Come along with the editor to take a look at the detailed introduction.
1. Land selection and land preparation
Phellodendron amurense is a sun-loving tree species and prefers an environment with sufficient light. It has no strict requirements for terrain and can be planted in both mountainous areas and plains, but plots with deep and fertile soil, convenient irrigation and drainage, and rich in humus are still preferable. After selecting the plot, apply 4000-5000 kg of barnyard manure per mu during land preparation, plow deeply to turn it in, rake finely and level, and make flat beds 1.5 m wide.
2. Sowing
Harvest mature fruit in October-November. After harvesting, pile it for about half a month, then rub off the fruit skin, rinse by hand, take the seeds and dry them, and store them in a cool and ventilated place. It can be sown in spring or autumn. Spring sowing is from March to May, and autumn sowing is from November to December. Before sowing, soak the seeds in warm water for 24 hours, then mix the seeds with fine soil or wet sand to promote germination. After most seeds have cracked, sow in drills in furrows 3 cm deep and 30 cm apart. After sowing, water to keep the soil moist. To speed up emergence, cover the bed surface with plastic film or rice straw to keep warm and moist. Seedlings emerge in about 40-50 days.
3. Seedling raising
Keep the soil moist at all times during emergence, but when the seedlings grow to 10 cm, thin them out, remove weak seedlings, and cultivate strong seedlings. From sowing to emergence, weed and loosen the soil once to allow smooth emergence, and before the rows close, carry out intertillage and weeding twice so that the soil is loose and there are no weeds in the field competing for nutrients. During the seedling stage, also strengthen fertilizer and water management, and topdress 2-3 times, applying 20 kg of diammonium phosphate per mu each time. After sowing, water frequently to keep the soil moist so that it germinates as soon as possible.
4. Transplanting
When the seedlings have grown for one year and the seedling height is above 50 cm, they can be transplanted. This is generally done before winter freezing and after leaf fall. Dig out the seedlings, and the overly long roots may be appropriately pruned, or transplant with soil. When transplanting, control the plant spacing and row spacing at 2×3 m. When transplanting, hold the sapling upright, and when half of the soil has been filled, lift the sapling gently so that the root system spreads out, then fill the soil, level it, press it firm, and water. After transplanting, keep the soil moist to increase the transplanting survival rate.
