Suitable watering method of blueberry in greenhouse

1. Specific watering method of blueberry: Drip irrigation system generally consists of four parts: water source, head hub, water pipeline system and emitter. Its water pipeline system adopts fixed system according to the arrangement of capillary in the field. The specific setting method is as follows: underground water pipeline: the water pipeline system includes main pipe, branch pipe and capillary. All pipelines must be buried below 30 cm underground. Design the underground pipeline according to the terrain, and reserve the above-ground station pipe according to the size and terrain of the plot. Generally, it should be located in the middle of the plot, with the filter and valve buried shallowly, and the drain valve left in the position of the drainage ditch.

2. Laying capillary: laying capillary on both sides of the plant, with the distance from each side to the plant 15cm, and the length of capillary not exceeding 100m, preferably around 75 m ... The tightness of laying depends on the season, which can be moderate in spring and autumn and slightly loose in summer. Capillary laying is best carried out before seedling raising, and at the latest at the same time with seedling raising.

3. Installation of the emitter: Install the emitter immediately after the seedlings are planted for timely irrigation. Usually, each factory is equipped with 4 transmitters. The drippers are placed on the wool pipes on both sides of the plant, and two drippers are installed on each side, about 30cm apart. Pay attention to the position of two drippers on each side, and the plants are on the diagonal of the four drippers.
