| 摘 要： | 1998～2001年在海南东方干旱半干旱燥红土芒果与柱花草及作物间作示范区的实践表明，在芒果园间作扁豆、柱花草、番薯和花生可显著提高芒果挂果率，芒果收入比芒果单种分别增加97．79％、98．53％、54．41％和48．28％，果园综合收入比芒果单种分别增加108．55％、98．53％、97．98％和91．58％，同时，果园间作可显著提高果园土壤有机质、全氮、速效磷的含量和土壤pH值，间作扁豆使土壤有机质含量增加53．3％，间作柱花草使土壤全氮增加43．92％，速效磷增加78．16％，从而达到了以短养长、增加农民收入、提高土壤肥力和持续管理利用的目的。

| Abstract: | Intercropping with stylo and other crops in the semi-arid or dry red soil mango orchards of Hainan were practiced and demonstrated during 1998～2001, and the preliminary results show that field crops such as flat bean(Dolichos lablab), stylo(Stylosanthes spp.), sweet potato(Ipomoea batatus Lam.) and peanut(Arichis hypogaea Linn.) intercropped with mango trees would promote mango fruit growth and fruitsetting. The intercropped mango orchards produced 97.79%, 98.53%, 54.41% and 48.28% more fruit respectively than those that of not intercropped, and the farmer's overall income increased by 108.55%, 98.53%, 97.98% and 91.58% respectively. Meanwhile, the soil organic matter, total N, available P and soil pH in mango orchards also increased considerably. A mango orchard intercropping with flat bean had its soil organic matter increased by 53.3%, with stylo the soil total N increased by 43.92% and available P increased by 78.16%. Intercropping in mango orchards has improved the farmer income, the soil fertility and sustainable use of the land resources. |
