1993~1995年,通过研究植株经济性状及其相关关系,探讨高寒作物——美国燕麦(AmericanOats)在成都北亚热带地区的生存适应、牧草产量与结实性能.结果表明:美国燕麦基本能适应高温、高湿、少日照的生态条件并正常生长繁殖.各因素中单丛小穗数与产量相关关系极显著(r=0.9765,P<0.01),分蘖数与产量相关关系同样显著.植株日生长量平均0.8145cm.三年中,植株平均分蘖10.2株~11株,牧草干重分别达7345.3kg/hm2、6736kg/hm2和6395kg/hm,种子净干重分别达1393.3kg/hm2、1157.2kg/hm2和1136.6kg/hm2.
From 1993 to 1995, by studying the economic traits of plants and their correlations, the authors discussed the survival adaptation, forage yield and forage performance of the alpine crop, American Oats, in the northern subtropical area of Chengdu. The results showed that American oats could basically adapt to the ecological conditions of high temperature, high humidity and few sunshine and grow normally. Among all the factors, the correlation between the number of spikelets and the yield was significant (r = 0.9765, P <0.01). The correlation between tiller number and yield was also significant. Plant growth on average 0.8145cm. In three years, the average tillers of plants ranged from 10.2 to 11, the dry weight of forage reached 7345.3kg / hm2, 6736kg / hm2 and 6395kg / hm respectively, the net dry weight of seeds reached 1393.3kg / hm2, 1157.2kg / hm2 and 1136.6 kg / hm2.
