近年全省油菜播种面积在450～500万亩,平均亩产菜籽75～80斤,总产量310万担左右。今年全省油莱获得总产超历史的好收成,并诵现出彭泽、永新等县平均亩产超150斤的高产典型。综合各地经验,要使油菜持续高产稳产,必须抓好以下几项技术措施: 一、调换品种是关键 品种的优劣,是高产的关键。甘蓝型油菜具有耐肥、分枝多、粒大、荚果多、增产潜力大、品质好等特点,一般比白菜型油菜增产二、三成,甚至更多。因此,推广甘蓝型油菜是提高单产的重要措施。“821”是中国油料所培育成的冬春型油菜品种,属中迟熟,适宜我省两熟制地区种植。西南302、黔油九号、万油17等中熟品种,适宜三熟制地区种植。 二、壮苗移栽奠基础 壮苗是油菜
In recent years, the province’s rapeseed sown area of 450 to 500 acres, an average of 75 to 80 kg per mu of seed, the total output of about 3.1 million. This year, the province’s oil rape achieved a good harvest of total super-history and recited the high-yield typical of over 150 jin per mu in Pengze and Yongxin counties. Comprehensive experience, in order to make rapeseed high and stable yield, must grasp the following technical measures: First, the exchange of varieties is the pros and cons of the key varieties, is the key to high yield. Brassica napus has the characteristics of resistance to fertilizer, many branches, large grains, large pods, large potential for yield increase and good quality, generally yielding 20-30% or more than that of cabbage type rape. Therefore, the promotion of Brassica napus is an important measure to improve yield. “821” is a winter-spring rape cultivar cultivated by Chinese oilseed. It belongs to mid-late mature and is suitable for planting in the two-cropping system of our province. Southwest 302, Guizhou oil on the 9th, 17 million oil, medium maturing varieties, suitable for planting three areas. Second, strong seedling transplanting laid the foundation Strong seedling is rape
