在研究岱字棉15号适期播种棉株芽的同步性基础上,继续研究岱字棉15号不同播期以及若干陆地棉中熟品种之棉株芽的同步性,证实棉株随着播种期的推迟,主茎顶芽内部分化叶片数有所减少,果枝始节有所提高。陆地棉中熟品种亦具有类似趋势。因而证实(Ⅰ)文预测公式具有广泛应用价值。 “同步”在栽培技术上的应用也作了阐述。
On the basis of studying the synchronicity of cotton buds suitable for sowing Dai Dai Zi No.15, the synchronization of cotton buds of Dai Zi No.15 sowing date and a number of mid-ripe cotton cultivars was further studied. Postponing the period, the number of differentiated leaves in the main stem buds decreased, fruiting branch beginning increased. Upland cotton varieties also have a similar trend. Therefore, it is confirmed that (1) Wen predicting formula has a wide range of application value. The application of “synchronization” in cultivation technology is also elaborated.
