近年来,不少农民因忙于其他产业,对作物追肥过于简单,较大程度上影响了作物产量。泗洪县农技人员通过对五种常见作物实际试验与对照分析表明,对作物适期适量追肥,才能更好地满足作物生长对肥料的需求,提高作物的产量水平。一、小麦最佳追肥期小麦应在三叶期实行追肥,一般每公顷追施硝酸铵195～270kg或尿素135～180kg。小麦后期由于根系从土壤中吸收营养的能力减弱,故应在抽穗开
In recent years, many peasants have been too simplistic in their pursuit of top-dressing on crops because of their busyness in other industries, which has, to a large extent, affected their crop yields. Through the practical tests and comparison analysis of five common crops, agricultural workers in Sihong County showed that proper crop top-dressing could meet the demand of fertilizer for crop growth and increase the yield of crops. First wheat topsoil Wheat should be implemented in the three-leaf top dressing, ammonium hector per hectare topdressing 195 ~ 270kg or urea 135 ~ 180kg. Late wheat due to the ability to absorb nutrients from the soil weakened, it should be heading to open
