摘要
通过田间小区试验,研究了盐碱地上施用黄腐酸复合肥对小麦生长及土壤理化性质的影响。结果显示,试验所用黄腐酸复合肥可较好地提供氮磷钾养分,提高养分利用率,增加小麦产量和收入,比对照增产21.84%~36.17%,比普通复合肥增产9.58%~11.76%,且均达显著水平,比普通复合肥每公顷平均增收600元左右;在低量黄腐酸复合肥基础上配施黄腐酸钙镁肥与普通复合肥比,对供试盐碱地小麦产量没有显著影响;黄腐酸复合肥在改良盐碱地酸碱度方面效果不显著。
The effects of fulvic acid compound fertilizer on wheat growth and soil physicochemical properties were studied by field plot experiments in saline-alkali soil.The results showed that compared with CK and common compound fertilizer,the fulvic acid compound fertilizer significantly increased the wheat yield by 21.84%~36.17%and 9.58%~11.76%,indicating that fulvic acid compound fertilizer improved soil nutrient content and use efficiency,yield and income.Compared with common compound fertilizer,the income increased about 600 yuan/hm^2.In addition,fulvic acid-Ca-Mg fertilizer on the basis of low fulvic acid compound fertilizer had no significant effect on the yield of wheat compared with common compound fertilizer.There was no significant effect on regulating saline-alkali soil pH.
