植物除了需要水分以外,还需要一些元素,这些元素大多来自土壤,因此叫矿质元素。农业生产中给作物施肥就是给土壤补充这些元素,以满足作物增产的需要。植物必需的矿质元素及其生理功能植物体内含有很多化合物和各种离子。这些化合物或离子都是由不同的化学元素所组成的,它们的功能各不相同。一、植物体内的元素和必需元素。目前已知的化学元素几乎在植物体内都有发现。根据其含
In addition to the need for water plants, but also need some elements, most of these elements from the soil, so called mineral elements. Fertilizing crops in agricultural production is to replenish the soil with these elements to meet the needs of increased crop production. Plant essential mineral elements and their physiological functions Plant contains many compounds and various ions. These compounds or ions are composed of different chemical elements, their functions vary. First, the plant’s elements and essential elements. Currently known chemical elements are found in almost all plants. According to its containing
