This invention discloses a method for producing crop cultivation substrate using sugarcane filter mud and sugarcane pith as main raw materials, comprising the following steps: (1) dissolving and diluting 4,5-dihydro-4,5-dioxo-1H-pyrrolo[2,3-f]quinoline-2,7,9-tricarboxylic acid in water to obtain a solution; (2) mixing sugarcane slurry, sugarcane pith, the 4,5-dihydro-4,5-dioxo-1H-pyrrolo[2,3-f]quinoline-2,7,9-tricarboxylic acid solution, fermentation agent, and improver, adjusting the moisture content, and then composting and fermenting. The compost is turned over every few days and continuously composted and fermented for several days to obtain the crop cultivation substrate. The crop cultivation substrate produced by this invention is of excellent quality, allowing direct planting of plants without root burn. Therefore, this invention, using sugarcane filter mud and sugarcane pith as main raw materials to prepare and produce crop cultivation substrate, can effectively solve the problem of comprehensive utilization of sugarcane filter mud and improve product sales.

The invention belongs to the technical field of crop fertilization, and particularly relates to a triangular fertilization method for sugar cane. Sugarcane is subjected to triangular fertilization, the sugarcane is divided into newly-planted sugarcane and perennial root sugarcane, triangular fertilization is carried out on the newly-planted sugarcane, top corner sugarcane ditch fertilization is carried out when the newly-planted sugarcane is planted, the fertilization depth is 5-10 cm, bottom corner fertilization is carried out along the middle position of a sugarcane row in the tillering stage of the sugarcane, and the fertilization depth is 30-35 cm; triangular fertilization is carried out on the perennial root sugarcanes, one-time triangular fertilization is carried out within 7 days after the sugarcanes are harvested or at the tillering stage of the perennial root sugarcanes, the fertilization depth of the 1 / 2 position of each sugarcane row is 30-35 cm, and the fertilization depth of the 1 / 4 position and the 3 / 4 position of each sugarcane row is 15-20 cm. The precise soil layer fertilization method provided by the invention has the advantages that the fertilization of sugar cane is more efficient and more environment-friendly, and farmers are helped to increase income.

The present application relates to the technical field of microorganism, and particularly relates to a paste-like Paenibacillus sp. HX-02 and application of the paste-like Paenibacillus sp. HX-02 in promoting crop growth. The preservation number of the paste-like Paenibacillus sp. HX-02 is CGMCC No. 30949. The application includes: improving one or more of plant height, branch number, weight or quantity of crops. The present application screens and separates a paste-like Paenibacillus sp. HX-02, which can decompose soil mineral lattice structure to release K, Fe, Mg, Si, Al and Mo, secrete cytokinin, gibberellin, kinetin, indole acetic acid and acetylsalicylic acid, promote crop growth, improve crop yield, and has important application value in the field of agricultural development.
