调查试验研究表明：土块瘠薄，偏施氮、磷化肥，不施钾肥，播期偏晚，密度78000棵／hm2以上，种植生育期长的晚熟品种等都使夏玉米空秆增多。增施有机肥，平衡施用氮、磷、钾化肥，适期早播，合理密植，选用郑单14、掖单19等中熟品种是预防夏玉米空秆的有效措施。
The investigation and research showed that: the soil block was barren, partial nitrogen fertilizer, phosphorus fertilizer, no potassium fertilizer, late sowing date, density more than 78000 trees / hm2, planting late maturing varieties and so on all increased the summer maize stalks. The application of organic fertilizer, balanced application of N, P and K fertilizers, early sowing of suitable period and rational close planting were the effective measures to prevent summer corn blank stalks by selecting medium maturing varieties such as Zhengdan 14 and Yedan 19.
