First, land preparation and land preparation
It is advisable to choose sun-dried, fertile and loose, well-drained loam or sandy loam. Before the ploughing, 2500~3000kg of compost is applied per acre, and the depth is 20~25cm. The hoe is fine and flat, and it is made into sorghum, 1.5m wide, 15cm high, and 30cm drainage ditch on both sides.
Second, planting
On the whole surface, the row spacing is 1.3m, the plant spacing is 1m, the depth of the hole is 40~50cm, and the hole diameter is 50~60cm. Dig the lower layer of hard soil, apply appropriate amount of manure and cake fertilizer as base fertilizer, and cover the soil 5~10cm. Then plant the seedlings into the holes, and lay the roots flat on the sides to make them stretch, cover the dry loose soil, and when half filled, use the feet to be solid. After filling the soil, compact it again, and the planting depth is slightly deeper than the original soil mark. Do not flatten the surface of the hole, leave a shallow pit to store water, and finally pour the root water, cover a thin layer of fine soil.
Planting in the early spring after the germination of the new shoots to March, the seedlings should be transplanted with the soil mass, too late to be carried out, otherwise it is not easy to survive. If transplanted from deciduous to pre-spring germination, the seedlings can be excavated with bare roots, without soil mass, but the lateral root length should be no less than 20cm, otherwise it is not easy to survive.
