This invention provides a method for enhancing the efficacy of *Citrus trifoliata* (bitter orange) cultivation and suppressing weeds, belonging to the field of ecological planting technology. This method is suitable for mature fruiting *Citrus trifoliata* forests, achieving both fertilization and weed suppression. It efficiently combines woody medicinal herbs, legumes, and herbaceous medicinal herbs, rationally intercropping them according to their growth and development cycles to fully utilize the plant growth cycles and achieve the goals of efficient land use, soil improvement, and diversified income synergy. This is of great significance for promoting the standardized and ecological cultivation of Chinese medicinal herbs. Using this method, the annual application of chemical nitrogen fertilizer can be reduced, increasing soil organic matter content; a year-round continuous weed suppression system is constructed, with wild peas covering in winter and cassia seed covering in summer, improving weed control efficiency and reducing manual weeding costs; significantly increasing the fruit setting rate, single fruit weight, and effective fruit components of *Citrus trifoliata*; and increasing economic benefits in the forest.

The invention discloses a special fertilizer for promoting blossom, protecting fruits, increasing yield and improving quality of anise and a preparation method thereof, and belongs to the field of organic fertilizers. The formula comprises the following components in parts by mass: 500 parts of compound fertilizer, 20 parts of borax, 200 parts of medium trace element fertilizer, 40 parts of peanut bran, 360 parts of dried pig manure, 40 parts of fishbone dust, 230 parts of mushroom residues and 4 parts of microbial flora. The microorganism bacterium is a bacillus stearothermophilus fermentation bacterium agent; the nutrient content of the biological organic fertilizer is not less than 15%, and the organic matter content is not less than 40%. The borax and the medium trace elements in the formula have a synergistic effect and are matched with the microbial flora to promote nutrient absorption, so that anise bud cultivation can be effectively promoted, the flowering amount and the fruit setting rate are increased, leaves and growing branches of anise after fertilization are increased, the leaf color is dark green, and flower and fruit falling phenomena are obviously reduced. The high organic matter content can improve the soil hardening condition and improve the soil breathability and the water and fertilizer retention capacity, the microbial flora adjusts the soil micro-ecology, the soil fertility can be continuously improved after long-term application, and healthy growth of anise trees is promoted.

The invention provides a compound sodium nitrophenolate-thidiazuron microemulsion and a preparation method thereof. The microemulsion comprises an effective component, a high-molecular long-chain EO-PO polymer and an auxiliary material part, wherein the high-molecular long-chain EO-PO polymer comprises a polymer with the molar molecular weight of 5000-30000. According to the invention, a high-molecular polymer is creatively used for coating a thidiazuron active compound in a nanoscale micro-droplet state, so that the problem that thidiazuron is greatly decomposed after the thidiazuron active compound and compound sodium nitrophenolate are compounded to prepare the microemulsion is solved; meanwhile, the high-molecular polymer disclosed by the invention replaces a traditional solvent dissolution form with a form of wrapping a thidiazuron active compound, so that a slow-release effect is achieved, the long-acting property of the whole preparation is improved, the medication frequency and the dosage are less, meanwhile, the high-molecular polymer is safe to crops, the plant vigor is improved, the fruit setting rate can be remarkably increased, and the stress resistance of plants is enhanced.

The application provides an ultrasonic and airflow coordinated pollination device and method, and relates to the technical field of agricultural production. The device comprises an image acquisition module, a control module and a plurality of pollination execution units. The image acquisition module is used to acquire position information of a flower to be pollinated. The control module is used to control the mechanical arm of each pollination execution unit to move and align with the flower to be pollinated based on the position information. After the alignment of each pollination execution unit, the ultrasonic vibration module of each pollination execution unit is controlled to vibrate towards the flower to be pollinated, and the airflow generation module of each pollination execution unit is controlled to generate directional airflow towards the flower to be pollinated. The high-frequency vibration generated by the ultrasonic vibration module can simulate the buzzing pollination behavior, so that a large amount of active pollen is shaken off. The directional airflow generated by the airflow generation module blows the shaken-off pollen to adhere to the stigma of the flower. Based on the coordinated design of vibration and airflow, the success rate of single pollination and the utilization rate of pollen are improved, and the pollination quality is ensured.

The application provides a method for promoting pollination and fruit setting of amomum villosum by artificial assistance, and relates to the technical field of amomum villosum planting. The method is characterized by using beta-pinene, benzaldehyde, p-methoxycinnamaldehyde and anhydrous ethanol as chemical attractants to treat amomum villosum plants in the flowering stage, and then using gibberellin, naphthalene acetic acid, flue-cured tobacco straw fermentation extract, ethylhexylglycerin, anhydrous ethanol and borax as fruit setting agents to spray the amomum villosum plants after the chemical attractants are sprayed. The method overcomes the shortcomings of the prior art, effectively improves the fruit setting rate of amomum villosum, reduces the artificial loss, and comprehensively improves the economic benefits of planting.

The application discloses a configuration method for pollination trees in Gleditsia sinensis plantations and belongs to the technical field of Gleditsia sinensis planting. In the configuration method, the planting quantity ratio of Gleditsia sinensis female plants, Gleditsia sinensis var. cathayensis male plants and Gleditsia delavayi male plants is set to 26-30:1-3:1-2, and the planting quantity of the Gleditsia sinensis var. cathayensis male plants is greater than that of the Gleditsia delavayi male plants. By introducing the Gleditsia sinensis var. cathayensis with early flowering period and the Gleditsia delavayi with late flowering period to perform interspecific cross-pollination, the application realizes the continuation and coverage of the flowering period, guarantees the continuous supply of male pollen in the whole female flower opening period, greatly improves the fruit setting rate and yield of the Gleditsia sinensis, and significantly improves the pod and seed quality of the Gleditsia sinensis var. cathayensis and the Gleditsia delavayi, including the significant improvement of saponins, amino acids, pectin and total sugar components. It can be seen that the application significantly improves the production efficiency of the Gleditsia sinensis plantations.
