Abstract:
Taking 20-year-old Korla fragrant pear as material,the effect of different treatments of N,P,K on photosynthetic characteristics of fruit enlargement stage of it was studied in field condition.The results showed that the diurnal variation curves of Pn of Korla fragrant pear presented double-apex curves,and had a phenomenon of photosynthetic‘noon breaking’.It could promote the net photosynthetic rate of leaves to apply fertilizer N,P and K,but the fertilizer excess were all not benefit.Through the establishment and analysis of model,the role of fertilizer N,P and K to Pn of Korla fragrant pear leaves was in order of K＞P＞N.The interaction effect of P and N,K and N were coordination,but K and P were antagonistic effect.Taking the Pn as optimal composite scheme,the quantity of N,P,K for individual tree was 0.450~0.500 kg,0.550~0.600 kg,and 0.100~0.150 kg respectively.
