Abstract：Using greenhouse cucumber as research object,four different companion planting models, cabbage,cauliflower,garlic and green Chinese onion,were designed to investigate the changes of rhizosphere soil nutrients of cucumber.The results showed that cauliflower,cabbage,green Chinese onion and garlic all had competition with cucumber on nitrate nitrogen.The cauliflower could promote the transformation of nitro-gen to ammonium nitrogen,while green Chinese onion could effectively absorb redundant ammonium nitrogen in the soil.The cabbage and cauliflower could release the phosphorus from fixed by soil,while green Chinese onion and garlic could speed up the uptake of available phosphorus in the soil.The cabbage could significantly increase the content of soil available potassium through releasing the potassium ion adsorbed by soil colloid, while garlic was conducive to eliminate the threat of high potassium.Thus,cabbage,cauliflower,garlic and green Chinese onion all could effectively reduce the soil salt concentration and prevent soil salinity.Compre-hensively considering,the garlic and green Chinese onion performed the best.
