摘要:

为了进一步探究肥料、除草剂和硒配施对谷子品质的影响,优化谷子栽培技术。以‘晋谷21号’为试材,采用5因素5水平的二次通用旋转组合设计,研究N、P2O5、K2O、Se和MSF除草剂混施对谷子品质指标的影响。采用主成分分析方法对谷子的蛋白质、脂肪、叶酸、凝胶稠度、淀粉酶、碱消化值、黄色素和硒等8项品质指标进行了分析,获得代表8个品质指标58.14%的信息量的综合品质。N × K2O、N × MSF、K2O × MSF相互作用对‘晋谷21号’综合品质影响显著。N、P2O5、K2O、Se和MSF优化栽培条件分别为109.88 kg/hm2、99.20 kg/hm2、110.91 kg/hm2、87.58 g/hm2和419.35 g/hm2,最高预测综合品质为57.68。本研究为谷子生产中合理配施氮、磷、钾、硒和除草剂提供参考,为优质谷子的调优栽培管理和目标化种植提供理论依据。

Abstract:

This study explored the effect of combined application of fertilizer, herbicide, and selenium (Se) on the grain quality of foxtail millet in order to optimize the foxtail millet cultivation techniques. ‘Jingu 21’ was used as material, a quadratic general rotation combination design with five factors and five levels was set to study the effects of combined application of nitrogen (N), tetraphosphorus decaoxide (P2O5), potassium oxide (K2O), tribenuron-methyl (TBM) herbicide, and Se on the quality of foxtail millet. Principal component analysis was performed to evaluate the eight quality indicators of foxtail millet, including protein, fat, folate, gel consistency, amylase, alkali digestion value, yellow pigment and selenium. The first principal component, which could explain 58.14% of the total variance of grain quality, was chosen as the comprehensive quality. N×K2O, N×MSF, and K2O×MSF interactions had significance influence on the comprehensive grain quality of ‘Jingu 21’. The recommended cultivation conditions of N, P2O5, K2O, Se and MSF were 109.88 kg/hm2, 99.20 kg/hm2, 110.91 kg/hm2, 87.58 g/hm2, and 419.35 g/hm2 respectively, and the highest predicted comprehensive quality was 57.68. This study provided support for the use of nitrogen, phosphorus, potassium, selenium and herbicide in an optimal combination for foxtail millet production, and provided a theoretical basis for the optimal cultivation management and targeted planting of high-quality foxtail millet.
