本试验研究了基肥氮磷钾不同比例配施对温郁金产量与品质的影响,为提高温郁金产量及品质提供科学依据.本研究采用大田试验,设置 4 个不同的施肥配方,各处理基肥用量均为 750 kg·hm-2.结果表明,在氮磷钾总用量相等的前提下,基施配方肥 2 的温郁金产量最高,与常规施肥比较,温郁金地下部分根茎、块根分别增产 11.3%、17.9%.配方肥 1 和 3 相较常规施肥也提高了温郁金的产量,但统计上无显著差异.与常规施肥相比,配方肥处理提高了温郁金中氮和磷含量.同时,基施配方肥还可以提高根茎、块根中 Ca、Mg及微量元素 Zn、B等含量.综上,基肥施用配方肥 2 既能提高温郁金产量,又能提高根茎、块根中的大量元素及中微量元素含量,具有较好的推广应用价值.
In this experiment,the effects of different proportions of nitrogen,phosphorus and potassium on the yield and quality of Curcuma wenyujin were studied.In this study,four different fertilization formulations were set up using field experiments,and the basal fertilizer dosage of each treatment was 750 kg·hm-2.The results showed that under the premise of equal total use of nitrogen,phosphorus and potassium,the yield of Curcuma wenyujin was the highest under basal application of formula fertilizer 2,and the yield of rhizomes and tubers of Curcuma wenyujin underground was increased by 11.3%and 17.9%,respectively,compared with conventional fertilization.Compared with conventional fertilization,formula fertilizer 1 and 3 also increased the yield of Curcuma wenyujin,but there was no significant difference.Compared with conventional fertilization,the nitrogen and phosphorus content in Curcuma wenyujin was increased by formula fertilizer treatment.At the same time,basal application of formula fertilizer can also increase the content of Ca,Mg and trace elements Zn and B in rhizomes and tubers.In summary,the application of basal fertilizer formula fertilizer 2 can not only increase the yield of Curcuma wenyujin,but also increase the content of macroelements and medium and trace elements in rhizomes and tubers,which has good promotion and application value.
