摘　　要：采用随机区组排列法,进行了氮肥不同施用量对高粱白杂8号生长发育和产量的影响试验。结果表明,增加氮肥施用量可促进白杂8号高粱产量增加,在施用P_2O_575 kg/hm^2、K_2O 75 kg/hm^2的条件下,施纯N 300 kg/hm^2较不施用氮肥增产5.9%。同时,增加氮肥施用量对高粱千粒重影响较大。Using random block arrangement,the effects of different amounts of nitrogen fertilizer on growth and yield of sorghum Baiza 8 were studied in this paper.The results showed that increasing the amount of nitrogen fertilizer could promote the increase yield of Baiza 8.Under the conditions of 300 kg/hm^2 nitrogen fertilizer,P2O5 75 kg/hm^2 and K2O 75 kg/hm^2,the yield increased by 5.9% compared with that of non-applied nitrogen fertilizer.It had a great influence on grain of sorghum.
