对长泰县岩溪国有林场杉木幼林地喷施草甘膦后土壤变化的初步研究表明 ,喷施地在根系密集区其土壤的物理性质和化学性质都有不同程度的变化。土壤容重值下降 ,而有机质、全氮、碱解氮、速效钾和土壤自然含水率都有不同程度的增加 ,但土壤 pH值微小下降。喷施草甘膦的幼林杉木与用人工除草深翻杉木 ,生长情况相似
A preliminary study on the soil changes after the application of glyphosate in the young Chinese fir forest at Yanxi National Forest Farm in Changtai County showed that the physical and chemical properties of the soil in the densely populated areas varied in varying degrees. Soil bulk density decreased, while organic matter, total nitrogen, available nitrogen, available potassium and soil natural moisture content increased in varying degrees, but soil pH decreased slightly. Growth of young young Chinese fir sprayed with glyphosate was similar to that of manual mulching of Chinese fir
