Team Yuan Longping tried to plant sea rice in Inner Mongolia. What technology is used for sea rice?

The technologies adopted by sea rice include: gene sequencing technology, screening natural salt-tolerant, alkali-tolerant and disease-resistant genes; Conventional breeding, hybridization and molecular marker-assisted breeding techniques.

"Sea rice" is a common name for saline-alkali tolerant rice, which can grow on saline-alkali land such as seaside beach. It does not grow directly in seawater, but is planted on the land where seawater passes. It has three characteristics: it doesn't need fertilization, it is resistant to pests and diseases, and it is resistant to salt and alkali, so it can turn wasteland into fertile land.

Extended data:

Salt-tolerant breeding can save a small part of irrigation cost for planting rice in saline-alkali land. At the same time, the most basic condition for developing rice in saline-alkali land-washing salt with a lot of fresh water can not be ignored. Salt-tolerant breeding is only a supporting measure. It is a long-term ideal goal to develop hundreds of millions of acres of beaches on a large scale to grow rice.

Although "sea rice" cannot grow in seawater for the time being, a large number of beaches and inland saline-alkali land will be the places where "sea rice" will play its role. At present, there are more than 35 million mu of coastal beaches and 65.438+0.5 billion mu of inland saline-alkali land. The salinity of seawater is 3.3%-3.5%. At present, the "sea rice" cultivated in the center is irrigated with 0.3%-0.6% seawater. With the continuous advancement of the research on "sea rice", it is expected that more saline and alkaline water will be used for irrigation.
