日本为甜菜育秧而发展起来的纸钵系统,已被芬兰林学家用于培育树苗生产。1974年在瑞典和芬兰用这种纸钵培育的苗木就占28%(17,500万株)。该纸钵系开口的,截面呈六角形,并以溶于水的胶粘剂粘合。各个纸钵再用水溶胶彼此相连,呈蜂窝状排列(见图)。种植时灌水使胶溶解,于是彼此粘在一起的纸钵也即分开。纸可分三等,其破损率因土壤条件而异。纸钵规格:直径2—10厘米,深3—13厘米。林用纸钵最常见的规格:直径约4厘
The system of paper mortar developed in Japan for sugar beet seedling has been used by Finnish forest scientists to cultivate saplings. In 1974, 28% (175 million) of nursery stock were raised in Sweden and Finland in this mortar. The paper bowl is open, hexagonal in cross-section and bonded with a water-soluble adhesive. The various pots are then connected to each other with a hydrosol, honeycomb arrangement (see photo). When planting, water is added to dissolve the glue, so the pots that stick together are separated. Paper can be divided into three, the damage rate varies with soil conditions. Pot specifications: 2-10 cm in diameter, 3-13 cm deep. The most common specifications of forest pot: about 4% in diameter
