应用核示踪的方法,研究了高产小麦有机肥与无机肥配施对光合产物的积累、运转与分配以及对磷的吸收利用的影响,结果表明:配施比单施及对照的光合强度均有所增加,尤其苗期,呼吸强度的变化也有相同的趋势。拔节后配施处理分往穗部的光合产物明显低于单施及对照。根系对磷的吸收利用,冬前与返青期配施处理优于单施与对照,返青后则相反。 The effect of organic manure and inorganic fertilizers on the accumulation, transportation and distribution of photosynthetic products and phosphorus uptake and utilization of high yield wheat was studied by using nuclear tracing method. The results showed that the photosynthetic intensity Increased, especially in seedling stage, the same trend of changes in respiratory intensity. After jointing, the photosynthetic products of spikelets were significantly lower than those of single and control. Root phosphorus absorption and utilization, pre-winter and return greening treatment is better than the single application and control, turning green after the contrary.
