摘要:

【目的】研究灰漠土长期不同施肥管理措施下,农田土壤全磷、有效磷(Olsen-P)的变化关系及对磷素盈亏的响应, 为科学施磷及土壤质量定向培育提供参考依据。【方法】以始于1989年的不同施肥措施的长期定位试验为研究对象,对土壤磷盈亏状况及土壤有效磷(Olsen-P)对土壤盈亏的响应关系、磷素活化系数(PAC)等进行分析。【结果】NP、PK、NPK、NPKS处理土壤PAC随施肥年限呈抛物线变化,并在第16年时达到峰值,NPKM、1.5NPKM处理PAC随施肥年限呈极显著线性正相关(P<0.01),年增加速率分别为0.23%和0.42%。CK、NK当季土壤表观磷盈亏呈现亏缺状态,当季土壤磷平均亏缺量分别为8.9、15.5 kg/hm2;NP、PK、NPK、NPKS当季土壤磷盈余值的平均值分别为35.4、38.9、32.3和25.4 kg/hm2,NPKM、1.5NPKM处理当季土壤磷盈余值分别为49.6、127.8 kg/hm2,年际盈余量随种植年限逐渐下降,施磷处理土壤有效磷增量与累计盈亏间存在显著相关性,每盈余100 kg/hm2磷,Olsen-P浓度可提高4.02 mg/kg。【结论】施肥方式和年限可显著影响灰漠土PAC和磷盈亏,施用有机肥可显著提高土壤PAC和土壤磷盈余;仅施化肥磷或化肥配施秸秆,土壤PAC和磷盈亏均存在峰值。

Abstract:

【Objective】 To investigate the relationship between soil total phosphorus and soil available phosphorus (Olsen-P) and the response to phosphorus budget, that under the long-term different manure management practices in grey desert soil, and investigate the transformation characteristics of phosphorus in grey desert soil, which provides a reference for the scientific application of phosphate fertilizer and oriented cultivation of soil quality. 【Methods】 Taking the long-term positioning experiment of different fertilizer management that started 1989 as the object to analyze the relationship between soil phosphorus activation coefficient (PAC), budget and soil available phosphorus (Olsen-P) response to soil budget. 【Results】 The PAC of soil treated with NP, PK, NPK and NPKS showed a parabolic change with fertilization years, and reached its peak value at the 16th year.The PAC of soil treated with NPKM and 1.5NPKM presented a very significant linear positive correlation with fertilization years (P<0.01), and the annual increase rate was 0.23% and 0.42%, respectively.CK and NK were deficient in soil apparent phosphorus in the current season, and the average phosphorus deficiency was 8.9and 15.5 kg/hm2, respectively.NP, PK, NPK, NPKS quarter average value of a surplus of soil phosphorus were 35.4, 38.9, 32.3 and 25.4 kg/hm2, NPKM, 1.5 NPKM treatment in the surplus value of soil phosphorus were 49.6, 127.8 kg/hm2, annual amount of surplus with the planting fixed number of year was falling, P processing increment and the total available P in soil was significant correlation between profit and loss, every surplus of 100 kg/hm2 phosphorus, Olsen-p concentration increased by 4.02 mg/kg. 【Conclusion】 Fertilization methods and years can significantly affect the PAC and P profit and loss of grey desert soil, and the application of organic fertilizer can significantly increase the PAC and P surplus of soil; There is peak value of PAC and p in soil when only fertilizer is applied or straw applied.

Key words: long-term fertilization; grey desert soil; soil available phosphorus; soil total phosphorus; phosphorus activation coefficient; phosphorus balance
