摘要
本研究是山东省科委项目“农田节水灌溉综合示范开发研究”子课题“果树滴灌试验”的一部分。１９９０～１９９２年试验表明，秸秆对果树滴灌土壤水热状况有良好的覆盖效应：可增加土壤贮水，降低耗水，调节土壤温度，提高水分利用效率，滴灌加秸秆覆盖这一综合节水措施具有较高的推广价值。
The study is a part of subtask-“drip irrigation test of fruit trees”,which belongs to scientific and technological committee of Shandong province project“The comprehensive developing study of water saving irrigation in farmlands”.From 1990 tO 1992,the test showed that the straw cover has gall effects to heat and water state of soil for drip irrigation of fruit trees, it can increase storage water of soil,reduce water consumption, regulatesoil temperature, raise utilization rate of moisture.So the comprehensive saving water measures of drip irrigation with straw cover has a higher value of papularization.
