在白菜光合作用的试验中发现白菜的光合强度水平不高。各种白菜及其品种的光合强度与叶绿素含量有显著的正相关。白菜在生长过程中各个时期的光合强度不同:幼苗期最低,莲座期增高,结球期最高。温度对光合作用有显著的影响。植株中下层叶片对较弱的光照强.度有适应力。一日间的光合强度依温度和光照强度而变迁,在水分充足的情况下,蒸腾强度对光合强度无显著的影响,但叶子萎蔫使光合强度显著降低。用含氮肥料的溶液进行根外追肥能显著地提高光合强度。

The tobacco leaf miner (i.e. potato tuber moth, Gnorimoschema operculella (Zeller)) is widely distributed in the tobacco growing districts of Yunnan Province and is one of the worst pests of the tobacco plant. In Southern Yunnan where the temperature is comparatively higher, there is another serious pest of tobacco, the tobacco stem borer (Gnorimoschema heliopa (Lower)). At seedling stage, the affected young stems are stimulated to produce galls or develop into abnormal growth. Finally, the affected seedlings wilt and die off. Not only in the seed bed, but also in the field, tobacco stem borers attack the lateral buds or pith of the tobacco plant. In Kunming, the tobacco leaf miner has four or five overlapping generations. Winter is passed as pupa in the laboratory, but feeding and breeding may be continuous in the exposed warmer place. In Southern Yunnan such as Yangjiaba, Jianshui, the tobacco stem borer has more than four generations a year. The tobacco leaf miner is adopted to warm and arid climate. The occurrence of the tobacco stem borer is closely related with the field management and the environmental conditions. Investigations in the past years have shown that the pest is most serious in the hillside tobacco plots where the soil is very arid, but scarcely occurs when the seedling bed is supplied with sufficient water and the soil is kept humid. Infestations may be prevented by destroying all the tobacco stubbles during winter. To gather and burn up the leaves of the under part of the tobacco plant is an effective control measure against the tobacco leaf miner. Strict quarantine measures against the potato tuber moth should be maintained to prevent its spread.

菸潛叶蛾 (卽馬鈴薯块茎蛾) 在云南普遍为害烟草。在云南南部温度較高地区,还有一种菸草瘿蛾严重为害,菸草幼茎受害后形成虫瘿或成畸形;受害烟苗往往死去。菸草瘿蛾在大田为害侧芽及菸株髓部。本文記述了这两种菸草害虫的为害性及习性。菸潛叶蛾在昆明一年发生4—5代,世代重叠;在室外温暖向阳处可終年活动,在室內飼养則以蛹过冬。菸草瘿蛾在南部建水县羊街埧,一年至少发生4代。菸潛叶蛾喜温暖干燥的气候,栽培管理与环境条件对菸草瘿蛾发生有密切关系。历年調查,在半山坡烟田,土壤干燥处, 虫害严重;苗床水分充足,土壤經常保持湿潤,則很少发生。此外,与土壤、前作都有关系。彻底处理菸草残株,消灭其越冬場所是減少或消灭这两种害虫的主要措施。菸潛叶蛾一般为害脚叶,在大田生长期打脚叶是有效措施。貫彻馬鈴薯的检疫和防治措施,也关系到菸草上为害的輕重。疫区調运种薯,特别是調至菸草种植地区,必須严格检疫。

In damp tropical districts, there is plenty of light, heat and water, so the conversion of matter is extraordinarily rapid, the kinds of organisms extremely multifarious, and the energy exchange between organisms and matter in the environment very frequent. Changes in space distribution and time are apparent, and so organisms have acquired very sensitive reaction. When organic communities change, there follows the rapid variation in environmental conditions. Therefore, the unified, organic integrity of organisms and environment must be studied as a system, and especially as a dynamic system.Thus the theories and methods of systematics can be introduced into biogeography and the biogeoraphical process can be reproduced by means of analogue. of course, this process is very complicated and difficult to analogize. Nevertheless, the chief processes, especially the decisive processes, can be analogized and some biogeographical models can be set up. By means of a computer, we can make quantitative analysis of the biogrographical processes and foretell the tendencies in the changes of these biogeographical processes. This way, we can reduce blindness in the exploitation, application and reformation of natural resources. We won't fell down large areas of forest to get timber, or destroy pastures to enlarge agrarian land, thus to avoid causing serious soil erosion or ecological maladjustment. We can exploit and safeguard the natural environment and natural resources in a rational way, build up an optimal artificial ecosystem and put the conversion of matter in nature in a sound cycle.

在热带湿润地区,光热丰富,水分充足,物质转化异常迅速,生物种类繁多,生物和环境间物质和能量交换频繁。空间分布和时间变化明显。环境条件变化,生物反映异常敏感;生物群体发生变化,环境条件也会随之发生变异。因此,须把生物和环境的统一有机整体当作系统来研究,尤须把它当作动态系统来研究。这样可以把系统论的理论和方法引入生物地理学中,对生物地理过程进行模拟。当然,生物地理过程十分复杂,进行模拟有较大难度。至少对其中主要过程,有决定性过程,模拟是可能的。建立起生物地理模式,利用计算机运算,对生物地理过程作定量分析,对生物地理过程的变化趋势可进行预测。这样,对自然资源的开发,对自然环境的利用和改造,可减少盲目性。不致于为了木材,大量砍伐森林;扩大耕地面,毁坏草场,引起严重水土流失,生态失调,出现严重后果。根据生物地理过程发展和变化的规律,可以合理利用和保护自然环境和自然资源,建立最佳人工生态系统,使自然界物质转化形成良性循环。
