Large-scale greenhouse vegetable producers of the country are expanding their achievements in production through scientific manuring and cultivation.

A sea of fresh green vegetables is unfolding at the Sinuiju Combined Greenhouse Farm.

While channelling efforts into the regulation of temperature and humidity and nutrition management in keeping with the growth of crop varieties, it transplanted healthily-grown vegetable seedlings to greenhouse blocks and manured and cultivated them on a scientific and technological basis, thus reaping a good crop from the first harvest. Thanks to its researchers’ in-depth research into the cultivation technology for boosting productivity, there evenly grow such fruit and leaf vegetables as tomatoes and red peppers which can be harvested for more than eight months after being planted.

The Kangdong Combined Greenhouse Farm has also increased productivity by taking realistic steps to satisfactorily supply the citizens of the capital city with tasty and nutritious vegetables.

After establishing a system of recycling nutrient solution, the farm provided a solid guarantee for revitalizing production by increasing the rate of reuse while filtering and sterilizing used nutrient solution and adding necessary nutrient elements in a scientific and technological way. It built an agrochemical substitute production base in keeping with its actual situation to produce germicides, pyroligneous acid, etc. with raw materials abundant in the country, thus bringing in considerable profits. While putting much effort into manuring and cultivation based on such nutrition boosters as phytosine, it has made an effective use of greenhouse spaces by applying a box-type vegetable growing method and introduced a double cultivation method to suit the characteristics of crops, thus increasing output per unit area.

The Ryonpho Greenhouse Farm arranges the technical study and field passing-on-technique session on a regular basis to improve the employees’ technical knowledge and skills and ensured a timely supply of the liquid nutrient fertilizer to enhance productivity. In addition, it has carried out work in each process in a qualitative way, ranging from the treatment of seeds to gathering by raising the scientific level of production and business management, thereby growing a variety of fresh vegetables including cabbage and cucumber in large numbers.

The Jungphyong Greenhouse Farm has increased vegetable production 1.4 times as against the same period of last year by concentrating on the strengthening of technical forces.

While making an in-depth study of the global development trend as to the management and operation of greenhouses, the farm increases the cultivation area by putting in efforts to acclimatize new varieties of vegetables that are highly resistant to diseases and produce high yield. In particular, it introduced a device for automatically controlling ventilation windows according to the temperature required by crops and successfully updated the nutrition solution supply program, thus providing a guarantee for remarkably increasing vegetable production. And it set up a production base of efficient microbial agrochemicals and applied a nutrition booster rich in various microelements to further improve the quality of fruit vegetables and boost their yields. Employees of the farm grew functional vegetable seedlings healthily with a scientific cultivation method, properly controlled temperature and humidity and took precautionary steps to prevent damage from blights in a far-sighted way, thus achieving success in vegetable production.

Meanwhile, the greenhouse vegetable production units in Nampho Municipality have conducted manuring and cultivation scientifically and technologically to increase vegetable production 1.3 times as compared with the same period of last year.
