First, land selection and land preparation
Phellodendron amurense is a positive tree species, and likes the environment with sufficient light. Although the terrain requirements are not high, it can be planted in mountainous areas and plains in general. However, in order to make it grow well, it is best to choose a plot with deep and fertile soil layer, convenient irrigation and drainage and rich humus. First, after the land is selected, it can be combined with soil preparation, and 4,000-5,000 kg of manure can be applied per mu, and then dug up, and then carefully raked to make a flat land with a width of 1.5 meters.
Second, the sowing method
1. Mature fruits of Phellodendron amurense can be harvested at 10- 1 1. Pile it for about half a month after harvest, and then grind off the peel. After hand washing, take out the seeds and dry them, and then store them in a cool and ventilated place. Sowing time can be divided into spring sowing or autumn sowing. Spring sowing time is generally from March to May, and autumn sowing time is generally 165438. Before sowing, the seeds can be soaked in warm water for 24 hours, and then the seeds can be dressed with fine soil or wet sand to accelerate germination. After most seeds are broken, they should be drilled in furrows with a depth of 3 cm and a spacing of 30 cm. After sowing, the soil should be watered to keep it moist. In order to speed up the emergence of seedlings, plastic film or straw can be covered on the border for heat preservation and moisture retention, and the emergence time is about 40-50 days.
Third, thinning seedlings.
When the seedlings grow to 10cm, the soil should be kept moist at all times, but the seedlings should be thinned, the weak seedlings should be removed and the strong seedlings should be cultivated. From sowing to emergence, 1 time should be done to weed and loosen the soil, so that the seedlings can emerge smoothly. Before closing the ridge and loosening the soil, intertillage should be done twice to prevent weeds from robbing the field of nutrients. At seedling stage, fertilizer and water management should be strengthened and topdressing should be done 2-3 times.
Fourthly, seedling transplantation.
Seedlings can be transplanted when they grow to a year and the height of the seedlings is more than 50cm, usually before freezing and after defoliation in winter. The seedlings can be dug out, and the long roots can be cut off or transplanted with soil. When transplanting, the plant spacing should be controlled at 2 * 3m. When transplanting, the seedlings should be righted, and when the soil is half covered, the roots of the seedlings should be elongated, and then the soil should be leveled, compacted and watered. After transplanting, the survival rate of transplanting should be improved.
