施肥对无芒雀麦产量影响的研究

FERTILIZER APPLICATION AFFECTING THE YIELD OF BROMUS INERMIS

无芒雀麦是一种喜肥的高产禾草,对肥料反应极为敏感。本试验证明,平均每增施1公斤羊粪、磷酸二铵和尿素,可分别增产鲜草1.04公斤、76.67公斤和60.95公斤。因此,施肥是提高栽培无芒雀麦产量的有效措施。施肥时亩施磷酸二铵以不超30公斤、尿素25～35公斤为宜,过多则不利吸收利用。

Bromus inermis is a high yield grass which likes fertilizer, and it is sensitive to fertilizer, the results show the fresh weight of the grass increased 1.01kg, 76. 7kg and 60.95kg when applying lkg sheep muck,1kg (NH_4)_2HPO_4 and lkg CO(NH_2)_2 respectively, suitable amounts of (NH_4)_2 HPO(?) is 30 kg/ mu, and CO (NH_2)_2 is between 25—35 kg/mu. Excessive fertilizer is difficult to absorpt and use for the grass.
