当前,随着化学肥料的大量使用,许多农户只知道尿素、碳铵等化学肥料的保管和使用,而忽视农村中最大肥源——农家肥的积肥、造肥工作,致使大量农家肥养分损失严重。现实生活中,有些农户的牲畜棚破旧漏雨,圈坑渗水漏肥:有些农民朋友将出栏粪往院内一堆就万事大吉,任其风吹、日晒、雨淋。这样粪尿中的氮素变成气体挥发了,可溶解的养分随水渗漏流失了,其结果是造成粪肥低劣。据测定,牲畜尿如果不及时垫土圈沤,单存半月,氮素损失可高达96%。因此,如何防止农家肥养分损失.应当引起农民朋友们的高度重视。
At present, with the extensive use of chemical fertilizers, many farmers only know the custody and use of chemical fertilizers such as urea and ammonium bicarbonate while neglecting the accumulated fertilizer and fertilizer making of the largest fertilizer source in the rural areas, resulting in the loss of a large amount of farmed fertilizer serious. In real life, some peasant households’ shacks leaking old and leaking, pit leakage seepage fertilizer: Some farmers friends will slaughter dung to the hospital a bunch of everything, let the wind, the sun, rain. In this way, the nitrogen in the excrement turns into a gas which evaporates. The dissolved nutrients are lost to the seepage of the water, resulting in poor manure. According to the determination of livestock urine, if not in a timely manner soil circle 单, save a single month, nitrogen loss can be as high as 96%. Therefore, how to prevent the loss of farmer’s nutrition should be caused by peasant friends attach great importance.
