摘要
目的建立黄连种子湿沙棚贮、精细育苗技术,提高黄连种子育苗率。方法以老式撒茅林育苗技术为对照,筛选出新的种子贮藏和育苗方法。结果5月采收种子用湿沙棚贮到11月,采用精细育苗方法播种,发芽率达98%,每千克种子可育苗14万株。结论精细育苗技术比原撒茅林育苗方法黄连种子育苗率提高8倍,并已在大面积生产中推广应用。
Objective To develop technique of storing Coptis chinensis seeds in damp sand under shed and fine cultivation of seedling and to enhance the cultivation seedling rate from seeds of Coptis chinensis. Methods With the old technique of seedling in woods as control we screened the new method forstoring seeds and cultivating seedlings. Results Seeds were picked up at May and stored in damp sand under shed until November and then planted with technique of fine cultivation of seedling. The germi-nation rate of seeds was up to 98%. One hundred and forty thousands seedlings could be getting from per kilogram seeds. Conclusion Compared to the old method of cultivating seedling in woods the te-chnique of fine cultivation of seedling significantly increased the rate of cultivation seedlings by 8 times. This technique has been widely applied.
