摘要
采用大米小麦旱高粱为参试品种,在不同施肥水平下研究其基本性状表现。结果表明,每公顷施用三元复合肥(N:P_2O_5:K_2O=10:8:7)3900kg 以上和尿素1890kg 以上的组合水平,对高梁出苗、苗期和后期发育均产生不良影响;三元复合肥和尿素的公顷施用量低于2100kg 和870kg,则高粱生长弱小,产量下降。因此可以认为,每公顷用复合肥2100-3900kg 和尿素870-1890kg,对高梁的生长发育较为有利。
Rice,wheat and Chinese sorghum were selected as testers in order to study their essential characters based on different standards of applying fertilizers.The result indicates:if to every hectare,we apply 3900kg three-part compound fertilizer (N:P2O5:K2O=10:8:7)and 1890kg urea.they have bad influence on their shooting and,seedling periods and the later growth. If we apply less than 2100kg three-compound fertilizer and 870kg urea,the sorghum grows poorly and its production decreases. So we have concluded it is better for the growth of sorghum to apply 2100-3900kg three-compound fertilizer and 780～1890kg urea.
