随着城乡人民生活水平的提高,农业经营方式的转变,城市垃圾,工业三废排放量的增加导致了有机肥源养分状况、积制方式和用量的变化,乃至污染物的掺入也影响了有机肥的品质。再者农村统一建设、生活条件和环境有了很大改善、一家一户散养畜禽大大减少。堆沤肥场也在缩小,对有机肥积制是个很大损失。农村责任制后,有机肥主要施用在蔬菜及瓜类上,大田作物只靠施用化肥,而很少或根本不施有机肥,这给农业生产带来了潜在的隐患。 一、有机肥的积制不容忽视 在有机肥的积制和使用方面。过去畜禽舍比较简陋,垫土比较方便,我们采取就地取土分层垫圈,在圈内堆积一定时间后出圈再堆一定时间、外围用
With the improvement of people’s living standards in urban and rural areas and the transformation of agricultural management modes, the increase of municipal solid waste and industrial wastes emissions has led to the changes in the nutrient status of organic manure sources, the mode of production and dosage, and even the incorporation of pollutants, The quality of fat. Furthermore, the unified construction of the countryside, living conditions and environment have been greatly improved, and the number of livestock and poultry to be rehoused at home has been greatly reduced. Heap 沤 fertilizer farm is also shrinking, organic fertilizer plot system is a big loss. After the responsibility system in rural areas, organic fertilizers are mainly applied to vegetables and melons, field fertilizers rely on only chemical fertilizers, and little or no organic fertilizers, which pose potential risks to agricultural production. First, the cumulative organic fertilizer system can not be ignored in organic fertilizer production and use. In the past, livestock and poultry houses were relatively simple and convenient for padding soil. We took local layered and layered gaskets to accumulate a certain time in the circle and then circled for a certain period of time. The periphery
