冠县地处鲁西黄泛平原,耕地面积7.88万hm2,经多年的地力培肥和沟渠、机井等农田基本生产设施配套建设,土壤肥力和土地产出能力有所提高。冠县是全国粮食生产先进县,冬小麦常年种植面积近5.9万hm2,平均单产约6.45t/hm2,总产量稳定在38万t左右。自2008年冠县开始实施国家测土配方施肥项目以来,配方施肥技术推广工作逐步深入,农民科学施肥技术水平有所提高,但农民盲目施肥还是比较严重,主要表现在很多农户长期过量施用磷酸
Guanxian County is located in the Yellow River plain of Luxi County, with an area of 78,800 hm2 of cultivated land. After many years of fertilization by soil fertility and construction of basic production facilities such as ditches and machine wells, soil fertility and land productivity have been raised. Guanxian County is an advanced county in food production in the country. The annual area of winter wheat planting is nearly 59,000 hm2, with an average yield of 6.45t / hm2 and a total output of about 380,000 t. Since 2008, Guanxian County started to implement the project of soil testing and formula fertilization. Since then, the popularization of formula fertilization technology has been gradually deepened and the level of science and technology of fertilization has been improved. However, farmers blindly fertilizing is still more serious, mainly due to long-term excessive application of phosphoric acid
