各地加速小麦世代育种的方法很多。沈阳地区过去多采用南方夏繁或冬繁,除耗资较多外,还常受风雨、干旱、土地、人力等条件的限制和影响。为此,从1979年开始,我们根据沈阳地区的气候条件,初试就地夏繁晋代,并对春小麦夏播期间的生育特性及对环境条件的要求等方面进行了研究。一、沈阳地区气侯资源的基本情况沈阳3～9月及10月气温、日照情况见表1。由表1看出,沈阳地区除10月温度开始显著下降、雨量较少外,7～9月温度较高,日
There are many ways to speed up wheat generation breeding around. Shenyang area in the past to use the South summer or winter Fanfan, in addition to more cost-effective, but also subject to wind and rain, drought, land, manpower and other conditions and restrictions. Therefore, starting from 1979, we conducted a preliminary study of the summer, summer and prosperity of the Jin and Jin dynasties based on the climatic conditions in the area and conducted research on the characteristics of fertility and the requirements for environmental conditions during the summer sowing of spring wheat. First, the basic situation of climate resources in Shenyang Shenyang 3 ~ September and October temperature, sunshine situation in Table 1. Table 1 shows that in addition to the temperature in October in Shenyang began to decline significantly, less rainfall, July to September higher temperature, day
