中国人. 通过对唐山地区＂107杨＂人工林林农间作中不同土壤质地、株行距的试验研究,以期为生产和研究提供科学依据。结果表明：在相同的立地条件、同一栽培管理措施情况下,不同土壤质地及株行距配置对林分的树高、胸径和单株材积的影响有所差异。7年生＂107杨＂人工林以壤土中林分各生长指标最高,粘土次之,沙土最低。6年生＂107杨＂人工林造林采用2 m×2 m×10 m和2 m×4 m×8 m的株行距较为合理,有利于林分的生长,林分各生长指标随着林龄的增大而显著增加;而株行距为2 m×3 m×9 m时,林分表现出生长较差,配置不合理。[著者文摘]

The study on different soil textures and row spacings of alley cropping of artificial forest of Populus×euramericana ＇Neva＇ in Tangshan showed that,under the same situation of site condition and planting management,the effects of the different soil textures and row spacings on the tree height,diameter at breast height and mean individual volume are somewhat different.Growth indexes of the loam soil of the 7 years old artificial forest of Populus×euramericana＇Neva＇ were highest,followed by clay soil and sand soil.Row distance at 2 m×2 m×10 m or 2 m×4 m×8 m of the 6 years old artificial forest of Populus×euramericana ＇Neva＇ is more advantageous to the stand growth in Tangshan and the average diameter increased with age.However,row distance of 2 m×3 m×9 m is not beneficial for plant growth.[著者文摘]
