Problems solved by technology

The formula of the honey pomelo special fertilizer is reasonable, which solves a series of fertilization problems such as difficulty in fertilizer selection, large amount of fertilizer application, and unreasonable fertilization location in Pinghe County, Fujian Province. It can meet the nutrient requirements and nutritional functions of honey pomelo at different growth stages, and improve Yield and quality, improve nutrient utilization efficiency and increase income; increase yield by 200-280 kg / mu (8-11% respectively) compared with farmers' customary fertilization, save fertilizer cost by 1500-1800 yuan / mu, and increase income by 2086-2713 per mu The use efficiency of nitrogen fertilizer is increased by 76-153%, and the carbon emission per unit area is reduced by 0.51-0.83 tons / mu (36-75% respectively). Moreover, the special fertilizer for pomelo has a simple fertilization method and a reasonable fertilization position, which has a high Practical application value
