After the autumn of autumn
The leek prefers cool weather. After the beginning of autumn, the temperature gradually decreases and the temperature difference between day and night increases. At this time, strengthening the management will help the leek grow and accumulate nutrients. The first ridge ditch, and then 50 kg of cake fertilizer per acre, high-quality farm fertilizer 750 kg, 20 kg compound fertilizer. Cover soil after fertilization and pour water twice.
After the cold dew stop water control
After cold dew, the weather gradually became cold and the leeks grew slowly. At this time, watering and topdressing should be stopped so that the leeks could be fed back to the roots and nutrients accumulated.
Wind barrier erected after frost
After the frost falls, a wind barrier that is tilted north and 1.3-1.5 meters high is set up at the front of the south side of the Dong to reduce the temperature of the aphid and force the leek to sleep earlier, which reduces nutrient consumption. After the beginning of winter, the wind barrier was changed to 15 degrees to the south, turning the Nanzhao into an ambiguity.
After the winter coverage management
Before covering, remove all the dead leaves and other debris in the locust, cut off the dry pods, and apply 20 kg of urea per acre in combination with watering. After seeping through the water, a small arch shed was used to cover the film and grasshoppers. The grasshoppers were uncovered at 9:00 a.m. and covered at 2 p.m., and they were darkened by light for about 5 hours. After 3-5 days, the leek sprouted and the film was uncovered, covering the soil 2-3 times with a total thickness of 5-10 cm. In late November, when the leek is 35 centimeters high, the first knife is cut and watered and fertilized after cutting.
