How to irrigate chili in winter

Pepper is a common seasoning vegetable in our life, which is cultivated all over our country. for other vegetables, pepper has strict requirements for soil water content, and it is a crop that is neither drought-resistant nor waterlogging-resistant. And the temperature is low in winter, how to water it? Let's take a look at the detailed introduction with the editor.

1. It is strictly forbidden to follow the trend blindly.

Most of the cultivation in winter is through the greenhouse, and its indoor space is relative to Mo Feng, and the volatilization and infiltration of soil water content is much slower than that of open field cultivation, so if watering is too frequent, the water can not seep and evaporate. It will cause stagnant water and harm the root system. Therefore, watering chili peppers in winter must be combined with the specific growth of the main stem and seasonal changes, must not blindly follow the trend of watering.

2. No watering in low temperature, cloudy and rainy days

The temperature in winter is already low, when the cold wave comes, the air temperature and ground temperature in the greenhouse will drop rapidly, at this time, if we irrigate again, it will further reduce the ground temperature in the greenhouse, so it is easy to appear diseases and insect pests and retting roots. Therefore, do not water in low temperature and rainy days, if the rainfall is heavy, we also need to do a good job of drainage, in addition, the usual watering in winter should be determined according to the ground temperature, and the water temperature should be controlled close to the ground temperature. in this way, it will not cause a rapid decline in ground temperature and affect the growth and development of the root system.

3. Irrigation time

The outside temperature is generally low in winter, so the morning is the best time to irrigate. Before 10:00 in the morning, it is best to choose well water. It is not recommended or forbidden to use river water, and irrigation at noon and night is not recommended. To prevent a sudden drop in ground temperature and increase the humidity of the greenhouse, make the stem disease increase. In the rainy and snowy weather after irrigation, when the humidity in the greenhouse is high, we can choose to use aerosol to maintain the stem to avoid being harmed by diseases and insect pests.

4. Irrigation method from cloudy to sunny day

The winter in the south is mostly overcast and rainy, and for a long time, the temperature and ground temperature in the greenhouse are extremely low. If the climate suddenly turns fine, the temperature will pick up quickly. However, the temperature of the soil layer rises slowly, and the rhizome is still relatively poor, so if irrigated, it will lead to ground temperature cultivated land, physiological water-deficient plants in the rhizome, and diseases and insect pests.

The above is the introduction of how to water chili peppers in winter. I hope I can help you. If you want to know more about it, please pay attention to us.
