In the early stage of growth, the autumn spinach in the greenhouse can be grown without shed film (that is, open field growth), and the greenhouse film growth is carried out before the frost. The harvesting time is in early November. The economic benefits of planting autumn spinach in greenhouses are considerable and the management methods are simple. The specific practices are as follows: The varieties are selected from the varieties of spine hybrid rice, spinach 18, omnipotent, and spinach crown, which have strong cold tolerance, fast growth rate, high yield and strong disease resistance. The whole land is made to smash the vegetable land and loosen it once. 667m2 high-quality farmyard manure 5000kg, the fertility is poor, then apply the appropriate amount of 45% ternary compound fertilizer or 15% Saco. Mix the organic fertilizer with the buckwheat and smooth the kneading dough. Inter-shed management 1. Temperature. Before the frost, the greenhouse film is usually buckled in the middle and late September. The mask of the greenhouse will be uncovered during the day and night. Later, as the outside temperature decreases, the skirt will be uncovered during the day and closed at night. When the temperature is lowered again, the skirt is sealed during the day. In case of high temperature, open the shed door and the upper air outlet for ventilation. 2. Moisture. 4 to 5 days after sowing, the seedlings should be released, and watered in time before and after emergence to ensure the surface of the bauxite is moist to promote the growth of spinach. Water should be poured once 2 to 3 days before the film is shackled. After the film is buckled, it can be watered before harvesting. 3. Disease prevention and treatment. Autumn greenhouse spinach is easy to get downy mildew. After watering for 2 to 3 days before decanting the greenhouse film, spray 72% sulphuric acid, manganese, zinc, manganese, zinc (kelu) 600 to 800 times. After the shed, the downy mildew disease was found to be 10% bacteriostatic agent 300-400 g / ha, once every 7-8 days, continuous control 2 to 3 times, can effectively inhibit the spread of downy mildew .
