摘　　要：为了研究控释掺混肥与土壤调理剂配施在滨海盐碱地上施用对作物生长及盐碱土化学性质的影响,本试验利用渤海盐碱地大田试验,与农民习惯施肥进行对比,根据当地土壤养分含量情况,研究了控释掺混肥配施腐植酸调理剂和生物有机肥对轻度盐化滨海盐碱土夏玉米栽培上的土壤性质作物产量及经济效益等方面的影响。结果表明,控释掺混肥、腐植酸缓控释肥、控释掺混肥配施腐植酸调理剂配施、控释掺混肥配施微生物有机肥相比农民习惯施肥不同程度降低滨海盐碱地土壤pH值;各处理比农民习惯施肥处理土壤含盐量有所增加,但大多差异不显著;控释掺混肥比农民习惯施肥处理在玉米生育期大部分提高了土壤硝态氮(NO_3^-)与铵态氮(NH_4^+)含量,最高增幅分别为14.5%和16.1%;控释掺混肥配施腐植酸调理剂处理玉米千粒重最高,为353.2 g,与农民习惯施肥处理差异达显著水平;玉米产量和纯收入以控释掺混肥处理最高,产量达8832 kg/hm^2,比农民习惯施肥处理增产15.23%,纯收入增加2578元/hm^2,均达显著水平。综合考虑,在低含盐量滨海盐碱土种植玉米,建议施用控释掺混肥。In order to research the effect of controlled release blended fertilizer with soil conditioner on the growth of crops in coastal saline area, the experiment was conducted in the field experiment of saline land in Bohai Sea was compared with farmer conventional fertilization, according to the local soil nutrient content, to research the effects of controlled-release blended fertilizer, humic acid conditioner and bioorganic fertilizer on the soil pH, soil properties, crop yield and economic benefit. The results showed that controlled-release blended fertilizer, humic acid slow-release fertilizer, controlled-release blended fertilizer with humic acid conditioner, and controlled-release blended fertilizer with microbial organic fertilizer compared with conventional fertilization reduce the soil pH of saline soil in coastal area; other four treatments compared with the farmer conventional fertilization, the soil salinity was increased, but most of the differences were insignificant; compared with the conventional fertilization treatment, controlled release blended fertilizer increased the content of soil nitrate nitrogen and ammonium nitrogen, the highest increase was 14.5% and 16.1%; the highest 1000-grain weight value among the treatments was controlled-release blended fertilizer with humic acid conditioner, which was 353.2g, which was significantly different from the conventional fertilization treatment; among all of the treatments, the highest yield of maize and net income were the controlled release blended fertilizer treatment, which were 8832 kg?hm-2 and 2578 yuan per hectare, all reached the significant lecel; compared with the farmer conventional fertilization, the yield increased 15.32%. Taking into account, in the low salinity coastal saline soil planting corn, it is recommended to use controlled-release blended fertilizer.
