Influence on Growth and Yield of Korla Fragrant Pear Under Different Treatments of N, P, K
摘要
Abstract
In order to grasp the growth law of Korla fragrant pear and the response of soil nutrients N,P,K.Set different treatments of N,P,K,and monitor the growth and yield of 20 years Korla fragrant pear in growth period.The results showed that fertilization could promote tree growth and fruit development of Korla fragrant pear,and it could improve the yield and fruit shape index.Through the establishment and analysis of model,the effect of fertilizer to yield was in the order of N ＞ K ＞ P.The interaction effect of P and N,K and P were coordination,but K and N were not obvious effect.Taking the yield 27500 ～ 27800kg·hm-2 as optimal composite scheme,the quantity of N was 280 ～ 330kg· hm-2,the quantity of P was 250 ～300kg·hm-2,and the quantity of K was 50 ～60kg·hm-2.关键词
