Management techniques in the Middle and late stage of Cucumber

Cucumber is a typical melon vegetable, which is welcomed by many people in our country. It is also very rich in nutrients and has a broad market demand. When cucumber is planted, the management is very important, especially after the cucumber enters the flowering and fruiting stage in the middle and later stage. So how to manage it in the middle and later stage of cucumber? The following editor brings you the management technology of cucumber in the middle and later period, let's take a look at it!

1. Pruning management

If the variety planted is the main vine melon, then we should remove the side branches and tendrils from the plant when pruning. Then the plant was wound around the rope to promote the serpentine rise of cucumber, and then combined with the work of thinning flowers and fruits. Remove the overdense female flowers and malformed fruits. For cucumbers in spring stubble, there are more than 60 leaves during the growing period. At this time to pay attention to the fall of the vine, the plant bibcock re-binding vine, about twice. If it is autumn cucumber, carry on the heart-picking work to promote the growth of melon.

2. Temperature management

When we plant cucumbers, we should control the planting temperature according to the growth habits of cucumbers, keeping the temperature range within 15-35 degrees. And we should pay attention to control the temperature difference between day and night, and adjust the temperature reasonably according to the growth stage of cucumber. During the cucumber fruiting period, the temperature should be controlled at about 28 degrees, and the temperature difference between day and night should be kept at about 10 degrees. When the temperature of the nutrient liquid, the temperature of day and night should be appropriately reduced by about 3 degrees. If the temperature is too high, then we should pay attention to ventilation and cooling work to avoid burns.

3. Pick old leaves

The leaves of cucumber are divided into juvenile, functional and aging. The photosynthesis of young leaves is relatively poor, and chloroplasts are not fully developed, so nutrients need to be provided by functional leaves. There are many chloroplasts in functional leaves, and they are also the main photosynthetic leaves, which supply the nutritional needs of organs of the whole plant. In about two months, the functional leaves gradually aging to form old leaves. The photosynthetic capacity of aged leaves is also relatively poor, the photosynthetic substances produced can only maintain their own consumption, and gradually insufficient. Therefore, we should remove the aged leaves in time to prevent the burden of functional leaves from being too heavy. It can also improve the permeability of plants and reduce the occurrence of diseases and insect pests.

4. Fruit protection measures

If there is a big belly melon in the middle and later stage, it is mainly due to poor fertilization. When the temperature rises, the lack of nutrition will lead to plant weakness and prone to bee waist melon, which is mainly caused by lack of nutrition. Among them, there are bitter melon, melon and other bad melons, so we must do different fruit protection measures according to different situations. For example, when melons appear, we should pay attention to spraying glucose and expanding the temperature difference between day and night. Melons should not be too dense, if there are too many melons, melons will snatch nutrition from each other, resulting in melons.

The above is a brief introduction to the management technology of cucumber in the middle and later stage. The management of cucumber in the middle and later stage is very important, it should be harvested in time to provide sufficient nutrition and growth space for new melons and ensure yield. That's all for today's introduction. This article is for reference only. I hope it can help you all.
