中文摘要	研究了高寒半干旱区8年肥料定位试验中，磷肥和有机肥在莜麦上的产量效应、土壤磷素的平衡、土壤Olsen-P及各形态无机磷的变化。结果表明，单施磷肥（N0P1）莜麦增产30．8％、单施氮肥（N1P0）增产109．4％、氮肥和磷肥配合（N1P1）施用莜麦增产314．0％；NP间表现出显著正交互作用，NP（N1和P1）交互作用增产86．9％；施用22．5和45．0t／hm^2有机肥分别比N0P0处理增产115．1％和220．1％；施用有机肥基础上增施磷肥无明显增产效应。不同施肥处理土壤Olsen-P和各形态无机磷的增减取决于土壤磷索的积累与消耗量，7年不施磷肥土壤Olsen-P降低3．3mg／kg。施用磷肥和有机肥土壤各形态磷库均有不同程度的积累；土壤磷素积累以无机磷为主，其中Ca2-P和Ca8-P的积累量分别占土壤无机磷变化总量的19．3％和25．4％，Al-P和Fe-P分别占23．8％和14．8％，O-P和Ca10-P共占13．0％。依据土壤磷素收支平衡状况计算出维持土壤磷素平衡的P2O5用量为45．0kg／hm^2。根据肥料效应函数计算出有机肥用量为0、22．5t／hm^2时，P2O5的最高产量用量分别为98．4kg／hm^2和87．4kg／hm^2。
英文摘要	The yield responses of naked oats to phosphorus fertilizer and organic fertilizer, the balance between P input and output, and the changes in soil Olsen-P and inorganic phosphorus fraction pool were studied in 8-year experiments on chestnut soil at arid plateau region. The results showed that P fertilization in combination with N fertilizer could help raise naked oats yield, single application of P （N0P1） and N （N1P0） fertilizers brought about 30.8% and 109.4% of oats yield, respectively. Combined application of N and P fertilizers （N1 and P1） gave an increase of 314.0% compared with the control. There was an significant positive interaction effect of N and P fertilizers on yield which resulted in an increase of 86.9% of oats yield. Application of 22.5 t/ha and 45.0 t/ha of organic fertilizer alone gave an increase of 115.1% and 220.1% compared with N0P0, respectively, however, applying P fertilizer after the application of organic fertilizer did not show a yield-enhancing effect. The content of soil Olsen-P and inorganic phosphorus fractions were changed by applying P fertilizer and organic fertilizer on different treatments, The content of soil Olsen-P decreased by 3.3 mg/kg in no P fertilizer treatment after 7-years cropping. All phosphorus fraction pools addressed with P and organic fertilizers were enhanced at varying degreess. Most of residual P were inorganic phosphorus, among which Ca2-P and Ca8-P were accounted for 19.2% and 25.3%; Al-P and Fe-P were accounted for 23.4% and 15.3%, respectively; and O-P and Ca10-P were accounted for 13.5% of total inorganic P. According to the balance between P input and output, 45.0 kg/ha was figured out as the critical rate of P2O5 that could maintain the P balance in soft. The recommended application rates of P fertilizer for maximum yield combined with 0 or 22.5 t/ha organic fertilizer using regression equations were 98.4 kg/ha, 87.4 kg/ha respectively.
