Key points of Tomato Seedling raising techniques in Autumn and Winter

1. Selection of improved varieties: early early sowing selection of early easy fruit setting, low temperature tolerance, weak light tolerance, suitable close planting, early maturity, high yield, high quality and strong disease resistance. Each bottle of new high-fat membrane mother liquid is generally diluted 5ml 10kg liquid, after soaking the seeds, it can be removed and dried. It can keep heat, keep moisture, absorb swelling, improve seed germination rate and make seedlings strong. Repelling underground pests and isolating virus infection. It can also be mixed with seed coating agent.

two。 Seedling bed preparation: during the tomato seedling raising period in autumn and winter in solar greenhouse, the seedling bed should have the conditions of anti-rain and waterlogging, ventilation and cooling, and the seedlings must be covered with thin film in order to adapt to the greenhouse conditions. Apply rotten farm manure 20 kg per square meter, turn 10 cm deep, rake flat border surface.

3. Sowing: the seedling border is irrigated with enough water, and after the water is seeped, it is sown in holes with a row spacing of 10 cm to 12 cm, with 2 to 3 seeds in each hole, covering 1 cm thick nutritious soil. Keep the border moist before emergence.

4. Seedling management: leave one strong seedling in each hole after emergence, and cut off the rest. Avoid drought and keep dry and rheumatic during the seedling period. New high lipid membrane + insecticide was sprayed every 7 days to prevent the spread of virus disease. Tomato seedlings in autumn and winter had 4 ~ 5 leaves in about 30 days. Strong seedlings of suitable age with a height of 20-25 cm.
