摘要:
以大麦品种垦脾2号为试验材料，在黑龙江省大麦主产区设置不同施氮水平和不同施氮方式试验，研究了氮肥对大麦养分吸收特性及产量的影响，旨在为实现大麦高产、优质、高效、可持续生产施肥技术体系提供科学的理论依据。结果表明：在该地区N120 kg·hm-2、P20590 kg·hm-2、K2O 90 kg·hm-2是最佳的用量，产量达到4 957 kg·hm-2；全部磷钾肥+50%氮作基肥，30%氮作种肥，20%氮作分蘖肥是最佳的施肥方式。从整个生育时期来看，在大麦植株的茎和叶中，氮磷钾养分含量随着生育时期的推进逐渐减少，而在穗中氮磷钾养分含量变化没有规律性。
Abstract:
Taking the barley variety of Kenpi No.2 as experimental material,the effects of different dosage and way of nitrogen on the nutrient absorption character and yield of barley were studied to offer scientific theory to realize the technique of fertilization on barley high yield and quality and efficient sustainable production.The results showed the fertilizer of N120 kg·hm-2,P2O590 kg·hm-2,K2O 90 kg·hm-2 was the best dosage,the yield was 4 957 kg·hm-2,the best way of fertilization was all P、K and 50% N as base fertilizer,30% N as seed fertilizer,and 20% N as tillering fertilize.In the whole growth period,the N、P and K content in stem and leaf reduced as propeling of growth of barley,while there was no regularity in spikes.
