摘　　要：本文采用萝卜子叶扩张法,萝卜、小麦和黄瓜的幼苗生长法,分别对原竹醋液和中和竹醋液进行室内生物活性筛选试验。结果表明: (1) 低浓度(<500 mg/L),具有植物生长调节剂功效,其功能与 2,4-D 类、激素类除草剂相似;高浓度竹醋液(2 000～5 000 mg/L)抑制作物生长,具有除草剂活性;也与植物生长调节剂GA3和6-BA具有相似的功效;(2)中和竹醋液的效果明显高于原竹醋液;(3)几种筛选指示物的敏感性从高到低的顺序为: 萝卜子叶>黄瓜根茎长>萝卜根茎长>小麦根茎长,其中对于黄瓜、萝卜和小麦,根长敏感性均高于茎长。对原竹醋液和中和竹醋液在苹果、柑橘、草莓等作物上进行应用试验。表明:竹醋液不仅显著地提高农林作物的产量;具有明显改善叶片质量,延长叶片寿命,提高果实硬度从而改善果实的储藏品质,改善果品的内在品质和外观品质等功能;在调节果实成熟期减少锈斑面积、落叶、落果和病害等方面均有显著作用。The bioactivity of original and neutralized bamboo vinegar are screened by means of radish cotyledon, radish seedling, wheat seedling and cucumber seedling in laboratory. The results showed： （1） The bamboo vinegar of low concentration （500 mg/L） effect as plant growth regulator stimulated growth similar to 2,4-D herbicides; those of high concentration （2000-5000 mg/L） inhibit growth as plant growth regular, the effect is similar to hormones herbicides, gibberellic acid （GA3） and 6-Benzylaminop-urine （6-BA）. （2） The bioactivity of neutralized bamboo vinegar is higher than that of original bamboo vinegar. （3） The sensitivity of tested plants for screen bioactivity from high to low expressed as follows： radish cotyledon 〉 cucumber seedling 〉 radish seedling 〉 wheat seedling. The sensitivity of root growth was higher than that of stem; The field experiments are carded out to test the stimulating effect of original and neutralized bamboo vinegar on apple, orange and strawberry in China .The results showed that Original bamboo vinegar and neutralized bamboo vinegar could add yield greatly; They could also improve leaf quality, prolong its natural life, increased the fruit hardness to improve its storage quality, make the fruit had better intrinsic quality and appearance; Original bamboo vinegar （OBV） and neutralized bamboo vinegar （NBV） could regulate maturing time of fruit and reduce rust spot, leaf falling, fruit dropping, disease.
