摘要
采取毛竹种子不同方式浸种育苗技术试验。种子选择12年生以上优质母树采种之后其一用50℃温水消毒浸种,其二用1∶1000的多菌灵溶液消毒30min后、再用温水浸种24min,其三用吲哚丁酸500PPM溶液浸种12h即可播种。各试验播种量2kg,播种面积各0.067hm2,用吲哚丁酸500PPM溶液浸种的种子发芽率,比用清水消毒浸种的种子和用多菌灵溶液消毒后温水浸种的种子发芽率分别提高25.40%、16.18%,苗木萌芽出土率也分别提高21.52%、12.94%;苗木生长量苗高分别提高30.77%、17.24%,苗径分别粗24.00%、16.98%,出笋率分别提高55.56%、40.00%,苗竹冠分别增宽大33.85%、19.18%。
This paper conducts the experiment of different seeding techniques of phyllostachyspubescens. After seed selection, the seeds were sterilized and soaked with warm water at 50℃,sterilized with 1:1000 carbazol solution for 30min, and then soaked in warm water for 24min.The seeds were seeded with indolebutyric acid 500PPM solution for 12h.The germination rate of seeds soaked with 500PPM indolebutyric acid solution was 25.40% higher than that of seeds soaked with water and 16.18% higher than that of seeds soaked with warm water after disinfection with polyfungicide solution. The germination rate of seedlings also increased by 21.52% and 12.94%, respectively. The seedling growth rate increased by 30.77% and 17.24% respectively;the seedling diameter increased by 24.00% and 16.98% respectively;the emergence rate increased by 55.56% and 40.00% respectively and the seedling crown widened by 33.85% and 19.18% respectively.
