| Averagely | 15.99 | 15.54 | 16.43 | 13.10 | 12.66 |
From Figure 21 and table 21 as can be seen that sugared alkali ratio, with leaves remained 22,20>18,2, pasture test site is basic with seeking
Unanimously, sugared alkali ratio can be improved more than leaves remained, from the point of view of numerical characteristics, this is unfavorable to the harmony of chemical composition；From screening
From the point of view of rain opportunity, on stone forest, Zhao is completely the same with Xun Dian base pilot, and that is, rain cover can reduce too high sugared alkali ratio, to Nicotiana tabacum L. product
Matter is favourable.
Brief summary：Comprehensive analysis show, optimal to start rain cover from August 1 day, can increase Nicotiana tabacum L. ether extract content, fall
Low content of starch, sugared content and two sugar are poor, increase the content of nicotine and total nitrogen, and sugared alkali ratio converts to favourable direction, with top
Nicotiana tabacum L. performance is substantially.Leaves remained is suitably to stay leaf less（18～22）It is advisable, and leaves remained is more can improve sugared alkali ratio, from numerical value
From the point of view of unfavorable to quality；Leaves remained I haven't seen you for ages improve ether extract, favourable to quality.
In sum：（1）Suitably rain cover is favourable to quality of tobacco, and after being pinched within 1st with August, about 10d plays beginning rain cover
Good, Nicotiana tabacum L. ether extract content can be increased, reduction content of starch, sugared content and two sugar are poor, and sugared alkali turns than to favourable direction
Change；（2）K326 quality is advisable for 19～20 with leaves remained, that is, be conducive to improving Nicotiana tabacum L. ether extract content, be also beneficial to reduce
