摘要: 以度尾文旦柚为试材, 通过不同肥料及水分处理, 研究肥水对度尾文旦柚裂果及产量品质的影响。结果表明:每株年施腐熟禽粪肥25kg、草木灰7kg、氮磷钾复合肥4kg、尿素1kg、硝酸钙0.75kg、硫酸镁0.1kg、硫酸锌0.1kg, 在果实生长期田间持水量控制在65%75%, 能使度尾文旦柚裂果率降幅达42.5%52.2%;合理的肥水管理也有利于改善土壤理化性状, 提高文旦柚的产量和果实品质。Abstract: Effect of fertilization and water treatment on cracking, yield and quality of Duweiwendan pomelo fruits was studied.The results showed that by annual application of 25 kg rotten poultry manure, 7kg plant ash, 4kg nitrogen-phosphorus-potassium fertilizer, 1kg urea, 0.75 kg calcium nitrate, 0.1kg magnesium sulfate and 0.1kg zinc sulfate to each plant, and at the same time, controlling the water supply at 65% to 75% of the normal usage level during the fruiting period, the fruit cracking rate was reduced by 42.5% to 52.5%.In fact, appropriate fertilization and water management would, at the same time, benefit the soil physical and chemical properties while improving the quality of Duweiwendan pomelo.
