摘要
【目的】进一步探讨HA(风化煤)在农业生产中的作用,为腐植酸资源的利用提供理论依据。【方法】采用田间试验的方法研究了HA与微肥配合施用对茼蒿生物量、品质的影响。【结果】试验表明:①所有施肥处理比对照有明显的增产效果,增产幅度为4.55%～18.08%,HA与微肥配施生物量比对照平均增加了14.14%;②所有施肥处理茼蒿VC(维生素c)含量比对照平均增加了32.97%,HA与微肥配施显著提高了VC含量;③所有施肥处理茼蒿可溶性糖含量、糖酸比(T/S)比对照都显著增加,增加幅度分别为20.4%～59.6%、17.82%～84.99%;HA与微肥配施的处理可溶性糖含量,T/S比对照都显著增加,平均增加了51.1%、60.79%。【结论】HA与微肥配施显著提高了茼蒿的生物量与品质。
[OBJECTIVE]In order to discuss the effect of the HA in the agricultural production and provide the theory direction for the using of the resource of the humic acid [METHOD]Field experiment was used to study the effects that the using of weathered coal and microelement fertilizer on the biologic yield and quality [RESULT]The result of the experiment shows,①all fertilizer treatments were obviously out-weighted the CK, the range is 4.55%-18.08%; the biologic yield of the treatments that HA and microelement fertilizer were applied together was increased by 14.14% than CK averagely,②the VC content of all fertilizer treatments were increased by 32.97% than CK averagely and the treatments that HA and microelement fertilizer were applied together were increased notably than CK, ③soluble content of candy and the T/S of all fertilizer treatments were increased notably, the range are 20.4%-59.6% andlT.82%-84.99% respectively, and the treatments that HA and microelement fertilizer were applied together were increased notably by 51.1% and 60.79% averagely and respectively than CK. [CONCLUSION]The biologic yield and quality of the treatments that HA and microelement fertilizer were applied together were increased notably than CK.
