| 中文摘要: |
| 在亚热带丘陵区幼龄茶园通过连续4 a的大田对比试验,研究了茶园间作白三叶草对土壤水分时空变化的调节效果和其他生态综合效应,分析了其对茶树生长、茶叶品质和产量的影响。结果表明:与清耕茶园相比,茶园间作白三叶草提高了关键土层(0~20 cm)和关键时期(4~6月)的土壤水分,促进了深层土壤水分向上层移动,提高了水分利用率,延缓和缩短了干旱时间,具有良好的提水保墒抗旱效果,同时改良了土壤环境,抑制了杂草生长,减少了病虫害发生率,促进了蚯蚓的生长,改善了茶叶品质,提高了茶叶产量,增产幅度达50.67 g/m2。 |

| Effects of intercropping white clover in young tea plantation on spatial and temporal variation of soil moisture and other ecological factors as well as on the growth of tea tree,the quality,and the yield of tea were studied in subtropical hilly region through continual 4 year-large-field contrast experiments.The results were as follows: Compared to clean tillage tea plantation,the soil moisture in the tea plantation of intercropping white clover in the key soil layer(0～20 cm) and the key growth period(April-June) was higher.The deeper water went up with high water efficiency.Drought was postponed and shortened with great well effect of upgrading and keeping deeper soil water.Meanwhile,intercropping white clover improved the soil environment,controlled weeds and pests,enhanced the growth of earthworms,bettered the quality of tea,and increased the yield of tea.The tea output of plantation with intercropping clover increased by 50.67 g/m2. |
