Effects Of Precision Fertilization Management On Yield And Quality Of Watermelon And Melon

Cultivation of watermelon and melon has a long history in China,and it occupies an important position in the development of the global industry.The economic benefit of watermelon and melon occupie a very important position in Chinese planting industry,and their unit area yield is about four times that of other planting industry.However,there is still a lot of blindness in fertilization in the production of watermelon and melon.Excessive or unreasonable fertilization not only causes a large amount of waste of fertilizer resources,increases production costs,affects watermelon quality,and also causes environmental pollution.Therefore,accurate and reasonable fertilization is essential for improving quality and yield of watermelon(melon)and promoting sustainable development of green agriculture.In this study,watermelon cultivars Jinlvhongling,Jinlujiali 2,Xiuli and melon cultivar Zaotian 5 were selected as the experimental material.The experimental sites lacated in Anhui Lvxizhou Agricultural Technology Development in Feixi County,Shucheng Agricultural Science Research Institute and Shenxiang town in Wuhu.Set up different fertilization management for watermelon(melon),comparing with farmers’ habitual fertilization management(FP).Then explore the precise and high-efficient fertilization management for watermelon(melon).According the determination results of nutrient absorption and utilization,yield and quality indexes of watermelon(melon)during the growth period,the reaserch shows: the precise fertilization can improve the nutrient absorption and utilization efficiency of watermelon(melon),thereby increase the yield and maintain or improve fruit quality.The optimized fertilization management modes in this study possess favorable practical and application value in the production.Secondly,it is also necessary to consider the difference in fertilizer efficiency between varieties.In this study,Jinlvhongling,Jinluzaojia 2 and Zaotian 5 can improve resource utilization efficiency and create great economic and environmental benefits by optimized fertilization management.Within the scope of this study,the optimal treatment of fertilization management with 300 kg of biochar livestock manure organic fertilizer(silte organic fertilizer)+ 18-7-20 compound fertilizer(35 kg of watermelon and 30 kg of melon)as base fertilizer and 20 kg of 16-6-30 water-soluble fertilizer as topdressing has the best effect.
