The coastal salt-resistant rice cultivation was breached: south salt 1 acre produced over 561 kg
On 22 october, the survey site for salt-resistant rice varieties, “salpha 1” and “salpha 21”, was held at jiangsu suntai farm in jiangsu salt city. On-site results were measured at the harvest, disemboweling, hydrometric and weighing levels, resulting in 561. 1 kg and 531. 5 kg of acre production, respectively。

Jiangsu suntai farm is a demonstration base for saline-resistant rice resource screening, breeding and new varieties in the centre of the national centre for salin resilient rice technology innovation. The two species surveyed were new varieties of high-quality, salt-resistant rice with an area of more than 40 acres, suitable for freshwater irrigation in saline soils of less than 0. 5 per cent of the soil along the yellow rice plague in jiangsu and shandong provinces。

Of these, “salpha 1” was selected by the academy of agricultural sciences of jiangsu province, approved by the state in 2021, included by the ministry of agriculture and rural affairs in 2022 in the main food oil production varieties, was authorized to plant new varieties in 2023, seeded on 15 may this year, planted on 8 june, smoked on 25 august, and “salpha 21” was selected by the institute of agricultural sciences of jiangsu zone, approved by the state in 2021, applied for new plant varieties rights in 2022, with the same seeding and planting time as the former, and pecked on 28 august。

It was described as a rapid and efficient de-salinization of the soil of the salinous coastal areas through “ploughing, bubbles, dredges, twirling, flat” 5n, with rapid and efficient de-salinization through multi-cycle cycles and multiple water-spring cultivation, the core and key technical importance of which is repeated water-silviculture, accompanied by the implementation of technological systems such as “deep pine, irrigated, multi-swirling, good seed, deep-planted and fat”. Rice cultivation was followed by technological innovations that led to rapid, productive and improved use of economic, simple and efficient saltlands。

In september and october this year, new breakthroughs were made in the cultivation of salin rice in the north-east centre and the north-west centre of the national centre for salphaline technology innovation, with the choice of the north-east centre to produce 508. 6 kg of a demonstration acres of the salt-resistant rice species of “dry rice 21”; the north-west centre chose to produce a 10,000-acre chain of the first division of the new rice 36 to produce in xinjiang city, with an average of 573. 8 kg measured by experts。

The director of the national centre for salphatic rice technology and innovation in china's engineering institute, pao lianyang, said that the results of several centres showed that the centres had achieved good results in the fields of salaline rice breeding, salin land improvement, etc., and demonstrated the enormous potential of salin lands, giving us greater confidence in the spread of salaline rice。

According to paronyang, it is very strategic, according to preliminary estimates, to estimate that about 100 million acres of our country have salinized land with the potential to grow rice, and if, in the future, all salinized rice is planted on those salinized land, our annual rice production in salinized land is equivalent to one year of food production in provinces such as hunan. The center for the future will be working on the development of better varieties and improved techniques for saline land improvement, and will put in place a genuine “gear-to-earth” approach to helping saline rice to contribute more to national food security。
The series of activities, such as the survey, was organized by the national centre for salin responsive rice technology innovation, and hosted by the national centre for salin resisting rice technology innovation, the faculty of agricultural sciences of jiangsu province, the academy of agricultural sciences of salt cities, etc。
