铁改泡嫁接成活率影响因素的试验分析

铁改泡是发展核桃产业的一个重要途径,采用多因素方差分析和多重比较进行不同地点、环境、时间和方法对铁改泡嫁接成活率的影响比较试验.结果表明,铁改泡嫁接应选择在立春节令后的二月中旬至三月上、中旬芽萌动期(砧木萌动而接穗尚未萌动)进行为最适宜,采用插皮接和切接嫁接的成活率较高,阳坡及半阳坡的嫁接成活率比阴坡高.

Affecting Factors Test Analysis of Survival Rate for j.sigillataGrafting

j. sigillatagrafting is an important way for the development of walnut industry. Muhi-factor va- riance analysis and multiple comparisons for different locations, environment, time and method were used for comparison test of survival rate of j. sigillatagrafting. The results show that j. sigillatagrafting should choose to make in the most appropriate after the occasion of spring begins in mid-February to mid-March when the buds sprout （rootstock sprout and scion not yet）. Using bark and cut grafting can have the higher survival rate. The survival rate is also higher when the grafting is taken on sunny and semi-sunny slopes.
