摘要
在基肥基础上于拔节期、抽雄期和灌浆期对玉米喷施含氮、磷、钾、钙、镁、锌、硼、锰、铁、钼、铜全营养型液体水溶肥料,能较好地增加产量和经济效益.试验结果表明:与清水和空白对照比较,喷施水溶肥料后每公顷增产分别为765 kg、1 102.5 kg,增产率分别为8.90％、13.35％,每公顷增加纯收益分别为1 948.5元、2 430元;玉米蛋白质和碳水化合物含量也略有提高.
Abstract
On the basis of basic fertilizer,spraying nitrogen,phosphorus,potassium,calcium,magnesium,zinc,bo-ron,manganese,iron,molybdenum and copper nutrient liquid soluble fertilizer on maize at jointing stage,heading stage and filling stage can better increase yield and economic benefits.The results showed that compared with water and blank control,the yield per hectare increased by 765 kg and 1 102.5 kg,the yield increase rate was 8.90％and 13.35％,and the net income per hectare increased by 1 948.5 yuan and 2 430 yuan respectively.The protein and carbo-hydrate content of corn also increased slightly.
