摘要
红花木莲1年生苗木苗高生长出现2个高峰期,分别在7月中旬和9月下旬;地径也呈现出相同的规律,比苗高迟30~40d,分别在8月下旬和10月下旬;将苗木生长期分为出苗期、幼苗期、速生期、生长后期4个阶段。根据各阶段苗木的生长特点,提出了关键育苗技术措施,以提高苗木的成苗率、质量与产量。
The observation and analysis of Manglietia insignis during the seedling stage showed that 2 peak stages of 1-year-old seedling height growth were the middle of Jul.and last 10-day period of Sep.,directly;the ground diameter growth assumed the same law,those of ground diameter growth,last 10-day period of Aug.and last 10-day period of Oct.directly,were 30~40 days later than those of seedling height growth;the seedling growth stage was divided into the 4 stages of emergence stage,seedling stage,fast-growing stage,and later growth stage.According to the growth characterictics of seedling in different stages,the key seedling raising technical measure was raised to raise the seedling planting percent,quality and yield.
