The Wonhwa Farm in Phyongwon County is doing farming scientifically and technologically and to suit the regional characteristics.
“Our farm made thoroughgoing preparations from early January and pushed forward farming to gather good harvests this year without fail,” said Han Song I, chairwoman of the management board of the farm.
According to her, the farm directed primary efforts to resolving the problem of irrigation facilities for the stable and sustainable development of agricultural production.
Regarding the expansion of a waterway tunnel as an important issue from its experience and lesson drawn from last year’s farming, the farm expanded the waterway tunnel 2.5 times more than before at the beginning of this year and constructed an arched structure at a hundreds-of-metre-long waterway section. And it built a hundreds-of-metre-long channel for drawing water to the pumping station and laid Hume concrete pipes and built waterway structures at a tens-of-metre-long section to ensure a safe supply of water for hundreds of hectares of fields.
To increase per-hectare yield by more than one ton this year the farm strove to increase the fertility of soil.
It applied to all paddy and dry fields over 1.5 tons of silicon superphosphate per hectare and improved acid soil of two hundred hectares of dry fields by producing hundreds of tons of calcium hydroxide and applying more than one ton of it to the fields per hectare.
And it produced thousands of tons of hukposan fertilizer and applied more than five tons of it to all rice paddies and fields per hectare to increase their fertility.
“We are making a big effort to select and distribute varieties of paddy rice resistant to unfavourable meteorological and climatic conditions and introduce scientific and advanced farming methods,” said chief engineer Jang Chol San.
From the stage of growing rice seedlings the farm selected and distributed the best varieties whose superiority was already proved in practice and introduced scientific seedling growing methods to ensure an increase in per-hectare yield.
The methods include the method of treating seedlings in natural low temperature to grow full seedlings highly resistant to diseases while using less vinyl sheets and an advanced farming method based on water-saving technology to grow full seedlings with many stems so as to increase the yield.
Meanwhile, the farm is directing efforts to raising the proportion of work done by machines in farming.
It repaired tractors and rice-seedling transplanters in a qualitative way to finish rice-transplantation at the right time in the period of rice-seedling transplanting in spring and produced by itself and introduced deep-layer fertilizing machines to increase effectiveness of fertilizer and raise the efficiency over five times more than before. And it remodelled all rice combined threshers to make it possible to double the speed of threshing as compared to before.
Now the farm is accelerating the preparation for finishing harvesting and threshing qualitatively in time.
