- 摘要:
- 为提高葡萄品质与产量,设置3个微喷迷雾时长调控处理(WP1:每天喷水1 h,WP2:每隔1 d喷水2 h,WP3:每隔2 d喷水3 h),对照为常规滴灌不喷水,通过对极端干旱区葡萄在不同弥雾调控方式下微气候因子与葡萄果实生长形态及糖度的监测,分析葡萄园微气候因子变化规律及其与葡萄果实生长形态和糖度的关系。结果表明:采用弥雾调控可有效降低葡萄园温度和增加湿度,各处理与CK处理相比,白天平均温度低2.1~2.9 ℃,夜晚平均温度低0.9~2.1 ℃,平均温度差低0.8~1.1 ℃,平均温度低1.5~2.5 ℃,白天平均湿度高5.7%~7.6%,夜晚平均湿度高4.7%~6.0%,平均湿度高5.0%~6.8%。同时可促进葡萄果实生长和糖度累积,WP1、WP2和WP3与CK处理相比,果粒纵径高出1.76,1.63和1.51 mm,果粒横径高出180,1.71和1.43 mm,果粒均重高出0.26,0.24和0.16 g,糖度高出5.5%、0.7%和4.1%。其相互关系表明,可以用白天平均温度、平均温度和夜晚平均湿度对该地区葡萄生长和糖度变化进行分析和预测。
