1. Lightly spray the seedling water. After planting the greenhouse tomato, the water requirement for slow seedlings is not large. For this reason, the watering of the seedlings should be lightly watered once every 7 days after planting, and it should be timely cultivated and warmed.
2. Small watering of flowering water. Tomatoes in greenhouses grow stronger in the early stage of flowering. For this reason, it is necessary to pour a small amount of water depending on the degree of soil drought. If the amount of water is too large, it will cause the leaves to grow.
3. Pour the water to promote the fruit. When the first ear of the tomato in the greenhouse grows to a diameter of about 1 cm, it enters the growth period. At this time, it should be poured once to promote the fruit to enlarge, so as to avoid the occurrence of dead fruit.
4. Always pour fruit water. At this time, it is necessary to water frequently to keep the soil moist. Generally, it is necessary to pour water once every 3-5 days to prevent the occurrence of hollow fruit or deformed fruit.
5. Do not pour low temperature water. If the water temperature is too low, the ground temperature will drop sharply, affecting the temperature rise, which will easily cause the roots and roots of the plants. Therefore, it is not advisable to pour the pond water.
6. Do not water on cloudy days. It affects the rise of temperature, and causes the humidity of the air in the shed to increase, causing diseases such as early blight and late blight.
7. Do not water in the evening. Tomatoes should not be watered at night, especially after the results, the humidity in the shed will be too large, causing diseases such as gray mold and disease, and the plants will be long or mad.
8. Not flooding. Flooding of large water not only causes the ground temperature to drop sharply, but also may cause tomato cracking, which may also cause soil compaction, affecting root respiration and plant growth.
