宁油七号是苏南地区正在推广中的一个甘兰型早中熟油菜新品种,在有些单位,已经成为当家品种。随着苏南地区“油—稻—稻”三熟制的发展,油莱一般要在小雪后移栽,比以往推迟10～15天。为了在晚茬条件下夺取油菜高产,两年来,我们以越溪公社农科站为基地,与农科站同志协作进行试验观察,结合地区生产考察,对宁油七号在晚茬栽培条件下的生长、发育与产量构成,以及夺取高产的途径,进行了探索。现将初步结果分述于下:
NingYou No.7 is a new type of Brassica napus which is being popularized in southern Jiangsu. In some units, it has become the dominant species. With the development of the three oil systems of “oil, rice and rice” in southern Jiangsu, oil lakes generally have to be transplanted in the light snow, which is delayed 10 to 15 days than in the past. In order to seize rape under late crop conditions of high yield, two years, we Yuexi commune agricultural station as a base, in cooperation with the Agricultural Station comrades experimental observation, combined with regional production inspection, Ningyou VII in late cropping conditions Growth, development and yield composition, as well as the means to seize high yield, were explored. Now the preliminary results are described in the following:
