The yield as well as the quality of the tomato fruit grown on such acidified soil was distinctly lowered as compared with those grown...

Field investigation and field/pot experiments were conducted in the vegetable farm around Hangzhou city, to study the course of acidification of soil, as well as its effect on tomato plant. It was found that the primary cause for the farm soil to become acidified was the heavy applications of physiological acid fertilizers, such as (NH4)2SO4, NH4Cl, K2SO4, etc. in the long run. The yield as well as the quality of the tomato fruit grown on such acidified soil was distinctly lowered as compared with those grown on the normal soil plot. It is suggested that the acidification of vegetable farm soil may be easily prevented by frequent application of limestone powder or refuse manure

通过菜地土壤考查和番茄的田间及盆栽试验,明确了杭州市郊菜地土壤酸化的主因是长期偏施大量生理酸性肥料,特别是硫酸铵.而目前降水中的致酸离子的影响,似乎还不严整.在亩施15kg氮的情况下,硫酸铵处理的土壤pH较对照下降0.59,交换姓酸量增加1.23me/100g土,影响显著;尿素处理的土壤pH下降0.18,交换性酸量增加0.21me/100g土,影响轻微.当土壤pF降至5.35以下时,土壤交换性酸度,特别是交换性铝量剧增,盐基饱和度迅速下降,此时番茄根系发育差,产量和品质均明显下降.酸化的菜地土壤,其交换性酸含量虽高,但以交换性H~+为主.施用城市生活垃圾肥或石灰石粉即可校正土壤酸度.

According to the Chinese Soil Taxonomy Classification (the second edition), based on the 64 soil profiles data collected in Jianfengliug region, Hainan Island, selecting 5 diagnostic characteristics (OM,pH,BS, Al, ECEC) of the soils, using the methods of both principal component analysis and discriminatory analysis, the soil types were classified into 7 subgroups as follows: humic yellow soil, surface-gley yellow soil(belonging to yellow soil great group); typical lateritic yellow soil(belonging to lateritic...

According to the Chinese Soil Taxonomy Classification (the second edition), based on the 64 soil profiles data collected in Jianfengliug region, Hainan Island, selecting 5 diagnostic characteristics (OM,pH,BS, Al, ECEC) of the soils, using the methods of both principal component analysis and discriminatory analysis, the soil types were classified into 7 subgroups as follows: humic yellow soil, surface-gley yellow soil(belonging to yellow soil great group); typical lateritic yellow soil(belonging to lateritic yellow soil great group); humic latosol, moist latosol and rich-base latosol(belonging to latosol great group) and dry red earth great group. The total accuracy of discrimination is more than 75.6 %. The equations were established through the principal component analysis. They defined the eigenvalues, delimitation index and the figure of the principal component scattering points with discriminatory boundaries of soil classification. The variation of the types both in the boundaries of soil classification and the characteristics of the soils are of significant difference.

利用海南岛尖峰岭地区现有的64个土壤剖面分析资料,试用新拟中国土壤系统分类(二稿)标准,选择土壤腐殖质、pH、盐基饱和度、交换性铝及有效阳离子交换量等诊断特性,应用主组元和判别分析方法,将该地区的土壤区分为7个亚类4个土类,总的判别正确率达75.6%。为区域性土壤数量化系统分类的有益尝试,较之原有发生分类有所发展。
