The temperature has suddenly dropped recently, and it seems that winter is really coming. Some cucumber growers have prepared greenhouses and made some insulation measures, but even cucumbers in the greenhouse may suddenly languish, which makes the growers feel confused. What are the reasons for this? How can we prevent the cucumbers in the greenhouse suddenly wilting and drowning in the winter?

First, let's first analyze the reasons for the sudden atrophy of cucumbers in winter greenhouses:

1. In the case of a long time of rainy weather, the indoor ground temperature will be relatively low. If the vegetable seedlings are weak, the greenhouse cucumber seedlings with poor heat preservation will easily cause freezing damage.

2. When the majority of vegetable farmers plant cucumber seedlings, the quick-acting chemical fertilizer in the base fertilizer is applied too much, and the concentration of chemical fertilizer in the soil is high, which damages the root tip and reduces the ability of the root to absorb water and inorganic salts.

3. When the weather turns fine, the grasshopper is suddenly uncovered, which will cause the temperature to rise rapidly, and the transpiration of cucumber leaves will increase, causing the physiological loss of water and wilting.

The following measures are taken to prevent cucumber wilting and sudden death in winter greenhouses:

1. Strengthen seedling management and cultivate strong seedlings in the early stage of cucumber growth.

2, usually pay more attention to the changes in the weather, and then strengthen the greenhouse warmth and warming work when the winter cold current strikes, but also pay attention to not pouring too much water.

3. Apply more decomposed organic fertilizer and carry out top dressing.

4. When the weather is fine, the shed should be uncovered, while the side cover is exposed, and the warm water of about 20 °C is sprayed on the foliage, and the old leaves are removed in time to reduce the transpiration. After the vegetable seedlings resume normal growth, all the drafts can be drafted during the day. Even if it is cloudy, the drafts should be drafted as much as possible, so that the vegetable seedlings can see the scattered light. However, it is necessary to cover the two layers of protective film at night to do the insulation work. The seedlings were frozen for the second time.

The measures to prevent wilting and sudden death in winter greenhouse cucumbers are probably the above points. While the cucumber growers are doing basic greenhouse insulation measures, they should pay more attention to the changes of cucumber seedlings in order to prevent sudden changes in cucumbers.
