块根作物品种适应性比较试验

Comparative Tests on Adaptability of Several Varieties in Root Tuber Crops

2014年至2015年,以8个块根品种为试材,在贵州省兴仁县放马坪种羊场开展了品种比较及丰产栽培比较试验,并且对放马坪土壤养分进行了测定。试验采用随机区组设计和大田种植相结合,对各品种的物候期、植株性状、营养成份、鲜草产量和种子产量等指标进行综合评价,以筛选出适宜放马坪种植的块根多汁饲料作物。结果表明:威宁芜菁甘蓝(绿皮)、花溪芜菁甘蓝综合性状优良,鲜草产量分别高达6 127.7kg/667 m^2和6 085.8kg/667 m^2,种子产量分别是106.5kg/667 m^2和118.7kg/667m^2,威宁芜菁甘蓝(绿皮)和花溪芜菁甘蓝是弥补其冬季饲草料短缺的主要种植品种。同时,威宁芜菁甘蓝(绿皮)和花溪芜菁甘蓝也可作为贵州相似地区冬季饲草料的参考品种。

Comparative varieties and high -yield cultivation tests was conducted in 2014 and 2015. The materials was composed of 8 root tuber crops in this study. The field trial was located at Fang Ma Ping of Xingren county in Guizhou Province. Soil nutrients of this field were also measured and analysed in 2014 and 2015. The trial was planted in the combination of randomized block design and field planting. Phenophase, plant trait, nutritional ingredients, fresh biomass yield and seeds yield were measured based on 8 varieties to select succulent root fodder crops which were suitable for locally grown conditions, The results showed 1 ） Rassica napobrassica L. Mill. cv. Weining and Rassica napobrassiea L. Mill. cv. Huaxi exhibited excellent comprehensive performance, 2） fresh biomass yield of Rassica napobrassica L. Mill. cv. Weining and Rassiea napobrassica L. Mill. cv. Huaxi were up to 6127. 7 kg/mu and 6085. 8 kg/mu respectively, 3 ） seed yield of Rassica napobrassiea L. Mill. cv. Weining and Rassica napobrassiea L. Mill. cv. Huaxi were 106. 5 kg/mu and 118. 7 kg/mu respectively. The results revealed Weining （green） and Huaxi as main planting varieties covered the shortage of feed insufficient in cold season and extending potential varieties in other Similar regions in guizhou.
