A team of two mines farm in a large area (area 20 acres) application results, 400 kilograms per mu fertilizer coal fertilizer for the base, the average yield per acre mulberry reached 547 pounds, milled in the field there is such a high yield, in the past is very rare. According to the sampling results of the other 50 species test, the coal fertilizer fertilizer of the plant height, root, leaf width, stalks stout, full grain, 1000-grain weight.
