Irrigation is the process of storing water in the soil or other growing substrates for plants to grow in the future.

Scientific irrigation is an important guarantee to promote the stable and high yield of crops, the sustainable development of agriculture and the increase of farmers’ income. Scientific irrigation includes four characteristics: timeliness, appropriateness, reliability and uniformity.

1. Irrigation Timeliness

Agricultural crops as organisms, its growth process has its own laws, the timeliness of irrigation system means that irrigation measures should follow the law of crop growth, when the crop growth needs water and fertilizer, the center pivot or linear translation irrigation machine should operate efficiently, supply enough water and fertilizer to ensure the water demand of crop growth, maturity and fruit.

2. Irrigation Appropriateness

The right amount of irrigation refers to the establishment of an economical and reasonable irrigation system according to the local precipitation, soil water content, water evaporation, and crop water demand indicators, and the irrigation water of the center pivot or linear translation irrigation machine should be scientifically set, neither too much nor too little. Too much water will cause leakage losses and crop

growth environment deterioration; Too little water, so that the irrigation water can not meet the water requirements of crops, resulting in crop wilting.

3. Irrigation Reliability

Irrigation reliability refers to the selection of high-quality center-pivot, linear translation irrigation machine, the selection of sufficient water sources, to ensure that there is water available, there is a machine available, and the operation is good.

4. Irrigation Uniformity

Refers to the uniformity of the flow of water pipelines at all levels and the uniformity of the distribution of water in the field during the irrigation season. Higher irrigation uniformity can reduce leakage losses, achieve the purpose of water saving, and then achieve the effect of increasing production and income and improving crop quality.
