水稻氮素调控施肥法的显著效果已受到普遍的重视。按该法规定,必须年年造造进行大田的数据测算工作,为此就需要相当数量的设备和人力,这在目前条件下,要在我区大面积推广该法是有困难的。为了解决这方面的困难,我们进行了模拟氮调法试验,经两年的实践,效果良好。模拟氮调法的根据是:认为科学的措施是符合客观规律的,在条件相对固定的情况下,其结果必然具有重现性。当前,我区的土壤状况、肥料结构、水稻品种、耕作方法都不可能
The remarkable effect of nitrogen fertilizer regulation has been paid more attention. According to the law, it is necessary to build data for the field measurement every year. This requires a considerable amount of equipment and manpower. Under the current conditions, it is difficult to promote this law on a large scale in our region. In order to solve this problem, we conducted a simulated nitrogen adjustment test. After two years of practice, the effect was good. The basis for the simulation of nitrogen regulation is that scientific measures are in line with objective laws, and the result is necessarily reproducible under relatively fixed conditions. At present, the soil condition, the structure of fertilizers, rice varieties and farming methods in our area are impossible
