黄瓜是银川菜区栽培的主要蔬菜之一,具有生育期短、适宜套种白菜、多茬栽培(进行露地、保护地、温室、大棚栽培可达到周年生产)等优点。但近年来,银川地区黄瓜霜霉病连续暴发流行,一般每亩只收1000～2000斤,有的甚至无所收成,对黄瓜生产造成了严重的威胁。为了研究霜霉病暴发流行的原因,我们进行了气候、品种等多方面的调查和研究,现总结如下。
Cucumber is one of the main vegetables cultivated in the Yinchuan vegetable area. It has the advantages of short growth period, suitable for intercropping cabbage and multiple cropping (open field, protected area, greenhouse, greenhouse cultivation can reach annual production). However, in recent years, the outbreak of cucumber downy mildew in Yinchuan has been on the rise. Generally, it only receives 1000-2000 jin per acre, and some even has no harvest, which poses a serious threat to cucumber production. In order to study the causes of the outbreak of downy mildew, we carried out various investigations and studies on climate and variety, and are summarized as follows.
