柿树嫁接技术试验研究

The Experimental Study on the Skills of Persimmon Graft

针对柿树嫁接难的问题,从解决砧木“伤流”问题的不同处理、接穗粗度、接穗部位、嫁接时期、嫁接方法以及接穗的贮藏时间等方面进行了为期4年的试验研究。结果表明:柿树嫁接以4月中旬至5月上旬进行为好,选取粗度在1.51～2.40cm之间的中部枝段作接穗,采用舌状芽接法嫁接,最好随采随接,在嫁接时还应注意在接口以下削一长约3cm,深达木质部的舌状皮进行“放水”。通过此法,可使柿树嫁接成活率达到85％以上。

Through the four years' experimental study on the scion thickness, the scion location, grafting time, graft skills, and the storage of the scion etc. the result shows that the proper persimmon graft time should be from the middle ten-days of April to the first ten-days of May. Take the middle part of the scion in the thickness between 1. 51cm to 2. 40cm and the ligulae budding should be done soon after its cut. In order to avoid the too much persimmon juice running out from the cut, another cut under the grafting cut is the one to let it out. Thus, the survival rate can reach 85% or more.
