Latest Techniques and Methods Tutorial for Fruit Retention in Greenhouse Cucumbers
Greenhouse cucumber cultivation is now very common in our country, and it is mainly carried out in winter. Because winter temperatures are low and the sunshine duration is short, the growth of cucumbers is relatively weak. So if we want to increase yield, when growing greenhouse cucumbers, reasonable fruit retention is very important. So how should we retain fruits when growing them? Today the editor brings you the fruit retention techniques for greenhouse cucumbers. Let's take a look below!
1. Whether to Keep or Remove the Root Cucumber
After the cucumber plant has set the root cucumber, we should pay attention to controlling the timing of whether to keep or remove it. The choice of timing for keeping or removing it has a very large effect on the growth of the cucumber. It should mainly be determined according to the length of the root cucumber. Generally, whether to keep or remove it should be decided when the root cucumber is about 8-9 cm. If the growth of the root cucumber has never been very strong, then it can be picked off when the root cucumber grows to about 7 cm. On the contrary, if the growth of the root cucumber remains strong, then the picking time should appropriately be delayed. By deciding whether to keep or remove the root cucumber based on its length, the growth of the cucumber plant can be adjusted to ensure that the growth of the cucumbers remains consistent.
2. It Is Not Advisable to Keep Too Many Fruits
During the peak fruiting period of cucumbers, many people feel that the growth of the cucumber plant is relatively strong. So they keep every cucumber and dip every cucumber. In fact, if it is grown in winter, then this method of fruit retention is inappropriate. Because winter temperatures are low and natural light is insufficient. The nutrient accumulation in the cucumber plant is not much, and the growth of the plant is not very strong either. If too many fruits are retained, then each cucumber will compete with the others for nutrients. This easily produces deformed cucumbers, and in the later stage it can also easily cause premature aging of the plant and reduce yield. Therefore, in the early stage of fruit setting, keep about 3 cucumbers per plant. In the late stage of fruit setting, the plant growth is weaker, so fewer fruits should be retained appropriately. Usually, keeping about 2 is enough.
3. Reasonable Topdressing
After retaining the fruits, we should also do a good job of topdressing according to the actual condition of the cucumbers. If the cucumbers grow quickly and the fruit strips are straight and glossy, then topdressing may not be needed. On the contrary, if the cucumbers are dull and lack luster, or are curved and deformed, then topdressing should be carried out in time. The fertilizer for topdressing should mainly be Gaojiaxing water-soluble fertilizer, which has high absorption and utilization rates, to promote the fruit strips to return to normal as soon as possible. And it is also necessary to ensure the balance between vegetative growth and reproductive growth of the plant, control the amount of fertilizer applied well, and avoid burning seedlings and soil salinization caused by excessively high concentration.
In winter, the soil temperature is also very low, so the root activity of cucumbers is also very poor. Phenomena such as yellow leaves and yellow heads are prone to appear. Therefore, when fertilizing, in addition to applying an appropriate amount of chemical fertilizer, we should also pay attention to the application of various functional fertilizers. For example, microbial inoculants, chitin, etc. At the same time, spraying and drenching should be combined. For example, when drenching, appropriately spraying a suitable amount of full-nutrient foliar fertilizer on the leaves is more beneficial to the growth of the plant and can also delay the aging rate of cucumber leaves.
The above is a brief introduction to the fruit retention techniques for greenhouse cucumbers. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
