一、选地整地通常利用荒山坡、梯田边、堤坝、河旁、沟沿、宅旁等零星空闲地栽培,但改野生为家种时,应选择向阳、土层深厚、土质疏松肥沃的黑沙泥或黄沙泥土为好。翻整土地一般较粗放,有条件者可开坑松土,每个坑深50厘米,直径33厘米,坑内施入垃圾、厩肥等底肥,以待栽种。二、繁殖方法可用扦插或种子播种繁殖,但目前以扦插繁殖为主。扦插繁殖,可分直插和育苗插两种。在春秋两季阴雨天,选一、二年生无病虫害的壮枝条,剪成30～40厘米长,去掉下部叶片,直接插到栽培地挖好的土坑里,坑距120～150厘米,每坑插5～6根,分散成扇面形斜插坑内,地上露出10～15厘米,填土压实,遇天旱应浇水,以提高成活率。扦插育苗,应选近水源的地 First, the site preparation and land preparation usually uses sparse slopes, terraced fields, embankments, riversides, ditch along the house, etc., and cultivated in sporadic space. However, when changing the wild species, we should choose dark sandy and fertile sandy soils that are sunny, deep in soil, and fertile. Mud or yellow sand soil is better. The rectification of land is generally more extensive, and those who have conditions can open pits to loosen the soil. Each pit is 50 cm deep and 33 cm in diameter. The bottom of the pit is filled with garbage, fertilizer and other base fertilizers to be planted. Second, the propagation method can be used for cuttings or seed sowing, but cutting propagation is the main method. Cutting propagation, can be divided into two kinds of straight insertion and seedling insertion. In the rainy days of spring and autumn, select strong branches without disease and pests in one and two years, cut them into 30-40 cm long, remove the lower leaves, and insert them directly into the excavated earth pits. The pits are 120-150 cm long, each pit. Insert 5 to 6, disperse into a fan-shaped oblique insertion pit, exposing 10 to 15 cm above the ground, compaction of soil, watering in case of drought, in order to improve the survival rate. Cutting seedlings, should be selected near the source of water
