At the moment, a large part of the city's saline fields is giving rise to new hopes for the rebirth of the base. Over the past two years, zhang jiaguchi has fully exploited the potential of salin lands, actively explored new models for the integrated use of salin lands, upgraded through zonal classification, diversified variety selection and greater local branding, and continuously increased salin land improvement, increased salin land management and increased salin land output efficiency. Since last year, the new city-wide upgrading of 3. 26 million acres of saline arable land has given new impetus to the further development of quality agriculture。
The city as a whole has implemented saline upgrading in five priority districts of zhangbei, kungbao, maung yi and huai, based on the principles of zonal classification and food-for-food, food-for-food, grass-weed and grass-weed. Among these, kanbo county has actively explored the “deep tillage + bio-organic fertilisation + corrosive acid/organ silicate compound fertilizer” model, with measures such as mechanical tillage and application of soil improvement agents, organic fertilizers, reducing soil salinization from 1. 36 g/kg to 1. 23 g/kg, with ph values in the range of 7-7. 5, with an increase of 19. 67 per cent, 24. 99 per cent and 15. 56 per cent, respectively, in the average single production of saline, aluminum and aluminum. In huai county, integrated management measures such as irrigation desalination, soil dysentery and increased organic fertilizer were implemented, with the average organic content rising from 12. 0 g/kg before modification to 15. 2 g/kg and soil salinity from 0. 465 mg/l to 0. 445 mg/l。
The city-wide combination of “locally appropriate species” and “cropping land” has diversified the variety selection and targeting to increase crop yields. Salt coercion tests, field and indoor identification of eight crops such as grains, oats and quinoa were carried out to screen a batch of salin-resistant materials from 1125 resources; at the same time, 27 new varieties were introduced and selected, 4 new varieties were refined and 2 new products were converted; crops such as salin-resistant maize varieties were also produced “single 998” and showed good endurance, salin-resistant and integrated resistance; in addition, the project “salin-resistant-specific crop varieties selection and demonstration” was implemented in 22,325 acres in 6 districts, such as chongbao, shanyi, were tested for cultivation for three consecutive years, with an increase of 8. 3 to 16. 0 per cent over crops such as magma, salvo, salfa, and sorghumin, with an increase of 41. 9 per cent。
To further explore the potential for salinization, the city-wide mapping of unique local salin land varieties such as quinoa, oats, and gonmi, and salted ground elements such as “gymmal” and “salin” and “ami” have continued to expand the competitive advantage of “no man, no man, no man, no man”, and the associated regional public brands, through the promotion of brand-building programmes, outreach to focus on displays, participation in large-scale marketing matches, and innovation in the “salin +salin brand” agricultural literature brigade. At present, the city has further expanded its distribution channels with salinized products of oats, quinoa, grains, linen and barley and their processed products, steadily moving to the national level, with cumulative sales of $181 million over the past year。
The former saline fields in the four camps in the village of white land kilns have now become a pilot base for new varieties of quinoa and a base for large-scale organic cultivation. Han jie, han peng fei
