靖西县田七种植区土壤肥力特征的差异性分析

Evaluation of Soil Fertility Characteristic of Panax notoginseng Planting Area in Jingxi County

对靖西县3个不同区Ⅱ田七种植区（新甲乡、化垌乡、武平乡）的9个采样点进行土壤肥力状况分析,结果表明院靖西县田七种植区土壤肥力指标有一定的差异性,田七种植区土壤成酸性反应（p H值4.69~5.16）,有机质、速效钾从中等到丰富不等,速效磷（52.37~89.52mg/kg）均呈很丰富的状态,碱解氮分布不均（33.6~92.4 mg/kg）,由较缺到中等不等。就不同区Ⅱ而言,3个区Ⅱ有一定的差异,但彼此间差异不明显,总体来讲,新甲乡的综合肥力强于化垌乡,武平乡稍差。

The soil fertility condition in 9 acquisition points of 3 different Panax notoginseng cultivation areas （Xinjia Township, Huatong Township and Wupin Township） in Jingxi County were analyzed.The results showed that there existed certain different index soil fertility in Panax notoginseng cultivation areas of Jingxi County.The indexes of Acid reflection （pH value） of Panax notoginseng euhivation were from 4.69 to 5.16.The indexes of organic material and available potassium were from intermediate to abundance.Available phosphorous was in a abundance condition （52.37 -89.52 mg/kg）. The distribution of available nitrogen was inhomogeneous, from shortage to intermediate （33.6-92.4 mg/kg）.In different regions, 3 districts existed not really obvious differences.On the whole, the comprehensive soil fertility of Xinjia Township was better than that of Huatong Township,that of Wupin Township was a bit worse.
