| 中文摘要: |
| 在分期播种试验的基础上,结合当地多年气象资料,分析了河西走廊东部地膜棉花种植的小气候效应、适宜时间及区域分布,旨在为更好地开发和利用当地的气候资源提供依据。分析认为:不同播种时间对河西走廊东部地膜棉花产量影响很大,日平均气温稳定通过10℃初日后第4天为适宜播种日期。在河西走廊东部,海拔1100～1380m之间的平川区为地膜棉花适宜种植区,海拔1380～1450m之间的平川区为地膜棉花可种植区,海拔1450m以上地区不宜发展地膜棉花。在适宜种植区,地膜棉花的适宜播种日期一般为4月8日～4月22日。 |
| 英文摘要: |
| On the basis of different sowing date experiment, combining with local climate data, the regional distribution, best sowing date and field microclimate change of mulching cotton were analyzed. The result shows that: the different sowing date greatly affects the yield of mulching cotton, the best sowing date is the forth day after the first day of daily mean temperature≥10℃. In the east part of Hexi corridor region, the region with elevation of 1100-1 380 m is suitable zone of mulching cotton, the region with elevation of 1380-1450 m is cultivatable zone, the area with elevation of above 1 450 m can not cultivate mulching cotton. The best sowing date is April 8-22. |
