1994～1997年山东寿光设施蔬菜年平均施肥量达到N 1351.2kg hm-2、P2O5 1701.2kg hm-2和K2O 539.6kg hm-2;2004年与1997年相比,氮肥和磷肥的用量减少,钾肥的用量增加,有机养分的比例增加。日光温室蔬菜氮肥、磷肥、钾肥的表观利用率分别为21.33%、2.82%、61.34%。蔬菜土壤有机质含量高于露地土壤。寿光日光温室土壤中碱解氮含量平均205.4mg kg-1;速效磷的含量平均为225.2mg kg-1,具有明显的积累效应,与设施种植时间之间存在极显著的相关性(r=0.550**,n=35);土壤速效钾含量最高为369.7mg kg-1,也具有明显的积累效应,与设施使用时间具有极显著的相关性(r=0.502**,n=35)。设施表层土壤中水溶性钙的含量平均为336.0mg kg-1,土壤水溶性镁的含量平均为70.6mg kg-1。日光温室土壤中微量元素除硼外,含量均高于露地土壤。地下水硝酸盐污染严重,而且上升迅速。
The annual average fertilization rate of vegetables in Shouguang facility in Shandong Province from 1994 to 1997 reached N 1351.2kg hm-2, P2O5 1701.2kg hm-2 and K2O 539.6kg hm-2. Compared with 1997, the amount of nitrogen and phosphate fertilizer decreased, Increase in the amount of organic nutrients increased. Apparent utilization rates of nitrogen, phosphorus and potassium in vegetable in sunlight greenhouse were 21.33%, 2.82% and 61.34% respectively. Vegetable soil organic matter content is higher than the open soil. The average content of available nitrogen in soils was 205.4 mg kg-1 in Shouguang greenhouse. The average content of available phosphorus was 225.2 mg kg-1, which showed a significant accumulation effect and significant correlation with planting time (r = 0.550 **, n = 35). The highest content of available potassium in soil was 369.7 mg kg-1, which also had a significant accumulation effect and had a very significant correlation with the service life (r = 0.502 **, n = 35). The average amount of water-soluble calcium in the surface soil of the facility was 336.0 mg kg-1, and the average content of soil water-soluble magnesium was 70.6 mg kg-1. The content of trace elements in soils of sunlight greenhouse except boron was higher than that of open soil. Groundwater nitrate pollution is serious, and rising rapidly.
