摘要：在中国云南省怒江流域设计井营造木豆与不同树种的混交生态林，每年木豆结荚期样地调查各树种的生长量（株高、地径、冠幅、一级分枝等）、木豆产量（每株结荚数、产种量等）、植被变化情况、土壤剖面（造林2年後进行，并设对照剖面）。植株生长量及木豆干籽粒产量测定结果表明，在所测试的生态林模式中，木豆（ICP7035）／马鹿花模式最好。土壤养分含量化验结果表明，木豆生态林封维持和改善土壤肥力有较好效果。土壤剖面观测结果表明．木豆生态林对改良土壤结构和增加土壤有机质含量作用显着。林份调查结果表明，木豆生态林可以很好保护项目区域内原始植被的生物多样性。
Pigeonpea based agroforestry models were designed and tested in Nujiang river valley slopes in Yunnan province of China. The growth increment parameters （plant height, stem diameter, plant canopy, number of primary branches, etc.） of different plant components in the tested agroforestry systems, yield components of pigeonpea （pods per plant, dry seed yield, etc.）, ingredients of vegetation in the tested plots, soil nutrition and soil profiles constitution were examined during pigeonpea podding stage each year in the tested agroforestry systems. Based on the test results of growth increment, pigeonpea （ICP 7035）/Pueraria wallichii DC agroforestry model was the superior agroforestry system in all tested agroforestry systems. According to the soil nutritional tests, pigeonpea based agroforestry was the maintainer and improver for soil fertility. Results from soil profile examination revealed pigeonpea based agroforestry an improver for soil structure and for soil organic matter content. Vegetation ingredients examination results testified that the pigeonpea based agroforestry can well conserve the biodiversity of original vegetation in the project area.
