To say that the vegetable growers care about greenhouse vegetables, it is known to be cold, caring, and prepared, for fear that it suffers from "grievance." However, in the winter, vegetables are often harmed by bad weather. In response, vegetable farmers have spent a lot of thought and come up with many effective countermeasures. This is not the case. Zhao Laiyu, a vegetable farmer in Zhaojiatoutou Village, Qigou Township, Changle County, has learned the magical effect of warm water. Below, let's take a look at how Zhaolaiyu made warm water available.
First, spray water in advance to prevent "flash shed."
As we all know, in the event of a sudden turn of dark weather, the use of “exposing flowers and spraying warm water†is very effective in preventing “flashing shedsâ€. However, Zhao Laiyu believes that this move is also effective. Therefore, he will advance this trick, even when it is cloudy and sunny, he will spray warm water before pulling the grass and then “expose the flowers.†In this way, basically the vegetables will not show wilting symptoms after pulling open the grasshopper, which can effectively avoid the occurrence of “flash shedsâ€.
Zhao Laiyu said that the water temperature should be around 30°C, which should not be too high, because the temperature of the surface of the vegetable leaves in the winter shed is low. If the water suddenly encounters high temperature, it is easy to cause injury. Usually half an hour after the warm water is sprayed, the grasshoppers are pulled up, and the vegetables rarely show wilting.
Zhao Laiyu also told reporters that the amount of warm water required to spray the entire shed is not too large. Generally, a water film can be formed on the leaves, and only 3-4 sprayers can be used on one mu of water. Warm water blending is not troublesome. A hot water bottle can be used to blend a sprayer with warm water.
“It is important to note that the farmers are now using the roller blinds to pull the grasshoppers and are not able to pull the flower buds. When pulling the sheds after the cloudy days turn fine, it is best to pull the grasshoppers up by one third. After the vegetables adapt to the environment, they gradually pull the grasshoppers to prevent the vegetables from wilting, Zhao Laiyu emphasized.
Second, warm water spraying anti-fruit "skin".
"Warm water spraying anti-flavored skin" is the second magical effect of Zhao Laiyu. Zhao Laiyu said that in the winter spraying, in order to prevent the humidity in the greenhouse from increasing, farmers often spray medicine before 10 o'clock in the morning and before 3 o'clock in the afternoon, and this time is precisely when the temperature in the greenhouse is the highest. very high. If you use cold water spray, it is easy to cause irritation to the fruit, causing it to appear molting. The use of warm water spray, the fruit does not appear the above symptoms.
"Of course, even if the use of warm water spray, after the spray of causal surface dew is greater, so when the release of the wind, it is necessary to pay attention to slow release, put a small breeze, otherwise, in the case of excessive rush, the fruit will still appear suede Phenomenon.†Zhao Laiyu added.
Third, after the vegetables are frozen, the spray water temperature is restored.
Zhao Laiyu said that in the cold winter months, there will always be some vegetable sheds that are unfavorable to heat insulation and cause frostbite. After the vegetables are frozen, if the remedial measures are correct, much of the damage can be avoided. According to his experience, vegetables could not be rushed to warm up after being frozen, but they should be sprayed with a warm water shed first because the water spray can increase the air humidity in the shed, stabilize the temperature of the shed, and prevent evaporation of moisture from the frozen vegetable tissue. Plant recovery. Note that the amount of sprayed warm water should be slightly larger after the plants are cold. It is advisable to spray 5-6 sprayers per acre. Zhao Laiyu said that the temperature of the sprayed warm water should be 20°C, and the water temperature should not be too high. If the water temperature is too high, only the frozen tissue will die.
Zhao Laiyu also told reporters that after the vegetables are frozen, they must pay attention to slow warming and avoid strong light, so as to avoid overheating or strong light, which will accelerate the wilting of plants. After the plants adapt to the environment, they should pour the water in time and use the quick-acting fertilizer with water to promote the recovery of the frozen plants as soon as possible. For example, high-nitrogen-type aromatic-enriched water-soluble fertilization, 8-10 kilograms per acre, has a significant effect on promoting plant rejuvenation.
