泡桐育苗多用埋根法(一般3月埋根,4月开始出苗,5月末达全苗),它年高生长期短,当年达不到高于壮苗要求。为提高苗木的产量和质量及当年出圃造林的目的,1978年进行了营养钵育苗,结果5米高苗的出圃率达81.6%(附照片)。 Paulownia nursery multi-purpose buried root method (usually buried in March, April began to emerge, the end of May reached the whole seedlings), its high growth period is short, then not higher than the strong seedlings requirements. In order to improve the yield and quality of nursery stock and the goal of afforestation in that year, nutrition seedlings were raised in 1978, resulting in a yield of 81.6% (with photos) of 5-meter seedlings.
