我场位于黄海中部沿海平原，属江苏省沿海旱作大麦区，常年秋末冬初气温下降缓慢，日照较充足，对大麦播种、出苗、提高幼苗的抗寒能力有利。但春季气温回升慢而不稳，常有北方寒流入侵，倒春寒对啤酒大麦生产常有威胁。冻害是常见的自然灾害之一。在啤麦生育过程中，几乎每年 My field is located in the central Yellow Sea coastal plain, Jiangsu Province is a coastal dry barley area, perennial late autumn and winter temperature dropped slowly, sunshine more adequate for barley sowing, seedling, improve cold tolerance of seedlings is beneficial. However, the spring temperature slowed down and instability, often cold intrusion in the North, late spring cold beer barley production often threatened. Frost damage is one of the common natural disasters. In the process of beer malting, almost every year
