利用杂种优势是大幅度提高农作物产量的途径之一。目前我省已初步育成了甘兰油型菜“三系”材料和优势较强的杂交组合,并开始在生产上试种。为了弄清杂交油菜的生育特性和对施肥量的反应,为大面积推广提供依据,特进行了施肥量对杂交油菜生长发育和产量形成影响的研究。 The use of heterosis is one of the ways to significantly increase crop yields. At present, our province has initially bred Klan oil-type dishes “three lines” materials and advantages of strong hybrid combinations, and began to try on production. In order to understand the characteristics of hybrid rapeseed and its response to the amount of fertilizer to provide the basis for the promotion of large areas, especially the amount of fertilizer on the growth and yield of hybrid rape research.
