摘要: 为了研究生物有机肥在谷子种植中的应用效果,获得适合于河北地区种植谷子的最佳生物有机肥施用量,以‘冀谷35’为供试品种,于2023年6月—9月进行田间小区试验,共设计6个处理,分别为:不施肥处理(DCK1)、纯化肥处理(DCK2)、生物有机肥2250 kg/hm2处理(D1)、生物有机肥4500 kg/hm2处理(D2)、生物有机肥6750 kg/hm2处理(D3)、生物有机肥9000 kg/hm2处理(D4)。分析生物有机肥不同施用量对谷子株高、茎粗、叶面积、SPAD值、地上生物量以及地下生物量的影响。结果表明:施用生物有机肥对谷子的生长性状具有显著的积极作用,且不同施用量对谷子生长的影响存在差异,其中,D3、D4处理的效果较好,但从节约资源角度来看,推荐选择D3处理作为种植谷子的最佳生物有机肥施用量,即施用生物有机肥6750 kg/hm2,从而实现生物有机肥替代化肥的目的,同时减少对环境的负面影响,促进农业的可持续发展,也为进一步优化谷子种植技术、提升谷子产量和品质奠定了坚实的基础。

Abstract:

To study the application effect of bio-organic fertilizer in millet planting, and obtain the best bio-organic fertilizer application rate for planting millet in Hebei area, the field experiment of ‘Jigu 35’ was carried out from June 2023 to September 2023, and six treatments were set as followed: no fertilization (DCK1), pure chemical fertilizer (DCK2), 2250 kg/hm2 bio-organic fertilizer (D1), 4500 kg/hm2 bio-organic fertilizer (D2), 6750 kg/hm2 bio-organic fertilizer (D3), 9000 kg/hm2 bio-organic fertilizer (D4). The effects of different application rates of bio-organic fertilizer on plant height, stem diameter, leaf area, SPAD value, aboveground biomass and underground biomass of millet were analyzed. The results showed that the application of bio-organic fertilizer had a significant positive effect on the growth traits of millet, and the effects of different application amounts on the growth of millet were different. Among them, D3 and D4 treatments had better effects. However, from the perspective of saving resources, it was recommended to choose D3 treatment as the optimal application amount of bio-organic fertilizer for planting millet, which was 6750 kg/hm2 of bio-organic fertilizer, so as to achieve the purpose of replacing chemical fertilizer with bio-organic fertilizer, while reducing the negative impact on the environment, and promoting the sustainable development of agriculture. It also laid a solid foundation for further optimizing millet planting technology and improving the yield and quality of millet.
