What happened to the cucumber in the greenhouse?

Now the planting area of cucumber is relatively large in our country, but now cucumber is mainly planted in greenhouse. In the cultivation of cucumbers in the greenhouse, if the management is improper, then there is often the phenomenon of cucumber turning into melons. Cucumber melons will have a great impact on yield and efficiency. So what happened to the cucumber in the greenhouse? Today, the editor will give you a brief introduction. Let's take a look at it.

1. High temperature melons

When planting cucumbers in the greenhouse, if the temperature in the greenhouse is higher than 30 degrees in the day and 16 degrees in the evening, it is very disadvantageous to the growth of cucumbers. It will aggravate the respiration of cucumber, thus hindering the photosynthesis of cucumber. It leads to the phenomenon of melons due to insufficient nutrition of cucumber plants, and the female flowers can not develop normally, which is easy to form deformed melons. Then in the early stage of cucumber melon, the growth rate of stems and leaves is relatively fast. Melon strips are relatively slow, if the temperature is high for several days in a row, then nutrients will be transported to the stems and leaves, resulting in excessive growth of melon seedlings, resulting in a large number of melons.

2. Improper water and fertilizer

Cucumber in photosynthesis, is definitely inseparable from water and fertilizer. Because photosynthesis needs to absorb water and fertilizer through cucumber roots as raw materials, but also with water as the main medium. Therefore, if there is no sufficient water and fertilizer, it will reduce the photosynthetic matter of cucumber, resulting in insufficient nutrition of cucumber. On the contrary, if there is a high temperature and humidity at night and there is a surplus of nitrogen and other fertilizers, it is easy to lead to the overgrowth of cucumbers. This is also a major reason leading to cucumber, so we must pay attention to do a good job of fertilizer and water management.

3. Gas factor

The gas in the greenhouse is also very important for the growth of cucumbers. Cucumbers are also very sensitive to gas changes. If there are too many harmful gases such as carbon monoxide and sulfur dioxide in the greenhouse, it will inhibit the growth of cucumbers. As a result, the melon phenomenon appeared in cucumber, which seriously affected the yield of cucumber. Therefore, we should pay attention to do a good job of ventilation and ventilation, improve the air quality in the greenhouse and remove harmful gases. At the same time, we can also add an appropriate amount of carbon dioxide to the greenhouse, which can effectively reduce the phenomenon of melons, thus improving the yield and quality of cucumbers.

4. Pressure spray melons

It usually takes about a week to harvest cucumbers in greenhouse from flowering to harvest. This time is also the best time for cucumber harvest, if the cucumber plant is not harvested in time after maturity, then it will absorb a lot of assimilation substances. Resulting in insufficient nutrition of female flowers in the upper part of cucumber plants, resulting in melons. Therefore, we should remove the mature melons in time, especially the bottom melons, so as to avoid affecting the growth of the upper melons and reduce the phenomenon of melons. At the same time, timely replenishment of nutrition will also be a key measure to reduce the phenomenon of melons.

The above is a brief introduction to what happened to cucumber in the greenhouse. That's all for today's introduction. This article is for reference only. I hope it can help you all.
