近年来,许多农民怕用工,怕费事,种田不愿施农家肥,而是愈来愈依赖化肥。据调查,目前我国一些地方80%以上的农田长期不施用农家肥。俗话说:“庄稼一枝花,全靠粪当家”,“种地不上粪,等于瞎胡混”。农家肥含有丰富的有机物质,除氮、磷、钾之外,还有铁、锰、镁、硼等微量元素。它 In recent years, many peasants are afraid of using their labor and are afraid of trouble and farming. They are reluctant to apply peasant manure and instead rely more and more on fertilizers. According to the survey, at present, more than 80% of farmland in some parts of China do not apply farmyard manure for a long time. As the saying goes: “a crop of flowers, thanks to manure”, “not on the manure, is equal to blind mix.” Manure is rich in organic matter, in addition to nitrogen, phosphorus and potassium, there are iron, manganese, magnesium, boron and other trace elements. it
