我国农业有着悠久的历史,我们的祖先在长期生产实践中,很早就懂得,利用不同科属果树相互嫁接,可以改进果树的品质,提高产量。在明代俞宗本《种树书》中已有很多种间、属间和科间的嫁接的记述。如:“梅接桃则脆,桃接杏则大”(种间嫁接)、“柑桔橙等于根棘接者易活”(属间嫁接)、“桑上接梅,梅则不酸”(科间嫁接)等等。 Our country’s agriculture has a long history. In our long-term production practice, our ancestors knew very early that using different branches of fruit trees to graft each other can improve the quality of the fruit trees and increase the output. In the Ming Dynasty Yuzong Ben “tree book” has many kinds of inter-genus and inter-division of the graft description. Such as: “plum then peach crisp peach then apricot is big” (interspecific grafting), “citrus orange is equal to root spike accessist easy living” (genus grafting), “Mulberry then plum, plum is not acid” (Inter-section grafting) and so on.
