“秦油二号”是世界上第一个大面积应用于生产的三系配套的杂交油菜新品种。1986年秋引入我省。四年来,各地先后进行了多点试验和大面积示范。据不完全统计,1990年全省已有70多个县种植,面积超过40万亩,表现优势明显,适应性广,抗逆力较强,高产低耗。在中等肥水条件下能获得亩产150公斤左右,按高产配套栽培,亩产可超过200公斤,比目前我省推广的常规油菜良种增产20％以上。为了积极稳妥地搞好“秦油二号”的示范,达到增产增收的目的,在把好 “Qin oil two” is the world’s first large area used in the production of three-line hybrid rapeseed new varieties. Introduced to the province in the autumn of 1986. Over the past four years, various localities have carried out more experiments and large-scale demonstrations. According to incomplete statistics, in 1990, the province has planted more than 70 counties with an area of ​​more than 400,000 mu and has obvious advantages in performance, wide adaptability, strong resilience and high yield and low consumption. Under medium fertilizer and water conditions, 150 kg per mu can be obtained. According to the high-yield cultivation, the per-mu yield can exceed 200 kg, which is 20% higher than that of the conventional rapeseed popularized in our province. In order to proactively and steadily do a good job in the demonstration of “Qinyou No.2” and achieve the goal of increasing production and increasing revenue,
