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 rcot-knot nematode disease, being 4.38 pieces of mot knot nematode in one gram soil.
