我国北方地区种植秋菜花面积很大,品种也多,收获期长。8月中旬-9月中旬,河北省张家口坝上地区0.53万hm2菜花收获,9月底-10月底,河北省、北京地区露地菜花上市,11月中旬以前河南、江苏省菜花供应量也非常大。这段时间菜花供大于求,市场销售价格低,农民收入有限。利用北京市数量较大的日光温室种植菜花,12月中旬-12月下旬之前上市,不仅栽培管理简单,经济效益也可观。同时还照顾到下茬蔬菜栽培。本文重点介绍日光温室菜花秋延后栽培技术,为生产者提供借鉴和参考。
The cultivation of autumn cauliflower in the northern part of our country is very large in area, with many varieties and long harvesting period. From mid-August to mid-September, 05300 hm2 cauliflower was harvested in the dam area of Zhangjiakou, Hebei Province.
