对海南三亚、陵水地区滨海河岸砂土成龄间作椰园的调研结果表明,该地椰园行间相对光强度为34.03～61.09％;0～30厘米土层椰子根系稀少;每亩椰园的水平有效根区仅占15～20％,椰园间作后生态条件得到改善,土壤肥力提高,不仅增加了间作物的收益,而且椰子平均单株和每亩果实产量提高22.5～133.6％,果实的品质也有所提高,从而大大提高了椰园单位面积的经济效益。本文还提出该地区椰园间作的要求和结构模式。
The results of the research on the coconut garden of sandy soil in the coastal banks of Sanya and Lingshui areas in Hainan showed that the relative light intensity of the coconut trees in the area was 34.03 ~ 61.09%; the coconut roots in 0 ~ 30 cm soil layers were sparse; The effective root area only accounts for 15-20%. After the coconut garden intercropping, the ecological conditions are improved and the soil fertility is improved, which not only increases the income of the intercrop crops, but also raises the yield of fruit and fruit per plant and fruit by 22.5-133.6% The quality has also been increased, thus greatly improving the economic benefits of coconut garden unit area. The paper also proposes the requirements and structure model of coconut garden in this area.
