This invention discloses a green control method for tomato viral diseases based on the synergistic effect of Solanaceae and Asteraceae weeds, belonging to the field of agricultural plant crop protection technology. This invention uses the Solanaceae weed *Solanum nigrum* and the Asteraceae weed *Chrysanthemum indicum* as indicator plants for tomato viral diseases. By arranging the indicator plants in a grid pattern, comprehensive monitoring of major viral disease species within the facility can be achieved. By monitoring the viral disease symptoms of the indicator plants, early warnings can be issued 7-10 days in advance, allowing more time for tomato disease control and improving the timeliness and proactivity of prevention and control. Furthermore, based on the warnings issued by the indicator plants, an extract of *Eupatorium fortunei*, an Asteraceae weed that has a significant inhibitory effect on tomato viral disease symptoms, is applied, thus constructing an integrated "monitoring-blocking" green control system, achieving early warning and efficient control of viral diseases.

The present application relates to a kind of for cadmium and tetracycline complex pollution repair in water body biological carbon material and its preparation and application, belong to water pollution repair technical field.It includes steps: (1) take fungus and nightshade after the joint repair cadmium contaminated soil nightshade plant plant tissue, after washing, drying and grinding, obtain nightshade plant tissue powder;(2) nightshade plant tissue powder is pyrolyzed 1-3h under 400-600 ℃, cooling to 20-30 ℃, after grinding, obtain the biological carbon material for cadmium and tetracycline complex pollution repair in water body.The present application first uses fungus and nightshade after the joint repair cadmium contaminated soil nightshade plant plant tissue as the raw material of biological carbon material, realizes the resource utilization of contaminated soil repair plant.Both solve the disposal problem of plant after contaminated soil repair, and avoid the consumption of additional resources, greatly reduce the cost of sewage treatment.

The present application belongs to the field of soil remediation, and particularly relates to a method for remediation of cadmium contaminated soil. The specific technical scheme is as follows: a soil remediation method comprises the following steps: before planting economic crops, applying sulfate-reducing bacteria to the soil to be remediated; after harvesting the economic crops, planting cadmium extraction crops in the soil to be remediated. The present application provides a water-flood rotation soil remediation method which can produce while remediation. On the one hand, the biological passivation can reduce the biological availability of cadmium in the soil, thereby reducing the stress of cadmium on plants and the absorption and accumulation of cadmium by plants; on the other hand, the biological technology can strengthen the ability of nightshade to extract cadmium, thereby extracting cadmium in farmland soil.

The utility model provides a weeding structure of a weeding machine, relates to the technical field of weeding machines, and is suitable for preventing and removing agricultural alien invasive plants such as tribulus terrestris, solanum rostratum and barley grass. Comprising a weeding machine body, a baffle is fixedly installed on the side face of the weeding machine body through bolts, a protective cover and a driving motor are fixedly installed on the outer surface of the weeding machine body, a first gear is fixedly installed at the output end of the driving motor, a fixing base and a shaft sleeve are fixedly installed on the inner surface of the weeding machine body, and a rotating rod is rotationally connected to the surface of the fixing base; according to the cutting device, through the arrangement of the fixing groove, the fixing block, the spring, the limiting rod and the pulling plate, the damaged cutting disc can be rapidly replaced and installed, the replacement time is greatly shortened, the operation efficiency is improved, meanwhile, through the cooperation of the threaded sleeve and the fixing sleeve, the cutting disc can be rapidly replaced and installed, and the cutting disc can be rapidly replaced and installed. And the groove and the pulling plate are accurately butted, so that the supporting force is enhanced, and the cutting disc is ensured to be stable and shake-free during high-speed operation.

The utility model discloses a carbon dot slow release type black nightshade cultivation container, and relates to the technical field of black nightshade cultivation. The device comprises a cultivation mechanism, an extension mechanism is detachably arranged at the top end of the cultivation mechanism, the cultivation mechanism comprises a cultivation pot body, a slow-release pot body is integrally formed at the bottom end of the cultivation pot body, and a carbon dot slow-release part and a cadmium ion adsorption filter screen which are used in a matched mode are detachably arranged on the inner side of the slow-release pot body. Arc-shaped blocks which are symmetrically distributed are integrally formed on the cadmium ion adsorption filter screen, concave holes which are matched for use are formed in the opposite sides of the two arc-shaped blocks, and a temperature and humidity response film which is matched for use is arranged outside the carbon dot slow release part. Through the arrangement and use of the cultivation mechanism, the carbon dot release rate can be controlled in cooperation with the temperature and humidity response film, the purpose of degrading a high polymer material is achieved, continuous supply of the carbon dots in the cadmium-contaminated soil and secondary blocking of cadmium ions can be achieved at the same time, and in addition, convenience is provided for disassembly, assembly and replacement of a cadmium ion adsorption filter screen and a carbon dot slow release part.

The invention relates to a nitrogen regulation cultivation method for improving alkaloid content of black nightshade green fruits, and belongs to the technical field of planting. A nitrogen regulation cultivation method for increasing alkaloid content of black nightshade green fruits comprises the steps that mixed nitrogen fertilizer containing ammonium nitrogen and nitrate nitrogen is applied to black nightshade plants in stages, and the molar ratio of the ammonium nitrogen to the nitrate nitrogen is 7: 3-3: 7 according to the nitrogen element. The cultivation method is simple in application and low in cost, and the cultivation fertilization mode can remarkably promote the content of solasonine and solamargine in the black nightshade green fruits, so that high-quality medicinal black nightshade fruit resources are obtained.
