建国以来,我省化肥生产发展很快,用量不断增加,对农业增产保收起了重要作用。据1982年统计资料,全省化肥施用量为373万吨,每亩平均约75斤。但是化肥的分配极不均匀,高者超过200斤,低者仅几斤,而且氮、磷肥比例也很不协调。全省平均氮磷比例为1:0.23,个别地区仅为1:0.001,甚至不施磷肥。目前,随着化肥施用量的不断增加,分配量和施用比例不合理的现象也越发明显。尤其是农村实行生产责任制以后.不少农户又出现了盲目多施化肥(主要是氮肥)的倾向,致使肥效和经
Since the founding of the People’s Republic of China, fertilizer production in our province has been developing rapidly with an increasing amount of inputs, which has played an important role in increasing agricultural output and ensuring income. According to 1982 statistics, the province’s fertilizer application volume of 3.73 million tons, an average of about 75 pounds per mu. However, the distribution of fertilizers is very uneven, the highest over 200 pounds, the lower is only a few pounds, but also the proportion of nitrogen and phosphorus are also very uncoordinated. The province’s average nitrogen and phosphorus ratio of 1: 0.23, in some areas only 1: 0.001, or even without phosphate. At present, with the continuous increase of chemical fertilizer application, the phenomenon of unreasonable distribution and application rate becomes more and more obvious. In particular, after the implementation of the responsibility system for production in rural areas, many farmers appeared to have the tendency of blindly applying more fertilizers (mainly nitrogenous fertilizers)
