He xiaoxia's at the potato misty pie base to check on the potato
Potato is the fourth largest food crop in the country, with 360,000 acres of potato cultivation in gansu county. Here, a “long run” around the potato industry has been going on for decades. As a county breeding unit, the agricultural technology extension centre of the quantuan county, with the support of a generation of scientists, has independently produced over 10 new varieties of potatoes, using ten years of strength to sharpen the sword, and has written a vivid sample of “the county unit can also breed”。
At the moment, this is the critical period of potato cultivation. At the potato breeding base in yongning town, the agronomist yoo xiaolong and his colleagues are experimenting with fields to guide potato cultivation, with precise records of the location and variety of each potato plant. Each of these data provides a scientific basis for the selection of varieties, from the onset of seedlings, to the flowering period, to the potato season and to the later stage of the infection, to post-harvest scabies, etc。
“a seed and a potato bear our expectations, and every record and every screening is paving the way for the cultivation of good varieties.” liu xiaolong said。
Potato breeding is a long journey, and the birth of each new species takes at least 10 years. According to the staff of the agricultural technology promotion centre of sampong county, who are engaged in potato breeding, a senior farmer, su xiaolong, the seeding begins with selective and excellent hand-in-hand material, through a combination of pollination, followed by non-sexual reproduction, which requires repeated selection, phase-out, referral to provincial or national-level regional trials of high performers, and eventual registration of varieties through disease identification, quality analysis, etc。

It has been this year after year that the fruits of breeding in the quantuan district have emerged. “following the validation of the national varieties of potato 3 in 2011 and the award of the first prize for scientific and technological progress in gansu province in 2012 for the selection and demonstration of new potato 3 varieties, we have successfully selected several new varieties of potato 4, 5, 6, 7 and 8. These varieties consist mainly of medium- and late-literate high starch types, taking into account the medium- and early-literate types, and form a structured variety ladder.” mahosuk, deputy director of the agricultural technology promotion centre of quantuan county, said。
The fruits of breeding need to be translated into field productivity and efficient seeding of potatoes. Entering the misty greenhouse at the potato detoxification centre in squirty county, a line of potato roots are hanging in a closed planting box, without soil or mud, and the fine trophic fluid is sprayed in the fog and immersed in all of them. A potato washes a “nutrient bath”。
“an average of 40 to 50 microfassiles, 20 to 30 times the size of traditional matrix cultivation, significantly increasing the efficiency of microfascal production.” the director of the potato detoxification centre of the state of sampshi county, who looked at the growth of the potato industry, said that the centre, through advanced techniques such as strangulation, breeching, mist microfascing and sourning, had expanded its disease-resistant and high-yielding varieties of fine potatoes and had produced 852,000 potatoes this year, of which 128,000 were water-fed, 460,000 were gestationed and 226 were implanted。
The tsang county, which is bound by the two main lines of autonomous breeding and scientific innovation, innovates breeding techniques, builds a solid seed base, breaks down planting bottlenecks with the strength of the county level, grinds a “potato” for 10 years and makes “small potatoes” a “big engine” for rural renewal, writing a vivid survey of the county's agricultural innovation。
