简介:近几年来,国内出现了大多数农产品供过于求,价格低迷,农民收入增长迟缓,农业产业结构层次低,结构趋同等于不正常扭曲现象。针对这一现象,我市农调队深入农村进行了实地调研,结果发现造成这一状况有以下原因:一是农民在农业结构调整中盲目性很大,从众心理强。别人种什么,他就跟着种什么,以致农畜产品多次出现了更多,少了更少的问题。如:九十年代初期果品价格很好,农民纷纷弃粮改果,扩种果树,结果,还没到盛果期,果品价格就直线下跌,生产的鸭梨仅几块钱一大筐,无线可赚,纷纷伐掉,损失极大。二是过分强调自然优势,不注重品种和品质的提高。有的地方政府强调农民种什么,不种什么,不注重市场需求,销售渠道不畅,以致自然特色和传统名牌优势不强。三是大部分农民自认为什么赚钱种什么,只盯着眼前的行情,不看市场的变化。
