在作物生产中,所有营养元素是一个统一的植物营养体系,它们之间是相辅相成的,而且是互相制约的.作物一生中,不仅需要从外界吸收不同种类的养分,而且需要不同的养分比例,如果土壤中营养元素供应平衡,作物可按比例吸收利用,产量高品质好,如果供应不平衡,则产量低品质差.如果某一元素过多,则产生奢侈吸收,甚至引起代谢紊乱.为了使作物能正常的生长发育,并获得较高的产量及较优的产品品质,如何根据各地土壤中的养分状况及作物需肥特性,进行平衡施肥是非常重要的.这里所指的平衡施肥主要是指采取不同的养分配合施用,以调节土壤中养分的平衡,
In crop production, all nutrient elements are a unified system of plant nutrition, which are mutually reinforcing and mutually restraining.During crop life, not only need to absorb different kinds of nutrients from the outside world, but also need different nutrient proportion, If the supply of nutrients in the soil balance, the crop can be absorbed in proportion, high yield and good quality, if the supply is not balanced, the yield is poor quality, if an element is too much, then produce extravagant absorption, and even cause metabolic disorders.In order to make Crops can grow normally, and get higher yield and better product quality, how to balance the fertilization according to the nutrient status of the soil in the soil and the characteristics of the crop needs to be very important .This refers to the balanced fertilization is mainly Refers to the use of different nutrients with the application to regulate the balance of nutrients in the soil,
