为探寻适宜南方鲜食枣园生草栽培的草种，以白三叶、1年生黑麦草和多年生黑麦草为试材，在鲜食枣园分区分别进行生草栽培试验，通过与清耕区的对比，研究不同处理对土壤理化性质的影响。结果表明：①白三叶生草栽培条件下枣园0～15、15～30、30～45 cm的土壤含水量分别比对照高出37.5%、22.4%、15.6%；夏季白三叶生草栽培区地表和20 cm土层的温度分别比对照降低了4.8和6.4℃，降温保墒效果优于其它处理。②与对照相比，白三叶生草栽培区的土壤容重降低，土壤总孔隙度大幅增加，各处理的土壤总孔隙度由高到低依次为白三叶、多年生黑麦草、1年生黑麦草、对照；③生草区0～15 cm土层土壤养分含量都...

In order to explore suitable grass for fresh jujube orchard in Southern China, using white clover,Lolium multilforumand L. perenne as test materials, sod cultivation experiments on fresh jujube were carried out and the effect of different treatments on soil physical and chemical characteristics were studied. The results showed that:① In the condition of culturing white clover, water storage of 0-15, 15-30 and 30-45 cm soil layers could be increase by 37.5%, 22.4% and 15.6% respectively compared with CK; white clover decreased temperature of so...
