【摘要】 通过5因素混合正交组合试验,对新麦草种子生产管理措施进行了研究。结果表明:影响新麦草种子产量和质量(活力指数)最重要的管理因素是收获后灌溉时间,影响的第二位是收获后刈割残茬;影响种子活力指数的第二位是行内疏枝。新麦草种子生产收获后优化管理组合为:(九月灌+11月灌)+不疏枝+次年春季施肥+收获后刈割残茬+不火烧残茬。更多还原

【Abstract】 Based on quintic-factor orthogonal designed field experiment,the study on seed post harvest managements on Psathyrostachys juncea Nevski was conducted.The results showed that irrigation time after seed harvest is the most productive factor for the seed yield and the seed vigor index,time of cutting residue comes next for the seed yield,whereas density manipulation is next for the seed vigor index;It is suggested that irrigation in Sep.and Nov.respectively,applied fertilizer in spring,cutting residue in July and not burning the residue for post-harvest management on seed production of Psathyrostachys juncea Nevski.is the optimal managent combination.更多还原
