摘要
为研究控释肥对香蕉生产的影响,以桂蕉6号为材料,在广西南宁香蕉产区进行控释肥、常规肥比较试验。结果显示:在等价原则下,使用控释肥和常规肥蕉树最终株高分别为278.1 cm和286.5 cm,茎基围分别为79.1 cm和82.3 cm,差异均不显著;使用控释肥和常规肥在相同调查时间内抽蕾率分别为90.99%和91.26%,折合667m2产量分别为3692.92 kg和3760.68 kg,差异不显著;使用控释肥和常规肥香蕉果实果指长、穗长、穗粗等农艺性状差异不显著,其果实可溶性固形物分别为9.02%和9.13%,可溶性糖含量分别为16.58%和16.41%,总酸含量分别为3.11 g/kg和3.02g/kg,维生素C含量分别为9.42 mg/100g和9.51 mg/100 g,差异均不显著,但是,使用控释肥所需要的施肥次数和人工较施用常规肥少,从而减少劳动力的投入,降低生产成本,提高经济效益。
The compared test of release fertilizers(CRF) and general fertilizers(GF) was carried out to research the respect of CRF to banana; " Guijiao No.6" was toke to be material at Nanning, Guanxi province. The results showed that under the equivalence principle, the differences of the height of plant and the width of pseudo-stem base of two treatments were not significant, which used CRF reached 278.1 cm, 79.1 cm and the other one used GF reached 286.5 cm and 82.3 cm respectively. The difference of the bud rate and the yield at the same time were not significant, both reached about 91% and 3700 kg/667m2. The fruit length, spike length and spike diameter were no significant difference. The content of eatable rate, soluble solids, soluble sugar, total acid and Vitamin C of CRF treatment and GF treatment were similar, reached 9.02 %, 16.58 %, 3.11 g/kg, 9.42 mg/100 g and 9.13%, 16.41 %,3.02 g/kg, 9.51 mg/100 g respectively. Those were no significant difference but the ones used CRF need less fertilization times and less labor, and then can reduce labor inputs, reduce production costs and increase economic efficiency.
