雪花皮是一个投产快效益高的经济林树种,也是重要的水土保持树种。我们曾以“南方优良固土树种——雪花皮”为题,在《中国水土保持》和《湖南林业科技》上作了报道,随后我国大江南北有关单位和地区,纷纷来信来电或来人要求供应种苗。在当前雪花皮只能分株造林的情况下,为了争取部分解决种苗不足和长途运输中的困难,我们进行了雪花皮扦插育苗试验,情况于下: 扦插时间:1984年3月20~22日,扦插面积为10平方米。圃地原系荒地,砂壤土,粒状结构,肥力较差。 插条来源于本站小流域治理所订购的一年生幼
Snowflake is a quick economic and effective production of economic forest tree species, is also an important soil and water conservation tree species. We have reported on “China’s soil and snow conservation” and “Forestry Science and Technology in Hunan Province” with the title of “Excellent Southern Soil Species - Snowflake Skin”. Afterwards, many units and regions across the country have sent letters or requests for supplies Seedlings. In the current snow can only ramets afforestation circumstances, in order to fight part of the fight to solve the problem of insufficient seedlings and long-distance transport, we conducted a snowflake cuttage nursery trials, the situation in the next: cutting time: March 1984 20 ~ 22 Day, cutting area of 10 square meters. Nursery area of the original wasteland, sandy loam, granular structure, poor fertility. Cuttings from the site of small watershed management ordered one-year-old child
