This invention discloses an adenine-based heat stabilizer and its application in PVC composites, belonging to the field of heat stabilizer technology. The heat stabilizer is an adenine-based substance or a compound of an adenine-based substance and an auxiliary stabilizer. The adenine-based substance is adenine or adenine nucleoside, and the auxiliary stabilizer is at least one of calcium salt stabilizers, zinc salt stabilizers, and polyol stabilizers. This adenine-based heat stabilizer can improve the initial whiteness of PVC and impart better long-term stability to PVC. Its application in PVC composites can effectively improve the thermal stability and mechanical properties of PVC composites, possessing practical application value.

The utility model belongs to the technical field of acid soil improvement, and particularly relates to an acid soil improvement device for agricultural planting, which comprises a U-shaped frame. A group of connecting rods are arranged at the bottom end of the U-shaped frame, and the bottom ends of the connecting rods are fixedly connected with soil ploughing cutters; the overlook cross section of the ploughing cutter is an isosceles triangle, and the inclined surfaces on the two sides of the ploughing cutter are arc-shaped; a first groove is formed in the bottom end of the ploughing cutter; a spray head is mounted in the first groove; a hose is arranged on the spray head; a liquid box is fixedly connected to the side wall of the U-shaped frame; a cover plate is mounted at the top end of the liquid box through bolts; the top end of the cover plate is fixedly connected with a feeding pipe; a discharging pipe is arranged on the side wall of the liquid box; valves are arranged on the discharging pipe and the feeding pipe; the utility model provides an acid soil improvement device for agricultural planting, aiming at solving the problem that the improvement effect is greatly influenced because a modifier is difficult to immerse into soil under the influence of high-temperature weather or harder soil.

This invention discloses a high-humicity microbial fertilizer and its preparation method, belonging to the field of microbial fertilizer technology. The method involves adding a mixed carrier, a protective agent, and fermentation broth to a stirred tank in a specific ratio, followed by shaking and adsorption, filtration, and drying with forced air until the moisture content of the absorbent resin powder reaches 30-35%. The powder is then continuously granulated using a granulator and sieved to obtain microbial agent granules with a particle size of 2-5 mm. The microbial agent granules and sodium humate are mixed at a mass ratio of 1-2:10 to obtain the high-humicity microbial fertilizer. The aggregated short fibers, under the adhesive and physical entanglement effects of the protective agent, increase the internal space of the microbial agent granules while improving structural stability, providing a stable growth and reproduction environment for microorganisms, and improving the long-term storage of the fertilizer and the survival rate of microorganisms after application. The enlarged microbial agent granules provide support, increasing soil looseness and providing a good respiratory environment for crop roots.

The utility model provides a chestnut garden soil improvement deep ploughing device. The chestnut garden soil improvement deep ploughing equipment comprises a supporting plate, a box body is fixedly mounted at the top of the supporting plate, and a balancing weight is arranged in the box body; the sliding rod is installed on the supporting plate in a sliding mode, and a fixing block is fixedly installed at the bottom end of the sliding rod; the sleeve shell is fixedly installed on the fixing block through a bolt, and a deep ploughing plough used for improving the soil of the Chinese chestnut garden is fixedly installed on the sleeve shell. The chestnut garden soil improvement deep ploughing device solves the technical problems that due to the fact that an existing deep ploughing device cannot conduct fertilization in the soil ploughing process, fertilization needs to be conducted additionally or manually if fertilization needs to be conducted after deep ploughing, and then the soil improvement efficiency is affected.
