我们苗圃是一个经营多年的林区苗圃。随着造林面积的逐年增加,对于产苗量的需求也不断增多,因而,要求育苗面积不断扩大。在育苗生产中,除草是经营管理中一项关键而必要的措施,不仅季节性强,而且需要耗费大量的劳动力。随着育苗面积的不断扩大,除草也成了大问题。过去我们一直是采用人工除草,除草季节一般多是阴雨连绵,草苗齐长的季 Our nursery is a forest nursery for many years. With the increase of afforestation area year by year, the demand for seedling production is also increasing. Therefore, the area of ​​nursery seedlings needs to be continuously expanded.
