First, if you want to increase your income, the tube must be recycled.
"The corn in this demonstration field is gratifying, the tassels are big and full, and I bet that the output will not be low!" The villagers of Lianzeng Village, Hangtouqiao Town, Hangjinhou, Inner Mongolia, Bayernor, are watching agricultural technicians drip irrigation and fertilizer Integrated corn planting area for production measurement. “After measuring the output of experts, the average yield of water and fertilizer integrated corn is 1118 kg per mu, which can not only increase production by 203 kg, but also save 50% of water, 30% of fertilizer and 80% of labor, so that one mu of land can be increased. Around 330 yuan." Wei Yuhai, director of the Agricultural Technology Promotion Center of the flag, announced the results of the production to the surrounding farmers.
"Water and fertilizer integration has both increased production and increased income. We like it very much, but we are using it for the first year. When the corn is taken back from the house, how can it be cleaned up? Can this drip irrigation be used next year? The shovel (the first part) of the well house does not need to be dismantled?" Yuan Shuangxi, a villager in the village, told the author about the doubts in his heart.
The drip irrigation belt (tube) is the end pipe network of the drip irrigation system and is an important part of the water and fertilizer integrated system to transport water and fertilizer to the crop. “Drip irrigation belts mainly include labyrinth drip irrigation belts and inner panel types. The labyrinth type is mainly used in Daejeon. The service life is generally 1 year; the inner panel is mainly used in facility agriculture, and the quality is better and the price is higher. Generally, it can be used for 3-5 years.†Baiyunlong, a technician at the Inner Mongolia Soil and Fertilizer Station, said that the drip irrigation belt in facility agriculture is easy to recycle after use, and can be directly used twice. It is difficult to recycle the drip irrigation belt in Daejeon. Basically, it cannot be used directly again. The drip irrigation belt that cannot be used twice must be recycled in time and properly disposed of. It should not be directly discarded in the farmland, and it should not be incinerated to avoid polluting the environment.
The original home of Duan Road, Bayingbaoli Town, Bayanmuer City, has a total of 200 mu of land. All of them use the integration of water and fertilizer under drip irrigation. He is not worried about the recycling of drip irrigation belt. “The old drip irrigation belt can be sold. It can be sold from the ground to the recycling point. It can be sold or exchanged for a new one. The recycling point mentioned by Duan Luyuan is actually a local drip irrigation belt recycling factory. It mainly recycles the labyrinth drip tape used in Daejeon, recycles it and then granulates it, adds new material, and manufactures a new drip tape. The old paragraph also calculated the economic account with the author, the old drip irrigation belt of one mu of land can be sold to the recycling point for about 70 yuan, and the new drip irrigation belt is 120 yuan per mu, so that the new investment of 50 yuan per year can be Continue to use drip irrigation, and the production cost has dropped a lot.
Second, if you want to use drip irrigation well, the first part must be well maintained.
The first part of the drip irrigation water and fertilizer integrated equipment generally includes pumps, filtration equipment, fertilizing equipment, etc., which is the core part of the whole system. “The first part is the heart of the integration of drip irrigation and water and fertilizer. If there is a problem with the pump, the water supply will be insufficient. If there is a problem with the filtration, the pipe network will be blocked and the fertilization problem will be nutritionally unbalanced.†Wang Jian of the Urad Front Banner Agricultural Technology Center in Bayannaoer City is working. In the well room, explain to the farmers the main points of the drip irrigation first maintenance.
The first is the water pump. After the last irrigation, clean the surface water stains in time to prevent rust and replace the lubricating oil or butter. After the engine is lubricated for 1000 hours, the bearing and the bearing body cavity should be cleaned in time. Replace the lubricating oil; if it is lubricated with butter, grease the motor bearing in time. If the centrifugal pump is operated for more than 2000 hours, all parts should be disassembled and inspected, cleaned and descaled, repaired or replaced with damaged parts, and replaced if necessary. The overhaul period of the unit is generally one year.
Secondly, the filtering equipment, the filter of the net filter is relatively easy to block and damage. After the end of autumn use, the filter should be taken out in time, cleaned, and the iron filter must be rust-proof; centrifugal filter After use, open the sand discharge port in time, flush the sand and prevent the blockage; after using the laminated filter, open the outer casing, remove the laminated piece and clean it, and dry the sealing ring in the plastic case with a dry cloth. Go back, then open the plug of the bottom sand shovel and drain the deposit.
After that, it is a fertilizing equipment and an iron pressure difference fertilization tank. It is necessary to clean and control the moisture in time to prevent corrosion and avoid rusting the pipeline in the coming year. The plastic fertilizer barrel should be cleaned in time and placed in a cool and dry place indoors to prevent oxidation. The body is damaged; the fertilizer pump should be cleaned in time and replaced with oil. The iron parts in the entire head should be disassembled, washed, dried and rust-proof as much as possible to avoid affecting the second year of use. In addition, the pipe network system should also do a good job of cleaning, first open a number of round irrigation group valves (less than the number of normal wheel irrigation valves), then turn on the water pump, then open the main pipe and the end pipe end plugs in turn, high pressure flushing, open the underground after completion At the end of the pipeline, the water is discharged from the pipeline to prevent freezing and cracking of the pipeline in winter. The parts that can be removed in the pipe network should be disassembled as much as possible, and washed and stored in the warehouse.
The maintenance and maintenance of the drip irrigation head requires certain technical experience and professional knowledge. It is usually carried out by a fixed management personnel. Complex equipment such as pumps and fertilisers must be dismantled and maintained by professionals.
Third, in order to maintain the provincial matter, scientific design can not be less
At present, most of the farmers have accepted the investment of drip irrigation pipes, water-soluble fertilizers and other materials added to the technology of drip irrigation water and fertilizer integration under the film, but there are still some problems in equipment maintenance.
“Drip irrigation is very good, but we don’t worry about it!†Liu Jianzhong, a villager from Shuanghe Town, Linhe District, Bayannaoer, complained to the author. Originally, in order to use drip irrigation, he contacted several neighboring farmers to raise a drip irrigation equipment in a fund-raising manner and funded according to the cultivated land area. However, due to the different arable land area, different land levels, different planting crops, etc., the area of ​​the wheel irrigation area is uneven, and problems such as pipe bursting and running water, running fertilizer, etc. occur frequently, and it is very troublesome to maintain.
"If you want to use water and fertilizer integration to save your mind and worry, you must first plan and design rationally, and then establish equipment use and maintenance system, so as to avoid equipment failure." According to Zhang Zhizhong, director of Bayannaoer Agricultural Technology Center Datian's production environment is complex. When developing water and fertilizer integration, it must be adapted to local conditions and rationally planned. It is necessary to comprehensively consider factors such as water source, topography and crops, and plan and design scientifically and rationally, which is not only convenient to use but also reduces maintenance costs. Therefore, in the design, remember not to blindly follow the trend, to find professional technical personnel to conduct on-the-spot survey and design, and then construction, so as to minimize the investment in post-maintenance.
