The expert added that the continuing decline of grain prices since September may also hurt farmers' income this year despite the government's vow to increase thecrops' minimum purchase prices.
Minimum price就是“最低价格”。Minimum还可以单独做名词表示“最低点”。They want to spend a minimum of both time and money.(他们想花费最少的时间和钱)。除了crop’s minimum purchase price,还有minimum wage guarantee system(最低工资保障制度)、the minimum living standard security system(最低生活保障制度),以及minimum charge(最低消费)。
