查询词典 tobacco hornworm

The result would be used in tobacco breeding.4 SRAP technology is used to study the genetic differences among different types of tobacco, including flue-cured tobacco, oriental tobacco, maryland tobacco, burley tobacco, and air/sun cured tobacco, five pairs of primer combinations which can amplify characteristic bands has been screened. Among the five combinations, two of them (SF25*SR2 and SF3*SR26) can distinguish air-cured tobacco including maryland tobacco and Burley tobacco from the other cultivated forms; SF20*SR14 can distinguish sun cured tobacco including oriental tobacco and sun-cured tobacco; SF16*SR14 can distinguish flue-cured tobacco and air-cured tobacco, and SF22*SR14 can distinguish DBJ599 with specisl aroma and the other flue-cured tobacco.5 8 varieties , which represent the different types of tobacco, are divided into 3 groups. I: G-28, II:DBJ599、MD40、By21, III: Basma、Sumsun、XNS、QCT. The cluster analysis result es consistant with experience evatuation.6 Anorthogonal design was used to optimize a ILP-PCR system with 5 factors (DNA, Mg2+, dNTP, primer and Taq polymerase) at 4 levels.The result showed the optimized ILP-PCR system for Nicotiana tabacum L. was: 2uL10×PCRbuffer, 20ng template DNA, Mg2+ 2.0mmol/L, dNTP 150umol/L, primer 0.3umol/L, Taq DNA polymerase 1 U in a total of 20uL reactionsolution.

It was suggest that the yield of tobacco in unit area was significant increasing and the quality was improved along with the altitude increase in Liuyang tobacco area. The tobacco leaves production at the place where the altitude from 400 meter and 900 meter was propitious to postpone the bearing period and growth and development of tobacco plants. It was the base of maturation endurance and could advance the tobacco leave maturation degree of all parts of tobacco plant. And it could hasten the orange tobacco leave ratio of the whole tobacco plant. It was boosted leaves unwrapping of top tobacco plant and the statuses of tobacco leaves, especially the top leaves, were significantly improved. The tissue structure of all parts leaves on tobacco plant were more loosen and the colour and luster of tobacco leaves was more vivid. The nicotinamide content in top leaves were digressive at a certain extent, on the contrary, the contents of the reductive sugar and kalium were increased at different extent. At the same time, it was benefit to play down the pesticide rudimentai of tobacco leaves and increased security of tobacco leaves.

结果表明：在浏阳烟区随着海拔高度的增加，单位面积烟叶的产量有着明显的增加，烟叶质量也有一定程度的改善；在海拔400—900m的地方进行烟叶生产，有利于延长烟株大田生育期，有效缓解浏阳烟区7、8月份的高温逼熟现象，有利于烟株的生长发育，为养好烟株的耐熟性打下良好的基础、促进各部位烟叶成熟度的提高；同时可以有效的促进烟株各部位橘黄烟叶比例的上升，对上部烟叶的开片也有着明显的促进作用，烟叶身份特别是上部烟叶的身份得到明显的改善，各部位烟叶组织结构更加疏松，烟叶色泽更加鲜亮；上部烟叶烟碱含量在一定程度上有所降低，各部位烟叶还原糖、钾含量有着不同程度的增加烟叶香气特征更加明显；香气量有一定程度的增加，吸位更加醇和、余味舒适；同时也有利于减少烟叶的农药残留量，提高烟叶的安全性。

It is conducive to uptake soil nitrogen for flue-tobacco on dryland soil with maize-tobacco rotation before topping (60 days after transplanting) and uptake soil nitrogen for flue-tobacco on paddy soil with rice-tobacco rotation after topping.2 The nitrogen utilization efficiency of rapeseed cake, rice straw and rape straw were 19.5%, 15.5%, 8.1% respectively, and the inorganic fertilizer nitrogen utilization efficiency were 41.1%, 42.7% and 35.7% under the combined application of organic additives and inorganic nitrogen fertilizer. The contribution rate of rapeseed cake, rice straw, rape straw to accumulated nitrogen of flue-cured tobacco were 1.0%, 2.4%, 2.7% respectively by the combined application of organic additives and nitrogen fertilizer. Flue-cured tobacco for organic nitrogen absorption meet with the nitrogen needs laws of high-quality tobacco, indicating that the combined application organic additives and inorganic nitrogen fertilizer reduces the nicotine content of tobacco, an increase of sugar/nicotine ratio and improved the quality of tobacco. In which the role of rice and rape straw is greater than the rapeseed cake can be used as measures to lower nicotine.3 Nitrogen accumulation in flue-cured tobacco with the total nitrogen input was a significant positive correlation during the growth stage of flue-cured tobacco. The total nitrogen input for the 156.3-405.5kg.hm-2, in which the soil nitrogen mineralization capacity account for 22.6%-54.3%, with an average of 34.5%, that is, soil nitrogen mineralization accounted for 1/3 of the total nitrogen input.

旱地轮作土壤有利于烤烟生长前期对土壤氮素的吸收，水旱轮作土壤增加了烤烟生长后期对土壤氮的吸收。2在有机添加物与无机氮肥配施条件下，烤烟对有机添加物中氮的吸收规律基本符合优质烟的需氮规律，其中烤烟对菜籽饼肥、稻草秸秆、油菜秸秆所含氮素的利用率分别为19.5%、15.5%、8.1%，所配施无机氮肥的利用率分别为41.1%、42.7%和35.7%，菜籽饼肥、稻草秸秆、油菜秸秆对烤烟氮素累积量的贡献分别为1.0%、2.4%、2.7%。3不同轮作方式及添加有机物条件下氮素平衡结果显示，烤烟生长期间的氮输入总量为156.3-405.5kg.hm-2，其中矿化氮量为输入总氮量的22.6%-54.3%，平均为34.5%，约为输入总氮量的1/3；肥料氮的利用率为31.4%-42.7%；植烟土壤氮素表观损失率在37.5%-57.2%，平均为46.9%，约为输入总氮量的一半。

According to analyzing the relations between tar content and physical and chemical characters in flue-cured tobacco leaf,some measures of cultivation and flue-curing techniques on reducing tar content were summarized: cultivating and popularizing low tar content of tobacco varieties: increasing the potassium content of tobacco leaf by the adding the application to K fertilization; seizing the proper stage of topping and height and height and suckering in time;far improving the maturity of tobacco leaf; confirming a feasible process of flue-curing; developing and generalizing planting method anything else that could produce low tar content of tobacco leaf.

通过分析烤烟焦油产生量与烟叶的理化特性之间的密切关系，综述了降低烤烟焦油含量栽培调制技术措施：选育并推广焦油量低的烤烟新品种；增施钾肥，提高烟叶含钾量；把握打顶时期和高度，及时除芽；进一步提高烟叶成熟度；确定适宜的烘烤工艺；开发推广低焦油烟叶的其他栽培技术。

In the tobacco production, the measure of only using fertilizers in soil can notimprove the quality of tobacco because soil nutrients releasing is not coincident withthe nutrients absorb rules of tobacco, and the leaf fertilizer with low cost and higheffect can harmonize the nutrients of tobacco leaf and improve the economic benefitof tobacco under assorting with soil fertilizer.

烤烟生产中，由于土壤养分释放状况与烤烟吸肥规律并不一致，单一的土壤施肥并不能达到改善烟叶品质的目的，而成本低、肥效快的叶面肥可以针对烤烟不同生长发育期各异的养分需求特点，配合土壤施肥，协调烟叶自身营养状况，改善烟叶内在品质，进而提高烤烟经济效益。
