Abstract:
Taking ground cover plant Tagetes patula L.as the research object，the effect of its water extraction liquid of different parts on itself and microbial quantity and enzymatic activity were studied.The results showed that its effect tendency on plant height was the control＞water extraction liquid of leaf＞water extraction liquid of flower＞water extraction liquid of stem.The tendency of its effect on crown breadth was corresponded with the stem diameter，water extraction liquid of flower＞water extraction liquid of stem＞the control＞water extraction liquid of leaf.The effect on the euphylla tiller number was the water extraction liquid was higher than the control.Furthermore，the effect on flower diameter was the control was higher than the water extraction liquid.The effect on the dry weight of the over ground plant was the water extraction liquid was higher than the control，the tendency was water extraction liquid of flower＞water extraction liquid of leaf＞water extraction liquid of stem＞the control.The tendency of the effect on the dry weight of the underground plant was water extraction liquid of flower＞the control＞water extraction liquid of stem＞water extraction liquid of leaf.The effect of the water extraction liquid treatment of the different part of Tagetes patula L.on the quantity and quality of soil microorganism by water extraction liquid of flower treatment promoted the increase of soil bacterium，actinomycetes and fungus compared with the control.Nevertheless，the treatment of water extraction liquid of stem inhibited the increase of soil bacterium，actinomycetes and fungus compared with the control.Moreover，the treatment of water extraction liquid of leaf inhibited the increase of soil bacterium，actinomycetes and promoted the increase of fungus.The tendency of B/F value was water extraction liquid of flower＞the control＞water extraction liquid of stem＞water extraction liquid of leaf.The effect of the water extraction liquid treatment of the different part of Tagetes patula L.on series of soil enzyme activity presented different promotion or inhibition，especially the promotion ability of water extraction liquid of flower was the best.The consequence showed that the water extraction liquid of the different parts of Tagetes patula L.had obvious allelopathy.It did not effect the growth of Tagetes patula L.after picking its flower.In addition，it can be transplanted to the field directly.
