为解决承德坝上地区亚麻品种种植结构单一、产量稳定性较差等问题,采用随机区组试验设计,以承德坝上地区主栽品种坝亚7号为对照,对自张家口市农业科学院引进的5个油用亚麻品种(117、391、1075、白胡麻和陇亚10号)进行了生育期、经济性状、产量、抗病性等多项指标的比较,并对参试品种进行了综合评价。结果表明:117、391、1075、白胡麻和陇亚10号均适宜在承德坝上地区种植。其中,117生育期最长,枯萎病发病率最低;株高最高,茎秆坚韧直立,田间长势整齐,工艺长度最长并且整齐度好,适合机械化操作;分枝数、单株果数、单株生产力和产量均为最高,且没有无效果,综合性状表现最好,最适宜在承德坝上地区种植。1075产量仅次于117,但高于坝亚7号;株高和工艺长适合机械化操作要求;枯萎病发病率低于坝亚7号,综合性状表现较好,可以作为选用品种。
In order to solve the problems such as single plantation structure and poor yield stability of flax varieties in Chengdeba area, a randomized block design was adopted to study the effect of introduction of the major cultivars of BaYa 7 in Shangdeba on the area from Zhangjiakou Academy of Agricultural Sciences Five oil varieties (117, 391, 1075, white flax and Longya 10) were used to compare the growth period, economic traits, yield, disease resistance and other indicators, and the comprehensive evaluation of the tested varieties . The results showed that 117, 391, 1075, white flax and Longya 10 were all suitable for planting in Chengdeba area. Among them, 117 had the longest growing period and the lowest incidence of wilt disease; the highest plant height, the stems tenacious and upright, the field grew neatly, the longest process length and good uniformity, suitable for mechanized operation; number of branches, number of fruit per plant, Plant productivity and yield are the highest, and no no effect, the best performance of the integrated traits, the most suitable planting in Chengde area. The yield of 1075 was second only to 117, but higher than that of No.7 in Ba Ya. The plant height and process length were suitable for the mechanized operation. The incidence of Fusarium wilt was lower than that of No.7 in Ba-Ya. The comprehensive traits performed well and could be used as the selection varieties.
