摘 要:以河南省兰考县惠安街道“万亩高标准农田”为例,利用统计、调查等方法开展农田土壤养分状况评价及关键提升对策分析。结果表明,兰考县高标准农田示范区各村镇耕层土壤养分含量存在明显差异,普遍存在土壤养分含量偏低,有机质不足,氮、磷、钾缺乏,盐分含量较高等现象,需要对标关键区域实施土壤肥力提升举措。现有发展水平下,高标准农田建设以及种植结构的调整等政策措施对村镇耕层土壤养分含量的提高具有一定的作用。从测土配方、改良培肥措施以及调整种植结构等方面提出了相应对策,以期为高标准农田质量提升以及资源高效利用提供借鉴参考。Taking ten-thousand mu high-standard farmland in Hui'an Street,Lankao County,Henan Province as an example,the evaluation of soil nutrients and the analysis of key improvement countermeasures were carried out by the methods of statistics and investigation.The results showed that there were obvious differences of soil nutrient content in the topsoil layer among the villages and towns in the high-standard farmland demonstration zone of Lankao County.There were generally low soil nutrient content,lack of organic matter,lack of nitrogen,phosphorus and potassium,and high salt content.It was necessary to implement soil fertility improvement measures in the key areas.At the current development level,the policy measures such as the construction of high-standard farmland and the adjustment of planting structure had a certain effect on the improvement of soil nutrient content in rural areas.Some corresponding countermeasures were put forward from the aspects of soil testing formula,improved fertilizer cultivation measures and planting structure's adjustment,so as to provide references for the improvement of high standard farmland quality and efficient utilization of resources.
