建立木麻黄无性系种子园,是实现木麻黄良种化的一项重要措施。要建立这样的种子园,必须首先解决木麻黄的嫁接技术问题。今年3月以来,我们和东海岸林场和湖东林场的科研组一起,开展了木麻黄嫁接试验,摸索出“切干皮下枝接法砧木保留旺盛活侧枝”的木麻黄嫁接法。我们用此法嫁接31,700株,成活1,500株,成活率达93%。现将具体做法简介如下: 一、砧木:选择高1-1.5米、基径1-1.5厘米、生长健壮、基部有旺盛的活侧枝的一年生实生苗作砧木。
The establishment of Casuarina clonal seed orchard, is an important measure to achieve good breeding of Casuarina equisetifolia. To establish such a seed orchard, we must first solve the technical problems of the grafting of Casuarina. Since March this year, we and the research group of the East Coast Forest Farm and Hudong Forestry Center together to carry out the Casuarina grafting test to explore the “cut dry subcutaneous grafting rootstock retains exuberant living side branches,” the Casuarina grafting method. We use this method grafted 31,700 strains, 1,500 survived, the survival rate of 93%. Now the specific approach is as follows: First, the rootstocks: choose 1-1.5 meters high, 1-1.5 cm in base diameter, robust growth, the base of live lively branches of annual live seedlings as rootstock.
