作物的生物学特性、生长发育规律及其对环境的适应性。是制订作物栽培技术措施的理论基础。低芥酸油菜与一般高芥酸油菜有它共性的一面,也有它特殊的一面,且随着低芥品系不同又有所差别。本试验通过对在本省表现较好低芥品系中油低芥3号(81008)、81001、黔油低芥1号(82—11)与高芥油菜湘油2号、黔油9号进行三年系统对比观察研究,从中了解 Biological characteristics of crops, growth and development of the law and its adaptability to the environment. It is the theoretical basis for formulating crop cultivation techniques and measures. Low-erucic acid rape and common high erucic acid rape have its common side, but also has its special side, and with the low-mustard strains vary. In this experiment, the best performance in the province of low-mustard lines of low oil on the 3rd (81008), 81001, Qianyou low on the 1st (82-11) and high mustard Xiangyou 2, Guizhou oil 9 for three years System contrast observation study, from which to understand
