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。
In this paper, radish cotyledon dilation method, radish, wheat and cucumber seedling growth method, respectively, the original bamboo vinegar and bamboo vinegar in the indoor bio-activity screening test. The results showed that: (1) Low concentration (<500 mg / L) had the effect of plant growth regulators and its function was similar to that of 2,4-D and hormone herbicides; high concentration of bamboo vinegar (2 000-5 000 (2) the effect of neutralizing bamboo vinegar is obviously higher than that of original bamboo vinegar; (3) The sensitivity of several screening indicators from high to low order: radish cotyledons> cucumber rhizome> radish rhizome> wheat rhizome length, which cucumber, radish and wheat, root length sensitivity were higher than the stem length. The original bamboo vinegar and bamboo vinegar in the apple, citrus, strawberries and other crops on the application test. The results showed that: bamboo vinegar not only significantly increase the yield of agricultural and forestry crops; has significantly improved leaf quality, extend leaf life, improve the hardness of fruits to improve the storage quality of fruits, improve the intrinsic quality of fruits and appearance quality and other functions; Reduce the area of rust spots, deciduous, fruit drop and disease have a significant role.
