1.抓原种关这是保证种子纯度的基础关,必须严格把握。对原种的来源一定要按原种管理的有关规定,到国家指定的专门生产繁殖单位,科研生产单位调入,杜绝使用来源不清的原种投入生产。将调入的原种还要进行室内复检,鉴定其纯度状况,看大豆脐色、粒色是否一致,粒型是否整齐一致。测定病斑、虫口率指标,最后测定芽率。有条件的单位,可以做室内幼苗鉴定,鉴定其幼苗叶形、茎色,确定原种的纯度,通过复检达到原种标准的可准予使用,不够原种标准的不能使用。
1. Grasp the original seed clearance This is the basis to ensure seed purity, must be strictly controlled. The origin of the original species must be based on the relevant provisions of the original species management, designated to the country’s specialized production and breeding units, scientific research and production units transferred to eliminate the use of unclear sources of raw materials into production. Will be transferred to the original species but also for indoor re-examination, identification of its purity status, see the soybean navel, whether the same color, grain neat and consistent. Determination of lesions, insect mouth rate indicators, the final determination of bud rate. Conditional units, you can do indoor seedling identification, identification of its seedling leaf shape, stem color, to determine the purity of the original species by retesting of the original standard can be allowed to use, not the original standard can not be used.
