The invention discloses a granular bio-fertilizer and a preparation method thereof, and the granular bio-fertilizer comprises the following components in percentage by weight: 94-97% of a base fertilizer, 2-5% of a synergist and 1-2% of an auxiliary agent. The granular bio-fertilizer is a fertilizer prepared by compatibility of one of an inorganic fertilizer, an organic fertilizer and an organic and inorganic fertilizer with a bio-fertilizer synergist. The granular bio-fertilizer disclosed by the invention can adopt an inorganic fertilizer, an organic fertilizer or an organic and inorganic fertilizer as a base fertilizer, can be suitable for almost all granular fertilizers (except for fertilizers with a killing function on microorganisms or an antagonistic effect on components in a bio-fertilizer synergist) in the current market, and is simple in production process, relatively low in cost and suitable for industrial production. Moreover, the added value of the product can be effectively improved, and the production process belongs to a novel fertilizer production process and has a huge market popularization value.

The application discloses a planting method for improving tobacco quality, and the fertilization mode of the planting method is set as T3, or T4, or T5. The fertilization treatment is beneficial to tobacco plant growth, tobacco carbon and nitrogen metabolism, tobacco leaf quality, and improves tobacco leaf yield.

This invention relates to the field of integrated water and fertilizer irrigation and rhizosphere microbial regulation technology in agriculture, and discloses a device for regulating rhizosphere soil microorganisms in asparagus based on integrated water and fertilizer management. The device includes a substrate feeding hopper, a first auxiliary agent supply mechanism, a second auxiliary agent supply mechanism, and a turnover mixing chamber. The substrate feeding hopper is connected to a discharge transition cylinder at its bottom, which then communicates with the turnover mixing chamber. The first auxiliary agent supply mechanism outputs multiple guide pipes and connects to an underground drip irrigation network. A double-layered composite spiral propulsion blade is installed in the turnover mixing chamber to achieve solid-liquid kneading and mixing. The second auxiliary agent supply mechanism connects to the mixed liquid outlet component through a liquid phase pipeline to complete secondary confluence. This invention avoids elemental antagonism through multi-channel independent delivery, constructs a microbial carrier through deep solid-liquid mixing, and improves rhizosphere moisture uniformity through a spiral drip irrigation structure, significantly enhancing fertilizer utilization efficiency and the activity of the asparagus rhizosphere microecological environment, achieving a synergistic effect of water and fertilizer conservation with increased yield and quality.

The utility model provides a distributed sintering system, which relates to the technical field of iron and steel smelting, and comprises a sintering machine and a master control center, the sintering machine is divided into a plurality of areas along the trolley advancing direction of the sintering machine, and a plurality of air boxes, flue gas pipelines and control devices are independently arranged in each area; a traditional large-flue, high-negative-pressure and high-air-volume induced draft sintering technology is improved, in the production process, the needed air volume and air pressure are different, and the traditional large-flue technology is difficult to adjust accurately, and a multi-flue, low-air-volume and low-negative-pressure collecting and distributing type sintering system is adopted, so that the energy consumption is reduced, and the energy consumption is reduced. Adjustment and control can be carried out according to flue gas characteristics and production requirements of different areas in the sintering process, the production quality can be effectively improved, the production energy consumption can be greatly reduced, the unit sinter pollutant emission amount and the total sintering flue gas emission amount are reduced, and a brand new energy-saving and emission-reducing sintering production process is provided for metallurgical production.
