The study of nutrient balance of nitrogen, phosphorus and potassium of three river plain, Heilongjiang albic rice soils. The study indicated that, each experimental region has a high rate of increase production, the balance could had some surplus, shouldn’t had any deficit. But in order to protect the fertilizer supply ability of soil and environment, the nitrogen surplus of each experimental region should be controlled. The phosphorus should care to a balance or has a few deficit. The potassium could had some surplus. The phosphorus and potassium should keep balance. We can see from the valuation of nutrient balance that the nutrient of revenue and expenditure of each region was nitrogen and phosphorus were surplus, potassium was deficit. The practical rate of gain and loss of nitrogen, phosphorus and potassium were all in the permit range, this indicated that exploit of nitrogen, phosphorus and potassium are rather reasonable. The nutrient of albic rice soil had a great change as the high supply level of nitrogen and phosphorus and low supply level of potassium, this kind of soil now isn’t lack of nitrogen, the phosphorus is surplus and is short of potassium, but it was lack of nitrogen and phosphorus and rich of potassium before. In a word, the chief question is to solve the balance of nitrogen phosphorus and potassium if the production of three river plain, Heilongjiang province albic rice soil need continue development. The solution is to increase the potassium supply, decrease the phosphorus supply appropriately while controlling the nitrogen supply. The negative effect on environment and the efficiency of using fertilizer should be considered during the production which means that the permanent use of resource and protecting environment should be took in consideration which considering increasing the yield.
