摘要
在小麦返青期、拔节期、抽穗期和灌浆期分别喷施1次微量元素水溶肥料,每次用量100g/亩。与清水对照比较,每亩增产35.43公斤,增产率为7.1%;与空白对照比较,每亩增产37.47公斤,增产率为7.5%。对不同喷施次数进行了效果比较,结果表明,微量元素水溶肥料不是喷施越多越好,而是应该科学施用。
The water-soluble trace element fertilizer was spayed once on wheat in seedling establishment period,shooting stage,heading stage and filling stages,and the every time dosage is 100g/667m2.Compared with water control,the yield increase of wheat is 35.43kg,and the increase rate is 7.1%.Compared with blank control,the yield increase is 37.47kg,and the increase rate is 7.5%.Compared with different number of spraying,the results show that the water-soluble trace element fertilizer is not spraying the much the better,but rather scientific application.
