联邦德国正在风倒木林地上进行大规模的森林更新。多年实践表明,用纸浆板、苯乙烯海绵塑料及塑料制成的各种各样植苗钵对造林苗木不太适用。 在赫斯坦那(施瓦布斯克尤拉)一个森林苗圃制造了一种新型带软边的植苗钵。植苗钵容量达3升,是由纤维素、纺织纤维和浸染药物制成。当植苗钵同土壤和腐殖质接触时,苗木的根就无阻碍地穿过软边长出来。在植苗钵互相接触时亦出现这样情况。
The Federal Republic of Germany is sweeping down the woodland for large-scale forest renewal. Years of practice have shown that a wide range of seedlings made from pulp boards, styrofoam plastics and plastics are not suitable for reforestation seedlings. A new soft-edged seedling pot was made in a forest nursery in Herstanna (Schwabiskeula). Seedling pot capacity up to 3 liters, is made of cellulose, textile fibers and impregnated drugs. When seedling seedlings are brought into contact with soil and humus, the roots of seedlings grow unimpeded through the soft edges. This happens when the seedlings are in contact with each other.
