摘要
在定量施用氮、钾肥条件下,采用单因素田间试验方法研究不同施磷水平对香蕉产量与品质的影响。结果表明,在土壤速效磷含量适宜的香蕉园,株施尿素0.87 kg、氯化钾1.335 kg、有机肥2.0 kg、硫酸镁125.0 g、0.2%硼砂溶液喷1次,以施过磷酸钙1.165 kg/株,N:P_2O_5:K_2O=1:0.35:2(质量比),田间蕉株生长较快,假茎较粗,采收时功能叶片数较多,采收期较早且较短,产量较高;同时,果实外观和内质较好,果指较长较粗,淀粉和总糖含量,可食率略高、可滴定酸居中;经济效益最佳,净利润达3.96万元/hm^2,投入产出比为1:1.83。
The effects of different phosphate fertilizer application levels on banana yield and quality were studied in the same condition of nitrogen and potassium fertilizers application, using single factor field experiment method. The results showed that the banana plants in the fields grew faster with bigger pseudo-stems, longer and bigger fruit fingers, higher starch and total sugar contents and edible rate, moderate titratable acid, best economic benefit, a net profit of 2 637.6 yuan/hm2, and a input output ratio of 1 ： 1.83, when calcium superphosphate was applied at 1.165 kg/plant in the banana plantations with suitable available phosphorus in the soil, urea was applied at 0.87 kg/plant, potassium chloride at 1.335 kg/plant, organic fertilizer at 2.0 kg/plant, magnesium sulphate at 125.0 g/plant, 0.2% borax solution was sprayed one time.
