| Abstract: |
| An experiment with treatments of wood vinegar and sodium naphthalene acetate was carried out to research photosynthetic indexes and yield traits of peanut under different spraying conditions, and to identify the optimal combination. The results showed that pod number and pod weight of peanut were elevated under different spraying treatments. Kernel rates of B3-300N3-20 and B2-300N2-20 were lower than that of the control, but others were increased. Three spraying of 300 times wood vinegar or 20 mg·L-1 sodium naphthalene acetate lowered the plant height. The combination of 600 times wood vinegar and 20 mg·L-1 sodium naphthalene acetate increased effective branch number of peanut. B3-300N3-20 inhibited the photosynthetic rate. In addition to the treatment group of spraying 300 times wood vinegar (B300N0, B300N10, and B300N20), the rest of those showed that SPAD value increasing with the increasing dose of spraying. System cluster analysis showed the best treatment was the combination of 600 times wood vinegar mixed 20 mg·L-1 sodium naphthalene acetate and being sprayed 3 times. |
