由于仙客来不喜高温,所以如何在夏季高温季节预防和控制病虫害,便成为目前仙客来生产中最重要的问题。一、品种选择目前国内仙客来品种非常多,仅 F_1代品种就有法国、美国、荷兰等国的多个种源,还有我们国内一些传统的常规品种。在这些品种中,F_1代品种因为经过了杂交选育,所以抗热性能是最好的,基本不存在夏季休眠的情况。所以在确定品种时应尽量选择这些耐热品种。二、环境控制1、温度这是仙客来夏季生产中最受关注的一个环境因素。仙客来的生长适温为18～24℃,在这
As cyclamen do not like high temperatures, how to prevent and control pests in the hot summer season has become the most important issue in the production of cyclamen. First, the choice of varieties At present, China Cyclamen varieties are very large, only the F_1 varieties there are multiple sources in France, the United States, the Netherlands and other countries, as well as some of our traditional conventional varieties. Among these cultivars, F_1 was the best tolerant to heat because it had been cross-bred, with little or no summer dormancy. Therefore, when determining the variety should try to choose these heat-resistant varieties. Second, the environmental control 1, the temperature Cyclamen summer production is the most concerned about an environmental factor. Cyclamen growth temperature is 18 ~ 24 ℃, in this
