摘要:
为促进秦巴山区核桃林增产增收，在秦巴山区特定气候条件下，通过对比试验，探讨了不同改造措施对核桃林的改造效果，确定最佳的改造时间与措施。结果表明：高接换优是提高秦巴山区低效核桃林经济效益的最佳途径；秦巴山区春季核桃高接换优的最佳时间在3月下旬至4月上旬；接穗应随采随接，接穗髓心应＜1.0 mm，且无病虫害；嫁接方式以插皮舌接成活率最高，嫁接后将接口和接穗用薄膜包裹严实，可使高接成活率达到90%以上；主干放水是影响高接成活的关键因素。
Abstract:
In order to promote the increase of yield and income of walnut forest in Qinba mountain area,in the Qinba Mountains specific climate conditions,through the comparative experiment,the effect of different transformation measures on the transformation of walnut forest was discussed to determine the best transformation time and measures.The result showed that grafting modified was the best way to improve the economic efficiency of low-yield walnut forests in Qinba mountain area; The best time of Qinba Mountain walnut high exchange from late March to early April,spike marrow should be <1.0 mm,no pests,bud full,survival rate could reach 90%; Grafting method to scion spike with a large area of the tongue inserted the highest survival rate; After the grafting and scion agricultural film tightly wrapped,allow head-survival rate of 90%; Trunk turn on the water was a key factor affecting the survival of grafting.
