Abstract: Phosphorus and potassium morphology, content and accumulation characteristic of greenhouse were studied to distinguish the present situation of successive and excessive fertilization in greenhouse, using the means of comparison sampling in greenhouse, open vegetable field and grain -cotton field. The results showed that both phosphorus and potass- i um content had obviously accumulation in the 0- 25 and 25- 50 cm layers of greenhouse, and the accumulation of phos - phorus was higher than that of potassium, and the accumulation was higher and higher with protected cultivation age of greenhouse.Recent years the potassium accumulation in soil had the quickening tendency.The study on different morpho- l ogy and content of inorganic phosphorus showed that the proportion of Ca2 -P, Ca 8 -P in greenhouse was higher than that in open vegetable field and in grain -cotton field, and that in open vegetable field preceded that in grain - cotton field.The same tendency was found in slow available potassium content?Those showed that the accumulation phosphorus and potas -sium still had high validity.
