Assist in organic vegetable cultivation

Various parts of Guizhou Province have entered the period of picking prickly pear, and Guizhou Haike Industrial Development Co., Ltd., a subsidiary of Guiyang Agricultural Investment Group, has also entered a busy process of fruit harvesting and juice extraction. With the continuous progress of juice extraction work, the pile of prickly pear residue on the open space outside the workshop is particularly eye-catching. Now, these tons of prickly pear residue are no longer a headache. After being “reprocessed”, they will become green fertilizers and continue to play a positive role in vegetable cultivation, realizing the transformation of waste into treasure, which is both ecological and environmentally friendly. Currently, this technology has been fully applied, and it has also opened up new directions for the development of the entire prickly pear industry chain.

Former waste, current fertilizer, “said Yang Xuan, the chief craftsman of Guizhou Haike Company. This is one of the transformation achievements of the” Key Technology Research and Pilot Test of Cili Residue Fertilization Application “project jointly carried out by Guiyang Agricultural Investment Group and Guizhou University. It is reported that in 2021, Guizhou Haike Industrial Development Co., Ltd., a subsidiary of Guiyang Agricultural Investment Group, signed a cooperation agreement with Guizhou University on the “Key Technology Research and Pilot Test of Cili Residue Fertilization Application” project. Currently, the bio organic fertilizer and biochar based organic fertilizer developed in this project have been tested in the field and have achieved results.

It is reported that after the establishment of the “Key Technology Research and Pilot Study on the Fertilization Application of Rosa roxburghii Residue” project, research and development on the fertilization technology of Rosa roxburghii residue will be carried out. Through the implementation of this project, key technologies such as pre-treatment of Rosa roxburghii residue, carbonization of Rosa roxburghii seeds, screening and optimization of biological strains for Rosa roxburghii residue composting, rapid composting of Rosa roxburghii residue in a tank, and preparation of new carbon based active organic fertilizer will be completed, We have developed research contents such as operating procedures and production process technologies for the production and processing of prickly pear residue organic fertilizer. We have solved key technologies for prickly pear residue pretreatment, screening and optimization of biological strains in prickly pear residue composting, rapid composting in prickly pear residue tank, and pilot production and sales of prickly pear residue organic fertilizer products.

Among them, in combination with the fertilization requirements of Guiyang Agricultural Investment Group’s 10000 mu high standard vegetable supply base, this project focuses on conducting research on the pilot production and processing operating procedures and standards of prickly pear residue matrix organic fertilizer. In terms of the development of organic fertilizer for prickly pear residue, bio organic fertilizer and biochar based organic fertilizer have been developed, and the two began field trials in November 2021. A field experiment was conducted to investigate the effects of organic fertilizer from prickly pear residue on the yield and quality of Chinese cabbage and peacock vegetable. The results showed that applying prickly pear residue bio organic fertilizer and prickly pear residue biochar based organic fertilizer separately, compared with conventional composite fertilizer, prickly pear residue organic fertilizer can help activate the soil, reduce fertilizer usage, and significantly improve the yield and quality of Chinese cabbage and peacock vegetable. “Yang Xuan said that in the process of promoting the project, Guizhou University was responsible for technical summary and talent cultivation, Guizhou Haike Industrial Development Co., Ltd. is responsible for industrialization implementation and application promotion. This is the result of cooperation between enterprises and Guizhou University, achieving a strong alliance between enterprises and universities.
