摘要：

以紫云冰脆李为试材，测定分析其果实大小、色泽、品质、果核、核仁大小和产量以及农药残留等指标，研究提质技术与常规管理对冰脆李的影响。通过提质技术应用，紫云冰脆李的单果重、纵径、横径、果形指数、可溶性固形物、可溶性糖、糖酸比、固酸比、果柄粗、红绿值、黄蓝值、果核和核仁的长度、宽度与厚度、产量均显著高于常规管理，其中可溶性固形物提高13.87%，可溶性糖提高11.75%，单株产量增加37.33%，单位面积产量增加37.37%，可滴定酸降低13.83%。农药残留检测表明，除多菌灵、苯醚甲环唑、氯氟青菊酯几种农药在常规管理处理中被检出外，其余均未检出，即使检出农药也远低于绿色食品的限定值。

Abstract:

Taking Ziyun plum as the research object, through measuring and analyzing indexes such as fruit size, color, quality, kernel, yield, pesticide residues, etc., the effects of quality improvement techniques and common management techniques on fruit quality and yield were studied. The results showed that the application of the techniques could significantly improve the fruit quality of Ziyun plum. Under the quality improvement techniques, single fruit weight, fruit longitudinal diameter, fruit transverse diameter, fruit shape index, soluble solids, soluble sugar, sugar-acid ratio, fruit stalk diameter, solid-acid ratio, red-green value, yellow-blue value, the length, width and thickness of fruit kernel, and the yield of Ziyun plum were significantly higher than those of the control. The soluble solids content, soluble sugar content, yield per plant and yield per unit area were increased by 13.87%, 11.75%, 37.33% and 37.37%, respectively, while the content of titratable acid was decreased by 13.83%. Only carbendazim, difenoconazole and cyhalothrin were detected in the conventional pesticide residue control, and their detected values were far lower than the limit value of green food, and other pesticides were not detected.

Key words: plum, quality, yield, green food, quality improvement techniques
