园地环境符合 NY 5023 的要求，土壤和气候等条件适合龙眼生长。
坡度在 20° 以下。土壤质地良好，有机质含量 1% 以上，pH 5.5~6.5。
年均温 20~23.5°C，最低月平均温度高于 11°C，多年平均极端低温高于 -1.5°C。
苗木质量按 NY/T 354 执行。
可采用株行距为 5 m×6 m、4 m×6 m 或 4 m×5 m 的种植密度，平地和土壤肥力较好的园地宜疏植，坡度较大的园地可适当缩小行间距，密植的园地后期视植株生长情况进行疏伐。
The orchard environment shall comply with the requirements of NY 5023, and the soil and climate conditions shall be suitable for longan growth.
The slope shall be below 20°. The soil texture shall be good, with organic matter content above 1% and pH 5.5~6.5.
The annual average temperature shall be 20~23.5°C, the lowest monthly average temperature shall be above 11°C, and the multi-year average extreme low temperature shall be above -1.5°C.
Seedling quality shall comply with NY/T 354.
Planting densities such as 5 m×6 m, 4 m×6 m or 4 m×5 m may be adopted; flat land and fertile orchards should be sparsely planted, while orchards on steeper slopes may appropriately reduce row spacing; densely planted orchards should be thinned later according to plant growth.
