江苏省淮北地区属黄淮海平原。本区花碱土分布最广,成为主要的低产因素之一。积极进行花碱土综合治理,变低产为高产,对促进全省农业持续均衡增产,加速建成淮北新商品粮基地,具有重大意义。为此,我们整理了1957年以来有关的科研成果。本文以阐述花碱土的发生特性为中心,并对其形成演变进行分析探讨。 Huaibei Province, Jiangsu Province is a Huang-Huai-Hai Plain. The most widely distributed in this area of ​​alkaloids, a major low-yielding factors. It is of great significance to actively carry out the comprehensive control of the spent alkaline soil and to change the low-yielding high-yielding products, so as to promote the continuous and balanced increase of the agriculture in the province and speed up the construction of the new commodity grain base in Huaibei. To this end, we have compiled the relevant scientific research since 1957. In this paper, we elaborate on the occurrence characteristics of alkaline earth and analyze its formation and evolution.
