The Mangyongdae Vegetable Farm in Mangyongdae District, Pyongyang, increases vegetable production.
“Our farm can be seen suitable for vegetable farming as it adjoins the Sunhwa River. We are paying special attention to greenhouse farming. We increase the production of such vegetables as cucumber, tomato, eggplant and red pepper by introducing good vegetable varieties,” said Kim Thae Hyon, chief engineer of the farm.
A noticeable thing is that the farm has proactively introduced latest research achievements.
A typical example is the application of effective low-association activated water generator.
The device is designed to convert the irrigation water into the low-association activated water with the help of electric impulse.
The activated water has reduced water molecules with hydrogen bonds and oxidation-reduction potential. It promotes the metabolism of vegetables, mitigates soil acidification and performs other different actions.
“The device has a big capacity for treating water, but consumes less electricity and is easy to install. We first applied it to a vegetable workteam on an experimental basis and observed the growth of vegetables according to their varieties,” said Kim Thae Hyon.
According to him, the growth condition of fruit vegetables has improved as they took roots and absorbed nutritive elements from soil better than before. And the fruits were so healthy that farmers have increased per-hectare yield by over 25 percent.
Based on such experience, the farm installed the device at a dozen pumping stations on the farm.
It also takes thorough measures for the prevention of damage by harmful insects by strengthening forecasting work and making effective use of agrochemicals.
“We acquire various technical knowledge related to vegetable cultivation at the agricultural sci-tech learning space of the farm. For example, the boiled and cooled water, water obtained by a high-speed centrifuge method or the water obtained from snow is effective in increasing vegetable yields. We also produce agrochemicals with liquid fertilizer and vegetable by-products,” said farmer Ri Kum Ok.
The farm has now finished the sowing of autumn bok choy on every field.
