摘要
为探明胡椒园间作槟榔的优势,并筛选出适宜种植密度,对比了单作与间作以及不同间作种植密度之间的产量及纯收入.结果表明,胡椒园间作槟榔具有明显产量优势,平均间作优势达2 466 kg/hm2,土地利用率平均提高78％;间作体系优势主要来自胡椒;间作体系中槟榔密度对间作优势具有显著影响;常规种植密度胡椒园间作槟榔以833～1 000株/hm2为宜,其中槟榔密度为833株/hm2时效益最高.
To determine advantages of the intercropping system of areca with black pepper and the suitable planting density, yield and net income were contrasted between the monocuhure and intercropping, and among different intercmpping densities. The results showed that the intercmpping system had obvious yield advantage, about 2 466 kg/hm2 on average, and the land utilization increased by 78% averagely. The intercropping advantage mainly came from black pepper. The areca density had a significant influence on intercropping advantage. The appropriate intercropping density of areca was 833-1 000 plants/hm2, and the benefit was the highest with 833 plants/hm2.
