During 2020 to 2021, on furrow irrigation and sprinkler irrigation experiments, the treatment methods were reduced total water consumption by 10%, 20% comparing with traditional irrigation. On plant growth performance, the sprinkler irrigation was better than furrow irrigation. Reducing supply of water, Kennebec, TNG No.1 were inhibited the growth performance such as plant height, leaf number, and stem diameter, but TSS No.4 could still maintain the growth performance. The yield data of different treatments were continued still collecting.
