摘要
2000-2001年在新疆塔里木农垦大学牧草试验站进行了施氮肥对交战高羊茅种子质量和产量组成影响的研究。结果表明,施氮可以明显提高种子的活力和质量,并增加了单位面积的生殖枝数和小花数/小穗;施氮肥提高了种子产量,其中以秋季60kg/hm2+春季120kg/hm2施氮量为最好,种子产量可达1653.9kg/hm2。
A field study was conducted at the Xinjiang Talimu Agricultural Reclamation University Herbage Experimental Station on the effect of nitrogen fertilizer application on seed quality and yield components of tall fescue during 2000-2001. The results indicated application of nitrogen fertilizer can significantly raise seed vigor and quality, and increase seedheads/m^2 and florets per spikelet. Tall fescue seed yield was significantly increased with nitrogen fertilizer application. The optimal application of nitrogen was 180 (kg/hm^2) (60 (kg/hm^2) in autumn + 120 (kg/hm^2) in spring), with seed yield reaching 1 653.9 (kg/hm^2).
