But systematic research concerning continuous mono-cropping grafted cucumber obstacle isn't reported. This paper systematically studied the effect of continuous cropping soil on grafted cucumber in aspect of its growth, yield and edaphon in pot experiments. Further more, root exudates of squash and grafted cucumber were collected by solution cultivate and adsorption of XAD-4 resins, and bioassay of the root exudates was did with cucumber and squash as receptors, studied allelopathy of grafted cucumber and squash root exudates on cucumber and squash , physiobiochemistry as well as.
