惠安县地处福建省东南沿海丘陵池带,常年平均气温20.1——20.2℃,多数年份无霜,个别年份最长霜期也只有39天,年降水量平均1125毫米。大麦在生长期总积温在2000℃左右,雨量300毫米上下,且多集中在大麦生长后期。由于地少人多,土地较贫瘠,长期缺粮。过去,大麦不仅是畜牧业的主要饲料,也是人们生活中的主粮。全县常年大麦种植面积12——13万亩,亩产长期徘徊在200斤上下。由于复种指数高,冬种大麦与前后作季节有一定的矛盾。近年来,随着农业结构的调整,花生种植面积进一步扩大,作为其前作的大麦的发展受到限制,本县啤酒厂每年生产啤酒的原料——大麦芽,均需从浙江等地调入,饲料加工业的原料基本没有大麦。全县科技工作者虽然在大麦品 Huian County is located in the hilly pool in the southeast coast of Fujian Province. The annual average temperature is 20.1 - 20.2 ℃. Most of the years are frost-free. The longest frost period in individual years is only 39 days with an average annual rainfall of 1125 millimeters. The total accumulated temperature of barley in the growing period is about 2000 ℃, the rainfall is about 300 mm, and most of the barley is concentrated in the late stage of barley growth. Due to the small number of people, the land is barren and long-term food shortages. In the past, barley was not only the main feed for animal husbandry but also the staple food in people’s lives. The county perennial barley planting area of ​​12--13 mu, long-term hovering in 200 pounds per mu. As the multiple crop index is high, the winter barley has some contradictions with the season before and after. In recent years, with the adjustment of agricultural structure, peanut acreage has been further expanded, as its predecessor of the development of barley is limited, the county’s annual beer brewery raw material - barley malt, are transferred from Zhejiang and other places, feed Raw materials for processing industry basically no barley. Although the county’s scientific and technological workers in barley products
