- 摘要:
- 在云南省永胜县金沙江干热河谷地区种植木豆，研究了种植木豆对土壤肥力的影响，结果表明：木豆耐旱、耐瘠，出苗后在较干旱情况下也可以正常生长，而且对土壤酸碱度有较广的适应性，作为先锋植物可在金沙江干热河谷生态恢复中发挥重要作用；种植木豆后的土壤全氮、碱解氮都有较大增加，表明种植木豆可以起到固氮、培肥地力的作用；同时使土壤中全磷含量降低，而有效磷含量增加，说明木豆根释放的有机酸可分解土壤中的固态磷为速效磷，提高磷的利用效率。
- Abstract:
- In this research,the effects of cultivating pigeonpea on restoration of ecology and soil nutrient were investigated in arid hot valley of Jinsha River,Yongsheng county of Yunnan province.The results showed that pigeonpea could tolerate arid intimidation and acclimated various alkalinity and acidities soil after seeding in arid areas,pigeonpea therefore was considered an important pioneer species of restorating ecology.Total nitrogeon and available nitrogeon content increased with pigeonpea growing in the soil,which indicate that pigeonpea can fixate nitrogen and enhance soil fertility.Total phosphorus content decreased after seeded,but available phosphorus content increased,the reason is that the roots exuded organ acid,which can decompound solid phosphorus into available phosphorus.
