珍贵树种红椎优质苗木高效繁育技术

Efficient Breeding Technology of High-quality Seedlings of Red Vertebrae of Precious Tree Species

红椎在近年来国土绿化中需求量较大。通过总结其扦插和播种苗期管理等一系列技术,近年来对相关技术进行了改进。红椎种子采摘采取室外沙藏处理,一层薄膜、一层稻草、25℃的温水保湿效果最佳。红椎扦插在每年的6月效果最佳,相对湿度90~95%,温度保证在20℃~35℃。采用事先分级的方法,一年生苗木的合格出圃率从70%提高到80%以上。红椎高效繁育技术体系可以为后续的红椎苗木的生产提供相关参考。

C.hystrix have a large demand in land greening in recent years.By summarizing a series of techniques such as cutting and sowing seedling man agement,the related technologies have been improved in recent years.The see ds of C.hystrix were picked by outdoor sand storage,and one layer of film,o ne layer of straw and 25℃warm water had the best moisturizing effect.The cutting effect of C.hystrix is the best in June every year,with relative humidi ty of 90~95%and temperature of 20℃-35℃.Using the method of grad ing in advance,the qualified nursery rate of one-year-old seedlings increased fr om 70%to more than 80%.The efficient breeding technology system of C.h ystrix can provide relevant reference for the subsequent production of C.hystrix seedlings.
