Effects of fertilization depth on growth and fruit quality of'Korla Xiangli'
摘要
Abstract
Taking 12-year-old densely planted'Korla Xiangli'pears as the test materials,the effects of four different fertilization depths,namely,fertilization depth of 15 cm(CK),30 cm(T1),45 cm(T2),and layered fertilization(T3),on the tree growth,leaf nutrient absorption,and fruit quality of'Korla Xiangli'pears were studied to provide a basis for the scientific water and fertilizer management of densely planted pear orchards.The results showed that compared with CK,the treatments of T1 and T2 significantly promoted the growth of new shoots of'Korla Xiangli'pears;the SPAD values and leaf areas of the leaves in the treatments of T2 and T3 were significantly increased;the length and thickness of flower buds in the T2 treatment were significantly increased;the net photosynthetic rate and stomatal conductance in the T2 treatment were significantly increased by 30.33%and 40.91%,respectively;the nutrient contents in the leaves were increased in the treatments of T1,T2,and T3,and the contents of total nitrogen,total phosphorus,and total potassium in the leaves in the T2 treatment were increased by 20.24%,15.43%,and 14.11%,respectively.In terms of fruit quality,the contents of soluble solids,glucose,sorbitol,sucrose,and fructose in the T2 treatment were relatively high,which were increased by 6.20%,16.06%,12.98%,36.21%,and 18.01%,respectively,compared with CK,and the organic acid content was the lowest,and the internal quality was the best.In terms of yield,the yields per plant in the treatments of T2 and T3 were significantly increased by 34.39%and 13.23%,respectively,compared with CK.The results of correlation analysis showed that there was a significant positive correlation between leaf area and total nitrogen content in the leaves,a significant positive correlation between soluble solids content in the fruit and total nitrogen content in the leaves,and a significant positive correlation between fructose content in the fruit and total potassium content in the leaves.To sum up,the T2 treatment had the best effect in promoting the growth of'Korla Xiangli'trees,improving leaf nutrient absorption,and improving fruit quality.Therefore,it is recommended that the appropriate fertilization depth for'Korla Xiangli'pears in the main production areas of Xinjiang is 45 cm.关键词
