Shandong Province is the main vegetable producing region in China,with its greenhouse coverage account ing for nearly 50% of the country's.In the period from 1994 to 1997,the mean annual fertilization rate on greenhouse vegetable in Shandong was N 1 351 kg hm^-2,P₂O₅ 1 701 kg hm^-2 and K₂O 539.6 kg hm^-2.In comparison with the application rate in 2004,the application rates of nitrogen and phosphorus fertilizers decreased,but of potassium fertilizer and organic manure in creased significantly in 2007.Apparent balance of soil nutrients showed that soil N,P and K was gaining by a large margin.Re gardless of high fertilization rates,fertilizer recovery rates were still quite low.The apparent fertilizer recovery rate of nitrogen,phosphorus and potassium was 21 33%,2 82% and 61 34%,respectively,in greenhouses in Shouguang City in 1997.Soil pH in the greenhouse showed a declining tendency as compared with that in the open field,while the content of organic matter a reverse one.The content of soil available nitrogen varied sharply from area to area,averaging 205 4 mg kg- 1,and the content of available P had a similar tendency and averaged 2252 mg kg^-1,showing an obvious build up effect and an extremely positive relationship with greenhouse age(r= 0.550^**,n= 35).The highest content of available K was up to 369.7 mg kg^-1,which also demonstrated an obvious build up effect.The older the greenhouse,the higher the content of available potassium(r=0.502^**,n=35).The content of soluble calcium was 337 9 mg kg^-1 in the surface soil,and the content of soluble magnesium was 67.8 mg kg^-1.Generally the content of soil trace elements,except boron,in the greenhouse was higher than in the open field,respectively.
