摘要
春小麦是宁夏灌区的主要粮食作物,化肥和农药是影响小麦产量和品质的关键因素,其过量投入直接影响春小麦的产量和品质,同时造成产地环境污染等问题。因此,通过评价灌区小麦产区土壤肥力,依据小麦养分需求量,结合灌区春小麦施肥和施药的实际情况,总结提出了宁夏灌区春小麦化肥农药减施增效技术规程。
spring wheat is the main grain crop in Ningxia irrigation area.Chemical fertilizer and pesticide are the key factors affecting the yield and quality of spring wheat,at the same time caused environmental pollution and other problems.Therefore,through the evaluation of soil fertility in the irrigated area,according to the nutrient demand of wheat and the actual situation of fertilization and pesticide application of spring wheat in the irrigated area,the technical regulations of reducing application of chemical fertilizer and pesticide and increasing effect on spring wheat in Ningxia irrigation area were summarized and put forward.
