摘  要：
为探明土壤调理剂在豫东黄潮土区冬小麦上的应用效果,采用大田试验,研究了施用土壤调理剂对土壤理化性质、冬小麦群体动态、冬小麦产量及其构成因素的影响。2a多点试验结果表明,在正常旋耕施肥的基础上施用30kg/hm2土壤调理剂能降低土壤容重,增加土壤孔隙度,增强土壤保水性,促进小麦根系生长;2a4点处理3(配方肥750kg/hm2+旋耕12cm+土壤调理剂30kg/hm2)的平均成穗数、穗粒数和千粒重较处理2(配方肥750kg/hm2+旋耕12cm)分别提高12.20%、10.14%和4.55%,平均增产21.9%(P<0.01)。在目前耕作制度下增施土壤调理剂是小麦栽培中值得推广的新技术。

摘  要：
To explore the application effect of soil conditioner on winter wheat in yellow moist soil of eastern Henan plain,a field experiment was conducted to study the effect of soil conditioner on the physical and chemical properties of soil,the population dynamics of wheat,and the yield and its components of winter wheat.The experiment results of 2 years and multi-points showed that,on the basis of normal rotary tillage and fertilization,applying 30 kg/ha soil conditioner could decrease the soil bulk density,increase the soil porosity,improve the soil water-retaining property,and promote the root growth.In average,the spike number,grain number per spike,1 000-kernel weight and grain yield of treatment 3(fertilizer 750 kg/ha+rotary tillage 12 cm+soil conditioner 30 kg/ha) were respectively 12.20%,10.14%,4.55% and 21.9%(P<0.01) higher than those of treatment 2(fertilizer 750 kg/ha+rotary tillage 12 cm).This suggested that the application of soil conditioner may be a new technology worth to be popularized in the present tillage system.
