天然茶秆竹不同垦复措施的效果研究

对天然茶秆竹采取不同垦复措施后的出笋数、成竹数、成竹率进行统计分析,结果表明:(1)不同年度的天然茶秆竹采取相同的垦复措施,垦复效果一年比一年好;(2)茶秆竹林采取不同的垦复措施效果不同:采取劈山+全锄+施肥处理,2a出笋数10995株·hm-2,比其它2种措施提高15 5%～16 0%。成竹数7455株·hm-2,提高20 5%～23 3%;成竹率67 8%,提高4%～5 9%,明显高于其它2种措施;(3)经过劈山+全锄处理的茶秆竹发笋个数和新竹株数与劈山处理的差异不明显。

Study on the Effects of Different Reclamation Measures of Natural Pseudosasa amabilis

The results showed that:(1)the same reclamation measure was adopted to the natural Pseudosasa amabilis in different years,and the reclamation effect of every year was better than that of last year;(2)different reclamation measures were adopted to the P.amabilis forest,and the effects with the measures were different,the shooting number was 10 995 trees/hm2 with the treatment of chopping hills+wholly hoeing+fertilization in 2 years,which increased by 155%～160% as compared with the numbers with other 2 methods.The adult bamboo number was 7 455 trees/hm2,which increased by 205%～233%;the adult bamboo rate was 678%,which increased by 4%～59%,and was higher than the rates with other 2 methods;and (3) the differences between P.amabilis shooting number and new bamboo number with the treatment of chopping hills+holly hoeing,and those with the treatment of chopping hills weren't evident.
