| 摘 要： | 膜下滴灌是一种既能高效节水,又能适时调控土壤水盐运移的灌水技术.滴灌湿润体交汇区土壤水盐分布特征是影响密植作物正常生长的重要因素.在田间情况下,研究滴头流量、滴头间距、灌水量对滴灌湿润体交汇区的土壤水盐运移的影响.实验结果表明:滴头流量越大,湿润体交汇区土壤含水率越高,土壤盐分淋洗效果越好,在滴头流量1.38 L/h和...

| Abstract: | The Mulched drip irrigation is the irrigation technology which not only can save water effectively,but also can regulate the water-salt transport at the right moment.The soil water-salt transport characteristics in the interference area of wetted volume under the drip irrigation have an important affect on the normal growth of the closely-planting crops.The research was carried out on the soil water-salt transport characteristics in the interference area of wetted volume under drip irrigation in the field,a... |
