At present, most of the vegetables in the sheds have been planted, and the seeds have already begun to bloom. Here, we remind farmers to guard against the cold. "Cooling down the cold" refers to an abnormal weather phenomenon in which the temperature in the seasons that should have been warmed up after the spring warming suddenly dropped from zero to minus one to two degrees Celsius, causing some vegetables to rot, die, fall and fall, and convulsions. Harm. According to a special expert from the newspaper, Jiang Yisi, this disastrous weather mostly occurs from late March to early April. To deal with the damage caused by the cold in spring, vegetable farmers should generally adopt the following countermeasures: First, we must strengthen insulation. For vegetables that were planted at the beginning of February and early March, do not remove the agricultural film in the shed prematurely. Vegetables grown at this stage generally have to be installed with sheds and small greenhouses and other layers of agricultural film to keep warm. As the weather turns warm, some vegetable farmers looked at the temperature in the recent period of time is relatively stable. To facilitate the operation, it is necessary to withdraw early. After removing the agricultural film, it is recommended that the vegetable cultivators first remove the small shed inside, leaving the second or even three layers of agricultural film ready for the second half of the year to cover it again. It is also necessary to pay close attention to the weather forecast and wait until the temperature becomes stable before removing it completely. . For the vegetable seedlings that have just been planted, it is advisable to set up 1-2 layers of small sheds in the sheds to prevent the spring and cold, and also to add grass and grass to the outside of the arch shed to protect the wind from the cold. Can also be implemented before the cold watering insulation, because the heat capacity of water is large, before the cold watering, can effectively prevent freezing damage. At the same time, the shed can be temporarily covered with wheat straw, straw, etc., but also can be appropriately increased temperature. Secondly, it is necessary to control fertilizer and water, reduce the amount of nitrogen fertilizer, reduce the humidity within the chamber, enhance light, prevent prosperous growth, use the high temperature in recent days, strengthen ventilation, cultivate robust plants, implement low-temperature hardening, and spray cold and antifreeze to kill. Ice crystals enhance cold resistance. For plants or seedlings with prosperous growth, 750-1000 times the amount of auxin can be sprayed to control the growth rate and improve the cold resistance. Once again, if the fruits that are in flowering are affected by the cold of late, we must promptly spray 6,000 times more love and nuclear acid (green wind 95) to alleviate the hazards; if the newly planted seedlings are subjected to freezing damage, it is best to properly cover After some time in the shade, the leaves were sprayed with love and nucleotides to quench the frost damage.
