Comparison of Intercropping and Pure Cropping as Determinants of the Stem and Canopy Foliage of Linseed (Linum Usitatissimum L.) and Pea (Pisum Sativum L.) Cultivars and Their Productivity

ABSTRACT

In a two-factor field experiment, the stem and leaf characteristics and productivity of the ‘Flanders’ and ‘Barbara’ linseed cultivars were compared in four developmental stages in relation to the sowing method. The linseed grown in intercropping with pea, irrespective of the cultivar, was characterized by small leaves in the stem extension stage, but the leaf area significantly increased beginning with the budding phase. Comparison of the cultivars showed that the Barbara cultivar had significantly more leaves on the stems, which significantly affected the final protein yield. The choice of linseed cultivar for oilseed–legume intercropping was of great importance for the final yield. Among the mixtures compared, the one composed of ‘Barbara’ linseed and ‘Phönix’ pea was more productive. Cultivation of ‘Flanders’ linseed resulted in high yield in the pure stand and a high-fat yield. Intercropping of linseed with pea resulted in REI values above 1, which demonstrates the agrobiological suitability of the mixture.

抽象

在双因子大田试验中，比较了不同播种方式下“佛兰德斯”和“芭芭拉”亚麻品种在4个发育阶段的茎叶特性和生产力. 与豌豆间作的亚麻籽，不论品种，在茎膨大期均表现为小叶，但从出芽期开始叶面积显著增加. 品种间比较表明，芭芭拉品种茎上叶数明显增多，对最终蛋白质产量有显著影响. 油豆种间作亚麻籽品种的选择对最终产量具有重要意义. 在比较过的混合物中，由‘芭芭拉’亚麻籽和‘菲尼克斯’豌豆组成的混合物更有效率. “佛兰德斯”亚麻籽的栽培使纯林产量高，脂肪产量高. 亚麻籽与豌豆间作的REI值均在1以上，说明了该混合物的农业生物适宜性.
