| 摘 要： | 为探讨张家口坝上地区覆膜栽培条件下油用亚麻适宜的种植密度,采用2因素（亚麻品种、种植密度）3水平（品种为坝选三号、陇亚杂1号和陇亚10号,行距为24、20和16 cm）随机区组试验设计,全膜穴播种植（8粒/穴,穴距30 cm）,研究了不同种植密度对油用亚麻生育期、主要经济性状、倒伏率和产量的影响。结果表明：同一品种,除陇亚杂1号行距24 cm与16 cm处理的株高、坝选三号行距24 cm与16 cm处理的千粒重差异较大外,不同密度处理的其他主要经济性状以及生育期和产量差异均不显著,其中,坝选三号、陇亚杂1号和陇亚10号分别在种植行距为20 cm、24 cm和16 cm时产量最高,分别达到了2 146.65 kg/hm^2、1 953.30 kg/hm^2和1 650.00 kg/hm^2;但倒伏率均以行距24 cm处理最高,行距20 cm处理倒伏率均较低。综合分析密度对油用亚麻产量、主要经济性状和倒伏率的影响,认为坝上地区覆膜条件下种植油用亚麻时以行距20 cm为宜。

| Abstract: | In order to discuss the suitable planting density for oil flax in Bashang areas of Zhangjiakou City under the condition of film mulching,using the randomized block design of two factors（ flax variety,planting density）and three levels（ three varieties were Baxuan No.3,Longyaza No.1 and Longya No.10,row spacing were 24 cm,20 cm and 16 cm）, the film mulching and bunch seeding cultivation（ eight seeds / hole, hole spacing was30 cm）,the effects of different planting densities on oil flax growth period,the main economic traits,lodging rates and yield were studied.The results showed that the same variety,except that the height difference of Longyaza No.1 between spacing 24 cm and 16 cm,the 1 000-grain weight difference of Baxuan No.3 between 24 cm and16 cm were significant,the differences of the other major economic traits,growth period and yield in different planting densities were not significant.The yield reached a maximum value for Baxuan No.3,Longyaza No.1 and Longya No.10 under planting spacing 20 cm,24 cm and 16 cm respectively which reached 2 146.65 kg / hm^2,1 953.30 kg / hm^2 and 1 650.00 kg / hm^2.The lodging rate of three varieties get the maximum value under spacing24 cm and lodging rate was relatively low under spacing 20 cm.The comprehensive consideration for the effects of the planting density on oil flax production,the main economic traits and lodging rates,spacing 20 cm for the oil flax planting is the most appropriate in Bashang area under the condition of film mulching. |
