近年来,随着生产水平的普遍提高,淮北地区的小麦单产也有了较大幅度的上升.大部分地区小麦产量的提高,除更新品种外,主要还是靠增加氮磷化肥的投入来实现的.要使有限的肥料产生最大的经济效益和生态效益,经济合理施用是关键.从目前大面积生产情况看,盲目施用化肥的问题较为突出,因氮磷化肥施用不当而造成的倒伏、减产等现象时有发生.为此,研究氮磷化肥对小麦生育、产量以及品质的影响,找出淮北地区氮磷化肥的最佳经济用量很有必要.自1983年以来,我们组织了淮北地区的有关农业和科研单位协作进行本项研究.
In recent years, with the general improvement of production level, the yield of wheat in Huaibei area has also risen by a big margin, and in most areas, the increase of wheat output is mainly achieved by increasing the input of nitrogen and phosphorus fertilizers besides the renewal of varieties. To make limited fertilizer produce the greatest economic and ecological benefits, economic and rational application is the key.From the current situation of large-scale production, the problem of blind application of chemical fertilizers is more prominent due to improper use of nitrogen and phosphorus fertilizer caused by the phenomenon of lodging, Therefore, it is necessary to study the effect of nitrogen and phosphorus fertilizers on the growth, yield and quality of wheat and find out the best economic use of nitrogen and phosphorus fertilizers in Huaibei area.We have organized the agriculture-related projects in Huaibei since 1983 And research units in collaboration with this study.
