The twenty eight materials were used in this study, Among them, there are N. C2326 coker's258 KY56 and so on. To make permanent sections for microscpic examination, the leavs of tobacco were dealt with by paraffin method, Basing on evident anatomica characters of the leaf blade of the tobacco, the paper puts forward"Tissue ratio"of the tobacco as a result of the study.namely: Tissue ratio=Thickness of palisade tissue/Thickness of spongy tissue The more large tissue ratio was,the better was quality,on the contrary, the quality falls off. At the same time, the tissue ratio have made it possible to evaluate the quality of different varieties of the tobacco at their techincal maturity in the fields instead of having to wait until after harvest. So, the tissue ratio may be applicated as a new method to appraise the quality leaf blade of tobacco

本文应用了28个材料的烟叶,其中有乔庄黑苗、红花大金元、ky56、Cokers258、N、C2326等等。烟叶用石蜡切片法制成永久切片,在显微镜下用目测微尺度量。根据烟叶显著的解剖学特征,提出了烟叶组织比值作为研究结果,即组织比值=栅栏组织厚度/海绵组织厚度,试图用它作为衡量烟草品质之一。试验结果表明:烟叶组织比值越大,品质越佳;反之,品质下降。同时,利用组织比值可以在大田工艺成熟期对任何类型的烟叶品质作出准确的判断,所以,利用组织比值可作为检查烟叶品质的一种新方法。

A pot experiment was carried out with tobacco (N.tobacum) grown on Nanxiong Purplish soils and Laterjtic red soil as a contrast in 1984. The changes of soil K and absorption of K by the plant during the course of tobacco growth were determined, and the yield and quality of tobacco were measured. Complementary field investigations were also conducted. Experimental results indicated:The contents of various forms of K in Nanxiong Purplish soils were medium to high.

A pot experiment was carried out with tobacco (N.tobacum) grown on Nanxiong Purplish soils and Laterjtic red soil as a contrast in 1984. The changes of soil K and absorption of K by the plant during the course of tobacco growth were determined, and the yield and quality of tobacco were measured. Complementary field investigations were also conducted. Experimental results indicated:The contents of various forms of K in Nanxiong Purplish soils were medium to high. The release of K by weathering of minerals was relatively quick, and the capabilities of K Supply and preservation in the soils were comparatively strong. Non-exchangeable K was an important sourse of the K nutrition of tobacco, therefore it should be taken as an important index for evaluating the roils in tobacco-plentirg district. The percentage of K contained in tobacco plant was the highest in the period of rapid growth, and the amounts of K absorbed by the plant in various periods were in decreasing order, harvest period, rapid growth period and early growth period. Both were enhanced by the rsjse of the level of K fertilization. For the Purplish soils high jn K,K fertilizing had no significant influence on tobacco yield, but benefied the improvement of tobacco quality; for the one medium in K, it had beneficial influences on tobacco yield and quality. The effect of low level of K fertilization was a bit better. K fertilizing to Lateritic red soil could improve tobacco yield and quality significantly and made the symptoms of K deficiency disappear, and the effect of higher level of K fertilization was more significant. The proper time for K fertilizing was the early part of rapid growth period.

本文研究广东省南雄紫色土含钾量、钾素供应和烟草吸钾的特性及其对烟草的产量和品质的影响,并以花岗岩形成的赤红壤作比较。于1984年进行盆栽试验,且辅以化学分析和适当的田间调查。试验结果表明:南雄紫色土含钾量属中等至丰富水平,矿物风化释钾较迅速。供钾和保钾能力较强。烟草吸收缓效钾量约占其吸钾量的1/3至1/2,缓效钾是烟草钾素营养的重要给源,应作为烟区土壤评价的一个重要指标。烟草植株含钾率在旺长期最高,而吸钾量则是成熟期>旺长期>伸根期,两者均随着施钾水平提高而增加。不施钾时,南雄紫色土的烟草产、质比赤红壤高;含钾丰富的紫色土施钾肥对烟草产量无明显影响,但利于烟草品质提高;含钾中等的紫色土施钾对提高烟草产、质有利。施少量钾肥的效果较好。施钾肥于赤红壤,可明显提高烟草产、质,施多量钾肥效果更佳。施钾肥宜在烟草的旺长初期。

The effects of Myzus persicae damage on the quality of tobaccoleaves were studied in net-room and field respectively in 1987 and 1989.Theresults show 1)There is a variation of the chemical components in aphid inj-ured tobacco leaves.Aphids reduced nicotine,increased total nitrogen,red-uctive sugar,protein and chlorine,but potassium content varied insignifica-ntly in the leaves of plant damdged at seedling stage.The lowest injurylevel(T_1)would increase the content of potassium,the other componentsat vigorous...

The effects of Myzus persicae damage on the quality of tobaccoleaves were studied in net-room and field respectively in 1987 and 1989.Theresults show 1)There is a variation of the chemical components in aphid inj-ured tobacco leaves.Aphids reduced nicotine,increased total nitrogen,red-uctive sugar,protein and chlorine,but potassium content varied insignifica-ntly in the leaves of plant damdged at seedling stage.The lowest injurylevel(T_1)would increase the content of potassium,the other componentsat vigorous growth stage when plant were inoculated with aphids have sim-ilar change tendency to those at seedling stage.2)In addition to suckingthe plant juice,aphids also deposit honey-dew to darken the leaves.Themore aphid injury level,the more aera of the leaf covered with honey-dew.3)Aphids retard the growth and development of the plant,reduce the plantheight,the leaf aera and weight(mg/cm~2),but have no influence on theleaf number significantly except in T_4.Aphids also raise reduce the propor-tion of mid-grade tobacco leaves growing at the middle part of the plant.

1987年和1989年分别在网室内和大田研究了烟蚜为害对烟草品质性状的影响,结果表明,1)烟蚜为害能引起叶片主要化学成分发生变化。苗期接蚜,受害烟草叶片中烟碱含量下降,总氮、蛋白质、还原糖、氯含量升高,钾禽量变化不明显;旺长期接蚜,最低侵害水平(T_1)引起钾含量显著升高.其余成分变化趋势与苗期接蚜相似。2)烟蚜不仅直接刺吸炳草汁液,而且分泌蜜露污染叶片,叶片上蜜露覆盖程度随烟蚜侵害水平增加而提高。3)蚜害导致烟草生长发育不良,受害烟草株高降低,叶而积减小,叶质重下降,但叶片数变化不显著。受害的中部叶片烘烤后中级烟比例下降。
