Abstract:

Using accompanying plants sage, coreopsis and milk vetch as research objects, the objective of this study was to explore their effects on soil nutrients, shoot and leaf growth, and fruit quality of Myrica rubra cv.Ding'ao. The results showed that the accompanying plant coreopsis significantly increased the content of organic matter, nitrate nitrogen and available potassium in the soil, increasing by 7.9%, 51.3%, and 23.8% compared with the control, respectively. The treatments of coreopsis and milk vetch have a certain promoting effects on the growth of shoots and leaves of Ding'ao. Compared with the control, the shoots length was increased by 8.1% and 8.8% respectively, and leaf area was increased by 6.6% and 8.4%. The treatment of coreopsis has a significant effect on the improvement of fruit quality. Compared with the control, the hardness and the content of vitamin C, total amino acids, total sugar, total phenolic was increased by 9.8%, 32.4%, 10.9%, 16.9% and 8.9%, respectively. In summary, the present study screened the accompanying plant coreopsis that was suitable for the growth of Ding'ao, which has a significant effect on the improvement of soil nutrient, shoot and leaf growth, and fruit quality of Myrica rubra.
