近年来,河南科学院的科技工作者,在进行全省土壤普查的基础上,因地制宜配制成多种复合微肥,在小麦、玉米、棉花、西瓜、花生、柑桔等作物上进行了大量试验,取得了明显效果.最近,他们又与开封县合作,在二十多个乡推广小麦微肥拌种近六万亩. 植物同人体一样,在其生长发育中需要铁、锌、锰、钼、镍、硼等元素,这些元素同植物体中的碳、氢、氧、氮、磷、钾相比,含量较少,仅占植物体的万分之几或十万分之几,缺乏时,稍加补充,则可以起到明显的增产效果.故此,人们把它们做成微量元素肥料.简称
In recent years, scientists from Henan Academy of Sciences conducted large-scale experiments on crops such as wheat, corn, cotton, watermelon, peanut and citrus on the basis of conducting soil census of the province and formulating a variety of compound micronutrients according to local conditions. Recently, they also cooperated with Kaifeng County to popularize nearly 60,000 mu of wheat micronutrient fertilizer in more than 20 townships. Like plants, plants need iron, zinc, manganese, molybdenum, Nickel, boron and other elements, these elements with plants in the carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium content is less, accounting for only a few ten thousandths of the plant body or a few ten thousandths, the lack of time Add replenishment, you can play a significant yield-increase effect. Therefore, people make them trace elements of fertilizer.
