- Abstract:
- Resistance control action about anti-transpiration foliar fertilization to the water use efficiency (WUE) were studied in order to enhance the plant survival. By using the pot method, the tests were conducted to Prunus armeniaca L. with different foliar fertilizers under conditions of sufficient water supply. The net photosynthetic rate (Pn), transpiration rate (Tr) of Prunus armeniaca L and their environmental factors were measured so as to get the water use efficiency (WUE) indicators by Pn/Tr. The results showed that net photosynthetic rate (Pn) and transpiration rate (Tr) had two peaks at respectively during the daylightunder the treatments of different foliar fertilizer density with midday depression phenomenon. WUE’ maximum presented at 8:00 and the WUE got a trough from 10:00 to 16:00, and the period remained stable, after 16:00, it gradually increased. It showed that WUE reached the highest while WUE of comparison was the minimum when used the A of foliar fertilization. The final study results showed that best formulation was type A, so under the arid conditions, we can choose to spray type A of foliar fertilization on leaf surface to improve plant water use efficiency (WUE), and improve survival rate of stock. Spraying the anti-transpiration foliar fertilization on leaf surface can not only provide the necessary nutrients required for plant growth, but also inhibit plant transpiration, improve plant water use efficiency (WUE), and improve the survivability of plants to some extent.
