数控温室下红花槭的嫩枝扦插技术

Green-wood Cutting Techniques of Acer rubrum L. in Numerical Control Greenhouse

红花槭为不易扦插成活的树种,其扦插对环境、插穗的木质化程度等条件要求较高。该研究利用温室自动化控制系统,通过温室环境信息与温室决策控制系统的嵌合,实现对空气湿度、温度、光照强度的控制,以提高红花槭的嫩枝扦插成活率。结果表明,红花槭的扦插深度以5 cm生根效果最好。8月下旬,红花槭插穗生根率最高,达82.3%,5月次之。生根效果以基质含水量为65%、80%的处理最高,扦插后期,应适当降低基质水分。红花槭嫩枝以100 mg/LABT1#或200 mg/LNAA浸泡6 h为最佳。试验结果可以直接指导红花槭温室规模化生产。

Red maple（Acer rubrum L.） is a tree species that is not easy to survive cutting. The cutting of redmaple has high requirements for controlled environments, cuttings age and so on. The research was carried outin the greenhouse with automatic control system and device. In the greenhouse, environmental information andgreenhouse controls were embedded. Besides, air humidity, temperature and light intensity were all controlledby the system. Study showed that the cutting depth of 5 cm had the best effect on root growth. Cuttingconducted in late August could achieve 82.3% rooting rate, and the next high survival group was May. Thecultivation groups with 65% and 80% substrate moisture content showed the highest rooting effect, and in thelate period, the moisture content should be cut down to receive better root growth. The semi lignified shoots ofred maple dipped in 100 mg/L ABT1#or 200 mg/L NAA for 6 h showed the best results. The test results mayguide the cutting production of red maple.
