本文根据1977—1981年田间试验结果提出了大豆亩产450斤的10项生理参数并简要涉及了几项基本栽培措施。讨论了亩产450斤的大豆群体的叶面积指数动态和最大叶面积指数,平均净光合率、总光合势,生物产量、器官平衡和经济系数、生物产量的日增长量和最大增长量、CO_2同化量、需水量、土壤NPK带出量、光能利用率。大豆亩产450斤是目前黑、吉、辽大豆主产区可以普及的高产指标。要实现这一指标,必须注意种植密度,建立合理的群体结构,施用有机肥、过磷酸钙,还要适量地施用氮肥,在干旱时则要灌水。
Based on the field test from 1977 to 1981, this paper proposed 10 physiological parameters of 450 kg of soybean per mu and briefly introduced several basic cultivation measures. The leaf area index dynamic, the maximum leaf area index, the average net photosynthetic rate, the total photosynthetic potential, the biomass, the organ balance and the economic coefficient, the daily growth and the maximum growth of the biological yield of 450 kg per mu of soybean population were discussed. Assimilation amount, water demand, soil NPK outtake, light energy utilization rate 450 kg soybean yield is the current black, Kyrgyzstan, Liaoning soybean production areas can be popular high yield indicators. To achieve this target, we must pay attention to planting density, establish a reasonable population structure, the application of organic fertilizer, superphosphate, but also the appropriate amount of nitrogen fertilizer, irrigation in the drought will.
