印度热带作物研究所的科学家们最近发现,豆科植物中的木豆和鹰嘴豆的根部能自动固磷。热带地区土壤中多余的铁或钙与磷结合在一起,使作物不能从土壤中吸收到足够的磷,因而热带地区常常不得不多施磷肥。印度科学家们在观察和实验中发现,是否施磷肥对一般作物影响颇大,但唯有木豆和鹰嘴豆除外——不论施不施磷肥,也不论施多少磷肥,他们的产量都相差不太。科学
Scientists at the Indian Institute of Tropical Crops recently discovered that the roots of legumes and chickpeas in the legumes autogenously fix phosphorus. In the tropics, excess iron or calcium in the soil is combined with phosphorus, so that crops can not absorb enough phosphorus from the soil that the tropics often have to fertilize them. Indian scientists observed and experimentally found that whether phosphate fertilizer has a significant effect on the general crop, but only the addition of pigeons and chickpeas - regardless of the application of phosphate fertilizer, regardless of the amount of application of phosphate fertilizer, their production is not the difference too. science
