摘要
以红麻(Hibiscus cannabinus L.)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高。
To provide reasonable basis for cultivation of kenaf（Hibiscus cannabinus L.） with high yield, Fuhong 992 was used to study the effects of different tillage methods and fertilization methods. Three tillage methods including no tillage, ridge tillage and sub-soiling tillage（Fenlong） and three fertilization modes including, i.e. T1（20% N fertilizers as basal fertilizer and 80%N fertilizers as topdressing）, T2（40% N fertilizers as basal fertilizer and 60% N fertilizers as topdressing）, T3（60% N fertilizers as basal fertilizer and 40% N fertilizers as topdressing） were conducted. The results showed that compared with no tillage,sub-soiling tillage increased fiber yield, seed yield and shoot dry mass of Fuhong 992 by 15.1%, 14.9% and 14.5%. Compared with T1, T2 increased fiber yield, seed yield and shoot dry mass of Fuhong 992 by 9.9%, 30.3% and 15.1%. In no tillage and ridge tillage, plant height, stem diameter, thickness, fiber yield, seed yield, shoot dry mass reached the maximum with T2. In sub- soiling tillage, plant height, stem diameter, thickness, fiber yield, seed yield, shoot dry mass reached the maximum with T1. Fiber yield and seed yield reached the maximum at sub-soiling tillage with T1.
