Please introduce the management methods of broccoli in autumn and winter, please refer to the following methods: watering slow seedling water for 1 / 2 times after planting, squatting seedlings for 3 / 4 times after ploughing and weeding, after 7 / 10 days, the weather turns cool, cauliflower enters the vigorous growth period, fertilizer and water should be strongly promoted, combined with watering, 10 kg urea per mu or 800 kg / 1000 kg of rotten manure should be applied alternately, 2 times in total, and no more fertilizer after buckle shed. Watering is to keep the soil moist, especially in the vigorous growth period of leaves and bulb hypertrophy period, there is no shortage of water, generally watering once every 5-7 days, after the middle of October, the temperature decreases gradually, and the amount of water and watering times should be controlled. Before the middle of October, set up the scaffolding, prepare the plastic film (preferably without dripping film), and cover the shed with plastic film in late October. The Beginning of Winter was covered with grass grass at night. In order to meet the water needs of the whole buckle shed, he watered it once before the buckle shed, and did not water it any more. The key to the management after buckling the shed is the temperature and air humidity. With high temperature and humidity, not only the plant is easy to get infected, but also the flower head is small, the yield is low and the quality is poor. Therefore, in the initial stage of buckling the shed, it is necessary to master the large ventilation measures of opening early and closing late. With the gradual decrease of external air temperature, the ventilation time and ventilation volume are reduced accordingly. Generally, the ventilation begins when the temperature in the shed reaches 15 ℃ in the morning, and the temperature of the shed is controlled not more than 25 ℃. In the afternoon, the ventilation is gradually reduced, and the tuyere is closed when the temperature of the shed drops to 15 ℃. In cold or cloudy days, it is necessary to cover the grass late and early, with no ventilation or less ventilation. Harvest is generally from the end of November to early December and should not be delayed so as not to cause frost injury.
