紫穗槐(棉槐)直播造林可减少育苗工序,降低造林成本,苗木长势良好。播前整地:在地形变化小、地势平坦、土质条件好、坡度小的地方,用拖拉机全面深翻。在地块较小、地形变化大,水土冲刷严重的地区,可用拖拉机翻耕宽1.5～2.0米的翻耕带,带距一般以2～3米为宜。在土质干燥、石块较多、土层比较薄的地方,用拖拉机牵引开沟犁往返走一次,筑起宽度为1～1.2米、高40～50厘米的水平埂,用人工打碎土块,压实,以便在埂上直播造林。
Amorpha fruticosa (cotton acacia) direct seeding afforestation can reduce nursery procedures, reduce afforestation costs, seedlings grow well. Pre-sowing site preparation: small changes in the terrain, flat terrain, good soil conditions, small slopes, with a full deep tractor. In small plots, terrain changes, soil erosion serious areas, tractors can be tilled 1.5 to 2.0 m wide tillage belt with a pitch of 2 to 3 meters is appropriate. In the dry soil, more stones, the soil is relatively thin place, tractor plow ditches to and fro one time, build a width of 1 to 1.2 meters, 40 to 50 cm high level of 埂, with artificial broken clods , Compacted, in order to broadcast afforestation on the 埂.
