不同水肥一体化模式在烤烟生产中的应用效应
Application Effects of Different Designed Fertigation Pattern in Flue-cured Tobacco Production
【摘要】 为寻求适合烤烟生产应用的水肥一体化水肥管理模式,开展不同水肥一体化模式在烤烟生产应用效应的研究。结果表明,与常规施肥灌溉模式相比,试验所设计的水肥一体化模式不仅能够显著促进烟株生长发育,促进烟株对钾素和干物质的积累,同时还能显著提高烟叶的产量和产值,以模式T1和T3应用效益最突出。综合T1和T3模式的水肥设计参数,全生育期总施氮量为165 kg/hm2,基追比为4∶6,还苗期和伸根期追施总追氮量的15%;N∶K2O为1∶1,旺长期和成熟期分别追施总追氮量的70%和15%;N∶K2O均为1∶3可作为烤烟水肥一体化技术的水肥管理模式应用于烤烟实际生产中。
【Abstract】 In order to find the appropriate fertigation pattern in flue-cured tobacco production,different flue-cured tobacco fertigation pattern were designed and put into used in order to find out its application effects on tobacco production.The result showed that all designed fertigation pattern especially pattern T1 and T3 could not only stimulate the growth of tobacco,increase the potassium and dry matter accumulation,but also enhance the yield and output value.Based on the design parameter of T1 and T3,165 kg/hm2 act as the total nitrogen application rate,4∶6 act as dressing ration,the topdressing accounted for 15% of total nitrogen topdressing amount in transplanting seedling stage, root extending stage,and N :K2O respectively act as 1∶1,1∶3.1∶3 can be considered as the reference model of fertigation pattern used in flue-cured tobacco production.
