采用营养袋育苗方法,对老虎刺1年生苗的生长规律及其不同播种期对老虎刺苗木生长的影响进行了初步研究。结果表明:老虎刺1年生播种苗高生长分为出苗期、幼苗期、速生期和生长后期4个阶段,速生期苗高生长量达到全年最大,占全年总生长量的77·5%。1年生苗木的平均高为53·2cm。
Using the method of nursery bag cultivation, the effects of different growth stages on the growth of tiger sprout seedlings were studied. The results showed that the growth of 1 year annual seedling height was divided into 4 stages, ie seedling stage, seedling stage, fast growing stage and late growing stage. The growth of seedling height in fast growing stage reached the maximum throughout the year, accounting for 77.5% of the total annual growth. . The average annual height of one year old seedlings is 53 · 2cm.
