摘要
采用全生育期温室盆栽试验方法,以氯化钾处理为对照,研究了鄂西黄壤和紫色土上小麦施用杂卤石的效果。结果表明,在2种土壤上小麦施用杂卤石均显著增产,黄壤和紫色土上小麦子粒产量分别比对照高28.7%和46.6%,主要是由于杂卤石处理显著增加了小麦的有效穗数,黄壤和紫色土上小麦有效穗数分别比对照高31.2%和37.5%。在黄壤上,杂卤石处理的小麦,其钙和镁吸收量与对照基本持平,硫吸收量比对照增加44.6%;在紫色土上,施用杂卤石显著提高了小麦对钙、镁和硫的吸收量,提高幅度分别为7.7%、25.0%和81.8%,杂卤石在紫色土小麦上的施用效果比黄壤好,与紫色土有效钙、有效镁和有效硫的含量均较低有关。
The effect of polyhalite on wheat in yellow and purple soils collected from west Hubei province was studied by a greenhouse pot experiment in whole wheat growth duration.Results showed that,in yellow and purple soils,polyhalite treatment significantly in⁃creased grain yield of wheat by 28.7%and 46.6%respectively compared with CK(KCl)treatment,which mainly because polyhalite treatment significantly increased the amount of effective panicle by 31.2%and 37.5%in yellow and purple soils,respectively.In yel⁃low soil,Ca and Mg uptake in wheat plant from polyhalite treatment was almost identical to that from CK treatment,whereas S uptake from polyhalite treatment was significantly higher than that from CK treatment by 44.6%;In purple soil,polyhalite treatment signifi⁃cantly increased Ca,Mg and S uptake in wheat plant by 7.7%,25.0%and 81.8%,respectively.The above results implied that,wheat responded better to polyhalite in purple soil than in yellow soil,and mainly because the effective Ca,Mg and S content in purple soil was obviously lower than that in yellow soil.
