| Abstract: |
| A field experiment was conducted to study the effects of green manure on the fruit yields of Ningqi No. 5 wolfberry and soil nutrientstatus, under the condition of halving the amount of fertilizer, which included half chemical fertilizer with organic manure (T1), half chemical fertilizer spreading rapeseed straw manuring (T2), and chemical fertilizer only (CK) treatments. Results showed that, compared with CK, the dry fruit yield of T1 and T2 treatments was significant increased by 24.1% and 19.1%, respectively. Contents of soil organic matter, alkali hydrolysable N, available P, available K of T1 and T2 treatment significant increased by 12.8%, 13.2%, 36.0%, 28.2%, and 60.2%, 23.1%, 28.5%, 57.9%, respectively, at the end of autumn when fruits were harvested. These results indicated that, under the condition of halving the amount of fertilizer, both added organic manure and rapeseed straw manuring could increase the wolfberry fruit yield and the soil nutrient content, and the rapeseed straw manuring was more significant than added organic manure. Therefore, wolfberry interplanting with rapeseed as green manure not only reduced the chemical fertilizer application, but also increased the fruit yield and soil nutrient content of wolfberry. |
