1990~1994年,在福建平潭、长乐、莆田等地采用福建省林科所和华东农业大学的科技成果,开展了速生、抗病木麻黄良种无性系育苗、造林技术推广工作。5年共培育水培苗99.875万株,造林399.2hm2,成活率在90%以上。树高年平均生长量可达2m,比常规实生苗的高生长量提高2倍。造林一年后,幼林保存率比当地实生苗高34.5%,幼树高生长比当地实生苗高0.71m,地径增粗0.72cm。5年的试验推广,取得了明显的经济效益、社会效益与生态效益,解决了沿海防护林体系工程建设中存在的木麻黄青枯病危害严重,造林成活低等问题,探讨出二代更新的有效途径。
From 1990 to 1994, the achievements of science and technology of Fujian Forestry Bureau and East China Agricultural University were used in Pingtan, Changle and Putian of Fujian Province to carry out popularization and afforestation technology popularization of fast-growing and disease-resistant Casuarina equisetifolia. In five years, a total of 998.55 hydroponics plants were cultivated, afforestation 399.2hm2, the survival rate of more than 90%. The average annual growth of trees up to 2m, higher than the conventional growth of seedlings increased by 2 times. One year after afforestation, the preservation rate of young forest was 34.5% higher than that of local seedlings. The height growth of young trees was 0.71m higher than that of local seedlings, and the diameter of soil was increased by 0.72cm. Five years of experiment and popularization has yielded obvious economic, social and ecological benefits, solved the problems of the serious damage of Casuarina bacterial wilt and the low afforestation survival rate in the construction of coastal shelter forest project, and explored the effective second generation renewal way.
