1959和1962年棉花高产施肥技术研究结果,肯定了南京地区亩产皮棉150斤左右的施肥原则,应该是在中等地力的基础上,适当施基肥、苗花期追肥二次。苗期施肥要早、轻、速效(化肥或粪尿),水肥结合集中施用,促进早苗、壮苗。花肥宜在梅尾伏旱初施用,有机肥与化肥配合重施。如能在定苗后和盛花结铃期看苗补肥,更可获得苗长势一
The results of high yield fertilization techniques in 1959 and 1962 confirmed the fertilization principle of about 150 kg per mu in lint area in Nanjing. Fertilization should be done on the basis of moderate soil fertility and secondary fertilization at seedling flowering stage. Seedling fertilizer to early, light, quick (fertilizer or excreta), water and fertilizer combined with the focus on the promotion of seedlings, strong seedlings. Flower fertilizer should be used in the beginning of Mei Mei drought, organic fertilizer and fertilizer re-Shi. If Dingmiao and flowering climax to see Miao Bufei, but also to get a Miao growth
