Principles and precautions for watering vegetables in summer
The temperature in summer is always so hot, and many vegetables need to be replenished with certain water in time. However, there are many novice growers who see their own vegetables and are madly watered. This is actually ineffective. Summer vegetable watering also has its principles and methods.
First, pay attention to watering time
Many novice farmers have such a misunderstanding, when the sun is the strongest and when it is best to water. In fact, this time, the surface temperature is extremely high, the water temperature is low, and a large amount of watering will easily lead to weakening of vegetable root metabolism. This will result in a reduction in production. Therefore, it is best to water in the summer in the morning. Do not pour more than nine or ten.
Second, it is not suitable for flooding
Although the temperature is high in summer, the water is easy to evaporate, but it should not be flooded with large water. Flooding of large water is easy to cause water accumulation in the field, affecting the respiration of the roots, which is prone to rooting, causing roots to rot, yellowing of leaves, seriously affecting yield and quality, and when the soil is severe, the whole plant will wither and die. Especially for some vegetables that are afraid of cockroaches, in the summer, we must pay attention to the amount of watering should not be too large, in order to avoid the lack of water on the root side of the large ditch, it is best to alternate the size of the line.
Third, don't let dry and wet
During the fruiting period of solanaceous fruits and melons, the demand for water is uniform. If it is dry and wet, it is easy to cause cracking. This is because soil drought and water shortage cause fruit swelling to be inhibited. Once the water is too much or during heavy rain, the fruit will be fast. When it is swollen, the moisture absorption speed of the pulp exceeds the growth speed of the peel, causing cracking. Therefore, in the summer drought, water should be watered in time to keep the soil moist, but the amount of water should not be too large. It should be drained in time after the rain to avoid excessive water absorption and cracking.
The above is the principle of watering vegetables in summer. Let's see if it helps. If you have other ways to share, you can leave a message.
