光合—微肥是山东省科学院生物所研制的,是一种叶面肥,主要含有农作物生长、发育所必须的硼、锰、铁,铜,钼等微量元素和光呼吸抑制剂,因此具有光合肥和微肥的双重增产效果。我所于1992年秋冬在大白菜、大葱上做了喷施试验,试验结果表明,该肥具有良好的增产效果。大白菜上平均每亩增产2476.8公斤,增产率为19.4％;大葱上平均每亩增产671.8公斤,不仅提高了大白菜净菜率,而叶球紧实度也有 Photosynthesis - fertilizer is the Shandong Institute of Biology developed by the Institute, is a foliar fertilizer, mainly containing crops for growth and development of the necessary boron, manganese, iron, copper, molybdenum and other trace elements and photorespiratory inhibitors, so with photosynthetic fertilizer And double fertilizers increase yield. I was in the fall and winter of 1992 in cabbage, green onions spray test done, the test results show that the fertilizer has a good yield. The average yield of Chinese cabbage per hectare increased 2476.8 kilograms, an increase of 19.4% yield; onions on the average yield of 671.8 kilograms per mu, not only increased the rate of Chinese cabbage netting, and leaf compactness also
