The summer temperature is high, and the water in the plants and soil evaporates quickly, requiring timely watering. Watering is a very common management measure in shed management. Although it seems simple, it is reasonable or not, and has a direct impact on the growth of vegetable raisins. So, what is the way to do this?
Road one: diligent pouring, interlacing
That is to take the planting line and the operation line, and the method of pouring small water alternately, so as to ensure the positive growth of the vegetables, and keep the humidity of the shed to avoid the occurrence of viral diseases and bacterial diseases. The number of watering should be flexibly grasped according to the growth of the vegetables, the dry and wet conditions of the soil, and the weather changes. For example, the day before the continuous abnormally high temperature weather can be appropriately poured into the water for a response.
Road 2: Spraying water
Spray the water on the plant at around 10 am on a sunny day (focus on spraying the upper part of the plant) to prevent "drought". This not only replenishes the leaves, but also reduces the temperature of the shed. Especially for those plants that have entered the late growth stage and whose root absorption capacity is weakened, spraying water has a good effect on alleviating physiological problems such as curling leaves and yellow leaves.
Road 3: Watering time is well arranged
The watering time in summer should be carried out in the morning or evening, which can achieve the cooling effect without causing damage to the vegetable roots. Especially in the evening watering can effectively reduce the night temperature, increase the temperature difference between day and night, reduce the nighttime respiratory consumption of plants, and help the accumulation of nutrients. Remember not to water at noon, to avoid the phenomenon of “fried†roots in the roots of vegetables after cold water stimulation, thus affecting the normal growth of vegetables.
Road 4: Avoid watering after water control
Some vegetable farmers worry about excessive water control for a long time because of plant growth and other reasons. At this time, watering should pay attention to first pouring a small amount of water, so that after 3-5 days of adaptation, the water should be properly poured once, step by step. Conducted. After the long drought, it is not correct to let it "drink" once, which is very easy to damage the roots, causing weak roots, causing early sorrow, and also providing favorable conditions for the occurrence of various root diseases.
