摘　　要：为了研究控释掺混肥与土壤调理剂和生物有机肥配施对种植小麦的轻度盐化的滨海盐碱地的土壤性质、作物产量及经济效益方面的影响,利用滨海盐碱地进行小麦大田试验,并与农民习惯施肥进行对比。试验结果表明:在20~40 cm土壤中,与CCF处理相比,CRF处理可降低土壤全盐量6.6%~13.2%;相比CCF处理,CRF处理在小麦各个时期增加了耕层土壤的硝态氮含量,增幅为2.9%~13.1%,差异显著;CRF处理的小麦千粒重和产量均为最高,分别为37.45 g和5 963 kg/hm^2,较CCF处理差异显著,产量较CCF处理增加15.4%;CRF处理较CCF处理增加纯收入1 682元/hm^2,差异显著。从施肥便捷性、小麦产量和纯收入考虑,在低含盐量的滨海盐碱地种植小麦,推荐施用控释掺混肥。In order to study the effects of combined application of controlled-release bulk blended fertilizer with soil conditioner and bio-organic fertilizer to the light salinized soil in coastal saline area for growing wheat on soil properties, crop yield and economic benefit, a wheat field experiment in coastal saline area is carried out and is compared with farmer conventional fertilization. Experimental results show that in the 20 -40 cm soil layer, compared with the CCF treatment, the CRF treatment reduces the soil total salt content by 6.6% - 13.2% ; compared with the CCF treatment, the CRF treatment increases NO3-- N content in surface soil at different growth stages of wheat, with increase range of 2.9%-13.1%, the difference is significant; thousand kernel weight and yield of CRF treatment wheat are the highest, being 37.45 g and 5 963 kg/hm2 respectively, compared with CCF treatment, the difference is significant, the yield increases by 15.4% than that of CCF treatment; CRF treatment increases net income by 1 682 yuan/hm2 than that of CCF treatment, the difference is significant. From perspective of convenience of applying fertilizer, wheat yield and net income, the application of controlled-release bulk blended fertilizer is recommend for growing wheat in the light salinized soil in coastal saline area.
