摘要
本文运用经改进的Kassam-Wageningen法,对江苏省4大粮食作物的光、温、水生产潜力与土壤的影响进行了逐级计算,对全省6个农区粮食生产力的地理分布,未来40年的发展,及其满足人口需求的能力做出分析与预测,提出了今后实现粮食生产与人口消耗良性平衡的策略。
In terms of the improved Kassam-W ageningen method, calcu-lation is made level by level of the effects of light, temperature, waterproductive potentiality and soil upon the four major grain crops in theprovince. The geographic distribution of the crop productivity in sixfarming areas is given together with the prediction of the developmentof the productivity for the forty years ahead. Analysis is made of theproductive potentiality to meet the needs of the population growth,followed by the presentation of useful measures for the balance between the necessity and production of crops.
