黄壤是我省主要土壤类型。全省耕地面积中由黄壤开垦而成的约占41.8％近1,200万亩。但是,关于黄壤腐殖质特性及其与成土条件、耕作措施之间的关系,至今很少有人研究。为了合理开发黄壤资源,不断提高黄壤肥力,我们于1980年及1981年,分别采集了不同母质、不同海拔高度及不同利用类型的黄壤对其腐殖含量、组成及有机质的碳氮比值、光密度等特性进行了分析研究。现将初步结果整理报告如下:
Yellow soil is the main type of soil in our province. About 41.8% of the cultivated area of the province is reclaimed from yellow soil, accounting for nearly 12 million mu. However, few studies have been conducted on the characteristics of humus in yellow soil and their relationship to soil conditions and tillage practices. In order to rationally develop yellow soil resources and improve the fertility of yellow soil, we collected the yellow soil with different parent materials, different altitudes and different types of utilization in 1980 and 1981, respectively. The results showed that the humus content, composition and carbon / nitrogen ratio of organic matter, And other characteristics of the analysis. The preliminary results are now summarized as follows:
