| 摘 要： | 本文采用H.T.Van Velthizen生产潜势估算方法,结合吉林省中部地区自然资源实际,并对有关参数加以修正后,就主要农作物的潜在生产力进行了连续8年的估算。结果表明,本地区各作物的现实生产力与潜在生产力间均有较大差距。为充分发挥本地区作物生产潜力,必须提高地力,实行节水耕作,扩大灌溉面积。

| Abstract: | The potential productivities of crops of dryland in central plain of Jilin province have been estimated for eight years. The method described by H. T. Van Velthizen was used in estimation with corrections of some parameters. The result showed that there was a great disparity between the two productivities. In order to bring the potential productivity into full play, the fertility and water conservancy facilities should be improv-ed and the irrigated area should be expand. |
