An ancient saying goes: "High mountains, long rivers, favorable terrain, and harmonious people."
This phrase profoundly reflects the Chinese people's deep understanding and flexible application of the land, demonstrating their adaptive survival wisdom.
However, along coastal areas lies a forgotten land—alkaline soil.
These lands, due to prolonged exposure to seawater, have extremely high soil salinity, making it difficult for most plants to survive, let alone become productive farmland.
Historically, alkaline soil has been considered barren, accompanied by endless suffering and poverty.
However, in recent years, a miraculous crop named "sea rice" has emerged.
This unique rice variety is not only tall and robust, resistant to drought and wind, but can also grow on beaches and alkaline soil, bringing new hope to these lands.
The promotion of sea rice cultivation has not only improved the soil structure of alkaline land but also saved on pesticide expenses.
More importantly, sea rice not only adapts to alkaline soil but also transforms it.
After years of sea rice cultivation, the soil structure of alkaline land has significantly improved, and now it can support the growth of regular rice and peanuts.
In 2017, sea rice officially began large-scale cultivation.
With support from national policies, the cultivation area of sea rice has exceeded 1 million acres and is gradually being promoted in multiple provinces nationwide.
Sea rice has not only transformed barren alkaline land into fertile farmland but also provided a feasible solution to the food and clothing problem for hundreds of millions of people.
Against the backdrop of global food crises and increasingly scarce land resources, China's development of "sea rice" capable of growing in alkaline soil is not only an agricultural technological leap but also opens up new prospects for global food production.
However, truly understanding the value of sea rice requires delving into its significant roles in food security, ecological environment, and economic development.
Firstly, the emergence of sea rice is of great significance in addressing China's food security issues.
Statistics show that China has about 1.5 billion mu of unused alkaline land, of which approximately 550 million mu are suitable for sea rice cultivation.
If these alkaline lands can be fully utilized, with a yield of 800 kilograms per mu, an annual harvest of over 400 billion kilograms can be obtained, enough to feed 200 million people, providing a solid foundation for China's food security.
Secondly, sea rice cultivation is of great significance in improving the ecological environment.
High salinity in coastal lands is unfavorable for pests' survival. Sea rice cultivation can save on pesticide use, and the tidal ebb and flow of seawater bring abundant trace elements and natural organic fertilizers, reducing the cost of agricultural production.
Additionally, sea rice can change the soil structure of alkaline land, improve soil fertility, and promote the ecological restoration and protection of alkaline land.
Thirdly, the widespread cultivation of sea rice plays a positive role in promoting economic development.
Sea rice cultivation can increase farmers' income, improve rural economic structure, and promote rural employment.
At the same time, sea rice cultivation can also drive the development of related industrial chains, such as seed production, agricultural machinery manufacturing, agricultural technology services, etc., providing new impetus for the transformation and upgrading of rural economy.
In summary, the emergence of sea rice not only provides a new option for China's food security but also brings new opportunities for ecological environment protection and economic development.
