摘要
试验结果表明有孔拱棚覆盖可有效地调节环境温湿度变化，具降低最高温，提高最低温，减少逆温现象，促进蒸发和蒸腾作用等效应，能有效地防止作物徒长，提高适应能力。适宜孔径孔数的有孔拱棚，可促进西葫芦的雌花分化及生长，利于早期产量的提高。试验证实有孔拱棚覆盖省工省力，能扩大经营规模，是一项高效省力的新技术。
The result of the experiment showed that:small arch shed with perforated plastic film decreased the maximum temperature in it,mitigated the day variation of temperture,decreased the humidity,increased evpotranspiration,avoided the excessive growth of crops,advanced the pistillate flower production and growth and increasedearly yield.Meanwhi,e it may save the manpower of managment.It is the techique of save labor and high effect and may be widerspread in future.
