乌鲁木齐协作点经过四年的试验,系统地、全面地分析了全国不同类型的31个小麦品种在乌鲁木齐地区生长发育规律及其与温、光条件的关系,充实了传统的小麦生长发育和温、光反应的理论。提出了以小麦品种春播的主茎叶片数、播种——拔节天数、抽穗率、成熟性状等作为划分小麦生态类型的依据。利用人工气候箱所作的辅助试验表明,低温对春性品种通过春化阶段作用不明显,对半冬性、冬性品种通过春化阶段则起促进作用,长日照能缩短春性、半冬性和冬性小麦品种进入三棱期天数,加速不同类型小麦生长发育进程。从小麦籽粒蛋白质含量变异的试验,分析出不同类型品种,不同播种期,对小麦的产量性状、籽粒蛋白质含量与气候因子的关系,对北疆麦区适宜的小麦品种类型的引种、育种、栽培提供了更加丰富的依据。
After four years of experiments, Urumqi collaborative point has systematically and comprehensively analyzed the growth and development of different types of 31 wheat varieties in Urumqi and its relationship with temperature and light conditions, and enriched the traditional wheat growth and development and temperature, Theory of photoreaction. Proposed the spring wheat sowing the number of main stems, sowing - jointing days, heading rate, maturity traits as the basis for the classification of wheat ecological type. Supplementary experiments using artificial climatic chambers showed that low temperature had no significant effect on the passage of spring vernalization varieties and promoted the passage of vernalization stage on winter and winter varieties. Short daylight could shorten spring and semi-winter And winter wheat varieties into the triangular days to accelerate the growth and development of different types of wheat. Based on the experiment of variation of protein content in wheat grain, the relationship among different types of varieties, different sowing dates, yield characters of wheat, grain protein content and climatic factors was analyzed. The introduction, breeding and cultivation of suitable wheat varieties Provide a richer basis.
