摘要
以白燕7号燕麦为材料,研究了不同配比的N肥和K肥对燕麦生长特性(有效分蘖、茎粗、叶面积、穗长)和鲜草产量的影响。结果表明:施N和施K对有效分蘖、茎粗、叶面积、穗长都有显著的影响(P<0.05),随着施肥量的增加呈先增后降的变化趋势;鲜草产量在不同生育时期随着施N量的增加而增加,随着施K量的增加呈先增后降的变化,其中N100K105的增产效应在施肥处理组合中最佳。
Bai yan No. 7 oat was used as experiment materials. The effect of applying N, K complex fertilizer （ different ratio ） on oats growth characteristics and fresh forage yield had been studied, （ tiller, stem width,leaf areas, the length of spike）. The results showed that inputting N,K fertilizer had significant effect on tiller, stem width, leaf areas, the length of spikd （P 〈 0.05 ）. The change trend was from increasing to decreasing with increasing applying fertilizer. Fresh forage yield increased with increasing applying N in different growth stage and fresh forage yield changed form increasing to decreasing with increasing applying K.N100K105 is optimum in whole treatment of applying fertilizer.
