| 摘 要： | 盆栽与田间试验研究黄瓜连作对土壤理化性状及生物活性的影响结果表明,黄瓜连作后土壤次生盐渍化加重,P过剩,K则消耗过多,造成养分不平衡;土壤微生物区系改变,微生物由“细菌型”土壤向“真菌型”土壤转化,土传病虫害加重,线虫密度高达4.38条/g土。

| Abstract: | The effects of cucumber continuous cropping on the soil physi-chemical characters and biology activities were studied through pot and field trials.The results show that cucumber continuous cropping makes the soil secondary salinization heavy;makes the soil nutrition unbalanced,i.e.P is excessive and K content low;and also makes the bacterium-type soil transferred into the epiphyte-type soil,causing the heavy soil root-knot nematode disease,being 4.38 pieces of root-knot nematode in one gram soil. |
