In this paper, the drag effects of the precipitation particles on the air current in convective cloud are investigated, by applying the theory of motion of sand particles. It is found that: 1) the downward velocity of air thus produced is reasonable; 2) the precipitation has the character of a shower.

本文进一步研究了对流云中,降水貭点对气流的拖带作用。把降水貭点和空气作为混合介貭看待,根据泥砂輸运理論,重新推导了問題的基本方程組.在这一基础上,分析了問題的常定和非常定解。得到两点主要的結果:1)按云中实际可能出現的含水量数量,通过拖带作用后,可以产生与观測結果同量級的下沉气流强度;2)云中降水泡(降水集中区),在降落过程中,水量将向泡的前沿区集中,由于水量的这种聚集,降水到达地面时有可能出現陣性,即降水强度一开始就很大。

The following conclusions can be drawn from the present analysis:(1)It is practical to think that the migration of the moths can be solved into 3 succes-sive components,namely,the“ascending movement”,the“transmigration”and the“descend-ing movement”.The analysis of the last one and its association with certain meteoro-physicalconditions helps us to find out the intrinsic and extrinsic causes affecting such movement aswell as to appreciate their relative values.(2)Through an actual analysis of 163 cases of“sudden...

The following conclusions can be drawn from the present analysis:(1)It is practical to think that the migration of the moths can be solved into 3 succes-sive components,namely,the“ascending movement”,the“transmigration”and the“descend-ing movement”.The analysis of the last one and its association with certain meteoro-physicalconditions helps us to find out the intrinsic and extrinsic causes affecting such movement aswell as to appreciate their relative values.(2)Through an actual analysis of 163 cases of“sudden high catch”that happened inthe 985“favorable air current for moth-carrying”conditions,it is realized that in theprocess of decending movement the intrinsic habitual response should not be neglected.It isquite possible that such movement is the“kinetic reaction”under certain external environmentalconditions.The most important factors that determine whether moths would decend in a certaindistrict or not,might be the“circadian rhythm”and the meteoro-physical conditions.(3)It is found that the association of“sudden high catch”and certain weather condi-tions is close and significant.Moreover,under different weather conditions,the conditionalprobabilities are all different.(4)Among the weather conditions,“cyclonic center”,“cold front area”and“thunder-storm”are all favorable for the decending movement of migrating moths.Raining weatherranks next to the above mentioned ones;while under the so-called“general weather conditions”,the frequency of occurrence of“sudden high catch”is relatively low(see Table 4).(5)A possible mechanism of the decending behavior has been discussed.It is pointed outthat“cyclonic pocket”,“air disturbance”and“decending air movement”may constitue thephysical causes of such reaction.Rainfall in a certain degree may also favor the descent ofmoths,while the ascending air movement may be unfavorable for such movement.

本文对气流场与粘虫迁飞关系作了分析,表明在900—950mb 层(即400—900米高度)气流场中有适于携虫的气流存在。在各类气象条件下,粘虫蛾发生突增的条件概率,其结果(在气流有利于携虫的前提下):无条件概率值为0.1665;各条件概率值分别为:在雷暴状况下发生突增的条件概率为 0.4000;在降雨状况下发生突增的条件概率为 0.2812;在冷锋区发生突增的条件概率为 0.3720;在暖锋区发生突增的条件概率为 0.2222;在气旋中心区发生突增的条件概率为 0.4000;在“一般性天气”发生突增的条件概率为 0.1166;因此,初步结论是:气旋中心区、冷锋区、与雷暴均显著地有利于扩迁粘虫蛾的降落,而降雨、暖锋区、虽然也有或多或少的有利倾向,但是不够显著。由于在“一般性天气”条件下亦有相对多的蛾量突增的现象发生,这表明很可能降落过程与运转过程不同,在一定程度上与粘虫本身的自主性降落有关。估计这很可能与粘虫蛾的“生物钟”反应有所联系。在本文中亦对各种气象物理事件对于扩迁粘虫蛾降落过程的可能作用机制作了讨论。

Black spot of cotton seedlings caused by Alternaria tenuis Nees.Formerly designated as“zenate leaf spot”is differentiated from the true zonate leaf spot of cotton caused by A.macrospora Zimm.The former appears on the cotyledons and the young true leaves asirregular brownish-black spots which then covered with olivaceous sporulations with a fewinconspicuous zonations,while the later occurs most prevalent in the late autumn as circularbrown spot with several zonations.Owing to the fact that spores of this pathogen was disseminated by air current,the seedtreatment or crop rotation alone,was not sufficient to attain satisfactory control.The disease development was closely correlated with chilling and wind injuries of theseedlings and also with growth-stage of the plant.The date of disease incidence varied withyears and was apparently influenced by the climatic factors.This correlation suggested thepossibity for prognosis.It was suggested that for avoiding the chilling and wind injuries in the seedling stage,anadequate early thining was to be scheduled.The varietal difference in resistance to this diseasewas not significant.However it was demonstrated that,the application of a mixture ofBordeaux mixture and E1059 before the temperature lowering,yielded a fair result.

棉苗黑斑病的致病菌在关中棉区初步认为是 Alternaria tenuis Nees 与棉成株期叶片上的致病菌不同。病菌孢子借气流传布。种子带菌率虽然很高,但诱发苗病率却很低,因此,种子消毒或采用轮栽来控制这个病害,是不能达到预期效果的。病害发生与棉苗受冻、强风对棉苗的伤害以及棉苗阶段发育有密切的关系。各年发病期有早有晚,但以真叶出现时为易感阶段。本文阐述了棉苗生育阶段、气候条件与发病的关系,为预测病害发生的物候与气象参考条件提供了资料。棉株伤害与发病有关系,建议在生产上适当降低播种量,提高播种质量,适期早疏苗、早间苗;以减轻由于伤损而导致病害侵染。品种与病害发生的关系不显著。试验证明,使用波尔多液加1059于降温前喷射效果较好。
