| Abstract: |
| 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. |
