摘 要 ：作者对黄淮海及长江中游平原境内水热条件与地貌成因不同的6个平原单元进行了重点考察,并对林木生长有关的11种土壤进行了野外调查与土壤理化分析,按养分含量与障碍因子综合评价了土壤肥力与宜林特性;应用带状和块状样地调查法,测定各类土壤上多个样地内标准木的树高、胸径和单株材积年平均生长量,再求算各类土壤上的平均值。土壤与林木生长关系的对比研究表明,不同杨树品种和无性系以及其他树种,在其适生的土壤上可获得较高的生长量,这有助于该地区正确选择宜林树种和合理地进行良种推广工作,做到因地适树,提高平原造林质量。

Abstract:This paper deals with the relationship between soils and mean annual Increment single poplar tree in the vast plain of eastern China. According to the climate, the geomorphy, the parent materials, and the groundwater level, soils of this region may be divided into ten types. The sequence of their fertility is as follows: grey fluvo-aquic soil, red clayed fluvo-aquic soil, loamy fluvo-aquic soil, fluvo-aquic cinnamon soil, desaline fluvo-aquic soil, carbonate cinnamon soil, shajiang black soil, saline fluvo-aquic, sandy fluvoaquic soil and solonchak. Compared with the forest soil in mountainous region, the organic matter content and total nitrogen content in all plain soils are poor. Except soil available potassium, most plain soils are also poor in available nitrogen and especially available phosphate. Both in the soil or in the ground water all over the plain the calcium is very abundant, it suits poplar-calciphile very well. The datum of mean annual increment of 16 poplar clones and 3 other broad-leaved tree species in different soils have been given in this paper. According to the results of the former study, it is proved that each poplar species has its own suitable site.
