春小麦适期早播增产这一事实已被大家公认,我们在多年生产实践的基础上,通过三年小区试验,较系统地观察适期早播与植株器官建成、产量结构等生物学数量性状的关系并以高产良种新春二号(主茎占生理优势类型)和新疆当前大面积推广品种赛洛斯(分蘖占生理优势类型)两个品种间影响的差异,以便为运筹有关措施提供参考。 一、材料与方法 试验于我院试验站进行。1984年作播期试验,进行系统观察。根据试验结果,1986～1987年对春麦出叶特点、器官建成、同伸关
The fact that spring wheat is suitable for early sowing and yield increasing has been widely acknowledged. On the basis of many years of production practice, we systematically observed the biological quantitative traits of early sowing and plant organ formation and yield structure through three-year plot experiment The relationship between the two cultivars, Xinchun No.2 (main stem dominant species) of high yielding cultivar and current large-scale popularizing cultivar Cyrus (tillering predominantly dominant genus) in Xinjiang was discussed in order to provide references for the operation of these measures. First, the material and method test in our hospital test station. 1984 sowing test, systematic observation. According to the test results, from 1986 to 1987 on the characteristics of spring leaves, organs built, Tongren off
