The present invention aims to provide a weed control method using acetic acid bubbles that, by remaining in the soil, disrupt the growth mechanism of plants, weakening them and leading to their death. Furthermore, it aims to provide a weed control method and weed treatment device using acetic acid bubbles that are highly safe for humans and animals. [Solution] In order to solve the above problems, the present invention provides a weed treatment method using acetic acid bubbles, which is a method of weakening the growth of weeds or killing plants using a herbicide, characterized in that a herbicide containing brewing acetic acid, a surfactant, and water is sprayed onto soil where weeds are abundant in the form of countless bubbles.

The invention discloses an agricultural soil disinfection machine. The agricultural soil disinfection machine comprises a support, trundles, a push rod, a handrail, a driving box and a soil disinfection mechanism and further comprises a steam generation mechanism, and the steam generation mechanism is used for providing high-temperature and high-pressure steam for the soil disinfection mechanism; the steam generation mechanism comprises a boiler and a heater, the heater is used for heating water in the boiler to generate high-temperature and high-pressure steam, and an exhaust pipeline of the boiler is connected with the soil disinfection mechanism through a control valve. According to the agricultural soil disinfection machine, the steam generation mechanism and the auxiliary disinfection mechanism are arranged, high-temperature steam generated by the steam generation mechanism is supplied to the soil disinfection mechanism and the auxiliary disinfection mechanism for use, original hot water is replaced, water can be saved, the disinfection effect can be improved, and the local soil disinfection effect is emphatically enhanced; the subsequent seeding is convenient.

The invention discloses a rhododendron seed soaking agent and a rhododendron seedling raising method, and relates to the field of plant propagation, the rhododendron seed soaking agent comprises the seed soaking agent, the seed soaking agent is a solution with the concentration of 0 MPa, the solution takes water as a solvent, no other chemical substances are added, and the solution is used for soaking rhododendron seeds to promote germination of the rhododendron seeds; according to the rhododendron seed soaking agent and the rhododendron seedling raising method, healthy and full rhododendron seeds without plant diseases and insect pests are selected, it is ensured that the seeds have normal physiological activity, a good foundation is laid for smooth proceeding of subsequent germination and seedling formation, and the success rate of seedling raising is increased from the source; the soaking time is determined according to the sizes and characteristics of the seeds, so that the seeds of different sizes can fully absorb water and effective components in the seed soaking agent, the internal physiological activities of the seeds are activated, and the germination rate and the seedling rate are increased; a suitable physical and chemical environment is provided for seed germination and seedling growth.

Device for the thermal treatment of bulk material, which has: • a multi-tiered frame (G) made of tubular frames (RR), in which a drum body (T) with mixing blades (M) is mounted on the lower support frame (T1) and a vibrating screen (A) is arranged on the support frame (T2) located at a distance above it, • a chute (RU) for feeding the pre-sieved mix to a drum opening (E) of the drum body (T), • a gas burner (B) arranged outside the drum body (T), the flame of which extends into the interior of the drum body (T) and • a baffle plate (PB) arranged inside the drum body (T) above the flame.

This invention discloses a composite microwave soil disinfection device and its operation method, relating to the field of plant protection machinery. The soil disinfection device is configured as a soil operation device based on microwave and micro-steam synergy. The soil operation device includes a carrier and a micro-steam synergy mechanism. The carrier is a self-propelled tracked chassis. A lidar for environmental perception and navigation is installed on the front of the carrier, and a support frame that can extend laterally is provided on the rear of the carrier. The microwave irradiation mechanism is located on the rear of the carrier and performs microwave disinfection on the soil during movement. The microwave irradiation mechanism has a high-voltage power supply unit electrically connected to the carrier and a microwave irradiation component. The microwave irradiation component is mounted on the support frame and includes an irradiation assembly and a heat dissipation module. This composite microwave soil disinfection device and its operation method achieve efficient soil sterilization through the synergistic disinfection mechanism of microwave heating and micro-steam.

The application discloses a nutrient soil sterilization and killing device for soil treatment, which comprises a sterilization and killing cavity and a plurality of sterilization wheels rotatingly arranged in the sterilization and killing cavity. The sterilization wheel is internally provided with a cavity, and a plurality of dispersion columns are arranged in the cavity. A communicating port is arranged on the peripheral wall of the cavity. The top of the sterilization and killing cavity is provided with a nutrient soil feeding port, the bottom is provided with a nutrient soil discharging port, and the left and right sides are provided with steam inlets. Compared with the traditional sterilization and killing device, the nutrient soil can be fully dispersed without the need of additionally arranging a dispersion mechanism driven by some energy source, so that the energy consumption for treating the nutrient soil is reduced. In addition, the interior of the sterilization wheel is in a circular structure. When the steam enters the interior of the sterilization wheel, the steam can be dispersed in the interior of the cavity of the sterilization wheel. Due to the action of the dispersion columns, the steam can be further mixed in the interior of the cavity, so that the steam can be more fully contacted with the nutrient soil, and sufficient sterilization is realized.
