Technology of three-dimensional rapid planting of Toona sinensis

1. When the average outdoor temperature is 18 ℃, it can be produced in the open field, but it should be properly shaded, avoided direct light, sprayed more water, and maintained a proper temperature. Measures such as shading, spraying and cooling should be adopted in the hot season in midsummer to keep the air temperature within 35 ℃, otherwise the growth will stop. It can be produced in greenhouse and greenhouse in winter, early spring and late autumn. The optimum temperature for buds of Toona sinensis is about 26 ℃.

2. Starting from saving land, three-dimensional cultivation can be adopted. The cultivation frame is made of angle iron, steel bar, bamboo rod, wood stick and other materials. There are 3 ~ 5 layers in cultivation, and the distance between each layer is 30 cm ~ 40 cm. The width depends on the length of seedling tray. In order to facilitate operation, the height is generally not more than 1.65 meters.

3. It is better to use light plastic products in the seedling tray. This reduces the load-bearing capacity of the planting rack, and wooden plates are also available. The size of the seedling plate is 60 cm long, 25 cm wide and 5 cm high for easy movement and harvest.

4. The cultivated soil often washes sand with pure water.

5. Spraying equipment, the growth cycle of Toona sinensis buds is short, and the water holding capacity in the substrate has basically met the water needs of the buds during the whole growth period. After the buds grow out of the substrate, they should be sprayed regularly and do not splash water.

6. The choice of site should be determined according to the seasonal change. Wang Baihui
