei Province.
