摘要
采用盆栽法研究了施氮时期对玉米鲁单50饲用营养价值的调控作用。结果表明,施氮肥处理玉米的生物产量、籽粒产量以及饲用营养品质都显著的高于不施氮肥的。拔节期一次性施用氮肥可以获得较高的生物产量,有利于提高玉米作为青饲(贮)饲料的营养价值;拔节、大口(或开花)期,2或3次施氮肥有利于提高粮饲兼用玉米的饲用营养价值。
An experiment was conducted on effect of nitrogen which nutritive value at different stage and physiological characteristics of potted planting maize(Ludan50)Results showed:whole biomass at different stage plant,kernel yield,and nutritive value of all treatments were significant higher than those without fertilizing nitrogenApplying nitrogen could gain a high biomass at the joint stage for one timeand improve maize nutritive value fertilizing,two times at flowering
