通过对土壤分析资料和相关的调查资料进行统计分析,研究了衡山县耕地地力现状和耕地施肥中存在的问题。结果表明,衡山县的耕地地力可以划分为7个等级,归属高产耕地、中产耕地和低产耕地3个类型,各类型的土养养分差异较大,对于作物产量的贡献率也各不相同。衡山县需要改良的中低产耕地面积和培肥地力的任务较大。在此基础上,提出了耕地地力用养结合的四个基本对策。
Through the statistical analysis of soil analysis data and relevant survey data, the status quo of cultivated land productivity and the problems in cultivated land fertilization in Hengshan County were studied. The results showed that the cultivated land productivity of Hengshan County can be divided into seven grades, belonging to three types of high-yielding cultivated land, middle-yielding cultivated land and low-yielding cultivated land. There is great difference among various types of soil nutrient and contribution to crop yield. Hengshan County need to improve the middle and low yielding arable land and fertilizing the larger the mandate. On this basis, four basic countermeasures were put forward to combine the use of cultivated land with supportiveness.
