延安不同菊芋品种比较试验研究

筛选出适宜延安种植的菊芋品种,解决延安菊芋品种单一的问题,促进延安菊芋产业化发展。对引进的6个菊芋品种和1个当地品种进行田间比较试验,调查各品种田间的生育期、农艺性状和经济性状。试验结果表明,‘廊芋1号’和‘廊芋2号’2个品种的综合性状表现较好,其产量分别为57378.68、56228.10 kg/hm²,较对照增产分别为5.11%、3.00%。其余品种表现一般,产量均低于对照品种,需继续试种观察。 ‘廊芋1号’和‘廊芋2号’较适合在延安种植,可进行示范推广。

Comparative Analysis of Helianthus tuberosus Varieties in Yan’an

The suitable varieties of Helianthus tuberosus for planting in Yan'an were screened out to solve the problem of single variety and promote the industrialization of H. tuberosus. We conducted a field comparison test on 6 introduced H. tuberosus varieties and 1 local variety, and investigated the growth period, agronomic traits and economic traits of each variety in field. The results show that the comprehensive traits of ‘Langyu No.1’ and ‘Langyu No.2’ are relatively good, with the yield of 57378.68 and 56228.10 kg/hm², respectively, which is 5.11% and 3.00% higher than that of the control. The rest of the varieties show average performance, their yields are lower than that of the control and should be further tested under field condition. ‘Langyu No.1’ and ‘Langyu No.2’ are more suitable for planting and promoting in Yan’an.
