红松、核桃楸人工混交林到底怎么样?和纯林相比,到底存在着哪些潜在优越因索?哪种混交比例好?在营林事业上有没有推广的意义?我们带着这些问题,在1979年秋,对我县热闹林场的红松、核桃楸人工混交林进行调查研究。从九月五日开始到14日外业结束。选择不同的混交比标准地13块,作了138株解析木,标准地总面积12000平方米。经过内业整理分析,混交比红五楸五生长的最差;红六楸四红松生长的较差;红七楸三;红八楸二红松生长的比较好;但都较红松纯林生长的差些。从红松、胡桃楸二者蓄积的总和来看,红八楸二、红七楸三都高于红松纯林的蓄积。土壤肥力混交林高于纯林。本文重点介绍红松、胡桃楸人工混交林各种不同混交比的生长情况。
Korean Pine, Juglans maudissima mixed forest in the end how? Compared with the pure forest, in the end what are the potential advantages due to cable? What kind of mixed good? In the forest business there is no promotion of significance? We take these questions, in the In the autumn of 1979, we conducted a survey on the artificial mixed forest of Korean pine and Juglans mandshurica in the lively forest farm in our county. From September 5 to 14 on the field of the end. Choose different mixed than the standard 13, made 138 analytical wood, the standard total area of 12000 square meters. After finishing the housekeeping analysis, the mixed growth of Wuxu five was the poorest; the growth of Hongliujiu four red pine was worse; the growth of Hongqiu three was better; Lin growth worse. From the sum of the accumulation of both Korean pine and Juglans mandshurica, the accumulation of red two-rowed trees and three red-rowed trees is higher than that of the pure Korean pine trees. Soil fertility mixed forest is higher than pure forest. This article focuses on the Pinus koreans and Juglans mandshurica mixed forest mixed growth at different rates.
