In recent days, some areas of our province have been hit by cold spells and temperatures have dropped sharply. Rape crops, wheat crops and other crops are facing varying degrees of "tests" --- Currently, rape is in a period of flowering and blooming, and low temperatures affect flowering, and fragmentation will occur. For wheat that is at the heading stage, low temperatures will affect fertilization. The fruit setting rate of the flowering fruit trees will be greatly affected. Early tea buds in tea gardens are bound to be frozen, and tea farmers will greatly reduce their income. While rice is sown and educated, low-temperature cold waves can cause bad seeds, rotting buds, and dead seedlings.
In order to minimize the damage caused by disasters, all localities must urgently take remedial measures in response to the current disaster situation and weather changes and earnestly do the following:
First, strengthen field management of rape, wheat, and vegetables. It is necessary to clear trenches quickly, reduce groundwater level and humidity in the field, and reduce the incidence of diseases; fully improve the efficiency of foliar spray, roots and leaves, increase grain weight, and strive to reduce yields; Potassium dihydrogen and borax solutions with a concentration of 0.2-0.3%.
Second, greenhouse vegetables, fruits and seedlings to do a good job of warming and freezing work. Close the film at night to prevent cold air from entering the shed and damaging the crop. After the cold wave, depending on the growth of crops, top-dressing is appropriate. At the same time, the melon seedlings can be transplanted to catch the fine weather and transplanted in time. Before the transplanting, the seedlings should be properly cultivated. Immediately after transplanting, they should be covered with plastic film and covered with a small shed to cover the heat, in order to promote the occurrence of new roots and to slow seedlings as soon as possible.
Third, we must strengthen the prevention and control of vegetable root rot, base rot, gray mold, leaf mold and other diseases. First, timely removal of diseased plants, diseased branches, diseased leaves, diseased flowers, and diseased fruits in the shed; second, use of the chlorothalonil-containing smoke agent or Acrylochlorogalactin-free tobacco smoke agent for fumigation during the rainy days; third, catch the fine weather; Actively select counterpart pesticides for prevention and control.
Fourth, do a good job of freezing or warming in orchards. For the orchard, it is necessary to adopt methods such as fumigation, cold-proofing, irrigating and mulching grass, whitening tree trunks, and fruit bagging as soon as possible to prevent freezing and warming. The frozen orchard must strengthen fertilizer and water management and increase available nitrogen fertilizer.
Fifth, strengthen seeding management of rice. Choose cold-resistant varieties, rush in the "cold tail warmer" suitable early sowing, cover film insulation, avoiding harm. If the cold has come, its resistance measures are to do a good job in water management, water temperature, rice after the two leaf stage before the cold resistance is slightly stronger, pay attention to ventilation, adhere to sunny sunny water, water is not on the car , Cloudy ditch, cloudy water drainage method. After two leaves, the cold-resistance is weak, shallow-water ground irrigation and daily-row night irrigation. When the cold wave invades, it is necessary to infuse deep water insulation. When falling hailstones and snow particles, it is necessary to infuse water in a timely manner. Water is kept in a timely manner. The duration of rainy days is long. The temperature in the field is similar to the water temperature. The water in Tangba Reservoir can be changed at noon to facilitate the increase. Warm qi. At night when the low-temperature and rainy days are over, we must pay attention to the prevention of frost. After a long period of low temperature and rain, rice seedlings are weak, and when it turns fine, paddy fields in the rice fields need to be deeply watered to absorb the imbalance of water absorption and transpiration, resulting in physiological drought. After the seedlings have recovered, they are gradually drained. At the same time, it is necessary to pay attention to the use of seedlings to raise the seedlings and cultivate the strong grasshoppers to ensure the planting area.
Sixth, tea must be picked and sold in time. After learning about climate change, we should pick up the spring tea that has germinated and picked shoots as soon as possible, and we must pay close attention to processing and selling. Before the advent of spring cold, we covered the tea gardens with weeds, straw and pruning branches. Can also be covered with shade nets. After the occurrence of cold injury, the lighter ones can be trimmed lightly to keep the picking surface as much as possible, while the heavier victims are deeply trimmed or heavily trimmed. At the same time, the foliar fertilizer was sprayed in time to promote the germination of buds and the growth of new shoots. Tea gardens with water sources and sprinkler equipment can be used to spray water to wash the cream. That is, when the night frost is harmful, spray water to wash away the frost that adheres to the buds of tea leaves.
