Influence on Photosynthetic Characteristics and Yield of Zizyphus Jujube under Different Treatments of N, P, K
Designing different treatments of water and fertilizer under drip irrigation, and Studying Photosynthetic characteristics, yield and fruit quality of Zizyphus Jujube. The results show that it is advantage for Pn of Zizyphus Jujube leaves to apply more fertilizer N in soil. it can low Tr of Zizyphus Jujube leaves and decrease the consumption of soil water. it can increase the single fruit weight and yield to apply more fertilizer N and P to soil in range of designed level, and improve the fruit shape index. It can increase the contents of revertose and vitamin C in fruit of Zizyphus Jujube to apply more fertilizer K to soil, and it can increase the content of protein in fruit of Zizyphus Jujube to apply more fertilizer N to soil
