摘　　要：Ⅰ. INTRODUCTION Being a trace element, boron is very important for the growth of crops, especially for rape, cotton, beet, fruit trees and peanut, and there are many reports about it at home and abroad. The instruments and methods for determining boron are many, but they are not very satisfactory. It is difficult for atomic absorption spectrophotometer to measure boron, so N₂O mixed up with C₂H₂ or with H₂ should be used as a fuel gas for atomization
