摘要： 为了解决豫东平原潮土区麦田因多年旋耕导致耕层过浅、土壤物理性状变差、根系生长发育不良等问题，利用商丘沃力农业技术服务有限公司发明专利产品，通过田间试验与土壤分析方法，在平衡配方施肥的基础上，应用松土促根剂，耕层土壤容重明显降低，土质疏松，土壤孔隙度增加，通透状况改善，土壤含水量也有所提高，小麦根系生长环境得到改善，各生育期根系干重增加，有效协调了小麦产量构成3因素，平均穗数增加63.5万穗/hm2、穗粒数增加1.8粒、千粒重提高1.7 g。小麦产量(y)与松土促根剂用量(x)之间呈二次曲线回归关系，其效应方程为：y=8670.4257+128.6471x-3.0432x2，F处理间=152.43**＞F0.01=5.64；F重复间=3.73＜F0.05=4.10。就改土、增产的综合效应而言，松土促根剂的适宜用量为15~22.5 kg/hm2，可在豫东平原潮土区旋耕麦田现行生产、生态、技术条件下推广应用。

Abstract: In order to solve shallow topsoil, bad condition of soil physical properties and roots’ growth in wheat field due to years of rotary tillage, based on balanced fertilization and the application of national invention patent product produced by Woli agricultural technology service co., LTD in Shanqiu, we carried out the study by doing field experiments and soil analysis. After application of root promoter, soil bulk density of arable layer decreased obviously, soil became looser, soil porosity increased, permeability and soil moisture content were improved, wheat root growth environment was also improved, the root dry weight increased, and the three factors were coordinated effectively. The average number of spike increased to 635000 spike per hm2, spike grain number increased by 1.8 and thousand seed weight increased by 1.7 g. There was a curve regression relationship between wheat yield (y) and content of root promoter (x) and its effect equation was: y=8670.4257 128.6471x-3.0432x2, Ftreatment=152.43**＞F0.01=5.64；Frepeat=3.73＜F0.05=4.10. In terms of the comprehensive effect on improving the soil quality and increasing productivity, the suitable dosage of root promoter was 15-22.5 kg/hm2, it could be applied to rotary tillage wheat fields under current productive, ecological and technological conditions in the eastern Henan plain.
