| 中文摘要: |
| 在生产园行间播种多年生黑麦草、紫花苜蓿、白三叶草,研究其对土壤理化性状和土壤含水量的影响。结果表明:生草可改善土壤物理性状,使土壤容重平均降低5.68%,总孔隙度提高6.15%。同时生草可降低葡萄园土壤水分含量,在葡萄根系生长的土层(0～60cm)范围内,行间种植白三叶草对土壤含水量影响较大,紫花苜蓿影响较小。 |
| 英文摘要: |
| On the condition of natural raining, the effects of White Clover(Trifolium), Perennial Ryegrass (Lolium perenne) and alfalfa (Medicago sativa) on soil water content in Cabernet Sauvignon vineyard were studied. The results indicated that green coverings improved soil physical characteristics, soil bulk density decreasing by 5.68% and the soil porosity increasing by 6.15%. While soil water content under green coverings was obviously reduced, among 3 kinds of grass, White Clover (Trifolium repens) reduced soil water content evidently and Alfalfa (Medicago sativa) affected it weakly in root zone. |
