利用冬春气候条件发展长江中游大麦生产

大麦是世界四大谷类作物之一，以适应性强、抗塑性强、抗逆性好、用途广而在世界各大洲广为种植。二次世界大战后，随着经济发展，大麦产量由６０年代的９９７０．０万ｔ增加到１９９４年的１５８７２．８万Ｔ，长江 中游历来是我国大麦的主要种植之一，随着我国经济的发展，大麦生产经况愈下，成为我国进口量最大的农产品之一，其种植面积由１９６１年７７．９２７万ｈｍ＾２降为１９９５年的８．３４８万ｈｍ＾２，与世界经济越发

DEVELOPING BARLEY PRODUCTION BY USING WINTER SPRING NATURAL RESOURCES OF THE MIDDLE CHANGJIANG RIVER BASIN

Barley,being widely planted in the world due to its strong adaptability,adverseity resistance and wide utility,is one of the four major cereal crops in the world.With economic development after the second world war,the globle barley production increased from 99.7 milion ton in the 1960's to 158.728 million ton in 1994. The Middle Changjiang River Basin was one of the main barley planting areas in China.With the fast growth of our economy,however,the output of barley decreased rigorously this area and barly became one of the major agricultural imports.The area for planting barley reduced from 779 720 hectares in 1961 to 83 480 hectares in 1995.This was quite different from the trend of world barley production. The Middle Changjiang River Basin has good conditions for barley production.Besides,the potential market of barley is great.Developing barley production by using winter spring natural resources has strategic significance in restructuring our planting model,promoting the combination of agriculture and animal husbandry,increasing farmer's income and changing the situation that feed has to be transported from the North to the South.Suggestions and srategies for solving the main problems of barley production in the Middle Changiang River Basin are made.
