Root systems and above ground biomasses of 33 Chinese fir sample trees were studied. Results showed that the distribution of Chinese fir roots depend on soil bulk density and system of cultivation. The root of Chinese fir is aerobic and intolerent to waterlogging. It prefers fertile soil but is weak in competition with other plants.

本文记述了在杉木根系研究中采用的方法——重量法。按照这一方法于1973—1979年间在苏南丘陵区调查了33株2—20年生杉木的根系及地上部分生物产量。研究结果表明: 一、丘陵区杉木根系分布的特点具有明显的浅根性,根系主要集中分布于0—20厘米的土层内(占根量的80%);根系分布因土壤容积重和营林措施的不同表现出一定程度的可塑性,即土壤容积重愈大,根系愈集中土壤表面,地上部分生长愈差,深翻能减轻土壤容积重,促进杉木根系分布位置有一定程度的下移。 二、杉木根系具有明显的趋肥性、好气性、怕水渍和与杂草竞争能力弱等生态特性。 三、杉木根量(ω)的大小与树高(H)之间呈幂函数关系:(ω=3.430H~(1.3686) 四、杉木地下与地上部分生物量之间的比例关系(地下:地上=1:y),随树高(H)而变,呈对数曲线关系:y=0.3067+3.5321lgH。 掌握了杉木树高与根量,树高与地下和地上部分的比例关系后,只要测出林分平均高就能粗略地计算出林分的生物产量。

The introduction of olives into various regions of Jiangsu Province has proved successful. Based on the research work made in the past twenty years, causes and significance of the success are here discussed, districts suitable for olive cultivation suggested and proposals for their further development raised.

本文通过对江苏省油橄榄引种二十年的总结,从生态学的观点讨论了引种成功的原因和意义,并在此基础上提出了适栽区划和进一步发展的意见。 1.江苏省植物研究所从1959年开始进行油榄榄的引种驯化研究,至今共收集保存了92个品种。全省定植约5万余株,分布在32个县(市)。其中以太湖地区的吴县和无锡两地生长发育最为良好,幼树结果早,而且几乎所有品种都能适应当地的生境。南京和墟沟两地的油榄榄在正常年份较丰产,1979年分别获得折合亩产300—400公斤和638.8公斤的小面积高产记录,接近和超过了地中海地区的高产水平。 2.通过与原产地生境因子的比较,认为江苏与国内其他引种地区相比,降水量较少,日照较多,在自然条件方面具有较大的优越性,但是,冬季低温是这一地区的限制因子。 3.提出以一月份平均温度、地形、土壤等自然条件为区划的主要依据,将一月份平均温度>2.5℃的地区划为适宜栽培区,1.5—2.5℃等温线内的西部丘陵及云台山东部为次适宜栽培区,其他地区为引种试栽区和不适宜区。 4.提出了江苏省油榄榄发展必须采取小面积栽培方式,走集约化道路。

Ginger(Zingiber officinale Rose.)is one of the major tuber crops in China,and it is of great importauce bearing on the daily life of people.In practices the cultivation of ginger according to it’s growth and development is a outstanding experience of our ginger growers. The aim of this experiment is to investigate systematically the re- gularity of growth and development of ginger on the basis of the experience of ginger growers,so that to find out the theoretical ba- ses for improving its cultural practices,thus to raise its yields and qualities still further. In this experiment,we selected“Lai-wu”ginger as studying mate- rial.The morphological characters,increment and growing trends of organs were observed measured. Based upon the experience of ginger growers and the results of our experiment,it was Shown the entire process of growth and develop- ment of ginger from planting to harvesting may be divided into four stages. 1.The sprouting stage—from emergence of the buds to the first leaf spread.The growth of the buds depends mainly on the nutrition of the seed piece,since there is no dormancy in ginger,during this stage,it is only necessary to furnish favourable conditions mainly the higher temperature for sprouting. 2.The seedling stage—from the first leaf spread to the plant with two or three branch stems.At the beginning of this stage,the pho- tosynthesis starts on and the seedling begin to make it’s independent living.But the increment of dry matter of the seedling is less. During this stage,it is necessary to step up the development of the root system of ginger and to strengthen the seedling with intensive c- ultivation. 3.The thriving growth stage—from the plant with two or three br- anch stems to the harvest of new tubers.The branch stem,leaf and the tuber all grow with great speed.The increment of dry matter of the plant is highest.During this stage,it is necessary to give some su- itable conditions for the expanding of the tubers. 4.The dormancy stage.After hervest,the tubers are stored and go into rest.During this stage,in order to protect the tubers of ginger from the cold and dry up,we must furnish suitable temperature and moisture.

本试验是在调查总结农民经验的基础上,系统地研究生姜各个不同生长时期植株各器官的发生、建成和生长动态。试验结果看出:生姜的生长过程有明显的阶段性,可以顺序地分为发芽、幼苗,旺盛生长和休眠四个时期,并根据生姜各个生长时期的生育特点,提出了相应的栽培管理的基本原则。
