不同滴灌施肥方式对海南香蕉生长和产量的影响

通过大田小区试验，研究等肥量条件下不同滴灌施肥方式中香蕉的生长效应，以期为海南干热种植区香蕉灌溉和施肥提供技术支持。试验共设3种灌溉施肥方式，依次为喷水带(CK)、单管滴灌(DF1)、双管滴灌(DF2)。试验结果表明：DF1、DF2处理在香蕉周年生长中的灌水量分别为CK处理的51.5%、59.2%，产量比CK处理显著增加，增产率分别为9.6%、11.5%。综合经济效益分析，DF2处理因更高的产量而获得最佳纯收益。

Effect of Different Drip Fertigation Methods on Growth and Yield of Banana in Hainan Province

A field experiment of two drip fertigation methods（single lateral and double laterals per plant, abbreviated as DF1 and DF2）and sprinkling tape fertigation (CK) as on growth and yield of banana in Hainan province was conducted to offer a technological support for banana irrigation and fertilization. The results indicated that, as compared with sprinkling tape fertigation, the total irrigation amount of drip fertigation with single and double laterals during the whole banana growth period was only 51.5% and 59.2%, respectively. And the yield was increased by 9.6% and 11.5%, respectively. However, as compared with CK and DF1 treatment, the net benefit of fruit production was increased by DF2 treatment due to higher yield.
