Yuan Longping’s team set a new record for high rice yield in saline-alkali land. How high has it been?

On the afternoon of October 14th, the salt-tolerant rice grown by Yuan Longping's "sea rice" team and the Jiangsu Provincial Agricultural Technology Extension Station were tested for yield in the Tuocha Fang Ling Reclamation Area in Rudong, Jiangsu. According to calculations, " The average yield per mu of "Chaoyou Qianhao" salt-tolerant rice reached 802.9 kilograms, setting a new record for high yield of rice in saline-alkali land.

At the production test site, the expert team conducted actual mechanical harvesting tests on three rice fields of about 1 mu each. The variety tested this time was the "Super Quality Thousand" salt-tolerant rice developed by Yuan Longping's team. The expert team Through harvesting, moisture measurement, area measurement, and weighing, the yield per mu was finally calculated to be over 800 kilograms, marking the success of high-yield rice research in the eastern coastal saline-alkali land in Rudong, Jiangsu.

"Seawater rice" grown with new technology

"Seawater rice" refers to rice varieties that can grow in saline-alkali soil with a certain concentration. In recent years, Yuan Longping's "sea rice" team has been committed to cultivating "sea rice" with high yield and high salt tolerance to ensure my country's food security. This year, Yuan Longping's "sea rice" team established "sea rice" experimental demonstration planting bases in five major categories of saline-alkali areas across the country. For example, the Chafang Lingken District in Dongtuan, which is a saline-alkali land type on the eastern coast, is the only experimental demonstration planting base selected in our province.

The Fangling Reclamation Area where the "Sea Rice" experimental base is located was formed by reclamation in 2010. It is a coastal sandy saline soil with a soil salt content between 2 and 6 parts per thousand.

In May this year, after the four varieties were transplanted, Rudong used the "Key Technologies and Innovative Applications of Precise Quantitative Cultivation in Main Rice Producing Areas" and "Key Technologies for Mechanical Transplanting Cultivation of Rice in Multi-ripening Areas" that were originally promoted and applied High-yielding cultivation technologies such as "Innovation and Application" and "Integrated Technology of Machine-Planted Rice with Lateral Deep Fertilization" are combined with the physical and chemical characteristics of the soil in saline-alkali soil. According to the unusual plum rain weather and high incidence of diseases and insect pests, we can flexibly adjust and apply the cultivation technology for strong seedlings and early emergence of rice in saline-alkali soil. The ultra-high-yield fertilizer and water efficient operation technology and the green prevention and control technology of pests, diseases and weeds effectively ensured that the demonstration planting achieved the expected success.
