The utility model relates to the technical field of soil monitoring, and provides a soil water content monitoring and processing device which comprises a bottom plate and two circular rings, the top of the bottom plate is fixedly connected with a supporting rod, and the two circular rings are fixedly connected to the outer surface of the supporting rod. According to the device, the protective net can be installed by rotating the screw rod with hands and limiting the arc-shaped block, the protective net has certain elasticity, when the wild boars and other animals run around in crop land, the wild boars and other animals are blocked and buffered through the protective net, when the wild boars and other animals touch the protective net, the first pull rope and the first bell shake, and therefore the wild boars and other animals can be prevented from falling off. The bell rings to drive animals such as wild boars, so that the situation that the animals such as the wild boars directly touch the monitoring and processing device, damage to the monitoring and processing device and bite damage of a part of exposed wires can be avoided, and the situation that the animals such as the wild boars are injured due to collision can also be avoided.

The application discloses a kind of multiscale unmanned aerial vehicle image monitoring crop growth methods and systems, belong to agricultural remote sensing and intelligent monitoring technical field.The method of the present application comprises: controlling unmanned aerial vehicle to collect target area low-resolution remote sensing image at first height;Based on first identification model, crop land boundary is extracted and divided into multiple grids;The health index of each grid is calculated, and the center point of the abnormal grid is located based on the statistical threshold value;Control unmanned aerial vehicle to descend to second height and fly to the top of abnormal grid to carry out leaf scale high-resolution imaging;High-resolution image is input into second identification model, and output fine diagnosis results such as water shortage, lack of fertilizer, disease and pest.The present application realizes the organic combination of large-scale rapid screening and local accurate diagnosis through two-level scale cooperative monitoring, greatly improves the efficiency and accuracy of crop growth monitoring, and is suitable for field crop automation, intelligent growth management.

The utility model relates to the technical field of drip irrigation watering, and particularly discloses a drip irrigation device which comprises a water pump, a connecting device connected to the water pump and two drip irrigation belts installed on the connecting device. The two drip irrigation belts are movably connected with the connecting device; the compass type design is adopted on the whole, the two drip irrigation belts are installed on the connecting device, in the using process, the two drip irrigation belts can be placed above crops or on one side of the crops for drip irrigation operation, in the cultivating or weeding process, the two drip irrigation belts can be moved away from the crop land like two feet of a compass, and therefore the two drip irrigation belts can be conveniently used. Therefore, during cultivation or weeding, the drip irrigation tape cannot be touched, and the drip irrigation tape is prevented from being damaged by machinery; meanwhile, the water outlet device can adjust the position of the drip irrigation nozzle through rotation of the gear ring on the connecting pipe according to the position of the crops, the drip irrigation nozzle is just out of the position above the crops, and therefore the problem that an existing drip irrigation device can only conduct drip irrigation through drip irrigation holes is solved.

The invention provides application of bacillus licheniformis and a compound microbial agent in prevention and control of peanut fruit rot, and belongs to the technical field of microbial agents. The strain and the compound microbial agent provided by the invention have a remarkable and stable prevention and control effect on peanut fruit rot, can effectively reduce the occurrence of diseases, reduce the loss of pods, and remarkably improve the yield and quality of peanuts; the microbial agent can still play a significant prevention and control effect when applied at the initial stage of peanut fruit rot, breaks through the limitation that prevention focuses on treatment in the prior art, and provides a brand-new green prevention and control scheme for safe production of peanuts. The application is beneficial to reduction of chemical pesticide application, protection of farmland ecological environment and promotion of soil health and agricultural sustainable development, meanwhile, the method is easy and convenient to operate and wide in applicability, especially has application value on continuous cropping land parcels, and has remarkable economic, ecological and social benefits.
