化肥减量配施羊粪有机肥对烤烟生长、产质量及土壤养分的影响
Effects of Chemical Fertilizer Reduction Combined with Sheep Manure Organic Fertilizer on Growth,Yield,Quality and Soil Nutrients of Flue-Cured Tobacco
摘要
Abstract
In order to explore the effects of sheep manure organic fertilizer combined with traditional in-organic fertilizer in flue-cured tobacco production,and to provide theoretical basis for rational utilization of sheep manure organic fertilizer in tobacco-growing area of Luoyang,we used Zhongyan101 as material and conducted a plot experiment with equal nitrogen fertilizer amount(60 kg/hm2)in field.Four treatments were set as 100%inorganic fertilizer N(T0),25%sheep manure organic fertilizer N+75%inorganic fertilizer N(T25),50%sheep manure organic fertilizer N+50%inorganic fertilizer N(T50),and 75%sheep manure organic fertilizer N+25%inorganic fertilizer N(T75).The influences of chemical fertilizer reduction combined with sheep manure organic fertilizer on agronomic characters,leaf photosynthetic characteristics,economic traits,quality indexes and soil nutrients of flue-cured tobacco were investigated.The results showed that all the treatments of chemical fertilizer reduction combined with sheep manure organic fertilizer improved the agronom-ic characters and leaf photosynthetic characteristics of tobacco,and facilitated the balanced supply of soil nu-trients and the improvement of soil fertility level.Compared with T0 treatment,the treatments with sheep ma-nure organic fertilizer increased plant height,stem circumference,maximum leaf area,effective leaf number,SPAD value,net photosynthetic rate(Pn),transpiration rate(Tr),stomatal conductance(Gs),and con-tents of soil organic matter,alkaline nitrogen,available phosphorus and available potassium of tobacco at dome stage by 5.49%～8.63%,2.78%～7.46%,0.71%～19.67%,4.82%～9.64%,15.41%～20.42%,21.78%～24.11%,17.05%～24.03%,33.33%～50.00%,13.02%～30.63%,30.08%～68.57%,31.54%～45.51%and 14.67%～20.73%,respectively,and the effects of T50 treatment was the best.The reduction of chemical fertilizer combined with the application of sheep manure also improved the economic properties,the sensory e-valuation quality and the coordination of tobacco chemical compositions.Compared with T0,T50 treatment was the best and increased the proportion of superior tobacco,average price,output value and total sensory quality score of the B2F tobacco leaves by 9.10%,5.36%,7.20%and 4.77%,respectively,and the chemical com-positions of cured tobacco were more coordinate.In summary,under the condition of equal amount of nitrogen,sheep manure organic fertilizer N instead of 50%inorganic fertilizer N was more conducive to growth promo-ting,yield and quality improving,and soil fertility maintaining of tobacco,ensuring the sustainable develop-ment of Luoyang tobacco-growing area.关键词
