How to manage winter-crop peppers after transplanting? A detailed explanation of the latest technical points

Peppers are the most common vegetable in our lives, and many people simply cannot do without them for all three meals a day. Now, growing overwintering peppers allows them to reach the market around the Spring Festival and bring higher returns. At this point, some farmers are asking how winter-crop peppers should be managed after transplanting. Let's take a look together with the editor below.

1. Temperature management

Winter temperatures are relatively low and cannot meet the needs of normal pepper growth, so before the seedlings recover, do not water, and close the greenhouse appropriately to promote root development. During the day, the temperature should be controlled at 26-30 degrees, and at night it should be kept at 18-20 degrees. After the seedlings recover, the daytime temperature should be controlled at 25 degrees, and at night it should be kept at around 15-18 degrees. When the plants enter the flowering and fruiting stage, the temperature gradually drops. At this time, the straw mats should be uncovered early and covered late, so that the temperature inside the greenhouse reaches an environment suitable for pepper growth.

2. Fertilizer and water management

After the peppers are transplanted, the temperature inside the greenhouse is relatively low, so watering should be reduced. When the soil becomes dry, 1-2 light waterings can be given. Watering should be done in the morning on a sunny day, and after watering, the greenhouse should be closed promptly to raise the ground temperature and promote root development. In the afternoon, it should be ventilated to remove moisture and reduce air humidity, so as to prevent pests and diseases. In deep winter, if water shortage occurs, light watering should be done, and flooding irrigation must not be used. At the end of winter, when the temperature rises, try not to water, so as to avoid excessive vegetative growth of the plants and cause flower and fruit drop. The seedling stage is a key period for pepper fertilizer needs. At this time, some decomposed organic fertilizer should be applied. For greenhouses with severe disease, some bio-organic fertilizer can be applied, which can improve soil structure and reduce the occurrence of diseases.

3. Pruning and fruit thinning

During the pepper growth period, deformed fruits and side branches below the first pepper should be removed in time. This can save nutrients, promote full fruit development, and increase both yield and quality. To prevent the plants from lodging, measures such as inserting supports and hanging vines can be adopted. When the plants grow to 40 cm tall, hang the vines, which can prevent lodging caused by bearing too much fruit.

4. Flowering stage management

Low temperature, high humidity, and weak light in winter are one of the main causes of flower and fruit drop in peppers, so when winter-crop peppers enter the flowering stage, measures such as appropriately increasing ventilation, reducing humidity, increasing light, and raising temperature should be taken to improve the fruit-setting rate, which has a clear effect on increasing yield.
