The objective is to find the regularity of hereditary variations in Cunninghamia lanceolata seed orchard and improve the stock breeding efficiency.
为进一步了解杉木Cunninghamia lanceolata种子园子代遗传变异规律，提高杉木群体良种选育效率，以浙江省17个杉木种子园子代为研究材料，于1998-1999年，在临安市横畈林场采用10区组、3~4株小区的完全随机区组设计，营建2片子代试验林。

By the changing tendency of N, P, K, we coudle see N, P decreased significantly, especially P, the concentration of which was deficient for Chinese Fir nomal growing, but K nutrients were unnoted. So we suggestted increasing N, P fertilizer for Chinese Fir normal growing and might rise its yield.
由N、P、K的变化趋势可以看出，在杉木生长的整个周期，N、P含量降低明显，特别是P，其含量远低于杉木生长所需要的P含量的临界值，处于严重缺乏状态，K含量变化不明显，因此，建议在生产中增施N、P肥，以保证杉木正常生长，提高产量。

In this thesis, research on alleviation of autotoxicity by planting mixture of Chinese fir and Broadleaf trees and developing undergrowth vegetation were also done. The results showed that Michelia macclurei and Cinnamomum camphora had positive allelopathic effect on the growth of Chinese fir saplings and developing undergrowth vegetation improved soil decline of Chinese fir plantation.
另外，论文还从植物化感作用的角度，对克服杉木人工林连栽障碍的其它生产措施，如营造混交林及人促林下植被的发育生长，进行了研究：提出了与杉木化学生态关系良好的两种伴生树种，并从化感作用角度证明人促林下植被发育有利于克服杉木人工林的连栽障碍。
-
Forestry management methods on alleviation of autotoxicity in Chinese fir plantation were also studied. Root-stumps from last Chinese fir pure plantation have a negative effect on the replanted Chinese fir saplings because of phenolics from decomposing root-stumps.
本文还针对减轻杉木人工林化感自毒作用的林业经营措施进行了研究，发现杉木人工纯林中的采伐剩余物根桩对下茬杉木幼树的更新有不利的影响，这种不利的影响来自于根桩分解过程中释放的酚类化感物质。

If time that 95% of dry matter is decomposed expresses turnoverperiod of litterfall decomposition,the turnover periods of Chinese fir,Castanopsis fissa,Schimasuperba,Castanopsis fargesii,ficus simplicissima,Maesa japonica,Boehmeria nivea,Woodwardiajaponica,Angiopteris fokiensis and Dicranopteris dicotoma put in 20-year-old Chinese firplantation are 2.7,2.1,3.0,2.2,0.5,1.9,0.3,1.5,0.9 and 3.9 years,respectively;they are 2.2,1.6,2.0,1.6,0.3,1.7,0.4,1.3,0.7 and 2.8 years put in 25-year-old Chinese fir plantation,respectively.
若以95%的干物质被分解后所需的时间表示凋落物的周转期，在20年生杉木林内，杉木、闽粤栲、木荷、丝栗栲、三龙爪、杜茎山、苎麻、狗脊、观音座莲和芒萁的凋落物周转期分别为2.7、2.1、3.0、2.2、0.5、1.9、0.3、1.5、0.9和3.9年；在25年杉木林内，它们分别为2.2、1.6、2.0、1.6、0.3、1.7、0.4、1.3、0.7和2.8年。

Cunninghamia Lanceolata showed that,after Cunninghamia Lanceolata sprout forest had been changed into Schima superba and Cunninghamia Lanceolata mixing forest,tree growth had largely been increased,and the water holding and conserving ability had been upgrated,as well as,the microclimate within forest had been improved,the forest land productivity had been protected.
木荷与杉木萌芽林混交试验，结果表明：杉木萌芽林改造为木荷杉木混交林后，林木生长量大幅度提高，林木和林地持水、保水能力增强，林内小气候得到改善，林分水源涵养能力进一步提高，林地生产力得到维护，为今后杉木多代萌芽林和杉木低产林改造提供科学依据。

The major factors which hinder the sustainable management of Chinese fir plantation include not only the vulnerable subtropical red soil ecosystem which Chinese fir grow in, but also the unitary community structure and the biological characteristic of this artificial forest community. Additionally, the traditional culture system of Chinese fir including controlled burning lead to the degradation of soil ferti-lity.
影响杉木人工林可持续经营的因素是多方面的，主要和杉木人工林所处亚热带红壤区生态系统的脆弱性和杉木人工林群落的单一性及杉木生物学特性等有关，而传统杉木林培育过程中采取一系列传统的营林措施则加剧了林地地力衰退。
