文冠果苗期生长规律研究

Study on the Growth Law of Xanthoceras sorbifolia in Seedling Stage

对文冠果1年生苗的生长规律进行了研究。结果表明,文冠果1年生播种苗高生长可分为出苗期、幼苗期、速生期和生长后期4个时期,速生期苗高、地径生长量均达到全年最大,分别占全年总生长量的82.3%和47.3%。

The growth law of 1-year old Xanthoceras sorbifolia seedlings was studied. The results showed that the height growth of 1-year old sown Xanthoceras sorbifolia seedlings could be divided into 4 stages of seedling emergence stage,young seedling stage,rapid growth stage and late growth stage. The growth increments of seedling height and ground diameter in rapid growth stage reached maximum of the whole year,accounting for 82.3% and 47.3% of total growth increment of the whole year resp.
