这片大米种植基地化肥使用量年均减少一大半以上,优质水稻亩均产550公斤,农残余量检测全部为零,土壤有机质含量显著提高,遏制了农业面源污染的扩散。在安徽省合肥市肥西县西南部的柿树岗乡,有座占地面积在合肥数一数二高达7500亩的生态农庄。庄园内瓜果鱼虾、苗木花卉一应俱全,苗木果蔬一律人工拔草,每年耗资30万元租用无人机喷洒高效低残的生物农药统防统治。更奇怪的是,农庄主人对园内3年蔚然成林进入丰产
The use of chemical fertilizers in this rice planting base has decreased by more than half annually, and 550 mu of high-yield rice has been produced.
