Drip irrigation belt facilities and supporting technologies under the application of strawberry membrane

1. Drip irrigation belt facilities.

1. Drip irrigation belt equipment specifications:

The micro-irrigation belt is 25mm in diameter, with double discharge holes every 25cm, and the water pipe is 40mm in diameter.

2. Drip irrigation equipment and connection:

Drip irrigation equipment consists of drip irrigation belt, water pipe, fertilizer applicator and special joint.Special connector is used for connecting micro-irrigation belt with water pipe;The fertilizer applicator is used to top the strawberry with water when filling water.Install fertilizer applicator between water source and main pipe, install joint and connect micro-irrigation belt.A micro-irrigation belt supplies two rows of strawberries simultaneously.No suspension larger than 0.8 mm in diameter shall be allowed in the water source.

3. Technical process:

Small water pump + connector + filter + main, dry, branch pipe + drip irrigation belt + fertilizer applicator – installation – commissioning – operation – management and maintenance.

Ii. Supporting technologies.

1. Make high check:

It can be divided into two modes, xiao gao qi and big gao qi.Xiaogao beds were planted according to row spacing of 50 ~ 60 cm and plant spacing of 15 cm. The beds were 10 cm high and 40 cm wide. Each mu was planted with about 9000 seedlings.The drip irrigation belt is laid at the end perpendicular to the furrow, and the water pipe is laid between two rows of strawberries.When planting, the seedlings with more than 5 leaves should be selected, which should be planted with soil lump on cloudy days or after 4 p.m., without burying the heart or exposing the roots on the top, and the bow-back of the new stems should be outwards (the edges planted on the beds should be bow-back inward).After planting continuous drops of water, until the survival.

2. The effect of:

Mulch around mid-november.To further improve the water-saving effect of drip irrigation belt to prevent the decrease of ground temperature and moisture;Avoid air humidity too much, reduce the occurrence of gray mold, powdery mildew, root rot.

3. Principle of dripping water:

Follow the principle of “wet but not waterlogged, dry but not dry”.The relative humidity of soil is maintained at 50% ~ 60%.Strawberry roots 80% distribution from the surface down 15 cm of soil layer, topsoil is extremely easy to dry, so water should be a small number of times.
