Abstract: Vegetable planting with intensive degree developed very fast in recent years． Investigation was conducted to explore the status of soil， water and fertilizer of greenhouse fruit vegetables in Beijing suburb． The resultshowed that excessive inputs of irrigation and fertilization， the unbalanced ratio of nutrient of N， P， K． The irrigationrate of fruit vegetable are 7 500 to 10 500 m3 /ha for farmers． The fertilization rate of tomato was at 1 206 kg N， 504kg P₂O₅ ， 782 kg K₂O and 1 426 kg N， 735 kg P₂O₅ ， 1 101 kg K₂O for cucumber， 1 298 kg N， 599 kg P₂O₅ ， 915 kgK₂O for pepper and 1 255 kg N， 631 kg P₂O₅ ， 958 kg K₂O for eggplant per hectare respectively． The selection of fertilizer type could not be paid attention and fertigation technique was not widespread used． The 62% of the organicfertilizer was bought from breeding factory directly and was composted with conventional method by partly farmers．And more than 50% farmers didn't know how to select the fertilizer． The ratio of 68% and 26% farmers fertilizedand irrigated with conditional methods， for example furrow irrigation． Heavy continuous obstacles were observed byfarmers as soil compaction， soil acidification， and soil secondary salinization were common due to excessive irrigationand fertilization management and continuous single crop for fruit vegetable． The knot-nematode was the most severeobstacle with the ratio of 29% of greenhouses， but only 11 % of the greenhouse was healthy without obstacles． Thelack of effective technique was the serve reason for continuous obstacles． So the synthesize technique was urgent tooptimal fertilization， irrigation and soil quality improvement． At the same time the effective technique demonstrationand dissimilation mode and management mechanism were very important and urgent on the small scale farms in China．
