Scientific irrigation needs to consider the timeliness, appropriateness, reliability, effectiveness, and uniformity of irrigation. It is an important guarantee for stable and high yield of crops, which can achieve the goal of water conservation and yield increase, promote the development of agriculture, and increase the economic income of farmers.
Jinan Xinxing Water saving Irrigation Equipment Co., Ltd. is mainly engaged in the sales of PVC/PE plastic pipes, fittings, sprinkler irrigation, micro spray, drip irrigation, infiltration irrigation, filtration and fertilization systems and other water-saving irrigation equipment. Below, the editor of Jinan Xinxing Water saving Irrigation Equipment Co., Ltd. will specifically explain how to scientifically irrigate crops?
1. Timeliness of irrigation
It refers to the timely level of irrigation and water distribution in the irrigation system. Timely water supply to crops is an important prerequisite for increasing crop yield and income, and is also one of the important measures to save water resources. When crops require irrigation, the pipeline system should promptly deliver the irrigation water to the field to meet the water requirements of the crops.
2. Appropriateness of irrigation
It refers to the irrigation system being able to obtain an appropriate amount of water when crops need it, neither too much water can cause leakage losses and deterioration of crop growth environment, nor too little water can meet the water requirements of crops, leading to crop wilting.
3. Irrigation reliability
It refers to the reliability of the irrigation system in ensuring the use of water for crops in the irrigation area. It can be expressed as the ratio of actual irrigation area to expected irrigation area, or as the ratio of the amount of water needed per unit area during the crop growth season to the amount of water that the irrigation system can provide.
4. Irrigation effectiveness
It includes various aspects, including the ability of the pipeline network to effectively deliver water to the fields and minimize water loss during the water transmission and distribution process, as well as the ability of crop roots to absorb irrigation water as much as possible and minimize water evaporation loss. At the same time, it also includes the degree of effective utilization of rainfall, which is reflected in the increase of crop yield or economic income. In arid and water scarce areas, managers need to understand the water requirements of various crops at each growth stage, establish an economically reasonable irrigation system, optimize the allocation of limited irrigation water, and achieve higher crop yields.
5. Irrigation uniformity
It refers to the uniformity of flow rate in various levels of water transmission and distribution pipelines during the irrigation season, as well as the uniformity of water distribution in the field. High uniformity of irrigation can reduce leakage losses, achieve water-saving goals, and thus achieve the effect of increasing yield and income, and improving crop quality.
