On january 24th, xinhua state, a journalist zhang wi, in a hut at the potato detoxification and production centre in gansu county, has a large, small and well-sequenced stream of potato seedlings that were planted on the ground with only dirt, and can now enjoy a “nutrient bath” in this modern “broomhouse”。
“the purpose of maximizing absorption can be achieved through the direct spraying of nutrient mist in the roots of potato seedlings through these nozzles after they have been deployed by professionals to produce nutrient fluids.” u yongbin, director of the centre for potato generation, said. The shed was the first “mog” base for seedlings of potatoes in gansu province。
Wu yongbin stated that when farmers were raising potatoes, they cut up the market's potatoes and planted the roots directly in the ground. “this method of planting has not been treated with any detoxification, and the growth of the roots with the virus can easily lead to the degradation of the potato species, with lower quality and production, and lag behind.” wu yongbin said。
In the field of potato seedlings, the nursery centres have undergone many explorations and innovations, described by u yongbin: “we used the method of cylindrical culture to plant seedlings into cylindrical stones, a powdered substance made up of mineral burning, which has little nutrition of its own and is mostly of a fixed effect on potato seedlings, with high labour costs and more time-consuming.”
However, since the introduction of potato seeding “mog-breeding” technology in breeding centres in 2016, problems such as long breeding cycles, high use of seedlings and low efficiency have been effectively addressed before. The spray technology has truly achieved “earthless cultivation” of potatoes from seedlings to the potato process, which previously required about 120,000 seedlings per acre from the traditional matrix, and now requires only 10,000 and an average of 40 pieces per acre, or 20-30 times the previous one, and modern technology has automated, scaled and standardized potato production。
According to cha xiaoxia, researcher at the center of cultivation, “the fog is also currently a relatively advanced technology in the country, which can escape the temperature limit for the growth of the potato seedlings, with the previous use of neptite only 1 in a year, and the fastest 40 to 50 days from the seedlings to the potatoes, with 2 to 3 in a year”
The area of guangshan, which is deep in the shantytown, is rich in soil, with abundant daylight, high temperature and low infestation, and provides unique natural conditions for potato seeding。
It is one of the poverty-stricken districts identified by gansu province, where the potato industry is a feature of poverty alleviation and income generation. Today, the upgrading of technological and technological tools has contributed to the upgrading of potato commodity production to detoxicate potato production, with farmers growing potatoes at an additional $700 per acre. In accordance with the overall configuration of the county, the potato industry has led to sustained growth in 51 villages, 384 households and a total of 185,000 poor people in the guangshan forest area, accelerating the pace of poverty eradication。
