毛竹（ph.pubcesens）原产在我国长江以南酸性黄壤和红壤地区,浙江、江西、湖南三省是毛竹的中心产区,约占全国毛竹林面积60％。我省苏南丘陵山区分布面积也较大,文献记载它要求最适PH为4.5—7。近年来,随着毛竹北移工作的大力开展,栽植面积也逐渐扩大。由于北移的气候条件和土壤条件的不同,在引种过程中出现一些新问题。据陕西省生物资源考察队研究报导,毛竹在陕西、山西、河南等碱性或强碱性土壤上发生黄枯病（暂定名）,主要是某些微量元素溶解度降低,呈不可吸收状态存在,也有的认为是土壤缺乏有效铁,而引起生理性的病害,这些宝贵经验对我省开展毛竹北移工作是值得引起重视的。 我省盐城地区自1958年引种毛竹,现在东部滨海盐土地区获得成功,在部分林场和社队已郁闭成林,有些新造竹林成活发笋都较正常。但究竟能否正常生长,人们疑问很多。为了探索毛竹的适应情况,寻求发展途径,解决我省竹材自给问题,我们于1977-1978年调查该区15处新老毛竹引种点的土壤和林分生长状况,收集群众栽培毛竹的经验,并在射阳林场选择不同含盐量的土壤进行造林试验,定期观察土壤盐分变化和生长情况,本文依据两年来调查和观察的资料,仅就这个地区毛竹土宜问题进行初步分析。 Bamboo (ph.pubcesens) native in China’s southern Yellow River acidic soil and red soil, Zhejiang, Jiangxi, Hunan Province is the center of bamboo production, accounting for about 60% of the country’s area of ​​bamboo forest. The province of southern Jiangsu hills and mountains distribution area is larger, the literature records it requires the most suitable PH is 4.5-7. In recent years, with the vigorous development of the northward shift of bamboo, planting area has also gradually expanded. Due to the different climate conditions and soil conditions moving north, some new problems appeared during the introduction process. According to the report of Shaanxi Provincial Biological Resources Investigation Team, the occurrence of yellow leaf blight (tentative name) occurs on alkaline or strong alkaline soil such as Shaanxi, Shanxi and Henan, mainly due to the decrease in the solubility of some trace elements and the non-absorbable state , And some think that the soil lacks effective iron and causes physiological diseases. These valuable experiences deserve our attention in our province to carry out the work of northward migration of bamboos. The introduction of bamboo from the Yancheng area in 1958 in our province has now succeeded in the coastal salt land area in eastern part of China. Some of the forest farms and communes and brigades have closed forests, and some new bamboo forests have survived more and more bamboo shoots. But whether or not normal growth, people have a lot of questions. In order to explore the adaptability of bamboo, seek ways of development and solve the issue of bamboo self-sufficiency in our province, we investigated the soil and stand growth of 15 new and old bamboo introduced points in 1977-1978 and collected the experience of mass cultivation of bamboo In Sheyang Forest Farm, different salinities of soil were selected for afforestation experiment, and the change and growth of soil salinity were observed regularly. Based on the data of two years of investigation and observation, this paper only analyzed the problems of bamboo soil in this area.
