摘要
榔子杂交种马哇,于1979年首次引进海南岛。经9年布点试种观察,结果表明:①马哇种比海南高种(对照)生长快,投产早,产量高。②马哇种的生育习性和果实主要营养(椰干、脂肪、蛋白质等)含量以及抗病、虫能力与海南高种无显著差异。③马哇种的不良性状有:果实偏小,叶痕距大,树干拔高太快,底层老叶衰落过早。同时,叶软而脆,抗风能力较次。尽管马哇种抗风、寒(幼龄期)能力比海南高种略次,但即使是在海南岛北部重风害和低温区之一的文昌县种植,仍能获得高产,其产量仍比海南高种高50%,甚至1倍以上,因此经济效益较高。马哇种可在海南岛已有的高种椰区种植,而在东南沿海的万宁、陵水、三亚和乐东一带种植更能表现其高产特性。建议重点在这一地区推广种植马哇种。
MAWA,a coconut hybrid was first introduced into Hainan in 1979.The results of
trial planting in different locations over a period of nine years showed that MAWA
was superior to Hainan Tall(control)in growth rate,unproductive phase and yield,
while similar with the latter in breeding habit,major nutrient contents(copra,
fat,protein,et al.)of nuts and diseases and pests resistance.However,MAWA had
some undesirable characters,such as smaller nuts,larger span of leaf scar,excess-
ive elongation of stem and earlier senescence and falling of lower leaves.Besides,
its soft and brittle lamina rended it poorer wind tolerance.Although it was some
what inferior to Hainan Tall in wind and cold(juvenile stage)resistance,MAWA
contributed higher yield,50% or even 100% higher than the latter even though in
the wind—prone and colder areas,such as Wenchang County in north Hainan.It is
thus suggested that MAWA can he grown in any of the existing Hainan Tall area,
in particular in the southeastern coastal counties,Wanning,Lingshui,Sanya and
Ledong,where it can display fully its high yield potentials.
