摘要: 对早春作物光温资源优势进行了综合分析,测定了五种早春作物的叶面积指数、干物质积累与净同化率、茎叶中蛋白质、可溶性糖含量等生理指标和产量、产值。不同作物比较试验表明,攀西地区早春作物以种植玉米、西瓜、马铃薯的产量和产值较高。

关键词: 早春作物, 光温资源, 生理效应, 产量

Abstract: The early spring crop's advantages of light or temperature resources were analyced, and five early spring crop's physiological targets or yield and output value were measured. These physiological targets include leaf area index, dry matter accumulated and net assimilataion rate, protein and soluble carbohydrate content in the early spring crops. The comparative experiments of different crops show that it is better to plant maize, watermelon and potato in Pan-Xi region, because of the higher yield and output value.

Key words: EARLY SPRING CROPS, LIGHT OR TEMPERATRATURE RESOURCES, PHYSIOLOGICAL EFFECTS, YIELD
