1. Variety selection

According to the market demand, excellent hybrid varieties such as "Zaojia 84-24" and "Taiwan Xiaolan" with early maturity, high yield, strong resistance and good quality were selected.

2. Sowing date

Generally, the seedling age in winter is about 30 days, which is raised in the form of greenhouse + greenhouse + plastic film, sowed in the middle and late November, transplanted in the middle and late December, and can be put on the market in the first ten days of April.

3. Seed treatment

Choose a sunny day before sowing to improve germination. Seed soaking: first immersed in 55 ℃ warm water for 30 minutes, soaked while stirring, and then soaked in room temperature water for 4 hours. Sowing: one week before sowing, the seedling shed is covered with film to keep warm, put the seedling nutrition bag, pour enough nutrient soil bottom water two days before sowing, and control the soil temperature above 25 ℃ to sow seeds.

4. Seedling stage management

The seedling bed should be moist before emergence, and after emergence to the first true leaf, water should be watered as little as possible, and then the soil should be properly watered according to the soil moisture, and the soil should be watered thoroughly if the soil is not white, and the same temperature water should be watered at noon. The main diseases in seedling stage after stopping watering 7 days before transplanting are sudden fall, standing blight and retting roots. Sprinkle on the bed with 10 grams of dimethazone powder and 10 kilograms of fine soil per square meter, or spray 72.2% Prik 400x solution to control quenching disease; use 5% Jinggangmycin water agent 1500 times liquid, or 10% rikuling water agent 1500 times liquid, or 15% carbendazim water agent 450x solution to control blight and retting roots. Spray 50% carbendazim 600 times solution into the field before planting.

5. Harvest in time.

According to the different maturity of varieties, the days after pollination were calculated according to the setting melon marks, and the maturity could be accurately judged and harvested in time when the days after fruit setting were reached.
