不同灌溉方式对槟榔生长、果实品质及产量的影响

Effects of Different Irrigation Methods on Growth,Fruit Quality and Yield of Arecanut

节水灌溉是实现槟榔产业可持续发展的重要途径。为筛选槟榔最佳的灌溉供水模式,通过田间试验,以无灌溉为对照(CK),设树盘漫灌(T1)和滴灌(T2)2种灌溉处理,探究不同灌溉方式对槟榔树体生长、果实品质及产量的影响。结果表明:不同灌溉方式对槟榔的生长,果实品质和产量都有一定的影响;与树盘漫灌和无灌溉相比,滴灌处理下槟榔植株形态指标最佳,其中叶面积分别增加10.13%和35.94%;可溶性糖含量、纤维素含量、可溶性蛋白含量最高;此外,滴灌处理下槟榔的产量最高,结果数为233.8个/株,产量高达5866.4 kg/hm^(2),增产效果最佳。因此,相比于其他灌溉方式,滴灌更适合槟榔的生产。

Water-saving irrigation is an important way to realize the sustainable development of arecanut(Areca catechu L.)industry.In order to select the best irrigation water supply mode for cultivation of arecanut,field experiments were conducted to investigate the effects of different irrigation methods,root zone flood irrigation and drip irrigation,on tree growth,fruit quality and yield of arecanut,with no irrigation as control.The results showed that different irrigation methods had certain effects on the growth,fruit quality and yield of arecanut.The arecanut plants under drip irrigation showed the best plant morphology indexes,of which the leaf area was increased by 10.13%and 35.94%as against that of the root zone flood irrigation and the control,respectively,and had the highest contents of soluble sugar,cellulose and soluble protein.In addition,the arecanut plants under drip irrigation yielded the highest,with 233.8 fruit per plant or 5866.4 kg·ha^(﹣1),indicating that the drip irrigation had the best effect on yield increase.Therefore,compared with the other two irrigation methods,drip irrigation is more suitable for arecanut production.
