鹤峰县测土配方施肥指标体系研究

Research on the Index System of Soil Testing and Formulated Fertilization in Hefeng County

为了建立适宜鹤峰县耕地土壤肥力现状和产业发展特点的作物施肥模式,依据国家测土配方施肥技术规范,平均每4 hm2采集1个耕地土壤样本,测试常规5项及中、微量元素,对测试数据进行分析,参照鹤峰县第二次土壤普查结果和农民施肥习惯,初步建立了鹤峰县耕地养分丰缺和主要作物施肥两大指标体系,构建了适宜鹤峰县耕地土壤和农业产业发展的测土配方施肥技术路线,设计完成了16∶8∶16、14∶8∶18、14∶12∶14和15∶15∶15共4个鹤峰县主要作物施肥配方.

In order to establish the mode of crop fertilization suitable for the fertility of soil of current situation of Hefeng County and specialty of its industry,a sample of arable soil for each 4 hm2 is taken to have 5 regular tests and to test trace elements,according to the national regulations on the technique to measure the soil formulation to apply fertilizer.Through analyzing the test data and consulting the second result of soil survey and local farmer＇s traditional fertilization,two main indexes systems,deficiency of nutrients in arable land and main crop fertilization,have been established,and technique line of measuring the soil formulation to apply fertilizer suitable for arable soil and the agricultural industry has been structured,which includes 4 fertilizer recommendations for Hefeng County 16∶8∶16,14∶8∶18,14∶12∶14 and 15∶15∶15.
