不同配比桉树专用肥对桉树生长及元素吸收的影响
Effects of Different Ratios of Special Fertilizer on Eucalyptus robusta Growth and Absorption of Major Elements
摘要
Abstract
This study was set fertilizer A(m(N) : m(P) : m(K)=15 : 9 : 11),fertilizer B (m(N) : m(P) :m(K)=17.6 : 7.2 : 10.3),no fertilization (control),the changes of elements in each part of Eucalyptus robusta (DH32-29) was discussed. The results showed:1) Fertilizer A positively promoted the growth of Eucalyptus robusta.2) Fertilizers A and B significantly increased the absorption of N,P and K in different organs of Eucalyptus robusta.Fertilizer B had higher effect on N absorption in root and leaves,P absorption in leaves than fertilizer A,but there was no significant difference in K among fertilizer A and B.3)The absorption of N and P in Eucalyptus roots under the treatment of Eucalyptus robusta leaves and A treated with A and B was not limited,while the P absorption of Eucalyptus robusta roots under the control and B treatment was limited.4)The effect was significant at fertilizer A on the Ca absorption of Eucalyptus robusta.But the effect of fertilizer N,P,K ratio on the Mg absorption of Eucalyptus robusta was not significant.关键词
