Abstract:
Taking the grafted four-year-old grey jujube from Alar city of Xinjiang as the test material,the effects of the different N(N1,N2,N3),P(P1,P2,P3) level on leaf chlorophyll content,leaf area index,leaf net photosynthetic rate,the content of total nitrogen,total phosphorus of newborn and perennial leaves were studied by randomized block design,nitrogen and phosphorus were not applied for comparison,in order to provide a reference for local jujube tree fertilization.The results showed that leaf chlorophyll content,leaf area index and leaf net photosynthetic rate increased with the increase of leaf age under different nitrogen and phosphorus application treatments,and leaf chlorophyll content under N3P3,N3P1 and N1P3 fertilization treatments was higher than other treatments.On the whole,leaf area index under N1P3 and N2P2 fertilization increased well with the growth process of jujube.With the continuous growth of jujube trees,the net photosynthetic rate of leaves at the final flowering stage was significantly higher than that at the initial flowering stage,and the net photosynthetic rate was the highest under N1P3 fertilization treatment.The total nitrogen content was perennial than newborn,and the total phosphorus content was perennial than newborn.
