Coffee is now grown mainly in the Central Highlands region due to its suitability in climate and soil fertility. The main varieties are Robusta Coffee, Tea Coffee, and Jackfruit Coffee, which accounts for very little, mainly used as a graft base. The breeding of high-yielding coffee varieties such as TR4 coffee (coffee 138), TR9 coffee, short green coffee (TS5 coffee) … contributes to improving productivity and quality of Vietnamese coffee. much.
Currently, the state is encouraging households to use a drip irrigation system for coffee trees by helping crops increase productivity and especially the changing climate of Vietnam, causing bad weather and developing pests. strong. Drip irrigation of coffee plants is recommended for use by a stable water and water supply regime and incorporating the Novacid automatic fertilization system, so melon plants grow healthy, have less pests and produce extreme productivity. period is high but the cost is extremely low.
Below, Khang Thinh introduces the model: “Technology of dripping irrigation with water fertilization” for coffee plants. This model uses application control of drip irrigation to stimulate flowering under the supervision of managers and technical experts. The bloom results of this coffee garden will open up a viewpoint of Israel’s drip irrigation technology for coffee production development in Dak Lak in particular and Vietnam in general.
With this technology, water before leading to the coffee plant has been “passed” through a “central system” with the main components including electric pumps, water flow meters, pressure gauges, filters. discs, fertilizer filling systems, exhaust valves and complete central control mounting accessories. Water flow meter is used to accurately monitor the amount of irrigation water, check the flow of the pump; water pressure gauges are responsible for checking the operation of the pump, the cleanliness of the filter core and water leakage in the pipeline; the filter disc is responsible for removing residue, creating a stable water flow, relatively quality water before supplying to coffee; Air release valve for the purpose of releasing air pockets that form during irrigation generated by pump operation, terrain slope or irrigating water pipes having a uniform slope but too long ( 500m). The release of these air bags helps the drip irrigation system after starting to achieve pressure uniformity in the shortest time, preventing pressure differences caused by vacuum in the pipeline. affects the speed of water flow. The magnifier is the main feeding device and tube, delivering nutrition directly to the root zone of the plant through a drip tape.
The system of main and branch pipes, when installed, is buried 30cm to 50cm deep. Using a drip wire with a thickness of 0.38mm, operating pressure from 0.4 bar to 1.8 bar, which means fluctuating in the height from 4m to 18m, the flow of each drip tip is still the same (1.6 liters of water /hours). The drip piping system is arranged parallel to the two sides of the coffee root, about 70 cm from the root, buried about 5-7 cm from the ground; Thus, each coffee stump carries 12 dripping points (50 cm / 1 point apart).
The advantage of automatic drip irrigation technology is to bring water and nutrients directly to the active root zone of the coffee plant, through the self-compensating water pressure drip tip embedded in the PE pipe by the factory. , so that water and nutrition are provided sufficiently and evenly for all coffee trees in the garden, helping to manage irrigation water and coffee plants most effectively, especially for water regulation. suitable physiological blooming coffee flower (is the basis for deciding productivity, quality and sustainability of coffee gardens). This irrigation method is adapted to different conditions, so it can be widely used, especially for coffee trees in Dak Lak, a less flat land, a dry season lasts up to 6 months, always scarce water. .
Based on the amount of water needed to irrigate the coffee blossoming process that scientists have calculated on the basis of the physiology of the coffee plant during the flower bud differentiation period, Mr. My has irrigated the blooming into 2 the first time, the watering time is 15 hours, with the amount of water per 1 stem is 288 liters (12 drippers / coffee stub * 1.6 liters of water / drip tip / hour * 15 hours), after 9 days ( from the first watering phase) all buds have differentiated germination (reaching 70-80% of the amount of flower / crop). Fifteen days after the first wave, Mr. My watered the second round, the time was 7 hours with 134 liters of water / root (7 hours * 1.6 liters of water / hour * 12 drippers) had bloomed all different flower buds. rest. Compared to the previous sprinkler irrigation, the amount of irrigation water saved from 200-300 liters / root / time (because in the past, each overflow stimulated the blooming of coffee with water from 600-700 liters / root.
The system “drip irrigation combined with fertilizing through water” of Netafim – Israel is now improved compared to previous years such as: reducing the amount of water from the output in one hour of irrigation to suit the soil texture and love bridge of the coffee tree; overcome the phenomenon of the underground pipe system being bitten by insects; regulating the distance between the drip tip on the dropper is reasonable, the price is more suitable …. That creates conditions for producers to access drip irrigation technology more and more easily. According to Mr. Vu Kien Trung, Director of Khang Thinh Irrigation Technology Joint Stock Company, representative of Netafim Group (Israel) in Vietnam, the total investment cost for 01 hectare of drip irrigation combined with water fertilization for tomato current Israeli technology coffee is about 50 million VND / ha (some technical equipment can be replaced by high quality Vietnamese products); Minimum shelf life is 10 years.
This model helps to reduce the chemical leaching into the environment; limit soil erosion; make soil moisture evenly and consistently at the optimum level for coffee plants; make the fresh root area porous, increase the respiration capacity of the roots, increase the efficiency of absorption of water and nutrients of the plant, strongly develop the positive root mass; saving water for irrigation should be able to regulate the underground water of the drilled well, serving the coffee garden for adequate irrigation during the dry season; reduce a part of plant protection drugs because coffee plants grow well, are resistant to a number of pests and diseases, reduce labor …
