In response to the current drought, seedlings and sensation of garlic in our city, on February 14, the Municipal Agricultural Bureau issued the "Technical Opinions on Anti-drug and Promoting Spring Tubes of Garlic", requiring all districts to highlight an "early" word and seize the opportunity of spring temperature rise. Early management, drought-resistance and protection, focus on the drought-resistant and anti-freezing management of garlic plant on the ground to weaken and strengthen the loss to a minimum.
On February 13, the city's general snowfall, the average snowfall is about 2.7 mm, the drought has eased to some extent, but the drought situation is still very serious. According to the survey, the garlic in the city has been exposed to drought and freezing damage to the ground, and the damage to the underground roots is mild. According to preliminary statistics, the serious area affected by garlic in the city is about 37,000 mu, accounting for about 20% of the total area.
The opinion requires that the drought-resistant seedlings of garlic fields should be well done as early as possible. One is to take a foliar spray at the right time. Pay close attention to the weather changes. When the temperature rises and the daily average temperature is stable at 3 °C, you can spray the water on the ground with a sprayer to protect the seedlings. It can be sprayed 2-3 times, to ensure that the plants on the ground are sprayed evenly and there is no water on the film. The second is to timely pour "protection water". For plots that have a serious impact on the normal growth of garlic due to drought and freezing damage, the average temperature of the day is stable at 5 °C, and it can be quickly infiltrated after watering in the daytime, and it is necessary to pay close attention to watering and seedling protection. When watering, care should be taken to pour small water under the membrane to avoid flooding of large water, accumulation of water on the surface, freezing of garlic on the ground at night, and sprinkler irrigation in places where sprinkler irrigation is required. The third is the appropriate application of nitrogen fertilizer. For frozen yellow seedlings, dead seedlings or de-fermented garlic fields due to drought, about 10 kg of urea or other quick-acting fertilizer should be applied per acre combined with watering to promote the normal return of garlic. For the winter and spring drought that may occur this year, we must pay attention to the principle of proper amount and application when fertilizing, to avoid drought and dry seedling after fertilization.
The opinion also suggested that it is necessary to comprehensively control pests and diseases. As the temperature rises after the greening, the weeds will increase and must be removed in time to prevent the weeds from competing for nutrients and arching the mulch. At the same time, due to the weak seedlings and poor resistance this year, the probability of occurrence of various pests and diseases will be higher than normal after the temperature rises. All districts must do a good job in measuring and reporting, prepare medicines and medicines early, and implement comprehensive prevention and control. Also pay attention to weather changes and prevent early spring frost damage.
