一、M832的研制与成份作物生长发育需要许多营养元素,除了N、P、K三大元素和Ca、Mg、S等中量元素外,还需要B、Mn、Mo、Zn、Cu、Fe等微量元素,大多数微量元素是植物体内酶或辅酶的组成成分。其生理功能是独特的,专一性很强。因此,相互间不能代替,大量元素不能代替微量元素,同样,微量元素也不能代替大量元素。各种营养元素决不是单独发挥作用,而是互相联系、互相促进的,所以营养元素之间应有一定的比例,以保持平 First, M832 development and composition Crop growth and development require many nutrients, in addition to N, P, K and Ca, Mg, S and other elements in the middle, but also need B, Mn, Mo, Zn, Cu, Fe, etc. Trace elements, most trace elements are components of plant enzymes or coenzymes. Its physiological function is unique and highly specific. Therefore, each other can not be replaced, a large number of elements can not replace trace elements, the same, trace elements can not replace a large number of elements. A variety of nutritional elements are by no means independent, but interrelated and mutually reinforcing, so there should be a certain proportion of nutrients in order to maintain a flat
