西北麦区小麦大部分处于越冬期,小麦苗情和墒情总体较好。部分田块因抢墒早播,出现旺长,个别地块旱象抬头,小麦条锈病见病早,菌源基数大。旱地麦管理要注意以下四点:耙耱保墒,顶凌追肥。对底肥不足、苗黄苗弱的麦田,结合顶凌耙耱或小雨后趁墒追肥,亩施4-5公斤尿素,促转化升级。对冬前群体过大、土壤肥力较高的旱地麦田,返青期不宜追肥,可在起身至拔节期趁雨酌情追肥。镇压划锄,提墒增温。早春小麦返青前后镇压可提墒保墒,促进
Most wheat in the northwest wheat area is overwintering, and the wheat seedling and soil moisture are generally good. Part of the plots due to pre-seize the soil moisture, appear prosperous, drought-prone elevation of individual plots, wheat stripe rust see early illness, a large source of bacteria. Dryland wheat management should pay attention to the following four points: rake 耱 soil moisture, top Ling top dressing. On the lack of base fertilizer, seedling weak yellow wheat field, combined with top Ling rake 耱 or light rain while taking advantage of fertilizer, Mushi 4-5 kg of urea, and promote transformation. To the winter before the group is too large, high soil fertility of dryland wheat fields, greening should not be topdressing, can get up to the jointing period while the appropriate top dressing. Repression plank hoe, mention moisture warming. Before and after the spring wheat back to green suppression can be entrusted moisture soil conservation, promotion
