不同生态类型荞麦品种的适合性评价

Suitability Evaluation on Buckwheat Varieties of Different Ecological Types

为了促进通辽地区荞麦产业发展,对14个不同生态地区的42个甜、苦荞品种进行3a试验研究,调查其生育期、农艺性状及产量。结果表明:在通辽地区种植的甜、苦荞品种生育期应控制在100d以内,才能保证正常成熟,参试甜荞品种蒙0530、赤甜荞1号和通荞1号与对照(CK)产量接近。苦荞品种中,增产率最高的为苦荞1307-893,产量为3 278.10kg·hm-2,平均增产1 543.5kg·hm-2,其次为黔苦5号、黔苦6号、六苦04号分别比对照增产1 063.35、689.40、295.65kg·hm-2,与对照产量接近的有云荞2号(1 878.60kg·hm-2)、晋苦荞2号(1 814.25kg·hm-2)、晋苦荞6号(1 752.60kg·hm-2)、川苦荞3号(1 664.55kg·hm-2)、酉苦1号(1 579.65kg·hm-2),这些甜、苦荞品种高产、稳产、综合农艺性状较好,均适合在通辽地区种植。

In order to promote the development of buckwheat in Tongliao area ,the grow th period ,agricultural characters and yield of 42 sweet and 3 bitter buckwheat varieties from different ecological areas were investiga‐ted .The results showed that to guarantee fully mature ,the culture period of buckwheat should less than 100 days .The yields of tested sweet buckwheat cultivar Meng 0530 ,Citianqiao 1 and Tongqiao 1 closed to yield of control （CK） .For the tested bitter buckwheat varieties ,the highest yield was obtained from Kuqiao 1307‐893 , was 3 278 .10 kg· hm‐2 ,compared with CK the average yield increased was 1 543 .5 kg-hm‐2 .Followed by Qianku 5 ,Qianku 6 ,Liuku 04 respectively ,yield increased 1 063 .35 ,689 .40 ,2 295 .65 kg-hm‐2 than control . Yield of cultivars Yunqiao 2 ,Jinkuqiao 2 ,Jinkuqiao 6 ,Chuankuqiao 3 and Youku 1 was closed to the control which was 1 878 .60 ,1 814 .25 ,1 752 .60 ,1 664 .55 and 1 579 .65 kg-hm‐2 respectively .These sweet and bitter buckwheat varieties got high and stable yield ,good comprehensive agronomic characters that suitable for plant‐ing in Tongliao area .
