摘要
海南为我国栽培香蕉的主产区之一,西南部干热地区(昌江、东方、乐东、三亚)是海南省目前发展香蕉规模最大的区域,也是中国规模化反季节香蕉生产的主要基地之一。由于位处干热气候影响下的半干燥区,干旱较严重,加上施肥欠合理,对香蕉产业的可持续发展影响极大。发展节水灌溉是解决海南干热地区干旱缺水的必由之路,应用水肥一体化技术对香蕉实施节水灌溉,根据作物需要进行施肥,在保证香蕉的产量和质量的前提下,实现节水、省肥、节省人工之效,从而达到产业增效目的。
Due to the arid climate,unequal seasonal distribution of water resource and non-scientific fertilizer application,the banana industrial development in xerothermic area in Southwest Hainan province is strongly constricted.Water and nutrient are the two key factors in the growth of banana.The development of water-saving irrigation is the only way to resolve drought in xerothermic area in Southwest Hainan province.Integration of water into fertilizer has lots of special advantages in irrigation-agriculture since it provides the most effective way of supplying nutrients to the plant roots.Integration of water into fertilizer is advantageous to save the cost of water,fertilizer and labor,and there are more economic benefits in integration of water into fertilizer.
