摘要:

为探明氮磷钾配肥与微量元素施用对黑玉米产量和品质的影响,以自主选育的黑玉米‘SK9179’‘SK9176’和‘SK9115’为供试材料,采取多点对比重复试验设计,分别研究氮磷钾元素配比为2:1:2和2:1:1的配方肥,以及在此基础上追施微量元素锌和硼,对黑玉米产量和品质的影响。结果表明:2:1:2和2:1:1的2种氮磷钾配肥比例均可提高黑玉米产量和品质,尤以2:1:2配比效果较佳。在2:1:2比例下追施0.75%硫酸锌,黑玉米‘SK9179’产量最高达到18223.5 kg/hm2,玉米籽粒和玉米棒中花青苷含量高达0.40%和1.68%。硫酸锌和硼砂联合施用会降低黑玉米产量和品质。土壤中氮元素过高影响黑玉米中花青苷累积与产量形成,建议在黑玉米种植中适当减少氮肥施用量,增加磷肥和钾肥施用量。

Abstract:

To explore the impacts of applying nitrogen, phosphorus and potassium fertilizers, as well as micro elements, on the yield and quality of black corn, black corn ‘SK9179’, ‘SK9176’ and ‘SK9115’, which were self-selected breeding, were taken as test materials, and a multi-point comparison and repeated test design was carried out. The effects of formula fertilizers with nitrogen, phosphorus and potassium ratios of 2:1:2 and 2:1:1, and the supplementary application of the micro elements zinc and boron on the yield and quality of black corn were investigated. Both the 2:1:2 and 2:1:1 NPK ratios were found to enhance the yield and quality of black corn, with the ratio 2:1:2 demonstrating the most favorable results. Applying 0.75% zinc sulfate at the ratio of 2:1:2, the yield of ‘SK9179’ black corn reached the highest 18223.5 kg/hm2, and the anthocyanin contents in the corn kernels and cobs were as high as 0.40% and 1.68%, respectively. However, the combined application of zinc sulfate and borax was observed to decrease the yield and quality of black corn. An excessive amount of nitrogen in the soil had a negative impact on the accumulation of anthocyanins and the formation of yield in black corn. Therefore, it was recommended that during the cultivation of black corn, the application amount of nitrogen fertilizer should be reduced, while the application amounts of phosphorus and potassium fertilizers should be increased.
