冬季积尿浇麦是一项传统的增产措施。据测定,人尿中一般含氮0.5%、磷0.13%、钾0.19%、有机质3%。因此,小麦浇尿后能够显著提高土壤中氮、磷、钾等速效养分的含量,促进小麦幼苗的生长发育。可增产25～50千克小麦。小麦浇尿的具体时间,一般从“立冬”开始,至“清明”结束,但以封冻后到解冻前这段时间为最好。在土壤封冻前,一天之内随时都可以浇,但必须对等量清水稀释,以防烧苗;封冻期间要在中午或下午天气晴暖、土壤解冻时浇,不用对水稀释,可以直接浇。
Winter plot irrigation wheat is a traditional stimulation measures. According to the determination of human urine nitrogen generally 0.5%, phosphorus 0.13%, 0.19% potassium, organic matter 3%. Therefore, the watering of wheat could significantly increase the contents of available nutrients such as nitrogen, phosphorus and potassium in soils and promote the growth and development of wheat seedlings. Can increase 25 to 50 kg of wheat. The specific time of wheat pouring urine, usually from “beginning of winter ” began to “clear bright ” end, but after freezing to thaw before this time is best. In the soil frozen before the day can be poured at any time, but must be diluted with the same amount of water in order to prevent burning seedlings; frozen during noon or afternoon the weather is warm, the soil is thawed when pouring, do not dilute the water, you can direct .
