春小麦一般播种后25天左右出苗。要根据春麦的发育特点,积极主动地采用肥水、耕作、植保等措施,不断地处理好生长发育与外界条件的矛盾,促使它向高产稳产方面转化。一、前期以肥为主,肥水齐攻。一般在出苗后15天左右(即二叶一心期),进行第一次施肥、浇水,施肥量应占全生育期追肥总量的60%左右,施肥后立即灌水,水量要小,大水会淹淤小苗,而且还会使地温下降过多,影响分蘗。第二次施肥、浇水在拔节期进行,施肥量占追肥
Spring wheat generally 25 days after sowing emergence. According to the characteristics of spring wheat development, proactive use of fertilizer, farming, plant protection and other measures, continue to deal with the contradiction between growth and development and external conditions, prompting it to high and stable yield aspects of transformation. First, the main pre-fat, fertilizer and water attack. Generally about 15 days after emergence (ie two leaves one heart period), the first fertilization, watering, fertilization should account for about 60% of the total growth during the top dressing, irrigation immediately after fertilization, the amount of water to be small, large water Will be dredging silt seedlings, but also make the ground temperature dropped too much, affecting tillering. The second fertilization, watering in the jointing stage, the amount of fertilizer accounted for dressing
