Evaluation of potential for exploiting arable land in low hilly red soil region in Lanxi based on remote sensing and GIS;

The course of developing for peanut planting indicates that the sustainable high yield for peanut encounters four obstacles in low-hilly red soil region of south China in new century: They are long-term culture without rotation; degrading of peanut breed; drought hazard to crops during mid-summer and autumn and the improper dosage and method of fertilization.

Based on field observation in summer,the paper analyzed the variable of water- retaining capacity of 1 m soil horizen and soil water consumption in hot summer days on paulownia-tea system on low hilly red soil.

This Paper discussed the significance, distribution, countermeasures and pattern of Ginkgo-growing in southern red soil hillock, and analysed its invest and yield.
