1、施氮和耕作方式对红麻福红992农艺性状和产量的影响-农学论文施氮和耕作方式对红麻福红992农艺性状和产量的影响宋岩1,王道波1,刘永贤2(1.北京航空航天大学北海学院,广西北海536001;2.广西农业科学院,南宁530007)摘要:以红麻(HibiscuscannabinusL.)的常规栽培品种福红992为例,探讨不同施氮和耕作方式对红麻生长发育和产量形成的影响,为红麻高产高效栽培提供合理的施肥和耕作依据。通过大田试验,研究了施氮和耕作方式对福红992农艺性状和干物质积累的影响,试验设3种耕作方式,即免耕、垄耕和深松耕(粉垄);3种施氮
2、方式,即T1(20%作基肥,80%作追肥),T2(40%作基肥,60%作追肥)和T3(60%作基肥,40%作追肥)。结果表明,与免耕相比,深松耕的生麻产量、种子产量和地上部干质量分别增加15.1%、14.9%和14.5%,差异显著;与T1相比,T2生麻产量、种子产量和地上部干质量分别增加9.9%、30.3%和15.1%,差异显著;免耕和垄耕时,T2株高、皮厚、茎粗和生麻产量、种子产量、地上部干质量均达到最大值;深松耕时,T1株高、皮厚、茎粗和生麻产量、种子产量、地上部干质量均达到最大值。研究表明,深松耕T1时,生麻产量和种子产量同时达到最
