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。
Nut hybrid Mongolian wow, first introduced in 1979 in Hainan Island. After nine years of site-planted observation, the results showed that: (1) horsewow grew faster than Hainan high-variety (control), put into production early and had high yield. (2) There was no significant difference in the reproductive habits and the main nutrition of fruits (copra, fat, protein, etc.) and the disease resistance and insect resistance of Horseshoe. ③ Ma Wow species of bad traits are: fruit is too small, leaves a large distance, the trunk pull too fast, the underlying old leaves decline too early. At the same time, leaves soft and crisp, wind resistance less. Despite being slightly wind-resistant and cold (juvenile), the horsewill is slightly more capable than Hainan’s, but even in Wenchang County, one of the worst-hit and low-temperature areas in northern Hainan Island, high yields are still achieved, Hainan high species 50%, or even more than 1 times, so the higher economic benefits. Mawa species can be planted in the existing high-coconut palm area of Hainan Island, while planting more in the areas along the southeast coast of Wanning, Lingshui, Sanya and Ledong can better demonstrate their high-yielding characteristics. The proposal focuses on popularizing horse wow species in this area.
