本文通过对不同储藏条件下的白被野桐种子进行播种育苗,定期观察记录种子出苗率、苗高和地茎,研究白被野桐1年生幼苗苗高和地茎的生长规律。结果表明,沙藏白被野桐种子发芽率最高,为29.70%;苗高和地茎增长都呈“S”型增长模式,苗木增长出现缓慢期、速生期和停滞期3个时期;苗高速生期起点为7月上旬,持续至9月中旬,在8月中旬出现苗高速生点。地径速生期起点为8月上旬,持续至9月下旬,在8月中旬出现地径速生点。

In this paper seedling-raising experiments with Mallotus apelta seeds in different storage conditions were carried out and the seed germination rates,seedling heights and basal diameters were observed and recorded at regular intervals to study the height and basal diameter growth rhythms of the 1-year-old Mallotus apelta seedlings. The results showed that the sand-storage seeds had the highest germination rate of 29.70%. The seedling height and basal diameter increments followed an“S”pattern with the slow,fast and stagnant growth periods. The seedling height fast growth period started in early July and lasted until mid-September with the appearance of the fastest height growth point in mid-August. The basal diameter fast growth period started in early August and lasted until late September with the appearance of the fastest basal diameter growth point in mid-August.
