Construction of High-standard Farmland Based on the Present Situation of Soil Fertility and Fertilizer Improvement Countermeas-ures—Taking Hui'an Street in Lankao County as an Example
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 farm-land 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 develop-ment 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.
