| 摘 要： | 为了充分利用有限的水资源，调节土壤水分状况，根据枸杞生育期内土壤水分的变化特点，利用时域反射仪，在非称重式蒸渗仪（测坑）中研究不同灌水量下枸杞土壤水分动态变化和耗水规律。结果表明：灌水是影响枸杞园内土壤水分变化重要因素，土壤水分的消耗主要依靠灌水来补充；枸杞耗水量显著受土壤水分的影响，土壤越湿润，耗水量也越大；受温度和枸杞生长的影响，不同水分条件下枸杞月耗水高峰在5-9月，最高月耗水量在7月；最高旬耗水量分别在5月下旬、6月中旬和7月下旬；阶段耗水量的趋势均表现为：盛果期＞盛花期＞营养生长期＞秋果生长期＞秋果采收期。

| Abstract: | In the growth period of Lycium,according to soil moisture characteristics,the author full used of limited water resources and regulated soil moisture.Using time domain reflectometry,the soil moisture tendency and evapotranspiration water consumption rule of Lycium were studied by different irrigation in non-weighing lysimeter(test pit).The results showed that:the irrigation was an important factor in soil moisture in Lycium field,the soil moisture consumption main dependence irrigates supplemented;the consu... |
