增施肥料对粮食增产是一项重要措施。西欧的经验表明,在农业增产诸措施中,施肥的增产效果约占40—60％。八十年代,我国进行的化肥网的大量资料说明,在相同条件下,如氮、磷肥配合适当,施肥的比不施肥的平均增产小麦56.6％,玉米46.19％,其增产幅度与国外大体一致。建国30多年,全省耕地减少了16％,粮食产量却增加了两倍,除其它措施外,
Increasing fertilization of grain production is an important measure. The experience of Western Europe shows that in the measures for increasing agricultural output, the yield increase effect of fertilization accounts for about 40-60%. In the 1980s, a large amount of data from China’s chemical fertilizer network showed that under the same conditions, such as nitrogen and phosphorus fertilizers, with an appropriate increase of 56.6% of wheat and 46.19% of maize compared with no fertilization, the yield increase is generally consistent with that of foreign countries. In the more than 30 years since the founding of the People’s Republic, the cultivated area in the province has been reduced by 16% while the grain output has tripled. Among other measures,
