The seedlings were raised in loose and breathable sandy loam or loam with more humus. The nursery land should choose the moist land with convenient drainage and irrigation, leeward and certain shade conditions to sow and raise seedlings. According to the actual situation of the nursery site, plant ash or fully mature organic matter is applied at a rate of 500 kg per 667m 2, and then the topsoil is dug to a depth of 20 cm. After fine crushing and raking the soil, a flat or high bed with a width of 120 cm and 130 cm is made according to the topography and water humidity, and the border is suitable for early and evening sun, avoiding direct light at noon, and making ditches and ditches with a width of 30 cm and a depth of 15 cm. The ditches should communicate with each other, and there should be outlets for drainage.
