冬小麦在固原试区的生态适应性
- Title:
- Ecological Adaptability of Winter Wheat in Guyuan Experimental Station
- Keywords:
- ecological adaptability; winter wheat; winter-spring wheat mixture region; relative suitability
- 摘要:
- 通过分析影响作物生产的四大生态因子：光、热、水、肥的供需状况，探讨了在冬春小麦混交区的黄土高原西部种植冬小麦的可行性与不利因素.作者认为：冬小麦在此区光照是适宜的，热量比较适宜.水分不足、肥力缺乏严重影响了冬小麦产量.并提出了发展冬小麦的措施：1、选择和培育抗旱、抗寒品种；2、采取适时早播和保温保水措施；3、增磷补氮、培肥地力.
- Abstract:
- The author an4lysed the supply-demand condition of wheat’s four general factors: light, heat, water and soil nutrition etc which restrict winter wheat growth in Shanghuang experimental district, Guyuan county, Ningxia Autonomous Region.With which researched the possibility and unfavourable factor of development winter wheat in winter-spring wheat mixture region.The result is as follows: light in this region is suitable for winter wheat, heat is relative suitable.Relative suitable water, and lack soil nutrition restricted winter wheat yield seriously.The measures of development winter wheat includ: ①electing and recommending fine varieties that can resistant drought and cold; ②taking reasonable sowing period and measures of keeping temperature and moisture content; ③increasing soil nutrition.
