为考察有机肥部分替代化肥在洋葱生产上的应用效果,开展了田间小区试验。试验共设置3个处理,分别为常规施肥(T1)、常规施肥+有机肥30 m3/hm2(T2)、常规施肥减肥10%+有机肥30 m3/hm2(T3),考察了不同施肥处理的洋葱生长性状、产量及经济效益。结果表明:与T1处理相比,T2、T3处理的洋葱球高、球茎、单球质量均显著提高,产量分别显著提高了6.7%、11.3%;T3处理的经济效益最好。有机肥部分替代化肥可显著促进洋葱生长、提高产量及经济效益,对洋葱的绿色高效生产具有积极的推动作用。
A field plot experiment is conducted to investigate the effects of partially substituting chemical fertilizers with organic fertilizer in onion production. The experiment includes three treatments: conventional fertilization (T1), conventional fertilization + 30 m3/hm2 of organic fertilizer (T2), and conventional fertilization with a 10% reduction + 30 m3/hm2 of organic fertilizer (T3). The growth traits, yield, and economic benefits of onion under different fertilization treatments are measured. The results show that compared with the T1 treatment, T2 and T3 treatments significantly increase the bulb height, bulb diameter, and single-bulb weight of onion, with yields significantly increasing by 6.7% and 11.3%, respectively. The T3 treatment achieves the best economic benefits. Partial substitution of chemical fertilizers with organic fertilizer can significantly promote onion growth, increase yield, and improve economic benefits, demonstrating positive implications for the green and efficient production of onion.
