杉木种子园不同坡向林下套种红豆杉生长情况分析

Analysis on the Growth of Taxus Chinensis Interplanting under Different Slopes in Cunninghamia lanceolata Seed Orchard

研究不同坡向对杉木种子园林下套种的3年生红豆杉树高、冠幅和地径这3个性状的影响,结果表明:坡向对红豆杉这3个生长性状存在真实影响,对树高性状影响最大,对冠幅性状影响次之,对地径性状影响最小;阴坡比阳坡的生长要好,保存率也较高。

The effects of different slope directions on the height,crown width and ground diameter of three-year-old Taxus chinensis interplanting under Cunninghamia Lanceolata Seed Orchard were studied.The results showed that:the slope direction had a real impact on the three growth characters of Taxus chinensis;the slope direction had the greatest impact on the height character,the second impact on the crown width character,and the least impact on the ground diameter character;the growth of the shade slope was better than that of the sun slope,and the preservation rate was also higher.
