1987年和1992年两次从辽宁建平引种沙棘苗10.8万株,在土壤含盐量高达8.2%的上古林东大荒等地,作为护堤林、农防林栽植。当年成活率75%,由于管理不善,保存率仅为50%。保存下来的沙棘至今高达3m。1990年,从黑水林场调入3万株沙棘苗,在中塘、小王庄、沙井子3个乡镇进行归圃育苗0.5hm~2 ,成活率达90%,年均高生长80cm。1991年和1994年两年栽植片林1.3hm~2,由于加强管护,成活率90%,年高生长量110cm。在中塘镇播种育苗0.3hm~2,播种前进行浸种、催芽处理,平床高垅条播。当苗高25cm时进地定株,出苗率64%,当年生长量98cm。
In 1987 and 1992, two hundred and eighty-eight plants of seabuckthorn seedlings were introduced from Jianping, Liaoning Province. In the Great Eastern Great Eastern Great Forest where the salt content of soil was as high as 8.2%, they were planted as embankment forests and agricultural and forestry prevention forests. The survival rate of 75% that year, due to poor management, preservation rate of only 50%. Seabuckthorn preserved up to now 3m. In 1990, 30,000 sea buckthorn seedlings were transferred from Heishui Forest Farm and nursery nursery 0.5hm ~ 2 in Zhongtang, Xiaowangzhuang and Shajingzi with a survival rate of 90% and an average annual growth of 80cm. In 1991 and 1994, planted forest 1.3hm ~ 2, due to strengthening management and protection, the survival rate of 90%, the annual growth rate of 110cm. Sowing seedlings in Zhongtang town 0.3hm ~ 2, sowing seeds before sowing, germination treatment, flat bed high sowing. When the height of 25cm into the plant, the emergence rate of 64%, then the growth of 98cm.
