Sichuan has been affected by cold air and has seen rain and snow in recent days. On 24 january, in the town of caucasian, hokkai city, in a shed of more than 3,000 square metres of super-heat room, the cold was not felt and the potatoes were immersed, dug, laid, covered, covered... A dozen villagers are systematically preparing for seedlings of sweet potatoes. At the same time, a major agricultural synergistic extension project in 2023 — the application of technology for the production of seedlings in the canyon canopy — will be held here。
It is known that the seedlings were more conventional, more than a month earlier. According to zhang deung, vice-president and senior agronomist of the ebei city academy of agricultural sciences, local seedlings generally begin to grow after march, when temperatures begin to rise。
Why is it more than a month early? Journalists entered the greenhouse shed and suddenly felt a heat bump。
“the temperature in the shed is a few degrees higher than outside, with only 1-2°c outside and about 10°c in the shed.” in addition to the arch shed outside, zhang deok-kyung described each cassava bed as being covered with bamboo and a thin film. “the cultivation of potatoes is cold, and the double arches can overcome the cold effects of winter and ensure that the seeding of potatoes is rapidly growing and growing at the most suitable temperatures.”
“for the time being, seedlings of red potatoes are dominated by open seedlings, membrane-covered seedlings, small arch sheds and seedlings, the temperature of which cannot be guaranteed.” du yongli, assistant researcher at the faculty of agricultural sciences of the city of ebein, presented the development of the double archer technology, which became our provincial agricultural leader and became the local standard for the city in 2023, after many years of research。
The cold has just passed, entering the coldest hour of the year. According to du yongli, “temperature is the most critical factor affecting the seedlings of red potatoes. They can be bred at the coldest times, using double arch nursery techniques.”
Early seedlings mean early planting and morning marketing, thus avoiding the peak of the market for sweet potatoes and obtaining better market prices. Hu chi li, head of the peaksand potato industries ltd., said that “it was the peak of the market around october, selling only about 5 cents per pound, and up to august and september, the price could reach about 1. 5 dollars”
“in addition to this, there is the advantage of early childbearing, which can increase the acre production by more than 1,000 pounds due to longer birth cycles and higher production of sweet potatoes.” sichuan academy of agricultural sciences, sichuan academy of agricultural sciences, and sichuan tsato innovation team development team, expert in shen seng。
It is known that the seeding of potatoes is 221, which is used for high starch processing. In recent years, the maidan village has introduced pegasus cosmetic industries ltd. In the city of ibein to develop potato cultivation and deep processing industries in the form of “village collective economic holdings + business operations + technical guidance from agricultural colleges”. "the most important nutrient starch in the sweet potatoes can be used to make dust bars, and we are trying to extract less protein and cellulose from them, and once successful, the economic value is higher than that of starch."。
To date, the village has developed more than 4,000 acres of sweet potatoes, which have become the backbone of the revival of the village of the peace village, and zhang deyun, secretary of the security village branch, has told journalists that “two to three acres of land per village, one acre of sole production of sweet potatoes, amounting to 4 to 5 tons, can grow another season of oil with a steady income of 2000 to 3,000 dollars per acre due to guaranteed sales”
