遂平县小麦高效施肥区域划分与应用效果的研究

目的]研究县域内不同地域土壤养分含量差异,进行土壤类型和土壤肥力分区,建立小麦施肥指标体系.方法]根据遂平县耕层土壤样品化验结果,结合地貌类型、土壤类型、耕作制度与农业生产水平的相对一致性,把遂平县小麦生产分为高中低3个不同类型区.结果]遂平县耕层土壤养分从东北至西南呈螺旋状下降趋势,东部砂姜黑土区域各项指标明显高于中西部地区的沙壤土地区,而西部部分地区呈现缺磷缺钾态势.结论]该研究有助于提出县域分区高效施肥的意见.

Study of Regional Division of Wheat Production Area in Suiping County and Application Effect of Fertilization

Objective] The research aimed to study the difference of soil nutrient contents in different region of the county territory,partition according the soil types and soil fertility,and establish the fertilization indicator system of the wheat.Method] According to the test results of soil samples in Suiping County,relative consistency with the landform type,soil type,farming system and agricultural production level,wheat production area in Suiping County could be divided into three different types.Result] Nutrient contents in Suiping County soil from northeast to southwest showed spiral downward trend.The indicators of eastern Shajiang black soil region were significantly higher than that in the central and western regions of the sandy land area.The western part of the region showed a lack of phosphorus and potassium.Conclusion] The research was helpful for the proposal of the regionalized fertilization.
