1976年我场第一次繁殖水杉苗,母条从外地调入。为了自力更生解决种条问题,我们采用埋棵育苗法繁殖水杉1.1亩,总产苗量32712.9株,亩产29739株,平均苗高54.5厘米。埋棵育苗的好处是:(1) 母株具有根系,成活率极高。据10月8日现场调查,1.1亩水杉全部满苗,没有断条缺苗现象,而在相同条件下,埋条育苗断条现象严重,硬枝扦插苗成活率也只有76.5％。(2) 产苗量高。每亩产苗29739株,为埋条法的1.6倍,为硬枝扦插法的1.8倍。(3) 苗木健壮。平均苗高54.5厘米,为埋条苗的2.8倍,为硬
In 1976, my field first breed metasequoia seedlings, mother from the field transferred. In order to solve the problem of self-reliance, we planted seedlings nursery stock planted with 1.1 acres of Metasequoia, the total output of 32712.9 plants, 29739 mu per mu, the average height of 54.5 cm. The benefits of planting seedlings are: (1) the parent plant has a root system, high survival rate. According to the site survey on October 8, all the seedlings of 1.1 mu of Metasequoia glyptostroboides were lacking in the phenomenon of lack of seedlings. Under the same conditions, the phenomenon of broken seedlings was serious, and the survival rate of hard-cut seedlings was only 76.5%. (2) high yield of seedlings. 29,739 strains of seedlings per mu, 1.6 times for the buried bar, and 1.8 times for the hardwood cuttings. (3) seedlings robust. The average seedling height 54.5 cm, 2.8 times buried barley seedlings, hard
