Toona sinensis seeds are small, the seed coat is hard, the membrane wings are long, the water absorption capacity is poor, and it is not easy to germinate. These are difficult problems when planting Toona sinensis, so we should make good preparations for seedling raising before breeding. The specific requirements for seedling raising are as follows:

Every year around March, it is the day when spring blooms, and this time is also the best time to soak Toona sinensis seeds. It is necessary to soak the seeds in warm water of 35-40 degrees for about 24 hours, then take them out and put them in a wet cloth bag to accelerate germination at a constant temperature. Keep the temperature at about 20-25 degrees, water twice a day, and turn over the wet bag once each time, with 50% seeds.

Step 3 accelerate germination

Toona sinensis seeds can be evenly mixed with river sand according to the ratio of 1 2, and a certain amount of clear water can be added. Pay attention to not too much water, and how to control the amount of water and water. Grab a handful of river sand mixed with seeds with your hands, hold it tightly with your fingers, and then open your fingers. River sand mixed with seeds will naturally disperse.

This is the best humidity. Put the river sand mixed with seeds in a push and make it into the shape of steamed bread. Give it a little water every day. Stir well when watering, and water it 1 time a day. When 70% of the seeds grow white and bud heads, they can be planted.

4, seedbed preparation

The "seedbed" should be chosen in a flat place as a nursery place. About 4000-4500 kilograms of organic fertilizer should be applied to the bottom of the seedbed. After fertilization and leveling, the land should be plowed every 20 cm. After sowing, the seeds should be covered with plastic film to ensure early emergence (about 2-2.5 kilograms of Toona sinensis seedlings per mu).
