Smart weather station with iMetos technology attached to the automatic irrigation system of Mr. Dinh Phuc Tien’s family (Dong Tra village, Huong Tra commune, Huong Khe) Applying 4.0 technology in production and management In 2017, with the support of the Ministry of Science and Technology, Mr. Dinh Phuc Tien (Dong Tra village, Huong Tra commune, Huong Khe), invested 150 million VND to install iMetos smart weather station and system Automatic irrigation system to serve production at home garden (specializing in seedling nursery). This is a system that can forecast rainfall and rain time, alarm over-threshold rainfall, extreme temperatures such as hot, cold, cold, harmful cold, hoarfrost… with a service range of 5-20km. “Since the application of a weather forecast system combined with an automatic irrigation system, irrigation work is more active, the quality of seedlings is high, bringing more economic efficiency. Revenue from garden economic production in the past 5 years has averaged 1.2 – 1.5 billion VND/year. And this is also the model garden that won a special prize in the contest of model residential areas and provincial gardens in 2017 “- Mr. Dinh Phuc Tien said. Many gardeners and orange farms in Ha Tinh province have made traceability by electronic stamps. Many agricultural products from gardeners and farms such as: Phuc Trach pomelo; oranges: Khe May, Thuong Loc, Son Mai; Huong Son deer velvet and OCOP products in Ha Tinh province have been stamped with QR codes for traceability. From there, goods are easily connected to e-commerce trading floors and are available at many supermarkets. The application of scientific and technical progress to production is one of the five criteria for model gardens under criterion 20 (model residential area, model garden). This is a breakthrough, creative way of Ha Tinh, creating attraction and spread of technology application in production development and construction of new rural areas. By the end of 2020, Ha Tinh has over 600 standard model residential areas and over 6,000 standard gardens.

Leaders of Ha Tinh NTM Coordination Office worked with KYC Solution Joint Stock Company to deploy digital transformation software, build smart NTM residential areas, smart NTM communes. Through digital models to help people manage the product production process. This is also an open forum for people to provide information, quantity of products to connect the market, promote products… People can easily access and learn knowledge in economic development of household gardens, education. education, health care…, step by step actively participate in the goal of the national digital transformation program. “We highly appreciate Ha Tinh as being proactive and taking the lead in implementing digital transformation in building new homes according to the requirements of national digital transformation as well as of the Central NTM Office… in order to promote the digital process. modernization and application of information technology and digital technology in new rural construction; to step up the application of information technology and digital technology in order to fundamentally change the management, administration and supervision of government agencies at all levels, especially at the commune level, production and business activities of enterprises. , cooperatives, especially in the OCOP program, … contribute to bringing the quality of new rural construction into depth and sustainability, towards smart rural areas… in the period of 2021-2025” – Chief of Coordination Office Central NTM Nguyen Minh Tien affirmed.

The provincial Ha Tinh there are more than 7,000 ha of citrus trees, of which orange and pomelo trees account for nearly 90%. The most cultivated area for pomelo trees is in Phuc Trach, Huong Trach and Huong Do communes (Huong Khe district), while the orange area is mainly concentrated in Vu Quang district up to 2,500ha, Thuong Loc commune (Cam Loc district) is 240 ha.

Land for planting oranges and pomelo This area belongs to the group of red and yellow feralit soil and an area of ​​basalt soil formed on hilly or mountainous terrain interspersed with high mountains, very hot summer climate, on average 380C, cold winters and rainfall. Large, suitable for grapefruit, orange trees.

However, in the agronomy of pomelo and oranges, there are many limitations due to the unscientific use of fertilizers, farmers rarely invest in organic fertilizers, use too much acidic chemical fertilizers such as supe, phosphorus, nitrogen, etc. or types of fast-soluble NPK containing acid root for fertilization, intercropping legumes for land investment is limited, and in the rainy season, soil is very large.

As a perennial tree, pomelos and oranges in Ha Tinh lack nutrition and sour environment, thus reducing productivity, appearing harmful pests and diseases. Before 2010, the brand name of Phuc Thach pomelo and oranges in the market was faint. The area of ​​orange cultivation has narrowed, the gardeners’ income has decreased sharply … in order to restore the brand, regain productivity and quality, Ha Tinh province has focused on investing in building a fertilization process according to the VietGAP standards.

Understanding local needs and shortcomings in the use of fertilizers by farmers, Van Dien Fused Phosphate Joint Stock Company cooperates with Ha Tinh Gardening Association to deploy many models. using Van Dien fertilizer for pomelos, oranges and safe vegetables on the table in Huong Khe, Vu Quang, Duc Tho …

Trial on Van Dien fertilizer in pomelo production areas of Phuc Trach, Cam Khe May, Thuong Loc, Cam Bu Huong Son.

The experiment was conducted in a closed crop year 2010 on 1.5 ha of 15 year old grapefruit in Phuc Trach, together with 2.0 ha of 10 year old oranges in Khe May and Huong Son by using completely Van Dien fertilizer including Fused phosphate fertilizer and NPK multi-factor fertilizer is used specifically for citrus. Van Dien fertilizer divided fertilizer 4 times a year:

• Stage 1: Applying after harvesting, using 1.5 – 2.0 kg / root of Van Dien fused phosphate + multi-element of NPK 5.10.3, from 2- 4 kg + 15 kg of decomposed organic fertilizer /origin.

Phase 2: Applying flowers with the amount of fertilizer from 1.0 -1.5 kg / root of ĐYT NPK 12.5.10.

Stage 3: Applying after fruiting from 2.0 to 3.0 kg / root of health care NPK 12.8.12

• Phase 4 fertilizing 50 days before harvesting fruit from 1.5 -3.0 kg / root ĐYT NPK 12.7.20.

Grapefruit fertilized with Van Dien is more prominent than the control along with other NPK fertilizers in that: Bright green leaves, shiny leaf surface, thick leaves, smooth bark and branches, 50% reduction of harmful pests and diseases. high fruiting, fruit uniformity, concentrated ripening, beautiful peel color, less fruit drop, yield 1.8 times higher than control, sweet and fragrant quality characteristic of Phuc Trach grapefruit and famous Buu before. After only 10 years, farmers have liked the effectiveness of Van Dien Fertilizer

Mr. Nguyen Xuan Tinh – Chairman of the Gardening Association of Ha Tinh province said, “Since the introduction of Van Dien fertilizer, orange trees, grapefruit trees here are fully supplemented with nutrients, healthy plants, good growth and development. With high yield and quality, up to now, Ha Tinh province has thousands of hectares of citrus trees fertilized with Van Dien fertilizer ”.

Mr. Hoang Van Giam, Phuc Trach commune, Huong Khe district, said: “My family has 200 grapefruit roots 10 years old, in the last 6 years, I completely use Van Dien fertilizer, every year grapefruit has good season to sell. After fertilizing a healthy grapefruit tree, wrong flowering, large fruiting, uniformly large fruit, less drop, reducing pests, yield, high quality, Van Dien fertilizer contains much more nutrients than other types. Fertilizer is currently on the market, in Phuc Trach most people use Van Dien fertilizer.

Ms. Pham Thi Lanh, who has 500 oranges and is 13 years old, commented: “Van Dien fertilizer with good quality, competitive price, convenient supply, easy to use, high efficiency, great profit. More than 7 cases of oranges in the family completely use Van Dien fertilizer, the most difference is the color of the leaves, the shade is visible from a distance, dark green, after heavy rains, the trees are very few to drop fruit, the stools are good and durable. , good quality, high productivity, high quality, easy to consume, especially less using plant protection drugs, safe for users, protecting the environment ”.

In the Buu orange growing area in Son Mai, Son Thuy, Son Truong communes with more than 1,000 hectares, Mr. Ngo Xuan Hoa, Son Mai commune, cultivating 300 orange trees, shared: “The family has tested many fertilizers for orange trees, but Only Van Dien fertilizer is suitable and easy to use fertilizer.
