小麦株高与主茎叶片数是植株的重要性状。利用主茎叶龄与生长发育的对应关系,可以预测植株的幼穗分化和生育进程。更多的研究报道,以主茎总叶数作为品种类型划分标记性状之一。本文以研究不同生态条件对植株重要性状的影响及其变化规律,以及温、光、水等因子对株高,主茎叶数的促抑效应。以期通过研究分析,为小麦生产选择适播期及合理栽培管理提供参考。一、材料与方法试验在我所谢桥坝上进行,海拨254米,年均温16.7℃,全年累计日照时数为1180.8小时,年降雨量为1271.6毫米,以5～6月份雨
Wheat plant height and number of main stem leaves are important traits of plants. Using the relationship between leaf age of main stems and growth and development, we can predict the spike differentiation and growth of plants. More research reports, the main stem of the total number of leaves as a type of marker divided one of the traits. In this paper, the effects of different ecological conditions on the important traits of plants and their changing rules, as well as temperature, light, water and other factors on the plant height, the number of main stems inhibitory effect. With a view to research and analysis, provide a reference for selecting suitable sowing date and reasonable cultivation and management of wheat production. I. Materials and Methods The experiment was carried out on a Xieba dam which was under my approval. The altitude was 254 meters with an average annual temperature of 16.7 ℃. The accumulated sunshine duration for the whole year was 1180.8 hours and the annual rainfall was 1271.6 mm. Rainfall occurred in May-June
