Effect Of Biochar Mixed With Inorganic And Organic Fertilizer Application On Soil Properties And Yield And Quality Of Tobacco

Because of long-term use of soil fertilizers, soil fertility declined, as demonstrated bysoil compaction, moisture content decreases. At present, the domestic researchbiochar as soil conditioner less, especially mixed with cake fertilizer and otherorganic fertilizer research less. In this experiment, biochar as a soil conditioner, wereset four treatments: control, biochar+fertilizer, fertilizer+cake, biochar+fertilizer+cake, to study biochar mixed with inorganic fertilizer application on soil physical andchemical properties of organic and the growth and quality of tobacco.(1) biochar mixed with inorganic and organic fertilizer application on soil availablenutrientsBiochar mixed with inorganic and organic fertilizers applied in the tobacco grown inthe same period, added soil nitrogen treatment biochar, available K, available P levelsare higher than the control, add organic carbon content is also higher than the controlbiochar this shows biochar organic fertilizer mixed with inorganic fertilizerapplication can delay the release of nutrients to ensure tobacco nutrients needed forgrowth, reducing fertilizer leaching; adding biochar to soil pH can play a bufferingeffect, to ensure that tobacco growing need alkaline environment.(2) biochar mixed with inorganic and organic fertilizer application on soil bulkdensity Biochar mixed with inorganic and organic fertilizer application can play a rolein reducing soil bulk density, but biochar+cake fertilizer and fertilizer handling no more than biological treatment to reduce carbon+more fertilizer, explains biocharmixed with organic fertilizer application does not play a role in further reducing soilbulk density.(3) Biochar mixed with inorganic and organic fertilizer application on rootdevelopment of tobaccoBiochar mixed with inorganic and organic fertilizer application can increased theaccumulation of tobacco belowground biomass and biochar mixed with cake fertilizerapplication can play a further effect of promoting biochar mixed with inorganic andorganic fertilizer application can increase tobacco shoot ratio, improved root vigor,root volume and root dry and fresh than illustrated the added biochar in soil for rootdevelopment can indeed play a positive role, and mixed with organic fertilizerapplication can play further promoting effect.(4) biochar organic fertilizer mixed with inorganic fertilizers on physiologicalcharacteristics of flue-cured tobacco during the growth of tobaccoBiochar mixed with inorganic and organic fertilizers can be applied to tobaccoaboveground biomass accumulation played a role in promoting and biochar mixedwith organic fertilizer can be applied to further promoting the accumulation ofaboveground biomass of tobacco, but for tobacco growing process reducing sugarcontent, total sugar, total nitrogen content no obvious promotion effect, but therewas a certain nicotine content promoting effect, we can not raise tobacco potassiumcontent in the growth process, but can delayed the release of cake fertilizer fertility,promoted post-potassium tobacco improve the content.(5) biochar mixed with inorganic and organic fertilizer application on the chemicalcomposition of conventional roasted smokeBiochar mixed with inorganic and organic fertilizers applied on the lower leaf starchcontent, nicotine content, no significant effect, but reduced the sugar content of thelower leaves, the total sugar content, potassium content, chlorine content, totalnitrogen content, from both sugar ratio, ratio of nitrogen bases of view, and not onhow to improve quality and lower leaf tobacco; biochar mixed with inorganic andorganic fertilizers applied to improve the central leaf sugar content, total sugar content, total nitrogen content, reduced the nicotine content, starch contentpotassium content, no significant effect on chlorine content, but more than twosugars, nitrogen bases than the view, T2processing performance was the bestdescribed biochar and cake fertilizer mixed fertilizer did not play further buffs;biological carbon and inorganic and organic fertilizers mixed application can improvethe upper leaf sugar content, total sugar content, nicotine content, no significanteffect on the total nitrogen content, chlorine content, reducing the potassium contentand starch content, from both sugar ratio, ratio of nitrogen bases, the biochar mixedwith inorganic and organic fertilizers applied on the upper leaf tobacco notsignificantly improve the quality of the role.(6) biochar mixed with inorganic and organic fertilizer application on the roast smoke(C3F) neutral aroma constituents influenceBiochar mixed with inorganic fertilizer application could increase further promote thedegradation of phenylalanine grilled amount of tobacco products, the total amount ofbrown reaction product, the total carotenoid degradation products, but biochar mixedfertilizer and did not play in Cake the effect of biochar mixed with inorganicfertilizers can be applied to improve the content of tobacco solanone after baking, andcake fertilizer mixed application can be further improved solanone content, biochar ismixed with inorganic fertilizer can increase the content neophytadiene, but biologicaland inorganic carbon mixed application of organic fertilizer has reduced the contentof the roasted tobacco neophytadiene, except neophytadiene, the other componentsof the total aroma of view, adding biochar can increase the amount of tobacco aromaafter baking, but the cake fertilizer mixed with biochar play no further facilitiespromoting effect.(7) biochar mixed with inorganic and organic fertilizer application on the roastpetroleum ether extract of tobaccoBiochar mixed with inorganic fertilizer application can increase the content ofpetroleum ether extract lower leaves, but did not play with the cake fertilizer mixedfertilizer further promoting effect; biochar mixed with inorganic and organicfertilizers can be applied to improve the middle and upper leaves leaf petroleum ether extract content, indicating that biochar fertilizer mixed with cake fertilizer applicationcan increase the petroleum ether extract of tobacco content.(8) biochar organic fertilizer mixed with inorganic fertilizers on tobacco economictraitsBiochar mixed with inorganic and organic fertilizer application can increase the valueof tobacco production and improve the quality tobacco smoke and fine proportions,indicating that biochar mixed with inorganic and organic fertilizers applied toimprove tobacco promotion of economic traits have some effect.
