The invention relates to the technical field of satellite-ground laser communication, and discloses a banyan-shaped network communication method and system based on multi-beam multipath transmission and space diversity synthesis aperture reception. The method comprises the following steps: dividing a light beam into a plurality of beams at a satellite-based terminal through beam forming to point to a plurality of ground stations; multiple ground stations receive data in parallel and then gather the data to a data center for time-space synchronization; and the data center adopts a multi-branch neural network to intelligently fuse the synchronized data so as to reconstruct a signal. According to the invention, by constructing the satellite-to-ground collaborative architecture, signal interruption and data loss caused by atmospheric turbulence are effectively suppressed, the limitation of high-error-code communication is broken through, and remote, high-speed and high-reliability satellite-to-ground communication is realized.

The invention relates to the technical field of landscape bridges, and discloses an arch-shaped cable-stayed combined beam column structure and a construction method of the arch-shaped cable-stayed combined beam column structure. The middle of the main beam is connected with the top of the pier column; a main arch ring; the number of the arch feet is two, the two arch feet are arranged at the two ends of the main arch ring respectively, and the arch feet are connected with the two ends of the main beam respectively; a first web member; when loads such as a vehicle are generated on the top face of the main beam, horizontal thrust independently balanced by the axial tension of the main beam is offset by the bending moment and the shearing force of the pier column; the main arch ring connected with the web member exerts upward supporting force on the main beam, large hogging moment is prevented from being generated at the joint of the main beam and the pier column in the T-shaped structure, the main beam, the pier column, the main arch ring and the web member form a beautiful shape similar to a big banyan tree on the vertical face, and the comprehensive performance of large span, low height, high adaptability and unique landscape effect is achieved.

The invention discloses a ficus microcarpa root irrigation and fertilization device and method for urban landscaping, belongs to the related technical field of landscaping tree maintenance, and discloses a ficus microcarpa root irrigation and fertilization device and method for urban landscaping, the ficus microcarpa root irrigation and fertilization device for urban landscaping comprises a self-propelled vehicle located on the ground, and one side of the top end of the self-propelled vehicle is fixedly provided with a large support; an irrigation and fertilization treatment assembly is installed on the large support, a three-legged suspension support is fixedly installed on the other side of the top end of the self-propelled vehicle, a gear motor is fixedly installed at the top end of the three-legged suspension support, and a drilling irrigation assembly is installed at the bottom end of the three-legged suspension support. Directional irrigation and fertilization of banyan root systems in urban landscaping can be achieved, the growth direction of the banyan root systems can be controlled, and the situation that when the banyan root systems grow, gas, water, electricity, a net and other pipelines are buried on a hardened road surface or underground is affected is avoided.

The invention belongs to the technical field of navigation communication antennas, and particularly discloses a miniaturized multi-band composite antenna, which comprises a ring focus reflector antenna, a banyan array antenna and a frequency selective surface, the ring focus reflector antenna comprises a main reflector, an auxiliary reflector and a multi-ripple feed source, the concave surface of the main reflector is opposite to the convex surface of the auxiliary reflector, and the multi-ripple feed source is arranged at the axis of the main reflector. According to the miniaturized multi-band composite antenna and the assembly thereof provided by the invention, multi-band efficient radiation is realized in a limited space through cooperative layout of the ring focus reflector antenna, the special-shaped array antenna and the frequency selective surface in combination with optimal design of the multi-ripple feed source and the banyan antenna group, and meanwhile, inter-band interference is suppressed by using the frequency selective surface, so that the antenna efficiency is improved. The antenna has the advantages of compact structure, excellent multi-band cooperative work performance and strong electromagnetic compatibility.

The invention discloses a breeding device and method for small fig bee larvae, and relates to the technical field of small fig bee larva breeding. The breeding equipment comprises a main supporting column, a supporting frame fixed to the top of the main supporting column and artificial ficus microcarpa, a solar panel for providing energy is fixed to the top of the supporting frame, the supporting frame is covered with tarpaulin, a door curtain is installed on the front face of the tarpaulin, and the door curtain is connected with the main supporting column. The door curtain is provided with a protection assembly for changing the invasion rate of the parasitoid wasps, a driving assembly for removing the parasitoid wasps invading into the tarpaulin is arranged in the tarpaulin, abnormal behaviors or physiological pressure caused by an artificial environment is reduced, and the device can be used for conservation of endangered banyan trees or pollination bees in urban greening or help to recover a damaged pollination network. The negative influence caused by climate change is relieved, a quantitative technical standard is provided for cultivation of the microcarps for the first time, the history of'cultivation by experience 'is ended, and industrialization and standardization of cultivation of the microcarps are promoted.

The present invention relates to the field of microbial control technology, and specifically to a strain of Streptomyces mycarofaciens DNW2 and an application thereof. The Streptomyces of the present invention is named Streptomyces mycarofaciens DNW2 and was deposited in the General Microbiology Center of the China Microorganism Culture Collection Administration Committee on September 2, 2022, with a deposit number of CGMCC No. 25639. The Streptomyces mycarofaciens DNW2 of the present invention is isolated from the rhizosphere soil of the virgin forest in Shunchang County, Nanping City, Fujian Province. It has strong growth adaptability, high acid-base tolerance, and can be harmoniously compatible with the soil ecology. The biocontrol agent prepared by the strain can effectively prevent and control various plant diseases such as honey pomelo black spot disease, honey pomelo anthracnose, honey pomelo black spot disease, pepper wilt, tomato wilt, banana wilt, banyan anthracnose, succulent black spot disease, tomato leaf mold, orchid stem base rot, corn stalk rot, strawberry root rot, etc., especially for honey pomelo black spot disease. The control effect is significant, and it has the advantages of being pollution-free and promoting growth.
