1, temperature: 1 The annual average temperature is above 20℃, and the area with monthly average temperature above 12℃ is most suitable. When the temperature is lower than 0℃, adult trees will suffer from freezing injury, and young trees will have poor cold resistance.

2. Moisture: Huangpi is an evergreen fruit tree, which needs a humid environment and sufficient moisture. It grows well in areas with annual rainfall greater than 1500mm and even distribution. Too much water or too concentrated rainfall is not conducive to the growth, development, flowering and fruiting of wampee.

3. Illumination: Under the condition of sufficient illumination, the branches and leaves in the crown can absorb scattered light for photosynthesis, expand the photosynthetic area, enhance the accumulation of nutrients in the tree, expand the fruiting area, and improve the quality and yield of fruits; Insufficient light affects photosynthesis and nutrient accumulation of plants, which is unfavorable to plant growth and development.

4. Soil: wampee has low requirements for soil, and both clay loam and sandy loam can be planted, but different soils will have different effects on the life and yield of wampee plants. When planted on sandy loam with good drainage, fertile soil and deep soil layer, the tree will be strong, with long life and high and stable yield. Planting wampee on cohesive soil with poor soil quality, poor drainage and much accumulated water will lead to short life and low yield.
