| 摘 要： | 在分析罗田县板栗低产林现状的基础上,总结了5种低产林类型及分类改造试验结果。改造试验结果得出,低产林用良种穗条嫁接换种后,第4~5 a能达到丰产水平,经济效益增加最高;密林疏伐改造将栗林密度控制在30~45株/667 m~2,恢复产量见效快;整形修剪增产明显,能有效调节板栗大小年,实现稳产。生产中低产林因其不同的形成原因,成为多种类型的综合体,需各种改造技术组合使用,达到效益最大化。

Low Production Forest Improvement and Economic Benefit Analysis on Chestnut in Luotian County |
| |
| Abstract: | In this paper low production chestnut forest in Luotian county was divided into 5 types,the improvement tests results showed that:After grafting improved varieties,the forest can reach to high level yield in the 4th to 5th year,which increased the most economic benefit;The density thinning in jungle should be controlled in 30 to 45 plants per 667 m2;pruning can also increase production,and adjust alternate bearing effectively.Every low production forest of chestnut caused of its different forming reason is a complex of several types,and it need the combination of those reconstruction technology to maximizing the benefit. |
