Experimented Study And Popularization Of Organic-inorganic Specialty Compound Fertilize For Tobacco

Current tobacco fertilizer application in China is most inappropriate District tobacco smoke further improve the quality of the main limiting factor,Tobacco production in the low utilization rate of fertilizers,quality tobacco not "quality fitness production" requirements,Against Tobacco production of nitrogen,phosphorus and potassium nutrients large separate application,the impact of improved quality flue-cured tobacco production,How to improve fertilizer efficiency,enhance quality and improve tobacco soil environment is to improve the quality of the tobacco leaves key issues,To vigorously promote organic-dedicated tobacco mixture of inorganic fertilizer.Adopted in 2006,2007 in Kaiyang County,Longgang Town tobacco Technology Demonstration Garden in tobacco mixture of organic and inorganic fertilizer test and demonstration promotion,The results show that:Organic and inorganic mixed fertilizer for tobacco processing specialty fertilizer than conventional tobacco processing advance into the squaring stage,the harvest period,and agronomic traits is superior to conventional tobacco specialty fertilizer processing,From transplanting after 50 days to 70 days, Organic and inorganic mixed fertilizer for tobacco processing plant height than conventional tobacco specialty fertilizer handling growth of 27.6 cm,respectively,to a very significant difference;That leaves mature,the number of tobacco leaf tobacco specialty fertilizer than conventional treatment more than 2.4,From transplanting after 30 days to the transplant after 70 days,specialty fertilizer than conventional tobacco the leaf area increased by 92.55 cm2.Organic and inorganic mixed fertilizer dedicated inorganic fertilizer mixed fertilizer than conventional tobacco exclusive pre more developed root system,strong vitality,a large quantity of nitrogen absorption,absorption peak early,Nitrogen nutrient absorption ahead seven days,a substantial absorption of nitrogen ahead eight days,shortens the duration of the 11 days;The dry matter accumulation in advance seven days,and accumulation increased,aboveground,underground Department has been higher than that of conventional dry matter accumulation tobacco specialty fertilizer,The latter part of the soil nitrogen effective than conventional tobacco specialty fertilizer processing less 17mg/kg,to a very significant level,a significant benefit of early mineralization of soil nutrients.Total sugar content than onventional tobacco specialty fertilizer increased by 1.19 percentage points;Shi Muke value,sugar alkali more reasonable,and nicotine,total nitrogen,protein tobacco specialty fertilizer than conventional low.Organic-mixtures of inorganic fertilizer for tobacco production,average price,the per- Chinese acre yield value,the proportion of middle-smoke tobacco specialty fertilizer than conventional treatment were increased by 16.6 kg/666.7m2,1.29 Yuan/kg and 372.02 Yuan/666.7 m2,4.Three percentage points per Chinese acre will increase farmer's income 272.02 Yuan,significant social and economic benefits.This paper due to long-term settlement of a single application of fertilizer on the soil of trace elements in tobacco reduction,reduced fertilizer use,soil nutrient imbalance in the ratio of the problem,and the utilization of Soil and Fertilizer,trace elements have been improved,with the nutrient status of flue-cured tobacco on nutritional needs.
