摘要
为探讨腐殖酸土壤调理剂在西瓜重茬地上的应用效果及对土壤化学性质的影响,通过施用不同含量的腐殖酸土壤调理剂对新蜜一号西瓜的坐果数、产量及土壤pH值和有机质、硝态氮、有效磷、速效钾的含量、阳离子交换量等指标的变化情况进行了分析。结果表明,与常规施肥相比,施用腐殖酸土壤调理剂可有效提高重茬地西瓜的坐果数、产量,同时对土壤化学性质产生有益影响。尤以常规施肥+50 kg·667 m^(-2)土壤调理剂4(T5)对生长指标的影响较大,其小区坐果数比常规施肥(CK)增加13.39%;小区产量比常规施肥(CK)增产21.69%。同时在土壤化学指标方面,T5处理在降低土壤的pH值,提高硝酸氮含量、速效钾含量等方面具有较大优势。综合各处理结果,腐殖酸土壤调理剂的施用能有效调节重茬地土壤的酸碱度,提高土壤养分含量,改善土壤的理化性质,从而提高作物产量,为重茬地的改良利用提供了新的技术方案。
In order to explore the effect of humic acid soil conditioner in watermelon continuous cropping fields and its influence on soil chemical properties, the fruit setting number, yield, soil pH value, organic matter, nitrate nitrogen, available phosphorus, available potassium content, and cation exchange capacity of Xinmi No. 1 watermelon were analyzed by applying different concentrations humic acid soil conditioner. The results showed that compared with conventional fertilization, the application of humic acid soil conditioner could effectively increase the number of fruit set and yield of watermelon in continuous cropping field, and had beneficial effects on soil chemical properties. Especially conventional fertilization+50 kg·667 m^(-2)soil conditioner 4(T5)has a great impact on biological indicators, and the number of fruit set in its plot is 13.39% higher than that of conventional fertilization(CK);The yield of the plot was 21.69% higher than that of conventional fertilization(CK). At the same time, in terms of soil chemical indicators, T5treatment had greater advantages in reducing soil pH, increasing nitrate nitrogen content, available potassium content, etc. According to the results of all treatments, the application of humic acid soil conditioner can effectively regulate the pH of the soil in the continuous cropping land, increase the soil nutrient content, improve the physical and chemical properties of the soil, thus increasing the crop yield, and providing a new technical scheme for the improvement and utilization of the continuous cropping land.
