【摘要】 了解韭菜、蕨、金荞麦和苜蓿对三七苗生长的影响,从而明确其是否能用于三七根腐病防治试验。分别用韭菜、蕨、金荞麦和苜蓿的水提液及其碎屑处理2年生盆栽三七,连续3个月对三七苗的株高、茎粗、叶长、叶宽四项指标进行测定。结果表明:蕨水提液对三七茎干的增粗有一定的抑制作用,但对株高和叶片生长无抑制作用;韭菜碎屑在施用初期对三七茎干的增粗有一定的抑制作用,施用2个月后这种抑制作用会逐渐减弱。金荞麦和苜蓿处理不会对三七的株高、茎粗、叶长、叶宽的生长产生不良影响。韭菜、金荞麦和苜蓿可用于三七根腐病生物防治筛选试验。更多还原

【Abstract】 In order to know effects of chive,fern,golden buckwheat and alfalfa on the growth of Panax notoginseng,these four plants aqueous extract and debris had been used on potted 2-year-old P. notoginseng. The results showed that fern aqueous extract inhabited growth of stem but height and leaves; at the beginning of one month chive debris inhabited growth of stem,but tow month after this inhibition will gradually weaken; golden buckwheat and alfalfa,whether aqueous extract or debris,had not negative effects on growth of height,stem,leaves of P. notoginseng. These results suggested that chive,golden buckwheat and alfalfa could be used for next screening test against root rot of P.notoginseng.更多还原
