摘要
对小麦-玉米周年高产地区的土壤质地、土壤养分含量以及生长季内光、温、水等因素进行了分析。结果表明,各高产地区的生态条件在正常年份基本上都能满足作物的高产需要,但地区间光热资源在两个生长季的配置不尽相同;小麦、玉米进一步高产,应因地制宜进行高产技术突破,充分挖掘光热资源的增产潜力。
The soil texture,soil nutrient content and some factors,including light,temperature and water in growth period,were analyzed in the areas with annual high-yielding wheat and maize.The results showed that the ecological conditions of high-yielding areas could meet high-yielding need in normal years,but the distribution of photo-thermal resources was different between two growth periods.So different cultivation approaches should be adopted to improve the natural resources efficiently for higher yield according to local ecological conditions.
