据调查,建始县土壤酸化需治理的耕地面积达34万亩,为加快推进土壤环境保护与土壤改良工作,达到“土更净”的建设目标,促进生态文明建设和农业可持续发展,本文对土壤环境状况进行了分析并提出了具体措施。1现状分析1.1土壤酸化现状。建始县耕地土壤p H值较低,土壤酸化严重。全县耕地p H值平均为5.2(其中旱地p H值平均为5.1、水田p H值平均为5.8)。其中p H值低于4.5的极酸性耕地土壤16万亩,占总面积的30.7%,p H值在4.6~5.5的强
According to the survey, the soil acidification in Jianshi County needs to be managed with an area of 340,000 mu of cultivated land. In order to speed up soil environmental protection and soil improvement and achieve the goal of “making the soil more clean” and promoting the construction of ecological civilization and sustainable development of agriculture, This paper analyzes the status of soil environment and puts forward specific measures. 1 Status Analysis 1.1 The status of soil acidification. Soil pH in cultivated land of Jianshi County is low, soil acidification is serious. The average p H value of cultivated land in the entire county was 5.2 (including an average p H value of 5.1 in dryland and an average p H value of 5.8 in paddy field). Among them, 160,000 mu of extremely acidic cultivated soils with p H values less than 4.5, accounting for 30.7% of the total area, with p H values between 4.6 and 5.5
