我国长江以北的花椰菜采种,一般是头年夏末秋初播种育苗,冬季移栽到冷床保护越冬,第二年6—7月采种;或2月间温室育苗,4月下旬栽植到露地采种.这种采种方式,需要一定防寒设备,所生产的种子成本高,且数量少.新疆各地栽植花椰莱所用种子主要从内地购进,种子数量、质量得不到保证,生产受到很大影响.1981—1983年,我们利用焉耆地区的有利条件,探索花椰莱当年露地播种采种的可能性,获得了成功,每亩收获种子30—60公斤.现将这一采种技术简介于下.
The cauliflower is planted to the north of the Yangtze River in China. It is generally the first year of summer, the beginning of autumn and the beginning of autumn. Seedlings are planted in winter and transplanted into cold beds to protect winters in the first year. The plants are planted in June-July of the following year; or the nursery in February is planted in open fields in late April. Seed collection. This kind of seed collection methods, you need a certain cold equipment, the seeds produced by the high cost, and a small number of seedlings planted throughout Xinjiang Cocola among the major purchases from the Mainland, the number of seeds, the quality can not be guaranteed, the production is greatly affected In 1981-1983, we exploited the favorable conditions in Yanqi Prefecture to explore the success of the open-field seeding of Caochailai in that year, and succeeded in harvesting 30-60 kg of seed per acre.
