花櫚木林下造林效果的初步研究

摘要：為了解花櫚木林冠下造林效果，以1年生花櫚木實(shí)生苗在不同坡向、坡位的杉木林下進(jìn)行造林，調(diào)查了花櫚木生長量，結(jié)果表明，1年生花櫚木苗木成活率高，生長良好，不同坡向、坡位的林分環(huán)境因子存在差異，但在1個(gè)生長季節(jié)內(nèi)對(duì)花櫚木苗木成活和生長的影響沒有規(guī)律性，需要進(jìn)行長期觀測與研究。

Abstract： One-year old Ormosia henryi Prain seedlings were planted under Cunninghamia laceolata plantations at different slope direction and slope position to understand the afforestation effect according to growth indicators. The results showed that the seedlings had a high survival rate and good growth， and the stand environmental factors were different in different slope direction and slope position. However， the effects on the survival and growth of seedlings during a production season are irregular， this means that a long-term observation and research are needed.

花櫚木主要分布在我國長江以南的安徽、浙江、貴州、江西、湖北等地區(qū)，是我國二級(jí)保護(hù)植物[1]，野生資源少，且分布零散。（剩余3703字）
