Technology of reducing Ice and Snow disaster in Barley

(1) function and use to reduce the degree of harm and promote the growth of wheat seedlings. (2) Technical brief 1. Clear the drainage ditches in the field in time to prevent waterlogging in the wheat field. If the temperature rises slowly and the snow in the wheat field melts slowly after the weather is clear, it may not have a great impact on barley, but after the weather is clear, if the temperature rises quickly, the snow in the wheat field melts quickly, causing stagnant water in the wheat field and causing local waterlogging. It will have an adverse effect on barley turning green and jointing. 2. Topdressing in the field to promote the early growth and rapid development of wheat seedlings. After the snow in the wheat field thawed and the soil thawed, when the barley began to turn green, manpower was quickly organized to topdressing the field, generally applying urea 5kg per mu. Wheat fields with serious freezing injury, poor seedling condition and low soil fertility should be applied more, on the contrary, it should be reduced appropriately. Especially for malting barley, when sowing, the application of base fertilizer is relatively sufficient, and attention should be paid to reduce the amount of topdressing as far as possible, so as not to cause excessive protein content in grains and reduce the quality.
