Avocados are a water-intensive crop, and the amount of water required varies depending on environmental conditions, soil characteristics, and the age of the tree.
A mature tree requires at least 1,000-1,300 mm of rain per year, and a tree may require up to 51 mm of water per week for plants planted in Mediterranean climates with dry and warm summers. In hot climates, the water consumption of an avocado tree is approximately 45 L/day in spring, 136 to 220 L/day in summer, and 121 L/day in autumn.
Since the root system of avocado trees is very shallow and mainly distributed in the top 20-60 cm of the soil, rainfall and artificial irrigation should try to keep the upper 15-20 cm of the soil moist.

Avocados have shallow and wide root systems that are sensitive to drought, and high-frequency precision irrigation and fertilization can reduce the risk of fruit trees suffering from drought stress.

It is recommended to use drip irrigation. If you use sprinkler irrigation, you need to increase the irrigation volume by 20%.
When the daily rainfall is greater than 10mm, effective rainfall will be considered and calculated as 60-70% of the rainfall.
The recommended amount is calculated based on adult fruit trees. If the tree is already a fruit-bearing tree but not yet mature, the irrigation amount can be reduced by 10-20% based on the growth of the fruit tree.

Assume that the recommended amount of irrigation is 5 mm/day, the spacing between drippers is 0.5 meters, the spacing between rows is 4.5 meters, and two drip irrigation pipes are laid, then the spacing between drip irrigation pipes is 4.5/2=2.25 meters, and the dripper flow rate is 1.0 liters/hour.
