This invention provides a method for controlling Spartina alterniflora and promoting natural mangrove restoration based on rolling mulching and in-situ mud slurry, belonging to the field of ecological control technology. The method involves mechanically rolling Spartina alterniflora to flatten most of it and press it into the tidal flat soil. Then, a biodegradable mulch film is laid on top, and mud slurry is extracted and applied to form a mud slurry cover layer. A mangrove seed interception and planting device is then installed on the mud slurry cover layer to prevent mangrove seeds from growing naturally, thereby reducing the cost of Spartina alterniflora control and improving the efficiency of Spartina alterniflora control.

The utility model discloses a prefabricated ecological crown beam which comprises a front vertical plate, a rear vertical plate is arranged on the rear side of the front vertical plate, and the front vertical plate and the rear vertical plate are arranged in a front-back mirror image mode. A cross beam is arranged between the front vertical plate and the rear vertical plate, and the front vertical plate, the rear vertical plate and the cross beam are connected through connecting bolts; the integral structure of the crown beam is split into single components of the plate and the beam, so that a mold structure is very simple during production, and the manufacturing cost of the mold is very low; the crown beam can be split into single components, so that the crown beam can be split in the production process, and after the crown beam is split into the single components for production, the operation process becomes simpler, and the production efficiency becomes higher; in addition, the storage space of the single assemblies is reduced, the storage capacity of the same area is increased, and the site occupation cost is reduced.

The invention discloses a method for promoting growth of intercropping crops based on a soil micro food web and application of the method, and belongs to the technical field of crop planting. According to the invention, it is found for the first time that by adding a specific type of bacterial-feeding nematodes into soil, synergistic improvement of growth indexes such as plant height, stem diameter and biomass of two crops can be obviously and stably promoted; the application method is simple and easy to operate, the cost is controllable, and no additional farming equipment or steps are needed; the method is high in environmental compatibility, is particularly suitable for a farmland peanut-corn intercropping system in alkaline and calcareous soil, can effectively improve the crop growth performance, farmland productivity and agricultural product yield and quality, can optimize the soil ecological function, continuously increases the economic benefits of farmers, and has wide application prospects. A brand-new, low-cost and easy-to-popularize candidate scheme is provided for agricultural green sustainable development of the alkaline soil area in North China, and the application prospect is wide.

The application provides a kind of water level fluctuation river beach zone degraded wetland Juncus effusus community directional recovery method, belongs to wetland water environment ecological management and landscape restoration technical field.The application includes the following steps: (1) the hydrological condition of river beach zone degraded wetland is investigated, and the target recovery area and the transplanting height and time of Juncus effusus are determined: the transplanting height of low-lying area is greater than or equal to 30 cm, and the transplanting is carried out in early May; the transplanting height of water level change area is greater than or equal to 25 cm, and the transplanting is carried out in early May; the transplanting height of humid area is greater than or equal to 20 cm, and the transplanting is carried out in mid-late May; (2) the degradation degree of Juncus effusus in the target recovery area is investigated, and the transplanting density of Juncus effusus is determined: the natural recovery is carried out in slight degradation area, 20-30 plants / m 2 are transplanted in moderate degradation area, and 40-60 plants / m 2 are transplanted in severe degradation area.The application can not only improve the growth adaptability of Juncus effusus, but also enhance the ecological function of wetland, and provide a new solution for ecological protection and sustainable development.

The invention relates to the technical field of green prevention and control of agricultural pests, in particular to a green prevention and control method for rice pests based on combination of multiple spiders and application of the green prevention and control method for rice pests based on combination of multiple spiders. Placing density and position of the spiders: after the rice is transplanted, uniformly putting the combination of the various spiders into the rice field according to the putting density; and ecological environment optimization: arranging shelters for inhabiting and avoiding of the spiders in the rice field to promote survival and reproduction of the spiders. According to the method, multiple spiders with ecological niche complementarity are screened, a natural enemy community which can be stably colonized in a rice field and has a synergistic effect is constructed, continuous and efficient control over main pests of rice is achieved, and finally the purposes of completely replacing chemical pesticides, protecting the ecological environment and producing green rice are achieved.

The application belongs to the field of soil improvement, and relates to a method for applying a modifier for soil acidification in southern forests, by which goethite as a mineral modifier can effectively increase soil pH, adjust soil acidity, improve soil carbon sink capacity, comprehensively improve the plant habitat, and further promote plant growth, so as to simultaneously realize soil habitat improvement and ecological function improvement of the southern forests.

The utility model discloses a curb structure based on a sponge city concept. The curb structure comprises a plurality of curb bodies arranged side by side and a plurality of pervious concrete bases arranged on the lower surfaces and the back sides of the curb bodies side by side. The utility model has the following advantages and effects: when rainwater near the curb body permeates, part of rainwater can permeate downwards to the pervious concrete base, so that rainwater infiltration is accelerated, surface runoff scouring is reduced, urban inland inundation risk is reduced, and a'permeation 'square needle of a sponge city concept is realized; part of rainwater flows along the drainage holes and the first connectors of the concrete base and is drained to an inspection well from the second connectors used for being connected and achieving drainage, and the'row '-shaped square needle of the sponge city concept is achieved. Finally, rainwater management is optimized through a sponge city concept, the ecological function is enhanced, the sustainability of infrastructures is improved, and multiple benefits are achieved.
