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。
In order to find out the application effects of soil conditioner on winter wheat in the yellow soil region of eastern Henan, field experiments were conducted to study the effects of soil conditioner on soil physical and chemical properties, population dynamics of winter wheat, winter wheat yield and its components. 2a multi-point test results show that the application of 30kg / hm2 soil conditioner on the basis of normal rotary fertilization can reduce soil bulk density, increase soil porosity, enhance soil water retention and promote root growth; 2a4 treatment 3 (750kg / hm2 + rotary cultivating 12cm + soil conditioner 30kg / hm2) increased by 12.20%, 10.14% and 4.55% respectively compared with treatment 2 (fertilizer 750kg / hm2 + rotary cultivating 12cm) % (P <0.01). Under the current farming system, the application of soil conditioner is a new technique worth promoting in wheat cultivation.
