First, the preparation of culture medium: solanaceous fruit sowing can be used 90% perlite plus 10% culture soil dubbed. 60% carbonized chaff (washing once), yellow sand, and 10% culture soil can also be used. Melon sowing broth culture, with pure charring chaff as well. Transfer seedlings can use 70% perlite with 30% culture soil, or 70% rock husk plus 30% culture soil. Remember that the culture soil must be sterilized. Second, sowing and emergence: germination sprouting in the room (to seal the chamber), the volume is generally 8-10 square meters, indoor multi-layer nursery tray. Generally, an 8 cubic meter emergence room can meet 33.3 hectares of eggplant and fruit crops. More than 220 seedling disks (4030 cm) can be placed. The seeding rate in each seedling tray is roughly: 3 g of tomato, 6 g of pepper or eggplant, and 10 g of cucumber. During the emergence period, the room temperature is automatically controlled at about 30°C by electric heating. The time from sowing to emergence was: cucumber 2 days (days); tomatoes 3 to 4 days (days); peppers and eggplants 4-6 days (days). 3. Greening: Afforestation is carried out in greening greenhouses with good insulation properties. The area is generally 200-300 square meters, green beds (or green pools) are set up in the rooms, seedling trays are placed on the beds (pools), and electric heating is applied under them. Or put the seedling plate directly on the indoor ground, under which it is heated by electric heating, and a plastic shed is set on it for insulation. Afforestation bed release area should generally be 2-3 times more than the emergence area of ​​a disc area. When most of the sown seeds have just emerged, seedlings are planted in the afforestation room in a timely manner. The initial temperature is 25 to 30°C during the day and 15°C or more at night, after which the temperature is gradually lowered. After the seedlings are exposed to sunlight in the greening room, the color of the cotyledons turns green. In the greening period, the cotyledons of the seedlings are generally fully developed and greened. Tomato seedlings need 6 days (days), pepper and eggplant seedlings need 10d (days), cucumber seedlings need 4d (days). 4. Transfer seedlings: The seedlings are transplanted in the transplant seedlings, and their types vary depending on the conditions. Can use greenhouses, hotbeds, plastic impotence, plastic, greenhouses. However, the double-layer transplanted seedling shed was better, namely: a plastic shed 6-8m wide with a number of small bow sheds impregnated. After the greening period is over, the seedlings will be transplanted, and then the seedlings will be managed according to conventional methods.
