Research Of Key Technologies In Amelioration Of Tobacco-growing Soil In Jiangyong Tobacco-growing Areas

From 2007-2009 continuously three years has carried on the Flued-tobacco field soil amelioration two sub-topics Key technologies research in Jiangyong:The Contrast Localization Experimental Study on The Flued-tobacco field winter spare-time planter green manure turns presses & The Field Experimental Study on the Flue-cured tobacco uses Compost Acceleration Fermentation.. The findings are as follows:The Flue-cured tobacco planting area majority is by the tobacco-rice duplicate kind of continuous cropping primarily cropping system.The crop rotation cycle is short,The crops type is unitary. Using fall-winter season land fallow period Plant green manure before mid-October sows seeds. In the moist condition of the soil to carrying on plants sowing seeds of the rapeseed and the perennial ryegrass. To turn green manure presses in the tobacco field before the Transplant about 20 days in the flue-cured tobacco. Afore the period of duratio of the green manure turns presses, it makes no influence on the flue-cured tobacco. The green manure turns presses after in the spoiled solution process to have to consume the ration of the nitrogen and the green manure processing flue-cured tobacco field reduced the fertilizer supply correspondingly, therefore causes the smoke early time growth to come under certain degree influence. But along with green manure spoiled solution completion with nutrition release, it enable a smoke nutrition to obtain the supplement. A mid medium and later part green manure processing smoke growth speeds up, the growth quantity is basic consistent on the comparison,surpasses the comparison generally in the dome time.Green manure processing can enhance the flue-cured tobacco return to original-state sugar content, reduces the content of nicotine& the total nitrogen. The leaf tobacco sugar-nicotine coordination has the enhancement, Perennial ryegrass displays obviously compared to rape processing.The planting of green manure on high produces under the quality premise of the guarantee leaf tobacco can enhance the leaf tobacco chemical composition the coordination, thus is advantageous to the leaf tobacco quality enhancement.Long since time, The flue-cured tobacco field employment Organic fertilizer farm manure belongs to the nature fermentation basically. The nature fermentation method has affected the Organic fertilizer effectiveness and the useing effect. After the use of organic fertilizer increase beneficial mold mushroom spawn centralism fermentation, it can concentrate the thorough fermentation in a short time. Simultaneously causes the organic fertilizer available nutrient content enhancement and the greatest degree reduces the nutrient outflow. Two test point processing and picks compared to the comparison period of duration roasts the time to have the postpone tendency. Along with period of duration advancement, two point processes the promoter action which grows to the flue-cured tobacco strengthens gradually. In dome time the T3 flue-cured tobacco field growing trend obviously is higher than the comparison, T3 the promoter action which grows to the flue-cured tobacco surpasses T2 obviously. Each processing respectively to plant disease occurrence has not displayed the obvious influence.Two processes to the flue-cured tobacco economical character has universally enhances the tendency, it's obvious to the output value and the superior smoke rate enhancement function. Between two processing compares, the T3 economica-character surpasses T2 obviously. Among the Processing and the comparison compares, the total sugar content has reduces.the nicotine content has the ascension tendency, the sugar-nicotine compares along with it has reduces.In consideration of leaf tobacco quality and under chemical composition coordinative premise,The control of the organic fertilizer fermentation degree and the suitable amount used is extremely essential.
