一、玉米是中部优势作物。按照生物全息律,其强遗传优势区在果穗中下部,选用这一部位所结的籽粒作种,比用顶部的籽粒作种增产35.4%。二、高梁是顶部优势作物。果穗上部的籽粒充实饱满,发育好,生活力强,对结实丰产性状具有较强的遗传势,选用全穗三分之一以上部位的籽粒作种,比用中部籽粒作种增产6.4～10.8%.比用全穗混合籽粒作种增产8.7%。
First, corn is the central advantage of crops. According to the bio-holographic law, its strong genetic predominance zone is in the middle and lower part of the ear, and the seeds that are in this part are used as seed, which is 35.4% higher than that of the top seed. Second, sorghum is the top of the crop. The ear of the upper part of the ear full full, good development, strong vitality, strong genetic potential for the strong and yielding traits, selection of more than one-third of the whole area of the seed as seed, than the central grain for seed production 6.4 ~ 10.8% It was increased by 8.7% compared with wholegrain mixed grain.
