摘要
本文在对全省玉米生产区光温资源及生产情况全面调查的基础上,根据范·费尔图依森介绍的Dewit公式,对玉米生产潜力进行了分析。结果表明:我省玉米生产光温潜力很大.春玉米一般均在880公斤/亩以上,最高产量可达1228.28公斤/亩。夏玉米也在550公斤/亩以上,依此,作者提出了挖掘我省玉米生产潜力的综合措施。同时,也为玉米育种工作者培育适应不同区域玉米品种提供了依据。
Based on the investigation of light—temperature resource and production conditions of maize on the whole province, the production potentiality of maize was analyzed in the paper. According to Dewit formula introduced by Fan. Filltonjson, the calculated results show: production potentiality of maize in shanxi is great, spring sowing maize is above 880kg/mu and summer sowing maize is above 530kg/mu, the maximum yield can reach 1228. 28kg/mu. combined with local conditions, it was suggested that multiple agronomic measurements of increasing maize yield. The results also provided a basis for workers of maize breeding field.
