| 摘 要： | 利用盆栽试验研究大蒜干样还田后,对日光温室黄瓜生长及土壤生化特性的影响。结果表明:添加大蒜干样后,显著增加黄瓜植株的鲜重,且与添加量成正比;在黄瓜的整个生长期,增加了细菌和放线菌的数量。当结果期大蒜的添加量为3.0%时,减少了真菌和镰刀菌的数量,并提高了土壤B/F(细菌+放线菌/真菌)值,优化了土壤微生物区系;而随着黄瓜的生长,促进黄瓜幼苗期根际土壤多酚氧化酶、蔗糖酶、尿酶和过氧化氢酶的活性。当结果期大蒜添加量大于2.0%时,对4种土壤酶具有显著的促进作用,使土壤环境有利于黄瓜生长。

| Abstract: | This study was focused on the impacts of garlic amendment on cucumber growth and soil biological properties by potted tests in a greenhouse.The results indicated that adding garlic residue significantly improved cucumber growth.The fresh weight of cucumber was positivly correlated with the added quantity of garlic residues.The numbers of bacteria and actinomycetes were enhanced due to the addition in the whole growth period of cucumber.However,adding 3% garlic residue decreased the number of fungi and fusar... |
