Soil fertigation is suitable for selecting medium or slightly acidic loam with deep soil, loose and moist soil, rich organic matter, convenient drainage and irrigation, and good water retention and fertility. Before sowing, plunge the soil and use 1,000 kg of manure per acre. Made of a 1.5m wide high compartment with a depth of 20-25cm. Sorghum seedlings are small and have a short growing period and can be interplanted with other vegetables. Most of the production uses live broadcast, broadcast, broadcast can be. Spread 4 to 5 kg per acre. The seedlings were planted with 2 to 2.5 kilograms per mu with a spacing of 10 cm. To promote seedlings, soaking in warm water of 30°C～35°C for 24 hours before sowing, washing and then removing and germinating under the condition of 15°C～20°C, rinse with fresh water every day, and sow when the seeds are exposed to white in 3～4 days. In spring, sunny sowing is selected. After sowing, it is covered with a thin film. Water is properly controlled after emergence to maintain a suitable temperature and promote the seedlings to grow robustly. In the summer and autumn, the temperature is high, and after sowing, it is covered with a covering such as a sunshade omentum to keep the soil moist. Seedling period and seedling time, to ensure that the seedlings have a certain nutritional area. Field management keeps the soil moist after sowing until emergence, and can be planted in 6 to 7 days. After winter and spring sowing seedlings should be properly controlled watering, seedlings 2 to 3 true leaves when the thinning. Sowing, lobular wormwood 6 cm to see the side to stay strong seedlings, middle leaves or leaves of Artemisia halodendron 3 to 4 cm see Fang Liu Miao; drilled, large-leaved Chrysanthemum plants from the 5 cm, middle-leaved Chrysanthemum 4 cm, 3 cm fine Artemisia selengensis. Provide enough water to keep the soil moist. When the plant height is about 10 centimeters, it can recover 1 to 2 times of available nitrogen fertilizer with water, and the harvest begins when the plant height is about 20 centimeters. After the first knife is cut, the top dressing is watered and the side shoots are promoted. After 20 to 30 days, they are harvested. Every time, Mu is using 500 tons of human and animal manure and 3 to 4 kg of urea. Pest control 1. Disease. The main diseases are blight, leaf spot and sclerotia. Prevent blight, the focus should be to strengthen comprehensive agricultural control measures, pay attention to appropriate sowing, prevent sowing too dense, seedlings grow long; chemical control can be chlorothalonil wettable powder. Leaf spot disease should be subject to rotation and strengthen field management. 2. Pests. Insect pests mainly include vegetable worms and roundworms. The methods of prevention and control are the same as those of ordinary cultivated vegetables, but high and toxic pesticides should be avoided. Harvest at a time when plant height is 20 cm. Leave 2 to 3 leaves at the base of the stem to cut off to promote lateral branching. Xi'an complex bio-tech CO.,LTD. , https://www.complexpowder.com
