小麦施用暖沟粪,既可保温防寒,减轻冻害,又可补充肥料,作到冬肥春用,是一项有效的增产措施。但这也不是绝对的,生产实践与调查表明,下述麦田施用暖沟粪比较适宜。一、沙地麦。沙土地结构松散,漏水、漏肥、透风跑气,吸热、散热皆快,地温忽冷忽热变化大,冬季小麦易受冻害,也易患根腐病。故应优先给沙地麦施暖沟粪。二、晚茬麦。晚麦一般较弱,叶窄色浅,根稀蘖少,抗冻能力差,也应优先施用暖沟粪。三、浅播麦。由于种种原因,导致小麦播种偏浅,分蘖节覆土不足2厘米者,为了防止麦苗受冻害,也应施用暖沟粪。
Wheat drench warm dung, both insulation cold, reduce frost damage, but also add fertilizer for winter fertilizer use, is an effective stimulation measures. However, this is not absolute. Production practices and surveys show that it is more appropriate to use warm dung in the following wheat fields. First, sandy wheat. Sand land structure is loose, leaking, leakage of fertilizer, ventilation run gas, heat absorption, heat are fast, ground temperature changes suddenly hot and cold, winter wheat susceptible to frost damage, but also susceptible to root rot. Therefore, priority should be given to the sand Mai Mai dung. Second, late crop wheat. Late wheat is generally weak, narrow leaves light color, less sparse roots, antifreeze poor, should also give priority to the application of warm dung. Third, light broadcast wheat. Due to various reasons, leading to shallow sowing of wheat, tillering section covered less than 2 cm, in order to prevent frost damage, should also be applied warm dung.
