锰是作物生长发育所必需的营养元素之一,它能促进作物体内氧化还原过程和光合作用。锰素缺乏,将会导致作物产量低、品质差。目前,我省大部分土壤缺锰,特别是黑龙港地区的麦田,由于受旱、碱条件的影响,使土壤中有效锰含量降低。 我站1989—1992年连续进行了小麦施用硫酸锰试验,结果是:施用硫酸锰作基肥、拌种、喷施 Manganese is one of the necessary nutrients for crop growth and development, which can promote redox processes and photosynthesis in crops. Lack of manganese will result in low crop yields and poor quality. At present, most of the soil in our province is deficient in manganese, especially in the wheat fields in Heilonggang. Due to the drought and alkali conditions, the effective manganese content in the soil is reduced. I was stationed in 1989-1992 consecutive wheat application of manganese sulfate test, the result is: the application of manganese sulfate as a base fertilizer, seed dressing, spraying
