香蕉半膜覆盖集成施肥技术效应

Integrated technology effect of film-half-covering and fertilization on banana

为解决香蕉地膜覆盖的科技含量不高,地膜覆盖新技术的应用比较单一等问题,形成集成的综合高产抗旱丰产体系,提高香蕉的高产潜力,在香蕉主产区做香蕉半膜覆盖集成长效肥、有机肥料、测土配方施肥技术田间试验研究。试验表明,香蕉半膜覆盖集成长效肥、测土配方施肥配套技术既固土保水、减少水土流失,又协调土壤的水分和养分,促进水肥互动,提高水肥利用效率;既减少了投入,又增加了作物产量和经济收入,具有推广应用价值。

In order to solve the problems of lower technical content and less application methods in banana surface field-coveting technology, to develop integrated high-yield and drought-resistance technical system and increase banana＇s high-yield potential, an field experiment and research were made in main banana pro- duction area for film-half-covering, long-effect fertilizer, organic fertilizer and soil-test-formulation fertilization. The experimental results show that this integrated water conservation, reducing soil erosion, harmonizing technology have the functions of soil fixation and soil nutrient and water, promoting water-fertilizer-in- teraction ad utilization efficiency, which can reduce input and also increase the economic income and yield, and is worth to be applied in production.
