水氮耦合对枣树生长与产量的影响
Influence on Growth and Yield of Zizyphus Jujube under Coupling of Water and Nitrogen
摘要
Abstract
Different treatments of water and fertilizer were designed under drip irrigation to study growth and yield of Zizyphus Jujube under coupling of water and nitrogen.The results show that the physiology growth of branches is the fastest in summer in the annual growth cycle of jujube tree,but the physiological growth of leaves is the fastest in spring.It can promote growth and development of base diameter,tree height and shoot of jujube tree to irrigate more water and apply more N to soil in the range of designed level;and it can also increase LAI,but can reduce the leaf thickness and chlorophyll content;in addition,it can reduce the single fruit weight and fruit shape index to irrigate more water to soil.Through the establishment and analysis of model,the role of water and N in yield of jujube tree is in order of Nwater.The interaction effect of water and N is coordination for yield.The quantity of watering is 5 250~6 000 m3/hm2,and the application quantity of N is 300~375 kg/hm2 by considering the yield as optimal composite scheme.关键词
