:1995～ 1997年固原地区农科所利用日光温室技术 ,对春小麦冬季就地加代的可行性及适应性进行了探索 ,并对其在温室内的生长发育表现、幼穗分化进程、栽培管理技术等进行了系统研究。结果表明 :温室种植的春小麦正长正常 ,发育良好 ,其幼穗分化进程与田间种植的是一致的 ,不同的是温室种植的春小麦营养生长迅速、旺盛、进程快、时间短 ,而生殖生长缓慢、持续时间长、速度慢、形态特征变大。确定适宜播期为 8月 15日～ 9月 15日 ,最佳播期为 8月 15日～ 9月 10日 ,并提出温室内控温控湿等一系列栽培措施。研究认为利用日光温室加代是缩短春小麦育种年限的又一途径。
: From 1995 to 1997, using the solar greenhouse technology of agricultural sciences in Guyuan district, the feasibility and adaptability of spring wheat in situ generation in winter were explored. And its growth and development performance, panicle differentiation process, cultivation and management techniques Conducted a systematic study. The results showed that the spring wheat grown in the greenhouse was positive and well developed, and its spike differentiation was consistent with that of the field. The difference was that the spring wheat grown in green house grew rapidly and rapidly, the process was fast, the time was short, and the reproductive growth was slow , Long duration, slow, morphological features become larger. The optimum sowing date was from August 15 to September 15, and the best sowing date was from August 15 to September 10, and a series of cultivation measures such as temperature control and humidity control in greenhouse were proposed. The research suggests that the use of solar greenhouse plus generation is another shortcoming of shortening spring wheat breeding years.
