After 20 years' research, research staffs from the Jilin Provincial Institute of Biology Science solved the problem of salina, and realized the mass planting of Jisheng Chinese Wildrye.

Due to environmental deterioration, the grassland in the middle and west of Jilin Province turned sterile salina. Though some places still had grass, its grass output was very low. In 1979, Hao Shui, an academician from the Northeast Normal University and research staffs from the Jilin Provincial Institute of Biology Science began to study the problem. They worked on the desert for a long time, made in-depth and systematical researches. Based on the researches, they employed the new technology of plant transmigration choosing breeding, and produced the first generation high-yield, high-quality, drought-resistant and saline-alkali resistant new varieties by artificial breeding in the world -- Jisheng No.1, 2, 3, 4. Due to excellent resistance and high yield, they were acclaimed as Supergrass in the world.

With the planting of Jisheng Chinese Wildrye on salina, the desert again became oasis. The hay yield per hectare is 7.50 tons, the seed yield per hectare is 150 kilograms, the emergence rate is over 50% higher than wild Chinese Wildrye. The content of coarse protein is 6~9.45%, which is 10~70% higher compared with wild Chinese Wildrye. The effect of stimulating the secretion of milk is raised by 13%, compared with the wild Chinese Wildrye, the coverage degree can reach 100% in three years on medium-heavy degree saline-alkali soil, they are suitable for cultivation in dry areas in western China where annual rainfall is 300mm on the average. It can be used for transforming middle-low yield land, improving natural grassland, conserving water and soil, windbreaking and sand fixing and flood-controlling-dam protecting. It is delicious food for horses, cattle and sheep, and can be used for herding, modulating hay.
