Technical Measures to Reduce Barley Losses from Snow and Ice Disasters
At present, the growth of barley in the field has entered a critical stage. To ensure high and stable barley yields, it is especially important to strengthen field management during the middle and late stages. Generally, the following cultivation and management measures should be adopted. Scientific and economical water use. Choose to irrigate barley once each from booting to heading and from grain filling to the milk-ripe stage. The heading and grain-filling periods are a...

1. Promptly clear and dredge field drainage ditches to prevent waterlogging in the wheat field. If the temperature rises slowly after the weather clears and the snow in the wheat field melts gradually, it may not cause a major impact on barley. However, after the weather clears, if the temperature rises quickly, causing the snow in the wheat field to melt rapidly, this will create standing water in the wheat field and cause localized waterlogging, which will adversely affect barley's green-up and jointing.
2. Apply topdressing in the field to promote early and rapid growth of wheat seedlings. After the snow in the wheat field melts and the soil thaws, when barley begins to turn green, quickly organize labor for field topdressing, generally applying 5 kg of urea per mu. Wheat fields with severe freeze damage, poor seedling conditions, and lower soil fertility should receive more fertilizer; otherwise, it should be appropriately reduced. In particular, for malting barley, the base fertilizer applied at sowing is relatively sufficient, so care should be taken to minimize the amount of topdressing as much as possible to avoid causing excessively high protein content in the grains and reducing quality.
