土壤矿质元素缺乏或不足引起的植株营养缺乏,会影响植株的生长发育。任何一种必需的矿质元素的缺少都会引起特有的生理病征。但不同植物的表现不一定相同,缺乏元素的程度不同,表现程度也不同,最后都会影响作物的产量和品质。氮、磷、钾三要素植物需要量较大,但有的土壤会缺乏某种元素,致使作物造成减产。本文通过氮、
Soil mineral elements lack of or lack of plant nutrition caused by lack of, will affect the plant growth and development. The lack of any one of the necessary mineral elements causes specific physiological signs. However, the performance of different plants is not necessarily the same, the lack of elements of different levels of performance are also different, and ultimately will affect the crop yield and quality. Three elements of nitrogen, phosphorus and potassium plant needs larger, but some of the soil will be a lack of certain elements, resulting in crop production. In this paper, nitrogen,
