Five New Technologies for Irrigation in Foreign Orchards

1 Automatic irrigation

       This technology was invented by the French National Institute of Agronomy. They developed an automatic irrigation device, that is, in the fruit branch and other parts, placed some special "tentacles" to test the crop of subtle changes. When the crop can not get water from the soil, must consume its own water in the branch, the branch will appear signs of shape reduction, "tentacles" can immediately be translated into a signal to the computer, the computer will start the irrigation device, irrigation.

2 Negative differential pressure irrigation

       This technology was invented by Japan. A porous pipe is buried underground in the orchard, and the negative pressure difference between the water in the pipe and the surrounding soil is used for automatic irrigation. The whole system can automatically adjust the amount of water according to the dryness and wetness of the soil around the pipe, so that the soil humidity is maintained at the most suitable state for the growth of fruit trees.

3 Ground infiltration irrigation

       This technology was invented by Japan. When irrigating, the soil automatically absorbs water from the water content system emitter set up by the suction of capillary tubes. When the water content reaches saturation level, the water containing system emitter automatically stops supplying water. Since the flow rate of the system water-bearing emitter is only 0.01g/s, the salt cannot exist in a solution state, and the infiltrated area of the soil becomes desalinated fresh water. Therefore, it is possible to irrigate with saline water without damaging the soil using this system.

4 Irrigation by irrigation pipes on sloping land

       This technology was invented by Russia. The tube length is 150~200m, the diameter of the tube is 145mm, and the sections of the tube are connected with the reducer method to ensure the uniform flow out of each section of the orifice, so that the water flows from the tube orifice into the irrigation ditch on the slope.

5 Soil net irrigation

       This technology was invented by Austria. A glass fiber net containing semiconductor material buried in the roots of fruit trees is the negative pole, and a plate made of graphite, iron and silicon buried in the deep soil is the positive pole. When the fruit tree needs water, as long as the net is fed with electric current, the water in the deep soil will flow from the positive pole to the negative pole under the action of electric current, and thus be absorbed and used by the fruit tree.
