芥蓝(Brassica alboglabra Bailey)属十字花科芸薹属的一二年生草本植物,是中国特产蔬菜之一,原产我国南方,现主要分布在广东、广西、福建和台湾,北京、上海、南京和杭州等地也开始引种栽培,并传入日本、澳州、欧美各国。以其肥嫩的花薹及嫩叶供食用,质脆嫩,清甜可口,风味别致。为了丰富人们的菜篮子,满足菜农对芥蓝种子的需求,近几年来,我们开始了芥蓝的制种工作,并达到亩产96kg的产籽量。现介绍如下: 一、生物学特性芥蓝发芽期及幼苗期生长适温25～30℃,20℃以下发芽慢,不整齐,35℃以上幼苗生长不良。菜薹形成适温为20～25℃,喜较大的昼夜温差,低于20℃菜薹形成缓慢,
Brassica alboglabra Bailey belongs to Brassica alboglabra Bailey. It is one of the Chinese specialty vegetables originating in southern China. It is mainly distributed in Guangdong, Guangxi, Fujian and Taiwan, Beijing, Shanghai, Nanjing and Hangzhou and other places have also begun to introduce cultivation, and introduced to Japan, Australia, Europe and the United States. Its fat flower stalks and leaves for food, crisp and tender, sweet and delicious, unique flavor. In order to enrich people’s basket of vegetables and meet the needs of growers for kale seeds, in recent years we started the production of kale and reached a yield of 96 kg per mu. Are introduced as follows: First, the biological characteristics of Chinese kale germination and seedling growth suitable temperature 25 ~ 30 ℃, less than 20 ℃ germination slow, irregular, above 35 ℃ poor growth of seedlings. The suitable temperature for the formation of vegetable sprouts is 20-25 ° C, like the larger temperature difference between day and night, the sprouts form less than 20 ° C,
