杉木是浙江省和亚热带地区最主要用材树种之一，然而杉木人工林普遍存在林分结构简单、土壤质量退化、系统功能偏低等突出问题，直接影响我省森林总体质量提升和碳汇功能发挥。该成果通过15年的持续攻关，系统开展了以林分结构优化为主的杉木人工林提质增效关键技术的研究与应用工作。创新了杉木人工林密度控制、植被控制和轮伐期控制技术，提出了亚热带杉木用材林优化培育模式；揭示了杉木-微生物互作对林木生长和土壤养分有效性...
马尾松（Pinus massoniana）速生、耐干旱瘠薄、适应性强，是我国南方荒山造林的先锋树种和针叶用材树种，人工林面积仅次于杉木。马尾松也是我国最主要的采脂树种，约70%的松脂来自于马尾松。但目前松材线虫病已成为制约我国马尾松产业发展的主要因子。针对其育种进程缓慢、良种不能满足当前需求、种子园产量低及种苗繁育技术落后等重要问题，中国林科院亚林所林木遗传育种与培育研究团队联合国内多家单位，开展...
针对我国笋用竹栽培中主栽笋用竹种少，出笋迟、笋期长、品质佳的优良笋用竹种不多，资源开发利用不够，高品质竹笋市场供应不足及集约经营竹林竹笋品质劣变等问题，从生物学和生态适应性研究入手，发掘出高节竹、四季竹、黄甜竹和苦竹等4种生态适应性强、出笋迟、产量高、品质佳的优良特色笋用竹种，阐明了其构件强烈的自适应调节规律与资源分配策略，揭示了形态塑性和叶片功能性状的林分密度效应,提出了基于立竹形态可塑性和叶片...
杜仲种植存在的几种常见问题及解决方法（图）
杜仲种植 常见问题 解决方法
2024/4/1
杜仲栽后生长 5～7 年即可采收，每株一年环剥一次，2～3年为一个周期；每次每株一般产干品3～5公斤，10～25年的成龄树产量可达10公斤以上。而种植中因为种植户们存在的几种常见问题，容易造成减产，效益下降。
黄柏的种植技术（图）
黄柏 芸香科 落叶乔木 种植技术
2024/3/22
黄柏（黄菠萝）为芸香科落叶乔木，有清热解毒、泻火燥湿等功能。主治湿热泻痢、黄疸、小便淋沥涩痛、赤白带下、热毒疮疡、湿疹、阴虚、盗汗等症；其木质细腻是建筑和用做家具的上等原料，可以说黄柏是药木两用植物。目前黄柏野生资源严重缺乏，被列为国家一级重点保护植物，人工栽培前景广阔。
