What is the difference between different soil drip irrigation?

  Drip irrigation is the most effective water-saving irrigation method in drought-deficient areas, and the water utilization rate can reach 95%. Compared with sprinkler irrigation, drip irrigation has higher water-saving and yield-increasing effects, and can be combined with fertilization to increase fertilizer efficiency by more than one time. It can be applied to fruit trees, vegetables, cash crops and greenhouse irrigation, and can also be used for irrigation of field crops in dry and water-deficient areas. So what is the difference between different soil drip irrigation?

1. Sand land

    Generally, the water permeability of sand land is better than other land parcels, but the water and fertilizer loss of the water seepage is also serious. When drip irrigation of sand land, the underwater seepage speed is obviously faster than the lateral diffusion speed. If the fertilizer is added too early, it is easy to cause fertilizer loss, and the roots of the crop can not absorb nutrients, thus showing a series of symptoms of deficiency.

    Therefore, we recommend that for the well-seeded sand land, the fertilizer addition time is controlled at the end, leaving the tube for about half an hour to ensure that the fertilizer water is around the crop roots.

    Of course, there are also some special plots, sandy soils but poor water seepage, and fertilization time refers to clay ground.

    2, clay land

    The clay soil particles are small. When water is encountered, the fine particles are easy to block the pores of the soil, and the water permeability is poor, but the water retention and fertilizer retention are good.

    For such plots, it is recommended that fresh water be added to the crop line when adding fertilizer.

    Some of the surface soils of the plots appear to be more viscous, but the lower layers have more cracks and the water permeability is very good. Such plots refer to the sand fertilization time.

    3. Drip irrigation belt laying

    The wide-film three-belt or narrow-film double-belt plus fertilizer time is controlled several hours before the water is stopped, leaving the hair tube for about one hour.

    The wide-film double-belt plot suggests that the water should be added to the crop when it is fast.
