ESSENTIALS ON THE REGIONS OF RED SOILS AND YELLOW SOILS UTILIZATION AND IMPROVEMENT IN FUJIAN

Dept.of Soil and Agrochemistry,FAC According to the requirements and grading standards of zoning red soilsand yellow soils utilization and improvement,the whole land of Fujian isdivided into two soil zones,four soil regions and eight soil groups.Theyare arranged as follows:Ⅰ.Red soils and yellow soils zone of central subtropics.Ⅰ_1 Mountainous red soils,yellow soils and paddy soils,as forest,crop and tea regions of Wuyi-Daiyun Shan Shan-Jiufeng Shan.I_1(1) Mountainous red soils,yellow soils and yellow paddy soils,improved low productive soils and erosion defence groups at medium moun-tains of northeastern Fujian.Ⅰ_1(2) Mountainous yellow soils,red soils and cold nondrained soils,improved low productive soils and well manured groups at medium moun-tains of northwestern Fujian.I_1(3) Red soils,cold nondrained soils and fluvoaquic paddy soils,improved low productive soils,well manured and erosion defence groupsat low mountains and basin between mountains of northern Fujian.Ⅰ_1(4) Red soils,mountainous yellow soils and yellow paddy soils,integrated improved groups at medium mountains of central Fujian.Ⅰ_1(5) Red soils,mountainous yellow soils,purple soils and yellowpaddy soils,improved low productive soils and soil conservation groups atvalleys basin and medium mountains of southwestern Fujian.Ⅰ_2 Red soils,paddy soils and solonchak,as crop,tea regions of thehill and plain eastern seacoast of Fujian and Zhejiang.Ⅰ_2(1) Red soils,dark paddy soils,yellow paddy soils and desalini-zed paddy soils,drought control,well manured and soil conservation groupsat hill and plain of Fujian eastern seacost.Ⅱ.Lateritic red soils-red soils zone of southern subtropics.Ⅱ_1 Lateritic red soils,red soils and paddy soils,as crop,cash crops and tropical crops regions of southeastern seacoast.Ⅱ_1(1) Lateritic red soils,dark paddy soils,desalinized paddy soilsand red sandy soils,soil conservation,well manure and drought controlgroups at hills and plain of southeastern Fujian.Ⅱ_2 Lateritic red soils,red soils and paddy soils,as crop,forestry andcash crops regions at low mountains and hills of Fujian and Guangdong.Ⅱ_2(1) Lateritic red soils,red soils,red sandy soils and sandy flu-voaquic paddy soils,erosion defence and drought defence groups at lowmountains and hills of southeastern Fujian.
