摘要
在大田条件下,以常规复合肥处理为对照,探究质量分数2%、4%、6%、8%腐植酸的复合肥对辣椒产量和品质的影响,并在连作条件下探究腐植酸复合肥的使用效果,设置常规施肥与6%腐植酸复合肥进行连续4年对比试验。结果表明:腐植酸可显著提升辣椒的产量和品质,且综合提升效果与腐植酸质量分数成正比;综合效益、产量及各项品质指标,6%腐植酸复合肥为最佳处理,当年即较对照组增产14.07%;腐植酸复合肥可有效减少连作对辣椒产量和品质的影响,综合产量、品质降低幅度明显小于对照组;第4年,6%腐植酸复合肥处理较常规施肥增产达33.6%。
The study was carried out in field conditions and use conventional compound fertilizer as the control group to explore the effect of compound fertilizers containing 2%,4%,6%,or 8%humic acid on the yield and quality of chilli.The effect of humic acid-compound fertilizer treatment under continuous cropping conditions was investigated,6%humic acid-compound fertilizer was conducted for four consecutive years and using conventional compound fertilizer as the control group.The results show that humic acid fertilization significantly improved the yield and quality of chilli,and the overall improvement was directly proportional to the dosage of humic acid.An evaluation based on benefit,yield,and various quality indicators concludes that compound fertilizer with 6%humic acid was the optimal ratio,which increased the yield by 14.07%in the first year compared to that in the control group.The application of humic acid-compound fertilizer effectively reduced the impact of continuous cropping on the yield and quality of chilli,and the combined decline in the yield and quality was significantly less than that in the control group.In the fourth year,the yield of 6%humic acid-compound fertilizer treatment was 33.6%higher than that of conventional fertilizer.
