In winter, the most feared for farmers is the sudden drop in temperature and the freezing of crops.
The main points of antifreeze:
Prevention is the main!
The important thing to say three times, the key point of antifreeze is: prevention! prevention! prevention!
If it has been frosted and caused frostbite, the loss is difficult to avoid. In order to minimize losses, everyone must cultivate the habit of preventing in advance.
Remember
The prevention of freezing damage is good, and the loss will be less!
Well, let's say that professionally, crops are generally affected by freezing. Because the crops are in a sub-healthy state, it is easy to cause cell wall and cell membrane rupture at low temperatures.
Therefore, timely supplementation of crop nutrition makes the crop more robust, so as to achieve better resistance to freezing damage and rapid recovery after freezing is critical.
This point, to say white is like a person, long health is less sick, heat will not catch a cold, cold will not have a fever. And some people are weak, as long as the temperature changes slightly, it is not a cold or a fever. As the saying goes, body bones can't. This is the truth.
Antifreeze scheme
If the crop is not strong enough, it will be indispensable to supplement phosphorus and potassium. Therefore, in the winter, more potassium dihydrogen phosphate is used for crops, which can prevent the freezing of winter crops and the weak leaves of plants.
In winter, the temperature is low, the crops absorb nutrients slowly, and proper adjustment of the crop is also critical. Especially after recovery from freezing. Regulators Xiaobian recommended brassinomycin.
Potassium dihydrogen phosphate and brassinolide are perfect match
This product, which may have been eliminated by many manufacturers and distributors, turned out to be the most cost-effective antifreeze package. Do you feel very strange?
Mainly because these things don't have much profit, and many people are not willing to promote. However, the antifreeze effect is still a drop.
In addition, as for the anti-freezing in the greenhouse, it is also possible to cool down the shed to release the smoke to achieve physical protection. However, everyone should pay attention to safety and don't burn the shed.
