In the golden autumn season, the rice fragrant.
In the past few days, in the saline-alkali-tolerant sea rice experimental base in Aregaimai Village, Baiawati Township, Yuepu Lake County, Kashgar, 300 acres of golden rice fields are lined up neatly. The machine was busy harvesting sea rice in the rice field.
This year, the per mu yield of sea rice reached 575.3 kg, an increase of 27.3 kg over 2020.
Sea rice is also called saline-alkali-tolerant rice, which is a kind of rice variety that can grow in a certain concentration of saline-alkali soil.
Yuepu Lake County, where the sea rice experimental base is located, has serious soil salinization, with a pH of 7.8. 90% of the cultivated land contains more than 15% of the soil salt content, which is regarded as an "agricultural desert."
Since 2018, the Qingdao Sea Rice R&D Center of Academician Yuan Longping has used Are Gaimai Village as one of the first batch of saline-alkali rice cultivation experiment bases in the country to conduct sea rice planting experiments.
During the planting period, the experimental base combined a variety of irrigation methods, and constantly replaced and improved the varieties of sea rice planted. After rice cultivation was improved, the salinity of the experimental field dropped from the original 17 per thousand to the current 2 per thousand. The fertile land standard.
After the sea rice is harvested, winter wheat will be re-sown, and the researchers will further observe and test the growth of winter wheat.
