摘要
黑农 4 4属于高脂肪、高产品种 ,其基础与亲本的遗传有关 ,在后代选择上主要是按着母本哈85 - 6 437(黑农 37)生态类型选择。不同密度穴播比条播增产 ,在 15~ 2 5万株 /hm2 时穴播较条播增产 0 .9%~ 13.1% ,同时脂肪含量提高 ;黑农 4 4主要栽培要点是 :密度 2 0~ 2 5万株 /hm2 ,采用穴播 ,种肥施磷酸二铵 15 0~ 187.5kg/hm2 ,实行通透管理 ,防治病虫草害。
Soybean cultivar-Heinong44 is belong to be a high oil content and high yield variety, the causes relate with genetic base of its parents. The select of cross generations was according to female parent(Ha85-6437)'s ecological type. The yield and oil content in bunch planting are higher that in drilling in planting density of between 0.15 million plants/ha and 0.25 million plants/ha. The paper also point out main cultivation keys of Heinong44.
