不同硫水平区硫素施用量对烤烟硫素利用及产质量的影响
Effects of sulfur application rates on sulfur utilization,yield and quality of flue-cured tobacco in regions with different sulfur levels
摘要
Abstract
[Objective]The study examined the effects of sulfur application rates on sulfur utilization,the yield and quality of flue-cured tobacco in regions with different background soil sulfur levels,analyzed the relationship between sul-fur content in tobacco leaves and sulfur application rates,evaluated the absorption and utilization efficiency of sulfur in flue-cured tobacco to provide scientific basis for rational sulfur fertilization and high-quality tobacco production.[Method]A two-year field experiment was conducted in typical sulfur-deficient(available sulfur content 6.25 mg/kg),potential sulfur-deficient(available sulfur content 16.03 mg/kg),and sulfur-sufficient(available sulfur content 26.55 mg/kg)flue-cured tobacco growing regions in Nanping,Fujian.Different sulfur application levels(S1:30.0 kg/ha;S2:60.0 kg/ha;S3:90.0 kg/ha)were applied with no sulfur application(CK)as a control.Sulfur contents in different parts of flue-cured tobacco under different treatments were measured,and sulfur accumulation and fertilizer use efficiency were calculated.After flue-curing,tobacco output value were assessed,and middle leaves(C3F)were selected for chemical composition analysis and sensory quality evaluation.[Result]Compared with CK,sulfur application could increase the sulfur content of tobacco leaves.In the sulfur-deficient and potential sulfur-deficient regions,the S3 treatment showed fine effects,with an increase of 12.75%-30.62%and 31.45%-36.52%respectively.In the sulfur-sufficiency region,the S2 treat-ment showed fine effects,with an increase of 8.71%to 16.30%,the increase reached significant level(P<0.05,the same below).Sulfur application significantly increased the flue-cured tobacco total sulfur accumulation(6.11%-25.04%)and tobacco leaf sulfur accumulation(7.79%-37.19%)in the 3 experiment fields.In the sulfur-deficient and potential sulfur-deficient regions,the S1 treatment had the highest apparent utilization rate of sulfur fertilizer(RE),sulfur agro-nomic efficiency(AE),and sulfur partial productivity(SEP).In the sulfur-sufficient region,the SEP under S1 treatment was the highest,and there was significant difference between treatments.The S2 treatment showed the highest total potas-sium content in flue-cured tobacco leaves in both sulfur-deficient and potential sulfur-deficient regions,significantly in-creasing it by 11.68%-16.52%compared to the CK.The sensory quality of flue-cured tobacco was the best under the S1 treatment in sulfur-deficient and potential sulfur-deficient areas.However,in the sulfur-sufficient area,sulfur application reduced the sensory quality of the flue-cured tobacco.In sulfur-sufficient region,the relationship between sulfur applica-tion rate and the total potassium content in flue-cured tobacco followed a quadratic equation curve.The total potassium content reached its maximum value when the sulfur application rate was 30 kg/ha.[Conclusion]In the tobacco-growing areas of Fujian,a sulfur application rate of 30-60 kg/ha is recommended for sulfur-deficient and potentially sulfur-deficient regions,while sulfur input should not exceed 30.0 kg/ha in sulfur-sufficient regions.In addition,the current structure of potassium fertilizer application in flue-cured tobacco production should be adjusted in a timely manner,with a reduced use of potassium sulfate.关键词
