有数十种真菌和细菌都可以有效地控制杂草,但大多数都不能走出实验室而应用于实际,因为除草微生物不能长期存活或有效。美国农业研究局科学家发明了一种新方法:用糖来稳定微生物的细胞膜,在室温条件下可以使很大比例的微生物存活1.5～6个月,在冷冻条件下至少存活2年。通常有些微生物仅存 There are dozens of fungi and bacteria that control weeds effectively, but most can not go out of the laboratory and be used in practice because weeding microbes can not survive or be effective long term. US Department of Agricultural Research scientists have invented a new method: sugar to stabilize the cell membrane of microorganisms, at room temperature can make a large proportion of microorganisms survive 1.5 to 6 months, at least survive 2 years under freezing conditions. Usually some microorganisms only exist
