加强现有肥料的保管工作,减少养分流失,提高肥料质量,是农村积肥、造肥应该特别注意的问题。根据我们调查,在积肥、造肥工作中,肥分损失严重、积肥质量低劣的现象,在农村中较为普遍。为此,我们提出以下几条具体保肥办法,供各地参考。一、减少家畜粪尿养分流失的办法牛、驴、骡、马、猪、羊等家畜的粪尿是优质农家肥。家畜的粪与尿性质不同,所含成分也不同。粪中的氮素主要是蛋白质态氮,分解缓慢,作物难以吸收;尿中的氮素呈尿素、尿酸、马尿酸等水溶性有机态,易转化成植物易吸收的氨 Strengthening existing custody of fertilizers to reduce nutrient loss and improve fertilizer quality, rural fertilizer, fertilizer should pay special attention to the issue. According to our survey, in the plot fertilizer, fattening work, fat loss serious, poor quality of fertilizer, the phenomenon is more common in rural areas. To this end, we propose the following specific ways to save fat for reference. First, reduce the loss of livestock manure Nutrient cattle, donkeys, mules, horses, pigs, sheep and other livestock excreta is a high-quality farm fat. Livestock’s fecal and urine properties are different, contains different ingredients. Stool nitrogen is mainly protein nitrogen, slow decomposition, the crop is difficult to absorb; urine urea urea, uric acid, hippurate and other water-soluble organic state, easily converted into plant ammonia easily absorbed
