28/03/2015
Cost savings of 70 million / year, water-saving irrigation, productivity increased by 10%, to ensure safety during use ... It is effectively brought after 3 years from the garden of his dragon Vo Ngoc Diep (Diep Friday), head of cooperation (THT) dragon Phu Luong (Luong Phu C, Luong Hoa Lac, Cho Gao, Tien Giang) is Mono Energy company (Australia) investment drip irrigation system by solar energy.
Mr Yip said that 3 years ago, after visiting his garden dragon, Australian tourist group (under Mono Ennergy company) offered to test the system installed drip irrigation using solar energy for his garden. Then, do not know how effective but not expensive realized investment so he accepted the invitation.

After installation, commissioning, drip irrigation system using solar energy is effective beyond his expectations. Because the roots are given a sufficient amount of water helped to thoroughly absorb the fertilizer plant to grow green dragon. Using this system, he has helped to save the cost of hiring labor and electricity costs (about 6 million / month), while the dragon fruit orchards yield increased to 10%.
Drip irrigation system using solar energy rather simple structure, comprising: a panel (mounted battery system and motherboard) to collect solar energy (photovoltaic turned into electricity); control box (to be played with 2 panel with electrical conductor) composed of 1 button lights and the selected voltage level (including 5 DC voltage levels: 180, 144, 108, 72 and 36 Vol) to supply power to operate the motors. Pump system is operated by an electric motor 3 phase capacity 750w (1 HP or 1 horsepower) and plumbing systems to the original dragon.
Each stem is inserted 2 dragon irrigate valve (providing about 1 hour per liter of water), irrigation time from 6-7 hours / day, 3 days old way 1 times. The process of saving irrigation water infiltration, water penetrates, thereby helping to improve productivity, efficiency and significant cost savings. According to Michelle, over 3 years of use, this system still works fine, no problem; special time of the day sun as much as possible.
's Park Diep dragon with an area of 1 ha with about 1,200 offices (mostly white flesh and a few dozen original red flesh). In 2013, he harvested 25 tons, sold for an average of 25 thousand VND / kg, except for expenses, he collected $ 250 million in interest. Compared with previous investments drip irrigation system has helped him earn 110 million per year, including 70 million saving on labor costs, electricity costs and increased income by over 30 million dragon fruit yield increased by 10%.
Mr Yip said tht dragon Phu Luong currently has 15 members, about 10 hectares of arable dragon (the most common newly issued standards VietGAP) provides for the export market. The members intend to invest drip irrigation system using solar energy as he found the practical effects brought by this system.
However, because investment costs are quite large (about 100 million), some members also are considering funding. "Suggested State, the banking industry has supported policies or loans with preferential interest rates to help growers dragon and conditions apply gradual scaling model for a number of other local" - Diep proposal.

Automatic watering system for plants dragon
Binh Thuan market appears some kind of products catering to the irrigation system dedicated automatic and semi-automatic dragon tree originated from Israel, the United States.
Anh Nguyen Cong Cuong, Director, Trading Company Ltd - DV Nguyen Cuong, the main distributor of specialized products for irrigation, said: dragon chances are entering the U.S. market, in order to do this, farmers need to ensure planting dragon towards clean, safe, can achieve some difficulties as VietGap standards, including technical Eurogap ... watering and fertilizing in accordance dragon will be one of the criteria even contribute to a safe tree development and achieve the highest efficiency. Farmers planted in Israel knew from a very early dragon, therefore experts in this country has designed and produced a special irrigation system is automated to cater to modern irrigation, fertilization dragon tree, crop farmers and professional effectiveness.
The great dragon farm or farmers and fruit production scale, can invest in dedicated irrigation system automatic and semi-automatic to cater for irrigation and fertilizer in accordance with the volume requirements. He said Cuong, when the unit needs to install the irrigation system dedicated, professional company will have to take place for installation, consulting and warranty, maintenance entire irrigation system. Installation costs have dedicated irrigation rates range from 45-48 million. Using this irrigation system, dragon fruit growers will reduce labor costs, save time and power consumption when watering the garden dragon.
Whereas farmers irrigate with dragon craft measures will take a lot of time and ensure enough water and fertilizer needed for crops (if not enough trees watered too little water, too much is and distribution of water will spill out of the tree, not effective). "On average a 1 when watering handmade dragon head with about 1 minute of time, so that watering will not ensure that all of the water dragon pillars on the right" golden hour "(early morning and late afternoon ), to help the plants grow in a better way "- he said Cuong.
When using automatic irrigation systems or semi-automatic, with a drip nozzle fitted with a water filter and automatic dosing system, can control the amount of fertilizer and water without human intervention will help for agricultural crops in general and in particular of fruit tree fertilizer and water penetrates quickly and correctly quantify the most. Within 2 hours, the system can be approximately 2 ha irrigated crops, ensuring timely watering appropriately, the best help plant photosynthesis. Currently Nguyen Cuong Company began assembly deployment irrigation system dedicated to a number of businesses, large dragon establishments in the province of Binh Thuan.
