The summer is hot and hot, and the weather is muggy, which is the season of large water demand for the growth of vegetables. the water management of vegetables in this period directly affects its yield and quality. in order to achieve high yield and improve income, watering must be reasonable. So what should we pay attention to in watering vegetables in summer? Let's get to know it.

1. Pay attention to the watering time

Many growers often fall into a misunderstanding, the noon sun as strong, the best temperature, when watering can cool down the heat, but this is extremely wrong. High temperature and strong sunshine in summer, the ground temperature itself is high, after a few small light exposure, the ground absorbs a lot of heat, so the ground temperature is higher, while the water temperature is relatively low, which will greatly reduce the ground temperature. as a result, the metabolism of the root system is weakened, the absorption is weak, and the normal yield is greatly reduced. So summer watering is best in the morning, when the sun is relatively strong at 9-10:00, do not water, as the temperature increases, evaporation of water, will take away a lot of heat, conducive to root activity, increase yield.

2. it is not suitable for flood irrigation.

Many growers think that high temperature in summer, watering should be flooded, size line together, this can play a role in reducing the temperature of the ground, in exchange for ensuring that vegetables have enough water, which is conducive to vegetable growth. In fact, it is a wrong idea, but do not realize that flood irrigation will cause stagnant water in the field, affect the respiration of roots, retting roots very easily, lead to root rot, leaf yellowing, and seriously affect yield and quality. in serious cases, the whole plant will wither and die. Especially for some vegetables that are afraid of waterlogging, we must pay attention to that the amount of water should not be too large in summer. In order to avoid the shortage of water in the roots on one side of the ditch, it is best to irrigate alternately between large and small rows.

3. don't get dry and wet.

During the fruiting period of eggplant fruits and melons, the demand for water is uniform, and it is easy to cause fruit cracking if it is dry and wet. This is because the expansion of the fruit is restrained due to the drought and lack of water in the soil. Once the fruit is watered too much or during the rainstorm period, the fruit will expand rapidly, and the water absorption rate of the pulp exceeds the growth rate of the pericarp, resulting in fruit cracking. Therefore, the summer drought should be timely watering, to keep the soil moist, but the amount of water should not be too large, after the rain should be timely drainage, so as not to cause fruit cracking caused by excessive water absorption.

The above is the summer vegetable watering points for attention, hope to help you, want to know more related knowledge, please follow us.
