根据白沙县细水牧场地形复杂、坡度大、多暴雨等自然特点,采用以化学除草、火烧等免耕法处理地面改良天然草地。初步结果表明,化学除草火烧免耕法改良海南中部山区天然草地的效果与机耕全垦的相似,而成本比全垦的减少约40%,且免耕法不受地形限制,使地表不受破坏,可利于水土保持。
According to the natural characteristics of the fine water pastures in Baisha County, such as complicated terrain, large slope and heavy rainstorms, the natural grassland is treated by the method of chemical weeding, fire and no-tillage to treat the ground. The preliminary results showed that the effect of chemical weeding and no-till improvement on the natural grassland in the mountainous area of central Hainan is similar to that of fully mechanized plowing and the cost is reduced by about 40% compared with that of the full reclamation and the no-tillage method is not restricted by the terrain and the surface is not damaged , Can help soil and water conservation.
