Description

Technical Field

[0001] The utility model relates to the field of potted blueberry related products, in particular to a blueberry irrigation device suitable for small-scale greenhouses. Background Art

[0002] Blueberries generally prefer moist soil, but some varieties are drought- and cold-tolerant. Blueberries prefer acidic soil and have the lowest soil pH requirements of all fruit trees, requiring a soil pH of around 4.3 to 5.5. Cultivating in soil with an excessively high pH can cause iron deficiency and chlorosis, while low acidity can easily lead to magnesium poisoning. The soil should be loose, generally containing 8 to 12% organic matter. The ideal soil type is loose, aerated, moist, and high in organic matter, strongly acidic sandy loam or straw-carbon soil. Blueberries have slow-growing, slender roots that cannot penetrate the clay layer in heavy soils, resulting in poor growth. Low organic matter and poor drainage can also lead to poor growth. Blueberries can only grow normally in soils with an organic matter content greater than 7%.

[0003] Blueberries are sensitive to water shortages, preferring moisture, having poor drought tolerance, and are susceptible to waterlogging. Irrigation water requirements also vary across the growing season. Maintaining optimal water conditions during the vegetative growth phase promotes plant growth. However, during the fruit development phase and before fruit ripening, water supply should be appropriately reduced to prevent excessive vegetative growth from competing with the fruit for nutrients. After harvest, optimal water supply should be restored to promote vegetative growth. Reduce water supply from mid-autumn to late autumn to facilitate a timely onset of dormancy. Young orchards should maintain an optimal soil moisture content of 60% to 70%. Mature orchards and those in peak fruiting stages should reduce water supply during the fruit development phase and before fruit ripening, keeping soil moisture around 50%. After harvest, restore optimal water supply, returning the orchard to a water content of 60% to 70%. Reduce water supply from mid-autumn to late autumn to control it to around 50% to facilitate a timely onset of dormancy.

[0004] During the growth cycle of blueberries, the water quality requirements are relatively high, because blueberries like to grow in acidic soil. If deep well water, which has a high pH value and high sodium and calcium ion content, is used for irrigation for a long time, it will seriously affect the growth, development and yield of blueberries.

[0005] As farmers gain a better understanding of blueberry growth habits, they are gradually incorporating new technologies into their production processes. Large-scale greenhouse blueberry cultivation utilizes water treatment equipment and fertilizer mixing equipment to regulate water quality and fertilizer concentration, but these systems are relatively expensive. Small-scale greenhouse farmers currently lack comprehensive automated irrigation and fertilization systems. Utility Model Content

[0010] Preferably, the openings on the tray are arranged in a rectangular array.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] This irrigation device, suitable for small-scale greenhouse blueberry production, installs a pre-filter on the water inlet pipe. The pre-filter type can be adjusted based on the water source. The filtered clean water is then fed into a water storage tank, where fertilizer solution is prepared. A first integrated pH / EC sensor is also placed in the tank to monitor fertilizer solution data. The prepared fertilizer is pressurized by a booster pump on the irrigation main pipe, then filtered through a secondary automatic backwash filter before being fed into the field irrigation network. The irrigation area is adjusted by controlling a field solenoid valve. Drip irrigation heads are used in the field to ensure that fertilizer water drips directly onto the crop roots, improving fertilizer and water utilization efficiency.

[0013] This blueberry irrigation device, suitable for small-scale greenhouses, supports two adjacent planting pots by placing a tray under them. The return liquid flows through openings on the tray into a return liquid collection tank below. A second integrated pH / EC sensor is installed in the return liquid collection tank. By comparing the difference between the return liquid and the original liquid, the degree of fertilizer absorption is determined, providing data support for adjusting the fertilizer ratio.

[0014] This blueberry irrigation device, suitable for small-scale greenhouses, determines whether the stock solution ratio is reasonable by comparing the properties of the stock solution and the return solution, and determines whether the blueberries need irrigation by comparing the amounts of the stock solution and the return solution, thereby guiding farmers to carry out irrigation and fertilization. It can irrigate according to the growth conditions of the blueberries to avoid wasting water and fertilizer. While reducing manual operations, it provides data support for fertilizer ratio, thereby achieving the goals of saving labor, water, and fertilizer, increasing production, and improving quality.
