Yishizhuangs Special Fertilizer for Tubers Wins Affirmation from Experts Again in Enshi Yield Measurement

Potato is the fourth - largest food crop in China and also a key development industry in Hubei Province. In recent years, in order to accelerate the industrial layout and promote poverty alleviation, Enshi Prefecture has seized the opportunity to turn potatoes into a characteristic industry for getting rich. The small potatoes have transformed into "little golden beans".

On July 3rd, in order to promote the scientific fertilization technology for potatoes and achieve high - quality and high - yield potatoes, the "On - site Acceptance Meeting of the Demonstration of High - Efficiency Fertilization Technology for Potatoes in the Whole Province" hosted by the Hubei Fertilizer Application Association and undertaken by Huazhong Agricultural University and the Enshi Prefecture Academy of Agricultural Sciences was held in Lichuan.

The Hubei Fertilizer Application Association organized multiple units including the Key Laboratory of Potato Biology and Biotechnology of the Ministry of Agriculture, the Hubei Provincial Cultivated Land Quality and Fertilizer Workstation, the Hubei Rape Office, the Enshi Tujia and Miao Autonomous Prefecture Bureau of Agriculture and Rural Affairs, the Enshi Tujia and Miao Autonomous Prefecture Academy of Agricultural Sciences, and the Lichuan Bureau of Agriculture and Rural Affairs to conduct an on - site inspection and acceptance of the thousand - mu demonstration field of the special fertilizer for tubers jointly developed by Huazhong Agricultural University and Hubei Yishizhuang Agricultural Technology Co., Ltd. on potatoes in Lichuan City.

After measurement, the average mu yield of 80 kg of 40% (24 - 7 - 9) fertilizer applied by farmers in conventional fertilization is 1475.7 kg, and the average mu yield of 80 kg of 40% (14 - 8 - 18) of Yishizhuang's special fertilizer for tubers is 1693.7 kg. The effect is significantly better than that of conventional fertilization, which has been unanimously recognized by the expert group, and it is recommended to increase the promotion and application.

The participating experts believe that the integrated technology of high - efficiency fertilization for potatoes has three technical advantages, namely substituting and reducing chemical fertilizers, precise fertilization, and improving fertilizer efficiency. It is necessary to deeply explore the integrated technology model of "two fertilizers + three agents" for high - efficiency fertilization and soil improvement, that is, the integrated technology model of "formula fertilizer + organic fertilizer + soil conditioner + microbial agent + nutrient synergist", to promote the potato industry to a new level.
