Scientific Fertilization Brings Obvious Benefits: Yishizhuang Helps in Reducing Fertilizer Application and Increasing Efficiency

Citrus is one of the leading industries in Yichang, Hubei Province. In order to promote the healthy cultivation of citrus with the "Three Increases and Three Decreases" and observe the technology of reducing chemical fertilizer application and increasing efficiency for citrus, on October 16, 2021, an expert team composed of Director Zhao Tongke from the Beijing Academy of Agriculture and Forestry Sciences, Vice President Liu Jianjun from the Sichuan Academy of Agricultural Sciences, Director Chen Guoqing from the Zhejiang Citrus Research Institute, Director Bao Jiangfeng from the Fruit and Tea Office of the Hubei Provincial Department of Agriculture and Rural Affairs, and Deputy Director Huang Heping from the Hubei Provincial Station for Cultivated Land Quality and Fertilizer Work conducted on - site yield measurement and quality evaluation of the comparative experiment and demonstration of Yishizhuang's special fertilizer for citrus at the Demonstration Farm of Famous, Special and High - quality Fruits of the Agricultural Development Co., Ltd. in the Middle and Lower Reaches of the Yangtze River, which was carried out by Huazhong Agricultural University, the Comprehensive Experimental Station of Loose - skinned Citrus in Yichang, Hubei Province, and Hubei Yishizhuang Agricultural Technology Co., Ltd. Among them, Director Xie Heping of the Comprehensive Experimental Station of Loose - skinned Citrus in Yichang introduced the overall situation of the project implementation in the past three years, and Director Zhou Jianjun of the Fruit Demonstration Farm shared the changes brought by scientific fertilization over the years.

After the on - site evaluation, the expert group organized a special meeting to discuss the overall situation of the project implementation and put forward valuable suggestions from aspects such as reducing chemical fertilizer application, organic substitution, technical integration, school - enterprise cooperation, and achievement transformation. Finally, Professor Hu Chengxiao, an expert from Huazhong Agricultural University and the National Citrus Industry Technology System, gave a special report on the fertilization technology for citrus. Professor Hu introduced the main problems existing in current citrus fertilization, deeply analyzed the research and development background and product characteristics of the special fertilizer for citrus, and demonstrated the achievements obtained since the technical cooperation with Hubei Yishizhuang Company, which was unanimously recognized by the experts present.

It is understood that the demonstration project of Yishizhuang's special fertilizer for citrus has been implemented since 2019. By implementing the package fertilization plan of "special fertilizer + organic fertilizer", according to the soil conditions in Guanzhuang and the nutritional needs characteristics of mandarin oranges, it is recommended to apply fertilizer twice a year. Apply the base fertilizer from late February to early March in spring, applying 3 jin of Yishizhuang 35% (15 - 7 - 13) special fertilizer for citrus per plant and an additional 6 jin of Yishizhuang organic fertilizer per plant; apply the fruit - strengthening fertilizer in early June in summer, applying 2 jin of Yishizhuang 35% (15 - 7 - 13) special fertilizer for citrus per plant.

Compared with the past farmers' habitual fertilization, the technology of reducing chemical fertilizer application and increasing efficiency has received the active response and support of local growers. The demonstration scale has developed from 55 mu in the past to 175 mu nowadays, enabling the demonstration households and surrounding users to deeply feel the advantages and economic benefits brought by scientific fertilization.

Yishizhuang's package fertilizer for citrus provides full nutrition for crops, serves as a good helper for users, reduces fertilizer application, increases production and improves quality, improves the soil, increases efficiency and brings in profits!
Results of On - site Yield Measurement and Quality Evaluation

1.Through the on - site comparative experiment, 5 Satsuma mandarin orange trees were randomly selected for yield measurement of fruits, and the quality was significantly improved.

2.After years of multi - point experimental demonstrations, the implementation of the technology of reducing chemical fertilizer application and increasing efficiency for Satsuma mandarin oranges mainly with "Yishizhuang's special fertilizer for citrus + organic fertilizer" has alleviated the environmental problems caused by excessive fertilization, unreasonable fertilization, and fertilizer loss.
