摘　　要：针对连作4年的海南乐东黎族自治区尖峰镇的菠萝地块,将生防菌(枯草芽孢杆菌HL2)、载体(菜籽饼、泥炭土、椰糠)和普通有机肥(OF)利用二次发酵技术制成生物有机肥(BOF1、BOF2、BOF3),以单施化肥为对照(CK),通过田间试验,研究不同生物有机肥与无机肥配施对菠萝连作土壤养分、产量和经济效益的影响。结果表明,在菠萝整个生育期,与CK相比,普通有机肥(OF)处理和生物有机肥(BOF1、BOF2、BOF3)处理均能提高连作菠萝土壤pH、有机质、速效磷含量、菠萝产量和经济效益,分别提高26.99%~67.41%、13.65%~150.32%、4.96%~70.9%、31.21%~66.83%、25.31%~55.88%;与CK相比,施用生物有机肥BOF1能提高连作菠萝土壤的速效钾含量,为9.04%~37.38%。施用OF和生物有机肥与无机肥配施均能改善土壤养分状况、提高菠萝产量、增加经济效益,特别是生物有机肥BOF1效果更优。通过产量数据与土壤养分指标评价指数进行回归分析,结果表明,菠萝产量与土壤养分具有一定的相关性。Pineapples in the plantation under long-term continuous cropping were applied with organic or biological organic fertilizers(OF,BOF1,BOF2,BOF3)prepared from bacteria(Bacillus subtilis HL2)as a biocontrol agent,carriers(rapeseed cake,peat soil,coconut bran)and common organic fertilizer by secondary fermentation technology,and chemical fertilizer as control(CK)to analyze the effects of the organic,bio-organic and inorganic fertilizers on soil nutrients,yield and economic benefits of the pineapple plantation under continuous cropping.In the whole growth period of pineapple,the treatments with organic and bio-organic fertilizers increased the soil pH,the soil contents of organic matter and available phosphorus,and yield and economic benefit of pineapples in the pineapple plantation under continuous cropping by 26.99%~67.41%,13.65%~150.32%,4.96%~70.9%and 31.21%~66.83%,25.31%~55.88%,respectively as compared with CK.The BOF1 treatment increased the content of soil available potassium in the pineapple plantation under continuous cropping by 9.04%to 37.38%.Organic fertilizer(OF),bio-organic fertilizers(BOF1,BOF2,BOF3)and inorganic fertilizer all improved soil nutrient content,and increased pineapple yield and economic benefits,especially the bio-organic fertilizer BOF1 which was much better than other fertilizers.Regression analysis of yield data and evaluation indexes of soil physical and chemical indicators showed that pineapple yield has a certain correlation with soil nutrients.
