在紫花苜蓿田地中,往往有许多草木樨混生其中,给苜蓿生产带来不少损失,使苜蓿地生产的种子纯度无法保证,苜蓿的鲜干草也会降低品质。所以,在播种前应对苜蓿种子进行检查。两种种子的主要区别是:紫花苜蓿种子为肾形或宽椭圆形,两侧扁、不平、有角棱、种子稍弯曲或扭曲,长2.0—3.0毫米,宽1.0—1.8毫米,厚0.1—1.1毫米。表面黄色到浅褐色,有光泽。种脐靠近种子长的中央或稍偏下,圆形,黄白色或具一白色环。干粒
In the field of alfalfa, there are often a lot of vegetation mixed with them, which brings many losses to the production of alfalfa so that the purity of the seeds produced in the alfalfa can not be guaranteed and the fresh hay of the alfalfa will also reduce the quality. Therefore, alfalfa seeds should be examined before sowing. The main difference between the two seeds is that the alfalfa seeds are kidney-shaped or broadly oval with flattened sides, uneven edges and angular ribs with slightly curved or twisted seeds, 2.0-3.0 mm in length, 1.0-1.8 mm wide and 0.1-1.1 in thickness Mm. Surface yellow to light brown, shiny. Umbilicus near the seed long central or slightly lower, round, yellow-white or with a white ring. Dry grain
