Seed rain refers to the scale number of seed propagules from a parent plant to different sites through different media after the seed propagules are separated from the parent plant, and is generally specifically characterized by a seed rain unit density index. As an indispensable important part of plant life history, monitoring dynamic change of seed rain can effectively simulate plant setting season law, forecast community space distribution pattern, and play an important role in improving structural stability and perfect functions of components, promoting local ecological system update and the like. The grass hills are vegetation landscapes widely distributed in natural wetlands in northern China, and play an important role in conserving water sources, purifying water quality, regulating runoffs, biologically fixing carbon, providing habitats and maintaining biological diversity. In recent years, the problem of degradation of the grass hills and the wetlands is serious due to the comprehensive influence of climate change and human activities, and the implementation of the repair of the grass hills and the wetlands is urgent. The grass seeds are used as sexual propagation carriers, can be propagated through different mediators after natural scattering is finished, and have important roles in realizing population update continuation, restoring degenerated habitat and the like. The implementation of the scientific research work of the seed rain of the grass hills can provide a data basis for exploring the formation mechanism process of the grass hills, and enrich innovative ideas for the repair technology of the formed grass hills. At present, seed rain investigation mainly adopts several measuring devices such as a buried collecting barrel, a ground-leaving collector or an assembled collecting net, and investigation objects are grasslands, woodlands or short shrubs. The buried collecting barrel is buried to the ground surface, so that the ground imitation effect is good, the operation and implementation are convenient, the buried collecting barrel can adapt to various investigation environments, but local vegetation is damaged in the laying process, the midway seed collection work is complex, and the buried collecting barrel does not have the capability of draining accumulated water; the ground-off collector has stable structure and excellent seed preservation performance, but the device has complex structure and high construction cost, and is not suitable for large-scale application in outdoor environments; the assembled collecting net device is light and portable, but is only suitable for experimental scenes such as forests or short shrubs, and cannot be arranged in a wetland environment. Therefore, how to design a seed rain collecting device which is safe, environment-friendly, portable, easy to apply, low in cost and suitable for a wetland environment, and a scientific layout and operation method matched with the seed rain collecting device are important problems to be solved in the field of wetland scientific research.
