The sea rice that was first planted in the five typical saline-alkaline soils this year has grown well and is about to be harvested. Sea rice is a high-yielding rice with saline-alkaline resistance. It can grow on mudflats and saline-alkaline soil. China's arable land resources are limited, experts estimate that if the sea rice planting area reaches 100 million mu, the total yield could reach at least 30 billion kilograms, which could feed 80 million people in China.
