早春来临,气温回升。冬小麦经过漫长的越冬阶段后,生长点开始发芽出土。此时,冬小麦处于穗分化期,是决定麦穗和小穗多少的关键时机。抓紧管理,能夺取冬麦高产。一、耙地松土,增温保墒。早春解冻后,应及时耙地,疏松土壤,以提高地温,助苗出土,促苗早发。结合顶凌耙地,每亩撒十至十五斤硝铵,效果更好。二、深施化肥。我所几年试验和各地生产实践证明,早春深施化肥,既解决早春低温、
Early spring is coming, the temperature picks up. After a long winter winter wheat stage, the growing point began to germinate unearthed. At this point, winter wheat in the ear differentiation stage, is to determine the number of wheat and spikelet key timing. Pay close attention to management, can win winter wheat high yield. First, rake to soil, warming soil moisture. After thawing in early spring, it should promptly harrow and loosen the soil in order to raise the ground temperature, help the seedlings to emerge, and promote early seedling emergence. Combined with top Ling rake, sprinkle ten to fifteen pounds of ammonium nitrate per acre, the better. Second, the deep application of fertilizer. I test a few years and production practices around prove that deep fertilization in early spring, not only to solve the early spring low temperature,
