- 摘要:
- 云南植物资源丰富,在不同气候区域,当地群众发掘可食用野生森林蔬菜品种繁多,为有效利用和开发森林蔬菜品种,逐步开展具有开发价值的森林蔬菜品种繁育试验。以野生刺通草2 年生枝条为插穗,开展不同扦插基质、植物生根混合剂、浸泡时间及扦插季节试验,探索其不同处理对刺通草平均生根量、生根长度及生根率的影响。结果表明,最佳处理基质为复合基质,体积配比为腐殖土∶山沙∶泥碳土∶蛭石∶发酵秸秆粉=3∶3∶2∶1∶1,植物生根混合剂质量配比为0002%α-萘乙酸钠∶0.02%萘乙酸酰胺∶0.01%硫脲=1∶1∶1,选用2 年生刺通草枝条,在植物生根混合剂浸泡 5 min后扦插,扦插50 d后刺通草插穗平均生根数量达5.87条、生根长度至8.28 cm、生根率为80.16%。
- Abstract:
- Yunnan is rich in plant resources, there are variety of edible wild forest vegetables for local people in different climatic zones. In order to utilize and develop the forest vegetable resource effectively, breeding experiments of forest vegetable varieties should be carried out gradually. Taking perennial tree shoots (two-year) of wild Trevesia palmata as cuttings, comparative trails of cutting survival rate were carried out in terms of composite substrate, mixed plant rooting agents, soaking time, and cutting seasons. It aims to explore the effects of different treatments on averaging rooting, rooting length and rooting rate of Trevesia palmata. The analysis of cutting trials showed that the best treatment was the composite substrate consists of humus soils, mountain sand, peat soil, vermiculite, and sermented shredded stalk, the volume ratio was 3∶3∶2∶1∶1. The mixed rooting agents include 0.002% α-Naphthylacetic acid, 0.002% naphthalene acetamide, and 0.001% sulfocarbamide, the ratio was 1∶1∶1. After soaking in the mixed rooting agents for 5 minutes, the perennial tree shoots (two-year) of wild Trevesia palmata were cutting propagated. After 50 days of cutting propagation, the average rooting number reaches 5.87, the rooting length was 8.28 cm, and the rooting rate was 80.16%.
