南逗迈4号芒设施栽培技术研究

为了改善栽培品种结构，探讨设施栽培产期调节技术，调节芒果鲜果供应市场时间，在南宁建设设施大棚，2016年~2019年对南逗迈4号芒开展设施栽培模式下产期调节试验。结果表明，在设施栽培模式下，南逗迈4号芒宜在4月上旬前修剪，7月-8月促花2-3次，调控在8月上旬至10月下旬开花坐果，12月下旬果实成熟。南逗迈4号芒适合作为设施栽培产期调节品种，12月成熟平均单果重366.4g，可溶性固形物含量19.5%，可食率73%。高接换种后第二年每667㎡产量470.4kg，第三年每667㎡产量959.4kg，第四年每667㎡产量1049.1kg，品种产期调节生产性状优，是具有发展前景的芒果设施栽培产期调节新品种。

Study on Protected Cultivation Technology of mango variety Nan Doc Mai No.4

In order to improve the structure of cultivated varieties and explore the cultivation techniques of production period regulation, the greenhouse was constructed in Nanning, and the production period regulation experiment was carried out in the protected cultivation mode of Nan Doc Mai No.4 from 2016 to 2019. The results showed that under the protected cultivation mode, Nan Doc Mai No.4 mango variety should be pruned in the first ten days of April, the shoots should be controlled once in March, the flowers should be promoted 2-3 times from July to August, the flowering and fruit setting should be controlled from the first ten days of August to the last ten days of October, and the fruits will mature in the last ten days of December. The average fruit weight of Nan Doc Mai No.4 was 12.4% and the average fruit weight of Nan Doc Mai No.4 was 19.4%. The yield per 667 m2 is 470.4kg/667m2 in the second year, 959.4kg/667m2 in the third year and 1049.1kg/667m2 in the fourth year after high grafting. It is a new mango variety with development prospect.
