眼下,又要开始播种秋白菜了。秋白菜生产,在历史上是风险性比较大的一种蔬菜,主要是受病毒、霜霉和软腐这三大病害的威胁。所以,在秋白菜的品种选择上应特别注意抗病性问题,不能只看近几年没有出现大的问题,而忽视对秋白菜品种的选择。过去在秋白菜的品种选择上,是为了追求产量而不分具体条件,尽量多种些产量高的大型青帮系统品种,不大考虑白菜品质好坏;而近两年来,大部分地区热衷于选用中等棵型、外叶少、包心实、质地较嫩的白帮系统品种,消费者满意,农民又不少收入。但是,我们发现有些地方,在这个问题上从单纯追求产量的一个极端走向了另一个极端,不考虑土肥水等生产条件,单纯迎合市场需求,过多地选用产量低、抗病差又不耐贮藏的白帮系统品种,是不大合适的,偏
Right now, we have to sow autumn cabbage again. Autumn cabbage production, historically a relatively risky vegetable, is mainly threatened by the three major diseases of viruses, downy mildew and soft rot. Therefore, the choice of varieties of autumn cabbage should pay special attention to the disease resistance, can not just see no major problems in recent years, while ignoring the choice of autumn cabbage varieties. In the past the variety of autumn cabbage selection, is to pursue the output regardless of the specific conditions, as much as possible a variety of large-scale production of high-green system, do not consider the quality of cabbage quality; and the past two years, most of the areas keen on the selection Moderate tree type, less outer leaves, heart package, texture and tender white broom system varieties, consumer satisfaction, farmers and a lot of income. However, we find that in some places, we are going to go from one extremist point of pursuing output to the other extremist on this issue. Without regard to the production conditions such as soil, fertilizer and water, we simply cater to the needs of the market. Too much use of low yield, poor resistance and impatience Whitebaked storage system varieties, is not suitable, partial
