一、确保全苗。一般小麦播种后到三叶期,正处在气温回暖、风大风多、跑墒蒸发快的时期,往往有些麦田出苗不齐,不全,甚至缺苗断垄严重。凡因播种过浅种子落干或过深麦苗曲黄顶不出土的,应采取浇水润墒、踩压提墒、揭土露苗或铁耙松土等措施,加以抢救扶苗。凡因播后降雨地表板结影响出苗的,应及时用钉齿耙松土,破除板结,避免曲黄,利于幼苗出土。凡麦苗瘦弱发黄的地块,可用石(石袞)子压青,以三叶期为最好,可促使幼苗蹲实健壮。凡因地下害虫 First, to ensure that all seedlings. After the general wheat sowing to the three-leaf stage, is in the warmer temperatures, strong winds, run moisture evaporate quickly period, often some of the emergence of wheat fields missing, incomplete, and even lack of seedlings severely damaged. Where the sowing of shallow seeds fall dry or too dark yellow topped yellow top not unearthed, watering and moisture should be taken to step on the pressure to mention soil moisture, exposing soil seedlings or iron rake loosening measures to be rescued. Where due to sowing rain surface patches affect sprouting, should promptly rake with razor rake, break the compaction, to avoid the yellow song, which will help unearthed seedlings. Where wheat seedlings thin yellow patches, available stone (stone) sub-pressure green, with the best three-leaf stage, can promote seedling squatting solid. Because of underground pests
