摘要
在水肥耦合微喷灌溉仅为微喷灌溉后撒肥或传统人工淋灌撒肥处理的70%施肥量条件下,研究水肥耦合微喷灌溉对香蕉生长和产量的影响。结果表明:水肥耦合微喷灌溉可减少香蕉施肥量30%以上;较传统人工淋灌撒肥,在香蕉营养生长盛期和生殖生长期缺水干旱的雷州半岛,缩短香蕉生育期24.9 d,增加产量17.6%,在香蕉生殖生长期缺水干旱的珠江三角洲,缩短香蕉生育期12.3 d,增加产量12.1%。
Effects of Micro-spray irrigation coupling with water and fertilizer on banana growth and production were studied on the condition with 70% of the fertilizer that was used after micro-spray irrigation and traditional artificial irrigation. The results show that more than 30% of the volume of fertilization was reduced with micro-spray irrigation coupling with water and fertilizer. In the Leizhou Peninsula in Xuwen County with a drought vegetative and reproductive growth stage in banana planting, Micro-spray irrigation coupling with water and fertilizer the growth period shorten 24. 9 d, and the yield increase 17.6 % than traditional artificial irrigation. In Boluo county in the Pearl River Delta with a drought reproductive growth stage, the growth period was shortened 12.3 d, and the production was increased 12.1% than traditional artificial irrigation.
