平欧杂种榛与中草药白薇间种模式研究

Study on the Interplanting Model Between Corylus heterophylla×C.arellana and Cynanchum atratum

为探索辽北山区林药间种经营模式,通过平欧杂种榛一个生长周期(8~12年)间种中草药白薇的试验结果分析,平欧杂种榛间种中草药白薇模式是非常值得推广的,除了可以解决平欧杂种榛幼龄期无效益的问题,还可以提供优质的中草药白薇种子和药根。通过试验比对,中草药白薇在平欧杂种榛幼龄期表现要比盛果期和衰败期好,无论从保存率、苗高、根茎鲜重和种子的产量都有明显效果。同时开展了中草药白薇与平欧杂种榛间种打孔穴植覆膜技术,施肥技术以及病虫害防治技术的研究。结果表明,白薇覆膜打孔种植技术应大面积推广。施肥对中草药的生长指标、产量有明显影响,以有机肥效果最好。白薇蚜虫虫害及根腐病使用多菌灵可湿性粉500~1000倍液(50%)。

In order to explore the management model of interplanting forest medicines in northern Liaoning,through the analysis of the experimental results of the interplanting of Cynanchum atratum for one growth cycle(8-12 years)of Corylus heterophylla×C.arellana,the model is very worthy of promotion.In addition to solving the problem of ineffectiveness in the juvenile period of Corylus heterophylla×C.arellana,it can also provide high-quality Cynanchum atratum seeds and roots.Through experimental comparison,the performance of Cynanchum atratum in the juvenile stage of Corylus heterophylla×C.arellana is better than the full fruit stage and the decay stage.It has obvious effects in terms of preservation rate,seedling height,fresh root weight and seed yield.At the same time,the research on the technology of perforating hole planting and covering film,fertilization technology and pest control technology of Cynanchum atratum and Corylus heterophylla×C.arellana were carried out.The results show that Cynanchum atratum mulching and perforating planting technology should be popularized in a large area.Fertilization had obvious effect on the growth index and yield of Cynanchum atratum,and organic fertilizer had the best effect.Carbendazim wet-powder was used in 500~1000 times solution(50%)for aphid pests and root rot of Cynanchum atratum.
