The cucumber falls to see the sky
In the production, many vegetable farmers do not pay attention to see the sky, so that the cucumber infected with disease after falling. So, what kind of weather should be carried out on the cucumber?
First, cloudy (snow) days are not suitable for falling vines. Because of this kind of weather, the humidity is relatively high, and it is easy to cause diseases. In addition, when cucumbers fall, they often pick and take leaf beard, and the wounds are more likely to be infected by germs. Therefore, do not use cucumbers on cloudy (snow) days.
Second, the cucumbers spread easily in the afternoon. Even if the weather is no better, it is not suitable to fall in the morning, because the humidity in the shed is generally very large, and with the increase of humidity and the increase of ventilation in the shed, the humidity in the shed is very small by the afternoon. Therefore, cucumbers are best left in the afternoon.
Be aware that cucumbers cannot be watered before and after falling. If the cucumbers are watered within 3 days before and after the vines fall, the humidity in the shed will inevitably increase and cause diseases easily. In addition, cucumbers should be promptly sprayed and prevented after falling. In view of the vulnerability of cucumbers to vines, especially in the case of bacterial diseases, it is advisable for growers to use chlorothalonil and other broad-spectrum fungicides mixed with streptomycin or copper preparations to spray the whole shed in time. Prevent the occurrence of diseases.
