What issues should we be aware of when using an intelligent water and fertilizer integrated system?

UsingIntelligent Water and Fertilizer IntegrationSystem, what issues should we pay attention to? Let's find out! Water and fertilizer integration utilizes a pipeline irrigation system to dissolve fertilizer in water, simultaneously carrying out irrigation and fertilization, timely and appropriately meeting the crop's water and nutrient needs, achieving synchronous water and fertilizer management and efficient utilization of water-saving agricultural technology. Through a controllable water supply pipeline system, fertilizer, and compatibility, water is delivered through pipes and drippers in a drip irrigation format, uniformly, regularly, and quantitatively penetrating the crop root system's growth and development, ensuring the main roots in the soil remain loose and appropriately moist.

Based on the characteristics of different crop fertilizers, soil environment, and soil nutrient content; the system designs the water and fertilizer needs for different growth stages and provides water and nutrients to crops proportionally, on a timed and quantitative basis. The intelligent water and fertilizer integrated management system can conveniently and efficiently achieve automated integrated water and fertilizer management, thus gaining recognition and favor from agricultural practitioners. Importantly, it manages the combination of water and fertilizer. What issues should be noted when using an intelligent water and fertilizer integrated system?

First, pay attention to daily maintenance! The water and fertilizer integration system requires meticulous maintenance to achieve optimal performance. At the end of each irrigation season, a thorough inspection and maintenance of the pipelines is necessary. Flush the buried pipes and empty the water, cleaning and covering the primary equipment.

Second, pay attention to filter protection! Commonly used filters include centrifugal filters, screen filters, stacked filters, and gravel filters. The filters inside should be regularly checked, and any damage should be promptly repaired or replaced. At the end of the irrigation season, the filter cartridges should be removed and rinsed for reuse. Automatic cleaning: Frequently flush valves, checking for blockages. Manual cleaning: Loosen the screws, open the pressure cover, remove the filter element, and clean the filter mesh with a brush.

Third, prevent excessive irrigation during drip irrigation! Drip irrigation only irrigates the root system and applies fertilizer. Therefore, it is necessary to understand the depth of the fruit tree root system distribution. A simple method is to use a putty knife to dig up the roots and see how wet they are, which can then determine whether there is excessive irrigation. Perhaps a tensiometer could be installed underground to monitor the irrigation depth.

Fourth, reasonably control the fertilizer concentration! Many fertilizers are inorganic salts. When the concentration is too high, it can "burn" the leaves or roots. The concentration must be controlled when spraying or drip-irrigating fertilizer through the irrigation system. A precise method is to measure the conductivity of the fertilizer applied from the drippers or outlet. Generally, a range of 1.0-3.0 ms/cm is safe. Perhaps diluting water-soluble fertilizers 400-1000 times, or using 1-3 kg of water-soluble compound fertilizer per cubic meter of water for spraying, is safe. In drip irrigation, the soil buffering effect may slightly increase or not significantly affect the drip irrigation concentration. But you cannot ignore the following points:

Fertilizer solubility: The irrigation channels in integrated water and fertilizer systems are small and easily clogged. Generally, compound fertilizers have many insoluble nutrients and impurities, easily clogging the filtration system. Therefore, water-soluble fertilizers with high solubility and comprehensive nutrition are recommended for water and fertilizer integration. Fertilizer formulation: Different crops require different amounts of fertilizer. Even for the same crop, different amounts of the same elements are needed at different growth stages. Therefore, we need to match the nutrient elements according to the actual needs of the crop at each growth stage.

Secondary dissolution of water-soluble fertilizers: Although the dissolution rate of water-soluble fertilizers is high, the dissolution rate is relatively low. Therefore, continuous stirring is needed during the dissolution process to accelerate the dissolution rate. Sometimes, for convenience, water-soluble fertilizers are directly added to the tank or Enter the tank without being completely dissolved, assuming that the tank volume is large enough to dissolve it. In fact, there is usually a layer of white precipitate at the bottom of the tank. Before pouring the fertilizer into the tank, the water-soluble fertilizer should be completely dissolved in a container and then poured into the tank.
