长柄石笔木播种育苗试验研究

通过对长柄石笔木的种子采集处理、种子主要参数测定及育苗方法进行试验和对苗木观测调查,初步研究了长柄石笔木的育苗技术、苗期生长规律。结果表明:长柄石笔木大田育苗播种量以150 g/m2为宜,1年生苗高平均可达60 cm,地径平均0.58 cm,根系较发达,可出圃造林;苗高生长高峰在8月至9月上旬,期间应加强水肥管理,促进苗木生长。

Exprimental Study on Sowing and Sexing Raiaing of Tutcheria Greeniae

Seed's collecting,determination of seed's main parameters,technic of seedlingraising and growth observation of Tutcheria greeniae were researched in detail.The growth rules and seedlingraising technic of this specie were also discussed.The result indicated that 150g/m2 were the better quantity for sowing and seedingraising in the field.The average height of one year old seedling of Tutcheria greeniae was 60cm,the average ground diameter was 0.58cm,and the root system was strong,all these characterristics could be better used for afforestation,the growth peak of Tutcheria greeniae was from Aujust to the beginning of September.Water and fertilizer management should be strengthened to promote seeding growth.
