First, soaking The dried seeds were immersed in warm water of 55 °C ~ 60 °C for 15 minutes, and stirring constantly, and soaking in 28 °C ~ 30 °C water for about 6 hours. Second, germination Pack the soaked seeds with a damp cloth, keep the temperature at 25 °C ~ 30 °C during the day and 18 °C ~ 20 °C at night, and select 80% of the seeds for whitening and sunny sowing. In order to ensure that the seed does not carry pathogens, it can also be treated with medicaments, for example: use 1 million 500 times of streptomycin sulfate to soak seeds for 2 hours, wash and soak seeds for 3 hours to germinate. Sowing period is in late February and early March. Third, nursery nutrition soil preparation The principle of nutrient soil selection is: good air permeability, heat preservation, moisturizing, water seepage, the ratio of matrix and organic fertilizer is 3:2, and the added organic fertilizer must be fully decomposed. In addition, 100 g of 50% carbendazim powder and 1 kg of compound fertilizer were added to each nutrient soil matrix, mixed evenly, and placed in a plastic mortar. IV. Seedling management Seedlings are raised in the greenhouse, and the indoor temperature is maintained at 28 °C to 32 °C during the day and 17 °C to 20 °C at night. In order to prevent the occurrence of disease, after the emergence of Qimiao, use 72.2% Preclosure 700 times to irrigate roots. The seedlings were planted 7 days before planting, with daytime temperatures of 20 °C to 22 °C and nights of 10 °C to 13 °C (gradually falling to 8 °C to 10 °C). Seedling age 30-35 days, 3 leaves and 1 heart, spraying 0.1% multiple compound fertilizer on foliar once.
