近几年来,随着施肥水平和栽培技术的不断提高,不少地区在施用种肥方面,除氮肥外,还增施了磷肥,并有将纯粪(大粪、猪粪、鸡粪、羊老粪等)或油饼用作种肥的。如果将上述这些肥料与种子分开施用,不仅会延缓幼苗对肥料的利用,而且增加播种工序,浪费劳畜力;如果仅以化肥作种肥,与种子一起播入,则因用量较大,易造成流量不匀,不利出苗。不少试验资料证明,象小麦这 In recent years, with the continuous improvement of fertilization levels and cultivation techniques, many kinds of fertilizers have been applied in many areas. In addition to nitrogen fertilizers, phosphate fertilizers have also been added to these areas. In addition, pure manure (excrement, pig manure, chicken manure, Manure, etc.) or oil cake as a kind of fertilizer. If these above-mentioned fertilizers and seeds are used separately, it will not only delay the utilization of fertilizers by the seedlings, but also increase the sowing process, which is a waste of labor force. If fertilizers are used only as fertilizer and are sown with seeds, Uneven flow, adverse emergence. A lot of test data prove that, like wheat
