| 为提高植物生长调节剂对有刺黄龙果保果率和果实品质，以2年生长果形有刺黄龙果为试验材料，分两阶段开展试验。第一阶段，以不同植物生长调节剂28-表高芸苔素内酯0.4mg/L、6-苄氨基腺嘌呤100mg/L(６-ＢＡ)、ɑ-萘乙酸钠80mg/L(NAA)、赤霉素80mg/L(GA3)作为处理组，以喷施清水为对照组(CK)，喷施有刺黄龙果果实4次（每次间隔15d），对座果率和单果重进行分析比较，筛选出2个效果较好的植物生长调节剂进行第二阶段试验。第二阶段,以不同浓度2种植物生长调节剂进行互配组合（设置T1:GA3 20 mg/L+ NAA 20 mg/L、T2: GA3 50 mg/L+NAA 50 mg/L、T3: GA3 80 mg/L+NAA 80 mg/L、T4: GA3110 mg/L+NAA 110mg/L）作为试验处理组，以喷施清水为对照组(CK)，喷施有刺黄龙果果实4次（每次间隔15d），对果实农艺性状、外观形状和营养成分进行测定分析。结果表明，第一阶段试验的4种植物生长调节剂中GA3和NAA效果较好，可显著提高保果率和单果重；第二阶段试验的不同浓度植物生长调节剂组合4种处理均优于CK，其中，GA3 80 mg/L+NAA 80 mg/L 处理的效果最佳，对有刺黄龙果保果和果实品质最佳。 |

| In order to improve the plant growth regulator on fruit retention rate and fruit quality of yellow pitahaya, 2-year-old yellow pitahaya were used as materials, experiment was carried out in two stages. In the first stage, different plant growth regulators 28 -Epihomobrassinolide 0.4 mg/L,6-BA 100 mg/L, NAA 80 mg/L , GA3 80 mg/L as treatment, and clear water as control , sprayed with yellow pitahaya fruits four times (each interval of 15 d), and the fruit set rate and fruit weight of single fruit were analyzed. The fruiting rate and single fruit weight were analyzed and compared, and two more effective plant growth regulators were selected for the second stage of the experiment. In the second stage, two kinds of plant growth regulators with different concentrations were combined with each other (T1: GA3 20 mg/L+NAA 20 mg/L, T2: GA3 50 mg/L+NAA 50 mg/L, T3: GA3 80 mg/L+NAA 80 mg/L, T4: GA3110 mg/L+NAA 110 mg/L) as treatment , clear water as control, spraying yellow pitahaya fruits four times (15d interval each time), and determining and analyzing the agronomic traits, appearance and shape, and nutrient content of the fruits. The results showed that among the four plant growth regulators in the first stage of the experiment, GA3 and NAA were more effective, which could significantly increase the fruit retention rate and single fruit weight; in the second stage of the experiment, the four treatments were better than CK, among which, the GA3 80 mg/L+NAA 80 mg/L treatment was the most effective, and it had the best effect on the fruit retention and fruit quality of the yellow pitahaya fruit. |
