摘要
为探讨成都平原地区燕麦(Avenasativa)的高产栽培措施,以“英迪米特”燕麦为研究材料,采取3个播期、4个播量的双因素完全试验设计,研究不同播期、播量对其干草产量、株高、茎叶比和倒伏率的影响。结果表明:播期对“英迪米特”燕麦的茎叶比、株高和倒伏率有显著影响(P<0.05),3个播期中,早播处理下的茎叶比最小,然而其倒伏率最高;中播处理下的株高最高,然而其茎叶比最大;与之相比,晚播处理最为合理。播量对“英迪米特”燕麦的干草产量有显著影响(P<0.05),当播量为90kg·hm–2水平时,燕麦干草产量最高,显著高于60、120、150kg·hm–23个水平下的干草产量(P<0.05)。对“英迪米特”燕麦在不同播期、播量下的饲草产量及相关性状的表现综合分析,在成都平原地区进行燕麦种植时,播期以晚播处理,播量以90kg·hm–2为最佳。
To explore the high-yield cultivation measures of ‘Intimidator’ oats (Avena sativa) on the Chengdu Plain, a twofactor complete experimental design with three planting dates and four planting rates was set up to study the effects of different dates and rates on the hay yield, plant height, stem-leaf ratio and lodging rate of ‘Intimidator ’ oats. The results showed that the planting date had a significant effect on the stem-leaf ratio, plant height, and lodging rate (P < 0.05). Among the three planting dates, the stem-leaf ratio and leaves under the early planting treatment were the smallest, but the lodging rate was the highest. Additionally, the plant height under the middle planting treatment was the highest, but the stem-leaf ratio was the largest;In comparison, the late planting treatment was the most reasonable. Planting rate had a significant effect on the hay yield of ‘Intimidator’ oats (P < 0.05). When planting rate was 90 kg·hm–2, the hay yield of oats was the highest, significantly higher than 60, 120, and 150 kg·hm–2 (P < 0.05). A comprehensive analysis of the forage yield and related traits of ‘Intimidator’ oats on different dates was conducted. When the oats were planted in the Chengdu Plain, the best conditions were a late sowing date, and a sowing amount of 90 kg·hm–2.
