    摘要:

    我国长江以南的亚热带地区,多红壤分布,其中以第四纪红色粘土发育的红壤最为常见,均为主要垦殖对象。有的红壤垦殖利用情况良好,开垦后,土壤性质逐渐变好,得到稳定耕种;但是有的红壤利用很差,开垦两三年后,作物产量减低;有的红壤甚至连马尾松都长不好。红壤肥力的差别,显然受到红壤本身性状的影响,这些不同的土壤性状只有从土壤基层分类单元,才可区别出来。本文拟根据作者等在浙江金衡盆地九攀农中-带土壤详测所获得的部分结果,对本地区红壤的特性及其基层分类问题,作初步讨论。

    Abstract:

    The present paper deals with further classifying the soil basic types of red earth developed from the red clay materials of Quaternary era in Kinhwa basin,Chechiang Province.In this region the red earth lies on the gentlely rolling to undulating topography about 8 to 50 meters above the main river course.Most of the soils are covered under shrubs and grasses.Owing to the variation of soil properties,the capability of utilization of these soils is quite different.Some of them become more fertile and give good harvests after cultivation;but some of them lose their fertility due to severe erosion after successive plantation.Twelve basic types of red earth are classified on the basisof the following variations:1.Variation in parent materials.
