对4年生大宽行混农间作模式下桉树生长特征进行了研究.结果表明,桉树的保存率、树高、胸径、单株材积在同一株距下均随着带距的增加而增加,变异系数、单位面积蓄积量在同一株距下均随着带距的增加而降低.混农模式在(14 m+1.3 m)×1.25 m配置模式下的各生长指标均优于3种对照和其他配置模式.树高、胸径、单株材积、单位面积蓄积量分别为14.1 m、12.3 cm、0.075 2 m~3/株、78.629 m3/hm~2,分别比对照4.00 m×1.50 m高19.5%、32.26%、98.4%、27.13%.单位面积蓄积量在4、6、8 m带距下的配置模式均显著大于3种对照,为74.798~117.181 m~3/hm~2.
對4年生大寬行混農間作模式下桉樹生長特徵進行瞭研究.結果錶明,桉樹的保存率、樹高、胸徑、單株材積在同一株距下均隨著帶距的增加而增加,變異繫數、單位麵積蓄積量在同一株距下均隨著帶距的增加而降低.混農模式在(14 m+1.3 m)×1.25 m配置模式下的各生長指標均優于3種對照和其他配置模式.樹高、胸徑、單株材積、單位麵積蓄積量分彆為14.1 m、12.3 cm、0.075 2 m~3/株、78.629 m3/hm~2,分彆比對照4.00 m×1.50 m高19.5%、32.26%、98.4%、27.13%.單位麵積蓄積量在4、6、8 m帶距下的配置模式均顯著大于3種對照,為74.798~117.181 m~3/hm~2.

The growth characteristics of eucalyptus in the mode of four-year-old big wide line of mixed agricultural intercropping were studied.The results showed that the preservation rate of eucalyptus,tree height,chest diameter,timber volume of single plant began to increase with the growth of belt distance under the same spacing in the rows.Coefficient of variation,volume per unit area began to decrease with the increase of belt distance under the same spacing in the rows.Each growth index of mixed agriculture in the configuration mode of (14 m+1.3 m)×1.25 m surpassed three kinds of control and other configuration mode.Tree height,chest diameter,timber volume of single plant,volume per unit area were 14.1m,12.3 cm,0.075 2 m3,78.629 m3/hm2respectively,higher than control( 4.00 m×1.50 m) 19.5%,32.26%,98.4%,27.13% resp.Configuration mode of volume per unit area under the circumstances of 4,6,8 m were all significantly higher than three kinds of control,between 74.798 m~3/hm~2 and 117.181 m~3/hm~2.
