High yields of vegetables and breeding seedlings are the key. To cultivate robust seedlings of Solanum species, the following aspects should be taken into consideration: 1. Cultivation of cultivated soil: Take soil from the land where we planted green onions, garlic or no eggplant vegetables in recent years, and then press the vegetable garden soil. , Fermented horse dung, manure all one-third mix well, and then add the equivalent of culture soil weight 0.1-0.2% made of superphosphate with nutrient soil filled into the nursery bed, solid leveling. Second, the seed disinfection: You can use 55 °C hot water immersion, or soaked with 10% aqueous solution of trisodium phosphate for 20-30 minutes, remove and rinse after clean water, and then germination sowing. Third, seed treatment: magnetic seeds can be magnetized seed, can also be multi-functional oxygen water treatment seed, but also can be used "863 bio-assisted device" to make the seed nanometer processing, after any of the above three methods or at the same time After the activity of the enzyme in the seed was enhanced, the disease resistance was enhanced, and the early germination was 3-4 days. The seedling grew vigorously and quickly. Fourth, appropriate sowing: According to the planting period to calculate the appropriate sowing period. Before seeding, the seedbed is poured with plantar water, then sowed and covered with a plastic film. Fifth, temperature management: generally sown until the emergence of 25-30 °C, after the emergence of 20-22 °C during the day, night 15-16 °C, transplanting to 25-30 °C before the slow seedlings, 20-30 °C during the day after the slow seedlings, 15-18 °C at night. 7-10 days before planting for cryogenic exercise. Sixth, light management: Solanaceous vegetables like strong light, grow strong under strong light, easy light grows ill under weak light. The main approach is: 1 The glass or plastic film should be kept clean to reduce the accumulation of water droplets and dust. 2 As far as the temperature is guaranteed, try to cover it as soon as possible. 3 hangs the light curtain. 4 The cloudy days also expose the blind. VII. Moisture Management: Before planting, planting water before planting; Do not water immediately after planting; Pour water once during emergence; Watering from one end at a time, do not pour water back and forth, each time after watering, leave the leaves dry. At the time, sprinkle some dry soil or plant ash to facilitate the protection of oysters, prevent the knot from lowering the temperature, and avoid flooding with snow. 8. Pre-planting seedlings: During the 5-7 days prior to planting, nighttime cryogenic exercises are performed. If the seedlings are too tender in order to avoid cold damage, they can be treated with a higher temperature of 7-10 °C for several days, and then further hardening the seedlings, tomatoes 3-5 °C, eggplant, pepper 8-11 °C, practice time 3 - For 5 days, the vegetables that are cultivated at low temperatures can improve their adaptability. They can tolerate general frost and plant seedlings quickly after being planted. Can also be used to enlarge the seedling distance, uncover the sun drying seedlings and other methods to promote strong seedlings, improve resistance to stress. Today is the time for the nursery to raise seedlings. Farmers are asked to enrich their knowledge of vegetable breeding and seedlings and prepare for the next year's nursery.
