The latest course on the techniques and methods of keeping cucumbers in greenhouse

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

1, root melon to stay

After the cucumber plant has settled down, we should pay attention to controlling the time of going and staying. The choice of time to leave and stay 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 or so to determine whether to stay. If the root melon has not grown very strong, then it can be removed when the root melon grows to about 7cm. On the contrary, if root melons continue to grow strongly, then try to delay picking time. The growth of cucumber plants can be adjusted by removing and retaining the length of root melons, so as to ensure the consistent growth of cucumber.

2. It is not advisable to leave more melons

When cucumber is in full bloom, many people feel that cucumber plants grow stronger. Therefore, if there are melons, they will be kept and dipped. In fact, if they are planted in winter, then this method of keeping melons is inappropriate. Because winter temperature is low, natural light is insufficient. Cucumber plant nutrition accumulation is not much, plant growth is not very strong. If you leave too many melons, then each melon will compete with each other for nutrients. It is easy to grow deformed melons, and it is easy to cause premature aging of plants in the later stage, reducing yield. Therefore, in the early stage of cucumber sitting, each plant retains about 3 melons. The late plant growth is weak, so it is necessary to keep less melon properly, usually keep about 2 branches.

3. Reasonable topdressing

After leaving melons, we have to do topdressing work according to the actual situation of melons. If the melon grows fast and the melon strips are straight and bright, then topdressing is not necessary. On the contrary, if the melon is dull and dull, curved melon is deformed, then it is necessary to apply fertilizer in time. The topdressing fertilizer should be based on Gao Jiaxing water-soluble fertilizer with high absorption and utilization rate, so as to promote the melon strip to return to normal as soon as possible. And also to ensure the balance between plant nutrition growth and reproductive growth, control the amount of fertilizer, avoid excessive concentration caused by seedling burning, soil salinization and so on.

Winter soil temperature is also very low, so cucumber root vigor is also very poor. It is easy to appear yellow leaves and yellow heads. Therefore, when applying fertilizer, we should pay attention to the application of various functional fertilizers in addition to applying appropriate amounts of chemical fertilizers. For example, microbial agents, chitin, etc. At the same time, it is necessary to combine spraying and flushing, for example, proper foliar spraying of appropriate amount of total nutrient foliar fertilizer during flushing, which is more beneficial to the growth of plants and can also delay the aging speed of cucumber leaves.

The above is a simple introduction to the greenhouse cucumber technology. Today's introduction is here, this article is for reference only, I hope to help everyone oh!
