Four steps of planting Malting Barley

Actively developing the production of beer barley is of great significance to meet the needs of the development of beer industry and speed up the pace of farmers getting rich. In order to realize the high and stable yield of malting barley, four appropriate measures should be achieved: first, the improved variety of malting barley should be properly selected as a special barley for brewing beer. When planting, we should choose high yield, strong disease resistance, strong resistance, thin skin, yellowish color, glossy, disease-free grains. A mildew-free, odorless seed. Two-rowed barley or multi-rowed barley with high germination rate, strong germination potential, uniform grain and moderate protein content should also be selected. Second, the practice of proper sparse sowing has proved that it is unscientific to increase the population structure to get the yield by increasing the sowing rate. Proper sparse sowing can not only save the number of seeds, but also improve the tillering ability. However, it should be noted that the germination rate of seeds must be kept above 90% during sparse sowing. The sowing amount of 8kg per mu is suitable for the plots with early sowing date, more fertilization and high soil fertility, while for the plots with late sowing, low fertility and fertilization level, the sowing amount per mu is about 10kg. Try to achieve intensive cultivation and uniform sowing. The most suitable sowing time for malting barley is around Frosts Descent. Therefore, it should be properly arranged according to the stubble. Third, properly controlling nitrogen and increasing phosphorus in malting barley requires moderate grain protein content and high 1000-grain weight. For Zaoshu 3 barley with yield above 400kg per mu, the total amount of fertilizer applied during the whole growth period was pure nitrogen 20kg. The yield of 250~300kg per mu needs pure nitrogen 10~15kg. Therefore, the application amount of organic fertilizer, phosphorus and potassium fertilizer should be increased and used as base fertilizer. Available nitrogen fertilizer should be used up before the three-leaf stage, spring fertilizer must be applied early, and little or no application should be applied according to seedling conditions. In order to avoid excessive nitrogen fertilizer, resulting in greedy green late maturity and lodging. Fourth, the harvest of malting barley at the right time has strict requirements on the harvest time. When it was found that the stem, leaf and sheath turned green and yellowed, the ear showed light yellow, the grain lost water normally, the hand pressed grain was hard and soft, and the harvest was the best in the wax ripening stage. At this time, the grain harvested contains moderate protein, which can improve the quality of beer. Because beer is made from malting barley and brewed by malting and saccharification, when harvesting malting barley, it should be harvested in sunny days, threshed in time and dried in the sun. Do not dry storage, so as not to heat up in the stack, "steaming" the seed embryo, reduce the germination rate, affect the color and quality.
