为保养土壤质量、提高鲜食玉米品质,采用腐植酸可溶性液态有机肥进行试验,研究对玉米的生育期、病虫害发生情况、植株性状、鲜穗性状、产量情况及蒸煮口感等的影响。试验结果表明,施用腐植酸液态有机肥能提高鲜食玉米的品质,与对照相比,在气味风味、柔嫩性上有明显优势,感官品质、色泽、糯度、皮薄厚等品质也有所提高;在抽雄吐丝期喷施叶面肥能促进玉米授粉,提高授粉效率,减少秃尖的发生;在施足基肥的情况下,追肥施用腐植酸液态有机肥对鲜食玉米产量及穗长、穗粗等鲜穗性状无明显影响。
In order to maintain the soil quality and improve the quality of fresh corn, humic acid soluble liquid organic fertilizer was used to test the effects of corn growth period, pest and disease occurrence, plant traits, fresh ear traits, yield and cooking taste. The results showed that the application of humic acid liquid organic fertilizer could improve the quality of fresh corn. Compared with the control, the humic acid liquid organic fertilizer had obvious advantages in flavor and tenderness. The quality of sensory quality, color, glutinousness, Spraying foliar application during the sprouting stage can promote the pollination of corn, improve pollination efficiency and reduce the occurrence of bald tip. Under the condition of applying adequate fertilizer, the application of humic acid liquid organic fertilizer on fresh corn yield and spike length, spike Coarse fresh spike traits no significant effect.
