In the autumn of 1979, we conducted nitrogen application experiment in different periods of wheat to explore the relationship between nitrogen fertilizer and spike number, grain number and 1000-grain weight, with a view to achieve better yield increase without increasing the amount of fertilizer. First, the test method Fertility test in general, basal fat per acre pigs 20 Tam, phosphate fertilizer facilities, 80 pounds per mu. Community area of 0.15 acres, each small area to open a small groove, something (Tulun) head, set two protection line.
