Echinochloa frumentacea Link is a better annual grass. Tolerant to salt and alkali, waterlogging—resistance and with high economic effects. It can endure 0.5％ concn, of soil total salt, 37％ conch, of soil alkalinity, and can grown in the soil condition of pH 8.3-9.5. The seedlings grow normally in soil maximum moisture Gapacity of 100％, and didn’t lodge, even can fruit, ripen, under the condition of soil moisture over saturated in the Periods of shooting, filling and fruiting.
In the salinized, alkalized and relrogiessive grass land, yieds about 5000kg/ha, of the grass may be obtained that is about 7 times compared with the output of original grass in the grass land. The concentration of absorbing salt and alkali are higher than millet and broom corn millet, especially of absorbing Na, 100g dry matter of plant can absorb Na (expressed with sodium oxide) 6.7 times as strong as millet and 3.1 time as broom corn millet. It’s a higher efficient grass for improvement of salinized and alkalized grass land, and inoreasing productivity.
