Technique of Cucumber Retention in Greenhouse

Cucumber planting in greenhouse is very common in China, mainly in winter. Because of the low temperature and short light time in winter, the growth of cucumber is relatively weak. So if we want to increase the yield, it is very important to keep melons reasonably when planting cucumbers in the greenhouse. So how do we keep melons when we plant them? Today, the editor brought you the technology of keeping cucumbers in the greenhouse. Let's take a look at it.

1. Go and keep the root melon

After the cucumber plant sits on the root melon, we should pay attention to control the departure and retention time. The choice of departure and retention time has a great influence on the growth of cucumber. Mainly according to the length of the root melon to determine, generally should be in the root melon 8-9 cm to determine whether to stay or not. If the root melon growth has not been very strong, then the root melon can be removed when it grows to about 7cm. On the contrary, if the root melon continues to grow strongly, then try to delay the picking time. Through the length of the root melon to adjust the growth of cucumber plants to ensure that the growth of cucumbers is consistent.

2. It is not advisable to leave more melons.

During the peak period of cucumber fruiting, many people think that the growth of cucumber plants is stronger. Therefore, melons will be kept and dipped in melons. In fact, if melons are planted in winter, then this method of retaining melons is inappropriate. Because of the low temperature in winter and the lack of natural light. There is not much nutrient accumulation in cucumber plants, and the growth of cucumber plants is not very strong. If you leave too many melons, then each melon will compete for nutrition from each other. It is easy to grow abnormal melons, and in the later stage, it is easy to cause premature senescence and reduce the yield. Therefore, about 3 melons are retained per plant in the early stage of cucumber sitting. The plant growth of sitting melon is weak in the later stage, so it is necessary to leave less melon, usually about 2.

3. Reasonable topdressing

After retaining melons, we also have to do a good job of topdressing according to the actual situation of melons. If the melon grows fast and the melon strips are straight and shiny, then there is no need to topdressing. On the contrary, if the melon is dull and deformed, then it is necessary to apply fertilizer in time. The fertilizer of topdressing should mainly absorb Gaojiaxing water soluble fertilizer with high utilization rate, so as to promote melon strips to return to normal as soon as possible. In addition, it is necessary to ensure the balance between plant vegetative growth and reproductive growth, control the amount of fertilizer application, and avoid burning seedlings and soil salinization caused by excessive concentration.

The temperature of the soil in winter is also very low, so the root activity of cucumber is also very poor. It is easy to appear yellow leaves, yellow head and so on. Therefore, when we apply fertilizer, we should not only apply an appropriate amount of chemical fertilizer, but also pay attention to the application of various functional fertilizers. For example, microbial agents, chitin and so on. At the same time, the combination of spraying and flushing application, such as proper foliar spraying of an appropriate amount of total nutrient foliar fertilizer, is more beneficial to the growth of the plant, but also can delay the senescence of cucumber leaves.

The above is a brief introduction of cucumber melon technology in greenhouse. That's all for today's introduction. This article is for reference only. I hope it can help you all.
