- 摘要:
- 以“青引1号”燕麦和箭筈豌豆为试材,研究了不同燕麦+箭筈豌豆混播比例和施肥量对燕麦农艺性状、产量、品质等的影响,以期为燕麦在高寒地区的高效栽培和合理施肥提供参考依据。结果表明:对10 个性状进行主成分分析,得出累积贡献率达到89.12%的3个主成分因子;对各处理的主成分得分和综合得分值分析表明,燕麦+箭筈豌豆混播比例4∶1+120 kg?hm-2(N)综合得分最高,较其它处理具有较高的株高(133.03 cm)、穗长(18.36 cm)、单株茎质量(8.12 g)、单株叶质量(1.25 g)、叶茎比(0.154)、鲜草产量(30 330 kg?hm-2)、干草产量(13 267 kg?hm-2)、鲜干比(2.29)、粗蛋白质含量(14.39%)和较低的灰分含量(2.91%)。说明燕麦+箭筈豌豆混播比例4∶1+120 kg?hm-2(N)是当地最适宜的牧草栽培群落结构和施肥方式。
- Abstract:
- ‘Qingyin 1’ oat and vetch were used as test materials,a field experiment was conducted to research the effect and evaluate of different mix sowing rates of oat-vetch and nitrogen fertilizer rate on agronomic characteristics,yield characteristics and quality characteristics,in order to gain a theoretical basis for oat efficient cultivation and reasonable fertilization in alpine region.The results showed that principal component analysis was applied to the 10 involved characteristics and the contribution rate of three principal component factors reached to 89.12%.Mix sowing rates of oat-vetch 4∶1 and 120 kg?hm-2 nitrogen application was the most suitable treatment,with the highest principal component score and integrated score.It had higher for plant height(133.03 cm),ear length(18.36 cm),stem weight per plant(8.12 g),leaf weight per plant(1.25 g),leaf stem ratio(0.154),fresh forage yield(30 330 kg?hm-2),hay yield(13 267 kg?hm-2),fresh-dry ratio(2.29),crude protein content(14.39%) and lower ash content(2.91%).It showed that mix sowing rates of oat-vetch 4∶1 and 120 kg?hm-2 nitrogen application was the most pasture cultivation community structure and fertilization method for local cultivation.It provided a theoretical basis for oat efficient cultivation and reasonable fertilization in alpine region.
