Soilless cultivation of Toona sinensis buds

The soilless cultivation of Toona sinensis sprouts should be selected in the industrial factory building, the temperature should be controlled at 15-30 degrees, and the cultivation containers generally choose light plastic vegetable seedling pots. The varieties mainly select a series of red Toona sinensis varieties with high purity, high purity, high germination rate and large seeds, which need medium intensity light and can be harvested with a seedling height of 8-12 cm. Next, let's introduce the soilless cultivation techniques of Toona sinensis buds.

1. Seed selection and soaking

A series of red Toona sinensis varieties with high purity, purity, germination rate and large seeds were selected. After drying and cleaning, the seeds were soaked in water with a water temperature of 18 ℃ and 25 ℃ for 24 hours, then germinated in a warm place of 20 ℃, covered with a moisturizing cloth and sprayed with water to ensure the suitable humidity of the seeds.

2. Control light and temperature

Toona sinensis seedlings need medium intensity light, the suitable temperature for growth is 20 ℃ 23 ℃, the lowest is not less than 15 ℃, and the highest is not higher than 30 Mel. Under the suitable temperature, the production cycle is 15 ℃ 18 days. Frequent irrigation with small water is the basic principle of replenishing water for seedling growth. Generally, microspray facilities or plant protection sprayers should be used 3 times a day, and the amount of water should be controlled by wetting the substrate in the seedling plate and not dripping a lot of water.

3. Disease prevention management

Unclean cleaning of seedling plate, poor seed quality, inappropriate temperature and humidity will lead to seed mildew and rotting roots and other phenomena. Prevention and control measures should mainly take corresponding measures to avoid the use of chemical pesticides.
