Different Methods Of Transplanting Flue-cured Tobacco Growth And Development, Yield And Quality

This test combines the local reality in Guizhou, in order to change traditional farming technique, under the same recruitment amount condition, it is main goals in research to improve fertilizer utilization ratio and tobacco leaf quality, regard Yunyan87 as materials, through the field test, research and analyze ordinary seedling transplanting three transplantation way impact on the field growing situation of the flue-cured tobacco and quality of producing normally deeply, in order to offer certain theoretical foundation for the fact that the abridged edition of the flue-cured tobacco enlarges and produces. The result shows:1. the effect of different transplanting ways on growth and dry matter accumulation of flue-cured tobacco.Different transplanting ways have good facilitation to growth of flue-cured tobacco, in one month of transplanting, because the flue-cured tobacco will carry on the physiology and suit to soil and environment, there is little demand for nutrient, the growth and dry matter accumulation of flue-cured tobacco is not obvious, since transplanting for one month, the flue-cured tobacco demand for the nutrient begins to increase, ridging is planted and obviously strengthened to the growth of flue-cured tobacco and accumulation function of doing the material deeply; The dry matter accumulation amount of T1 and T2 reaches 5% of the prominent levels (r =0.0298),The dry matter accumulation amount of T2 and T3 reaches 1% of the extremely prominent levels (r =0.0012). Ridging can make the organic matter of soil advance ores to impose deeply, promote the growth of flue-cured tobacco, increasing dry matter accumulation amount; For strengthening the flue-cured tobacco absorbability to the nutrient and moisture, improve the quality of upper leaf and yield.2.the effect of different transplanting ways on simple leaf weight, yield and quality.The effect of different transplanting ways on simple leaf weight of lug cutters was not obvious, which on the middle and upper leaf was more obvious. The simple leaf weight of middle and upper of ridging was 4.9% more than normal transplanting and the better-than-average proportion tobacco dealt of ridging was 4.15% and 9.97% than normally, the better-than-average proportion tobacco of ridging of strong sprout was higher than transplanting and normally. It means ridging impose, improve better-than-average rate at tobacco leaf deeply, reduce low-class leaf, raise usability of upper leaf, increase the income of peasant ; Ridging impose deal with increase the production of the range and in weight rise range of simple leaf close deeply at the same time.3. the effect of different transplanting ways on quality of upper leaf.Ridging impose can improve flue-cured quality of upper leaf, ridging impose upper tobacco leaf total nitrogen that deal with content 2.36% - 2.32% respectively, until ridging transplant, deal with (T3) to be 2.59% low normally deeply, and is both up to 1% of the extremely prominent levels with T3; Ridging impose upper tobacco leaf cigarette that deal with alkali 3.51% - 3.47% respectively, until ridging transplant, deal with (T3) to be 4.21% low normally deeply, and has both reached 1% of the prominent levels with T3; The protein content of upper tobacco leaf of dealing with T1, T2 is 10.71% and 11.01% respectively that ridging is planted deeply, until ridging transplant, deal with (T3) to be 11.64% low normally, but each deal with rooms of difference obvious. Prove the ridging ahead of time has better results in reducing the total nitrogen and alkali content of cigarette to impose to adopt the strong sprout deeply, can control the whole nitrogen and cigarette alkali of the upper tobacco leaf, increase the usability of the tobacco leaf, improve the quality of tobacco leaf.4. Flue-cured tobacco abridged edition enlarge technological benefit investigate and analyze.Adopt culture mode that ridging impose deeply, have good supplementary potentiating result of abridged edition. As ridging is planted deeply, it is obvious to deal with the difference between a economic benefits; It is dealt with that ridging is planted deeply though each hectare is put one more into a piece of ridging recruitment expenses than T3, count 300 yuan per Hm~2, but the net income is planted deeply by the ridging of strong sprout dealt with (T2) best, up to 14915 yuan per Hm~2 , raises an increase of 3000 yuan per Hm~2 more than the normal culture (T3); Hm-2, raises an increase of 25.2%; Impose, deal with with general seedling ridging net income fine, raise an increase of 1900 &8226 than normal culture (T3) deeply secondly; Hm-2, raises an increase of 15.9%; T2 is the best choice of giving consideration to yieldt and benefit.
