摘要 香蕉栽培管理水平是决定香蕉产量和效益高低的重要因素。不同耕作措施对蕉园土壤理化性质、香蕉产量及生产投入的成本存在差异。2013~2014年间,通过几种耕作栽培方式(农户习惯管理、深耕、免耕及免耕覆秸秆)应用,研究其对香蕉产量及经济效益的影响。结果表明:拟定计划目标产量48 t/hm2,分别确定N、 P2O5、K2O施用量为540、90、1630 kg/hm2,免耕覆秸秆处理在营养生长期、花芽分化期、抽蕾期与采收期,其株高、茎围及青叶数等生长性状指标表现较大的优势;抽蕾率及经济效益分别为41%和3.28万元/hm2,与对照处理差异达到显著水平。 This study was conducted to investigate the effects of tillage modes on yield of banana and economic benefit. There are differences of costs in different tillage measures on soil physical and chemical properties, yield of banana and production input. This test in 2013~2014, There are four ways to the farming cultivation of habitual manage, deep cultivation, zero tillage and minimum tillage straw, respectively. Test results show: The proposed target yield 48 t/hm2, applying points to determine the N, P2O5, K2O content was 540, 90, 1 630 kg/hm2. Use to no-tillage with straw processing in vegetative period, bud differentiation stage, bud stage and the harvest time for the plant height, stem circumference is advantage. The treatment (zero tillage with straw, NS) processing of grow bud rate and planting benefit distribution of 41%and 32 781.8 yuan/hm2. The effect of NS on CK treatment reached a significant level.
