| 摘 要： | 进行了15种热带牧草在椰园间作的适应性试验,调查了它们的产量情况和生产参数并作统计分析。结果表明:在幼龄椰园内,间作豆科牧草和禾本科牧草,均可获得较高的经济产量;在光照强度大于30％的成龄椰园内,可间作多数禾本科牧草,并能获得一定的经济产量,但不宜间作豆科牧草;在光照强度低于30％的成龄椰园内,不宜于绝大多数牧草问作。间作于幼龄椰园的牧草产值可达1.0~3.0万元/hm2;间作于成龄椰园的禾本科牧草产值可达0.5～2.0万元/hm2。

| Abstract: | An experiment was conducted to study the survival rate, growth, flowering and yield of 15 species/ varieties of tropical grasses intercropped in young mature coconut plantations. The results showed that both gramineous and leguminous grasses were suitable for intercropping in young plantations with a good harvest. Most of gramineous grasses produced a reasonable income when intercropped in mature coconut plantations under the relative light intensity of over 30 % but the legumes failed to produce any income. However, most grasses did not grow well in the coconut plantations when the relative light intensity was under 30 % Generally, grasses intercropped in coconut plantations produced an income of RMB,000-30,000yuan/hm' in young coconut plantations and RMB5,000-20000 yuan/hm in mature plantations when suitable grasses were intercropped. |
