Matters needing attention in watering chili in winter

Pepper is a common seasoning vegetable in our life, which is cultivated all over the country. compared with other vegetables, it has strict requirements for water, and it is a crop that is neither drought-tolerant nor waterlogging-tolerant. So how to water it in greenhouse in winter? Let's take a look at the notes with the editor.

1. it is forbidden to water blindly

When growing chili peppers in winter, the temperature is low, so the greenhouse is mostly used, the space in the greenhouse is relatively closed, and the evaporation and infiltration of soil water are slower than those cultivated in the open field. Therefore, if too much watering, then too much soil moisture will affect the coordination of fertilizer, water, gas and heat in the soil. Therefore, the watering of pepper in winter must be determined according to the actual plant growth and climate, so that the watering is reasonable.

2. Avoid watering in the afternoon

Under the condition that the indoor and outdoor air temperature is relatively low, it is better to water pepper before 10:00 in the morning, and it is appropriate to control the water temperature at about 20 degrees. Watering in the afternoon or evening, the ground temperature can not be increased, and the humidity in the greenhouse is high, so it is easy to be infected with diseases and insect pests. And the day before watering every day, protective pesticides should be sprayed in time, if the next day of watering rain and snow weather, can ignite aerosol for protection.

3. Avoid eye watering with long yin

There are more cloudy days in winter, and the air temperature and low temperature in the greenhouse are relatively low. if the air temperature rises faster after it suddenly clears up, but the ground temperature rises two hours behind the air temperature, the root activity is still weak. If the soil temperature is too low after pouring water for a long time, the root water absorption is affected, and the pepper is prone to physiological dehydration.

4. No watering in low temperature and rainy days

Rain Water watering in winter in the southern region, when the air temperature and ground temperature drop relatively fast, if watering will further reduce the air temperature and ground temperature, but also cause stagnant water retting roots and induce diseases and insect pests, it will have a great impact on the growth and development of hot pepper, light will reduce yield, heavy will not harvest.
