多年来,一些地方由于夏玉米种植方式存在一些误区,造成玉米产量一直徘徊不前,为了促进夏玉米增产增收,为此提出如下四措施。改单一施肥为配方施肥长期以来,农民在玉米施肥上习惯施用氮素化肥,忽视氮磷钾和微肥的作用,造成养分单一,增产效果不理想,多项试验结果表明,在同样适用氮素化肥的情况下,每667米2增施25、50、75千克磷肥,每千克磷肥分别增产玉米1.90、1.72、1.45千克;每667米2
Over the years, some areas have some misunderstandings due to the summer corn planting methods, resulting in maize production has been stagnant, in order to promote summer maize yield increase, to this end, the following four measures. A single fertilization as a formula fertilization For a long time, farmers are accustomed to using nitrogen fertilizer on corn fertilization, ignoring the role of nitrogen, phosphorus and potassium and trace fertilizers, resulting in a single nutrient, the yield is not ideal, a number of test results show that the same application of nitrogen In the case of chemical fertilizers, 25,50 and 75 kg of phosphate fertilizer are applied per 667 m 2, and the yield of maize is 1.90, 1.72 and 1.45 kg per kg of phosphate fertilizer respectively; for every 667 m 2
