Radiation 401 barley is a new breed introduced from the United States. From 1984 to 1986, the trial breeding was carried out. From 1986 to 1988, the demonstration and popularization area was more than 4,000 mu, and the general mu production was more than 350 kg. The yield was 50 to 75 kilograms more than that of the two-rowed barley such as Supi No.1 and Zhoumai 1; Up to 518.4 kg. Now high-yielding cultivation techniques, introduced below. First, the main production traits 401 semi-winter varieties of radiation, sown in mid-October, emergence to maturity 218 days, about 85 cm tall, 15 to 16 leaves of the main stem, the ground above the 5 to 6 internodes.
