印度的绿色革命正处在失败的边缘。这个国家正在失去它的土壤。环境保护部门的官员们说,每年流入河里的表层土壤为120亿吨(原文如此—编者)。自1950年以来,政府耗资120亿卢比(10亿美元),采用了许多方法来抑制这种趋势,但收效甚微。现在,一些官员已经认识到,有一种简单的花钱少的潜在办法——它就是土生土长在印度的香根草(Khus). 印度农业产出引入注目的增长(特别是小麦产量为60年代中期的3倍),主要来自灌溉地区,例如旁遮普等地。那里土地平坦,渠岸坚固,通常不致塌陷或堵塞,不存在土壤侵蚀的问题。但在旱作地
India’s green revolution is on the brink of failure. This country is losing its soil. Officials from the environmental protection department said that the annual amount of surface soil flowing into the river is 12 billion tons. Since 1950, the government has spent 12 billion rupees (one billion U.S. dollars) and has taken many measures to curb this trend, with little success. Now, some officials have come to realize that there is a simple potential to spend less - a native of India, where the remarkable growth of agricultural output in India (notably wheat production in the mid-1960s 3 times), mainly from irrigated areas such as Punjab. There the land is flat and the crevasse is strong, usually without collapse or blockage, without soil erosion. But in dry land
