In the early winter season, greenhouses have also entered a low-temperature and high-humidity environment. Watering and fertilizing in agricultural management has gradually become a headache for vegetable farmers. The weather is changeable. Once a watering problem occurs, it is easy to cause multiple problems. Therefore, here, the reporter reminded the vegetable farmers to pay attention to the following three items when watering.
Pay attention not to water according to the daily habits of many vegetable farmers, but it is very unreasonable to water according to the day. Especially after entering the winter, watering by the day is the main cause of poor root development and the yellowing of plant leaves. .
In winter, when the ground temperature is low, watering by water is usually relatively large. It is easy to cause the ground temperature to be low for a long time, and the roots are stunted, and it is easy to cause the occurrence of cracks, split stems and other symptoms.
Pay attention to maintaining soil moisture balance Soils that are too dry or too wet can easily affect plant growth. Therefore, it is critical to maintain good water balance in the soil.
In winter, watering must be determined according to the soil moisture content, because when the soil moisture content is lower than 40%, it is not conducive to the absorption of nutrients, and when the water content exceeds 80%, it easily leads to the deterioration of soil permeability, and the lack of oxygen in the root system. , causing roots.
Pay attention to the growth of the plants and the environment. According to the growth status of the plants, in particular, observe the blade angle, flexibility, flatness, and flexibility of the vines to avoid over- or under-watering.
In addition, when watering, it depends on the growing environment of the plants, ie the weather and the ground temperature. Winter rainy days do not water, watering is generally selected in sunny days, pay attention to the ground temperature, sunny watering at noon, it is easy to fry, so often selected in the morning, when the ground temperature is maintained at about 15 °C, when the ground temperature and water temperature The smaller temperature difference will have a relatively weaker influence on the root system.
