First, the choice of species. Choose varieties with strong cold resistance, thick leaves, and dark green leaves.
Second, soil preparation for basal fertilizer. If the fruit crops are grown in the Shangyu, this can also be done without applying organic fertilizer. Sprinkle some NPK fertilizer. The specific approach is to loosen the land and loosen it again. Disperse 400-500 g evenly every 5 m2. If the Shangyu produces vegetables and the soil is lack of fertilizer, the average quality of farmhouse manure in Mushi is about 5,000 kilograms. Mix the organic fertilizer with the alumina and turn it evenly to make it flat.
Third, sowing.
(1) The northern region is generally planted after October 1st.
(2) The sowing amount is about 50 grams of pure seeds of 5 square meters. If the seeds have low purity and impurities, they can be used to remove impurities and pods, leaving the seeds sown to ensure the emergence of seedlings and growth.
Fourth, management after sowing.
(1) Temperature: After October 1st, with the change of solar terms, the temperature during the day is still high. During the day, both sides of the film must be opened. After the temperature decreases in nature, the film should be covered at night. The temperature will decrease again and the feet will be sealed during the day. If you encounter high temperatures in the future, you can open the greenhouse door for proper ventilation.
(2) Moisture: Qi seedlings will be produced 4-5 days after sowing, and generally two days after sowing, watering is needed to ensure that the seedlings are neat and tidy. Watering is also required after emergence. In short, it is necessary to ensure that the surface of rammed soil is moist to promote the growth of spinach.
(3) Pest control: In the autumn greenhouse, spinach is susceptible to downy mildew, and prevention and control are very important. Pests mainly include whitefly, cabbage caterpillar, and diamondback moth.
Control methods: After the film is watered, an agent for preventing downy mildew should be sprayed once, such as 2% cream urea manganese zinc 600-800 times liquid. If a downy mildew occurs after the shed, it is best to use a smoke agent to prevent and control it. For example, if 10% chlorothalonil smoke agent is used every time 300-400 grams per acre, continuous control 2-3 times can effectively inhibit downy mildew. Spread. Pests can choose nitenpyram, Aketai spray control.
