Table one different transplanting method compares breeding time
As can be seen from table one, the transplanting method that this specific embodiment relates to and conventional transplanting method are being transplanted on the same day, the cigarette seedling that the transplanting method that this specific embodiment relates to is transplanted does not go back seedling stage, after transplanting, tobacco root system directly contacts with the water of hole surrounding, fertilizer and soil, cigarette seedling directly grows, cigarette seedling contains more chlorophyll (as shown in Figure 1) in growth early stage, and then promotes cigarette seedling early growth and quick tiller.
Be conducive to the early growth and quick tiller of cigarette seedling.Conventional transplanting method has the also seedling stage of 7 days, is unfavorable for the early growth and quick tiller of cigarette seedling.
Compare the breeding time that transplanting method that the present embodiment relates to and conventional transplanting method transplant tobacco seedling growth by experiment: this transplanting method all than conventional transplanting method in advance, especially roasting phase beginning is adopted, be advanced by 5 day time, so substantially just a canopy tobacco leaf can be baked in advance, thus can effectively avoid autumn wind cold dew arrival upper back tobacco leaf be difficult to toast a difficult problem, have larger facilitation to the production of mountain region tobacco leaf.
The different transplanting method of table two is at different times economical character comparison sheet
Tobacco leaf economical character is the important indicator weighing cigarette strain growing way quality.
As can be seen from table two, the flue-cured tobacco of the transplanting method plantation adopting the present embodiment to relate to all is better than the economical character of the flue-cured tobacco adopting conventional transplanting method to plant at the economical character of different growing.Wherein, the flue-cured tobacco of transplanting method that the present embodiment relates to plantation has obvious advantage in plant height, leaf length, Ye Kuan, the number of blade and stem girth, and can illustrate that it has and grow fine, and stem stalk is sturdy, the feature of cigarette strain disease resistance and strong stress resistance.
In addition, through Germicidal efficacy, when the transplanting method adopting the present embodiment to relate to transplants cigarette seedling, three people one group, share out the work and help one another.Three people punch respectively, put cigarette seedling, drench normal root water, do not need after transplanting to put a lodged plant upright, three people's coordinated one day can plant 3 to 4 mu, owing to being with water, being with fertile cigarette shoot survival percent high, be with medicine to make the soil insects such as cutworm sting food cigarette strain phenomenon seldom to occur, transplanting terminates rear seedling of substantially need not looking into and fills a vacancy, and greatly reduces and manually fills the gaps with seedlings.In addition, cigarette seedling growing way neat and consistent.Conventional transplanting method only can transplant 0.5 mu for each person every day, and it is not good to move effect after planting, and cigarette shoot survival percent is not high, and cigarette seedling lacks nest phenomenon ubiquity, and phenomenon of manually repeatedly filling the gaps with seedlings happens occasionally, and cigarette seedling regularity is poor.
Therefore judge through specific experiment contrast, the transplanting method that known the present embodiment relates to, not only subtract work and fall this, transplanting progress is enhanced about more than once, and transplants quality also higher than routine transplanting, can effectively alleviate tobacco grower's labour intensity, reduce and transplant link recruitment cost, improve kind of a cigarette benefit.In addition, the transplanting method that the present embodiment relates to deeply is planted under carrying out seedling, aperture, band water, band fertilizer, band medicine and mulch film, and to transplanting the less demanding of weather, no matter fine day drought impact is little, and cigarette seedling can be incubated in opesium cave, ground, rains and can retain and conserve soil moisture.But conventional transplanting method is comparatively large by weather effect, the especially survival rate that will have a strong impact on after cigarette transplantation of seedlings of dry weather.Therefore, applying of the transplanting method that the present embodiment relates to, this is fallen in the work that subtracts for realizing leaf tobacco production, and certain contribution is made in upgrading synergy.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, any content not departing from technical solution of the present invention, the any amendment done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all still belong to the scope of technical solution of the present invention.
