On the golden autumn festival, a thousand acres of potato fields in the village of liang in guangzhou county, green-oiled potatoes were running along the membranes, agricultural technicians pulled out the soil, a full-fledged potato came out, and receiving experts and growers could not help but nod. This is the site of a project of the provincial agricultural institute's priority research and development programme on science, technology and innovation, entitled “model study of key production techniques for potato along the western corridor of the river”. On-site, the average acre production of potatoes was 5632. 03 kg, based on an integrated “two-way” hydrofertilization technique developed by the scientific team。
"the potatoes used to be grown with experience." zhang chengbin, head of the haihong agricultural and livestock professional co-operative in guolong county, said that “the species are old, their yields are low and their chips are malformed; water is more difficult to water, and the water is sour that it not only costs water, but also brings up the salt in the ground, which is up to 2,000 kilograms per acre”
The plight of zhang sung bin is a microcosm of potato cultivation along the sandy zone along the western corridor. This land, irrigated by the melting of glaciers in the mountains, which has the advantage of abundant light and heat and of high soil potassium, makes “good resources” “effective” because of, inter alia, drought, degradation of varieties, salinization of soils and shortage of labour. In 2023, the potato institute of the provincial agricultural institute solved the problem of planting。
“we first introduced 15 potato varieties from seeds, and tested them in the districts of minqin, guangpo and xinta 3, resulting in the screening of two to three varieties suitable for the sand strip.” the project manager, vice-researcher of the institute of potato at the provincial agricultural institute, hwang wei, described the fact that the western corridor along the sand strip contained soil sterilisation, deep-dwelling soil, high organic content and high potassium content, and that the region produced a dry potato content of 19. 1 to 26. 7 per cent, starch content of 15. 97 to 21. 25 per cent and protein content of 1. 18 to 2. 44 per cent, with high quality indicators。
How can we produce more if we have chosen the varieties? The scientific team has developed an integrated technology for water fertilization that is dripping under the “twilight strip” membrane. In the demonstration field, two rows of potatoes were planted on a tall top, a drip belt was laid in the middle, covered with a white membrane and a thin layer of soil. Yellow wei pointed to the membrane interpretation: “the membrane increases soil temperature, allows potatoes to be marketed early, the membranes are windproof, the membrane drip is accurate in refilling water, and water fertilization efficiency is increased by 15 to 25 per cent.”
What is more important to growers is mechanization of the whole process. The joint harvester travels through the fields, and the chips are finely separated, packed, and no more artificially bending to scratch. “the 2,000 acres that used to be planted were about 50 people a month in light, and now five machines can be completed in a week. A single machine can complete the four processes of seeding, dripping belts, covering membranes and covering the earth, saving more than half of the cost, making an extra $1,500 this year in an acre.” zhang sung bin has made a debt。
Pest control was once the “heart disease” of growers. The project team established an integrated control system for “agriculture+bio-physico+chemical”, which selects disease resistant varieties, uses stickers, insecticidal lamps, biopesticide precision control, and can view field pests and pests on mobile phones through smart surveillance systems。
“this technology has expanded the potato-producing areas in gansu province and has led to innovative models of agricultural development along the sand strip, increasing the economic income of farmers.” the director of the provincial agricultural technology promotion station, li se-sheng, has improved the utilization of land resources and reduced production costs, as well as the production of potatoes, through agro-machine farming integration. At present, 2,000 acres of potato fields have become “model fields” and 20,000 acres of high-quality potatoes have been planted in the kulong district and tianjo district, among others.
