泡桐生长快,材质好,用途广。经济价值高,但目前苗木供不应求,影响发展。为解决桐苗暂时不足的困难,我们试用桐根造林,收到了良好的效果。现将其方法介绍如下: 1.选根:以选粗0.9—1.0厘米一年生无病害的桐根为好。过细,生长势差,过粗成苗率低。剪成的根段长10—15厘米。为防止种根水份过多,腐烂,可晒1—2个太阳,使根皮略起皱状为度。 2.开塘:直接用桐根埋根造林,株行距和其它树种造林一样,一般3米左右。开塘深宽各50—60厘米。塘底,每塘施猪脚灰或人粪尿15斤左右,而后填满熟土。
Paulownia grow fast, good material, wide use. High economic value, but the current shortage of seedlings, affecting the development. To solve the temporary shortage of Tong Miao, we try Tong root reforestation and received good results. The method is now introduced as follows: 1. Election: to choose the crude 0.9-1.0 centimeters disease-free Tong root as well. Too thin, poor growth potential, too coarse seedlings rate is low. Root segments cut into 10-15 cm long. In order to prevent the root of water too much, decay, can sun 1-2 sun, make the root leather slightly wrinkled degree. 2. Kai Tong: Direct rooting with Tong root afforestation, plant spacing and other tree afforestation, generally about 3 meters. Kai Tong deep width of 50-60 cm. At the end of the pond, pigs pigs feet per pond or human waste urine about 15 pounds, and then filled with cooked soil.
