It hasn't rained for more than ten days, and vegetables in vegetable fields are seriously affected by drought. Is it better to water it in the morning or at night?

It depends on which season. If it is in summer, it is best to water it at night. If it is spring and autumn, it is better to water it in the morning.

First, it doesn't rain for ten days, and the time to water the vegetable fields in the summer with severe drought.

It is very hot in summer. If it doesn't rain for ten days and it doesn't rain at high temperature for a long time, the vegetable field is seriously dry, which is very unfavorable for vegetable growth and will also affect the yield. In order to alleviate the drought, it is necessary to water the vegetable fields artificially. Pay attention to choose to water the vegetable fields in summer, that is, after 5 pm, because the temperature is high and the air is dry in summer. If you water in the morning, the temperature will rise rapidly as soon as the sun comes out. If you water less, the vegetables may dry before absorbing water. When the temperature is the highest at noon, if there is more water, there will be water in the ground, and the vegetables may be steamed to death as soon as the sun shines. On the contrary, watering at night will not only make no difference. So remember, even if it doesn't rain for ten days in summer, don't water the vegetable fields at noon to avoid harming the vegetables.

Second, it didn't rain for ten days, and the vegetable fields were seriously dry. Time for watering vegetable fields in spring and autumn.

The temperature difference between day and night in spring and autumn is not too big, and the air humidity is low, so transpiration will not be greatly affected after watering. Although there is little difference between watering in the morning and watering at night, after watering in the morning in spring and autumn, waiting for the sun to come out will increase the ground temperature, which is conducive to the growth of vegetables and accelerate the growth of vegetables. Be careful not to water the vegetable fields at noon in spring and autumn, because the temperature is high at noon, watering will cause the leaves to turn over and affect photosynthesis. At noon, when the ground temperature is high and the water temperature is low, watering will damage the root system of vegetables and may cause vegetable death.

Third, vegetables in vegetable fields are seriously affected by drought and watering skills.

Different vegetables have different needs for water, so they should be watered according to the amount of water needed. Cold-resistant vegetables need less water to produce high yield. At the seedling stage of vegetables, even if they suffer from severe drought, they should be watered with small water, and only after transplanting can they be watered with large water. Remember not to use wet and dry. Rational fertilization when watering.
