Latest Technical Methods Tutorial for Mid-to-Late Stage Management of Cucumber
Cucumber is a typical cucurbit vegetable, well-liked by many people in our country, very rich in nutrients, and with broad market demand. When growing cucumbers, management work is very important, especially after the mid-to-late stage when cucumbers enter the flowering and fruiting period. So how should cucumbers be managed in the mid-to-late stage? Below, the editor brings you the mid-to-late stage management techniques for cucumber. Let's take a look!
1. Pruning management
If the variety being grown is one that fruits on the main vine, then when pruning we should remove the side branches and tendrils from the plant. Then wrap the plant around the hanging string, encouraging the cucumber to rise in a snake-like manner, and then combine this with flower and fruit thinning work. Remove overly dense female flowers and deformed fruits, etc. For spring-crop cucumbers, during the growing period, the leaves can number more than 60. At this time, pay attention to lowering the vine, and re-tie the vine at the growing tip of the plant, doing this about two times. If it is an autumn-crop cucumber, carry out pinching to promote the growth of returning fruits.
2. Temperature management
When growing cucumbers, we should control the growing temperature according to the growth habits of cucumbers, keeping the temperature range within 15-35 degrees. And we should pay attention to controlling the day-night temperature difference well, and reasonably adjust the temperature according to the growth stage of the cucumber. During the cucumber fruiting period, the temperature should be controlled at around 28 degrees, and the day-night temperature difference should be kept at around 10 degrees. When warming the nutrient solution, the day and night temperatures should both be appropriately lowered by about 3 degrees. If the temperature is too high, then pay attention to doing good ventilation and cooling work to avoid scorching.
3. Removing old leaves
Cucumber leaves are divided into young, functional, and old leaves, etc. The photosynthesis of young leaves is relatively poor, and the chloroplasts have not yet fully developed, so they need functional leaves to provide nutrients. Functional leaves have relatively many chloroplasts and are also the main leaves for photosynthesis, supplying the nutritional needs of the organs of the whole plant. After about two months, functional leaves gradually age and form old leaves. The photosynthetic capacity of old leaves is also relatively poor, and the photosynthetic substances they produce are only enough to maintain their own consumption, and are gradually insufficient. So we should promptly remove old leaves to prevent the functional leaves from bearing too heavy a burden. This can also improve the plant's ventilation and light penetration, and reduce the occurrence of pests and diseases.
4. Fruit preservation measures
If big-bellied cucumbers appear in the mid-to-late stage, then this is mainly caused by poor fertilization. When the temperature rises, if nutrition is insufficient, it leads to plant weakening, and wasp-waisted cucumbers are prone to appear, mainly caused by a lack of nutrition. There are also various undesirable cucumbers such as bitter cucumbers and abortion of cucumbers, so we must do different fruit preservation measures according to different situations. For example, when cucumber abortion occurs, pay attention to spraying glucose, widening the day-night temperature difference, etc. Cucumbers should not be too dense; if too many fruits set, the fruits will compete with each other for nutrients, leading to cucumber abortion.
The above is a brief introduction to the mid-to-late stage management techniques for cucumber. Mid-to-late stage management of cucumber is very important. Timely harvesting provides sufficient nutrients and growing space for new cucumbers, ensuring yield. That is all for today's introduction.
