本文报道了与甜荚树行道式耕作有关的两个试验。对从哥斯达黎加收集到的甜美树种质的早期生势和死覆盖产量的评价表明,种质的这两个特性都具有明显的差异。在4次收获中,4个产量最高的种质,死覆盖产量比伊巴丹本地种的高37％,用实生苗建立6种种植密度,以测定它们对甜荚树死覆盖产量的影响。在4次收获中,每米约种10株苗的死覆盖产量最高。

This paper reports two experiments related to the pod cultivation of sweet pods. An evaluation of the early and dead overgrowths of sweet tree germplasm collected from Costa Rica shows that there are significant differences between the two traits of germplasm. Of the four harvestings, the four highest-yielding germplasm, dead-covered, were 37% more productive than native Ibadan, and six seedlings were planted with seedlings to determine their effect on the dead-covered yield of the sweet pod. In four harvests, the dead-crop yield of about 10 seedlings per meter was the highest.
