When using circular tree branches, PE pipes are selected as the branch pipes, arranged in a clockwise direction, with bidirectional infiltration for water supply. The branch pipes are arranged parallel to the tree rows, with one row of branch pipes and two rows of fruit trees. The integrated technology of water, fertilizer, medicine, and gas based on external embedded infiltration irrigation pipes has been widely promoted in fruit tree planting, and has been widely used in apples, cherries, oranges, grapes, mangoes, kiwifruit, etc., with good results, and has been in use for up to seven years. |
