除草剂在杨树、柳树苗圃中的应用试验

An experiment on herbicides in poplar and willow nursery

试验表明采用使它隆+高效盖草能除草剂组合,在杨树、柳树当年扦插苗和截干苗圃中低位定向喷施,用药后30 d,对双子叶阔叶杂草和单子叶禾本科杂草防除效果为92.49%以上,对苗木生长无影响。较人工除草省时、省工,成本低,见效快。

Starane ＋ Gallant mixed formula were used to enhance the effect. The results showed that the herbicides can be combined in low-directional spraying in the cuttings nursery seedlings of poplar and willow. After 30ds, the control effects of dicotyledonous broadleaf weeds and single-cotyledon gramineous weeds were 92. 7% , and no damage on the seedling growth. Compared with manual weeding this method was labor-saving, lower cost and more efficient.
