玉米生产中,配方施肥可以提高肥效,增加效益,是一个发展趋势。近年,我县在这方面进行了探索。 配方要根据当地的土壤养分状况,选择最佳配方。我县地处燕山丘陵区,经过取样分析,有89％的土壤缺磷,有87％的土壤缺钾,有80％的土壤缺锌。针对这种状况,我们在玉米集中产区安排多点增施钾锌肥的实验。结果表明,亩施2公斤 In corn production, formula fertilizer can improve fertilizer efficiency and increase benefit, which is a development trend. In recent years, my county in this area were explored. The recipe should be based on local soil nutrient status, choose the best formula. County is located in Yanshan hilly area, after sampling analysis, 89% of the soil phosphorus deficiency, 87% of the soil potassium deficiency, 80% of the soil zinc deficiency. In response to this situation, we have arranged more experiments on increasing potassium and zinc fertilizers in the corn-producing areas. The results show that 2 kg of Mushi
