通过田间试验研究了磷酸二铵种肥与基肥配施对小麦生长发育及产量的影响 .结果表明 :在播种前采用 75kg/hm2 磷酸二铵作种肥 ,其余部分作基肥 ,较磷酸二铵全部作基肥可以促进冬前及春季小麦次生根发育 ,增加冬前群体和春季最高群体 ,提高亩成穗数 ,显著增加小麦产量
The effects of DAP fertilizer with basal fertilizer on the growth and yield of wheat were studied by field experiments.The results showed that 75kg / hm2 DAP as seed fertilizer and the rest as basal fertilizer before sowing were all better than those of DAP As a base fertilizer can promote the development of secondary roots of winter wheat and spring wheat, increase the population before winter and the highest group in spring, increase the number of mature ears and increase the yield of wheat significantly
