| Abstract: |
| The effects of water treatment on photosynthetic characteristic of radish under plastic film mulch were studied. The results showed that Chl content of treatment was less than that of the contrast under the same water treatment. After 40d of seeded, photosynthetic rate of treatment excelled the contrast, and photosynthetic rate of all treatments reached the peak. After water irrigated, photosynthetic rate and transpiration rate of radish had the same trend, but water use efficiency was reverse; photosynthetic rate of treatment did not increase, but transpiration rate increased remarkablely before 14∶00 under the same water treatment. |
