摘要本试验研究了五种作物（羽扇豆、水稻、甘蓝、番茄、甜菜）在磷充足和缺磷营养液中的生长情况。以酸性磷酸酶为材料，研究了pH、高浓度K+、Mg 2+、Zn 2+、Cu 2+、Al 3+和土壤水浸液等环境条件对酸性磷酸酶活性的影响。水稻、甘蓝和甜菜的酸性磷酸酶活性在pH3.5 ~ 4.5范围内较高，随着pH的升高而降低，而羽扇豆和番茄的酸性磷酸酶活性在pH3.5 ~ 7.0范围内相对稳定。在大多数土壤的土壤溶液中，高浓度的K+、Mg 2+、Zn 2+和Cu 2+不会显着降低酸性磷酸酶活性，在0.4mM浓度下，Al ~（3+）对缺磷羽扇豆根系分泌的酸性磷酸酶活性有一定的抑制作用。从低磷土壤中获得的水提取物。
Abstract Five crops (lupin, rice, cabbage, tomato, sugar beet) were grown in phosphorus-sufficient and phosphorus-deficient nutrient solutions. Acid phosphatase was collected for 24 h, and the effects of several soil environmental conditions such as pH, high concentrations of K+, Mg2+, Zn2+, Cu2+, and Al3+, and soil-water extract on its activity were investigated. The activity of acid phosphatase was high at pH 3.5 to 4.5 and decreased with the increase of pH in rice, cabbage, and sugar beet, whereas the activity in the pH ranges from 3.5 to 7.0 was comparatively constant in lupin and tomato. The activity of acid phosphatase did not decrease significantly by high concentrations of K+, Mg2+, Zn2+, and Cu2+ in the ranges occurring in the soil solutions of most soils, but decreased slightly by Al3+ at the concentration of 0.4 mM. The activity of acid phosphatase secreted by the roots of phosphorus-deficient lupin decreased by the addition of the soil-water extract obtained from a soil with a low phosphorus c...
