摘要
对遂昌县牛头山林场马头山林区以壳斗科树种为主的天然次生林进行改造,对母树林营建技术进行研究。采取了间伐、杂灌清理、垦复、施肥等技术措施,使种子产量显著提高。研究结果表明,以林分郁闭度控制在0.7左右,每年施复合肥2次,每次施用量为0.5 kg/株,可提高种子产量15%以上。
The natural secondary forest dominated by Fagaceae Species at Matoushan forestry district of Niutoushan Forest Farm of Suichang County was transformed into the seed trees ,and the seed tree construction technology was studied. Technology measures such as thinning ,recultivation , fertilization were carried out ,and the seed yield increased significantly. Results showed that canopy density control in about 0.7 ,annual fertilization with 2 times,and each time applying 0.5 kg each plant,could improve the seed yield of more than 15%.
