Abstract: Effect of spraying trace element fertilizer on microelement absorbency of little rapeThe result showed that absorptivity was improved as B、Zn、Fe、Mn and Ca fertilizer wasapplied respectively under reasonable concentration,both trace elements content and theamount that can be taken away increased.The treatment of Zn,B and Mn fertilizer were themost remarkable.The Zn content and its amount of being taken away every one rape had beenincreased by 419.02%and 512.51%after spraying Zn fertilizer.When we sprayed B fertilizeron little rape,the content and amount of taking away of B also had been enhanced by232.91%and 342.94%.Similarly,the Mn content and its taking away amount had beenimproved by 74.14%and 119.49%.But when we sprayed Fe or Ca fertilizer,it changed alittle.
