我们北耿大队,根据气候、土质、作物的特点和肥料的特性,不断摸索合理施肥的方法。1972年,实行了“两改”,即将施农家肥满地扬改为集中条施;将化肥满垄撒改为深施覆盖,提高了肥效,增加了产量。1973年以来,我们又总结了“五看五定”施肥法。 Our North Geng Brigade, based on climate, soil, crop characteristics and characteristics of fertilizers, continue to explore ways to rational fertilization. In 1972, the “two reforms” were implemented, and the reform of the facilities for enriching farmers was changed to a centralized one; the conversion of the fertilizer-covered ridge to a deep-covered one was added to improve fertilizer efficiency and increase output. Since 1973, we have summarized the “five to five” fertilization method.
