油菜是我省的主要油料作物。种好油菜不仅是人民生活的需要,而且对促进农业生产发展有着重要作用。近几年耒,我省油菜生产虽有发展,但单产水平低,主要原因是:优良品种推广面积小,肥料不足,密度偏稀,耕作粗放。要提高油菜单产水平,需进一步改进油菜栽培技术。现根据近几年的调查与本所试验,对1979年油菜生产提出如下几点意见,供参考。一、选用早中熟甘兰型油菜品种甘兰型油菜具有适应性广、耐肥、抗倒、抗病力强、油质好、产量高等优点,一般比白菜型油菜品种增产30—50％,甚至成倍增产。南昌县向揩公社农科所、进贤县温家圳公社农料所、乐平县镇桥公社、宜春县东方红公社、商安县东方红公社、波阳县棉花原种场、湖口县胜利大队、信丰县游州大队等单位,油菜年年丰产的一个主要原因,就是坚持了选用甘兰型油菜的早中熟品种。群众说:“白改甘,产量增,早改早增,多改多增”。因此,选用早中熟甘兰型油菜新品
Rape is the main oilseed crop in our province. Planting rapeseed is not only the needs of people’s lives, but also plays an important role in promoting the development of agricultural production. In recent years, although the development of rapeseed production in our province, but the low yield, the main reason is: promotion of small varieties of small size, lack of fertilizer, the density of more dilute, extensive farming. To improve the level of rapeseed production, rapeseed cultivation techniques need to be further improved. Now according to the investigation and the test of our institute in recent years, we put forward the following opinions on the rapeseed production in 1979 for reference. First, the selection of early-maturing Brassica napus varieties Brassica napus has wide adaptability, resistance to fat, anti-down, strong resistance, good oil quality, high yield, generally more than cabbage rapeseed varieties yield 30-50% , Or even doubled production. Nanchang County Agricultural Bureau to the commune, Jinxian Wen Jiaxun commune Jinxian, Leping County town commune, Yichun County Dongfanghong commune, Shangan County Dongfanghong commune, Bo Yang County cotton seed field, Hukou County victory unit, Xinfeng County Tour State Brigade and other units, a major reason for rapeseed yield every year, is to insist on the selection of early blueberry varieties of rapeseed varieties. The masses said: “White change to Gan, output growth, early change increased, change more and more.” Therefore, the selection of early mid-ripe sweet rape new products
