This application discloses a bumblebee feed for artificial breeding and its preparation method, relating to the field of feed technology. It addresses the problem of unclear dosage of potassium sorbate in bumblebee feed, leading to uncontrollable preservative effects or adverse effects on bumblebees. The feed consists of a feed base and potassium sorbate as a preservative, with a mass percentage of 0.08%–0.12%. The preparation method involves mixing potassium sorbate with the feed base to achieve a final mass percentage of 0.08%–0.12% in the feed.

This invention relates to the field of crop breeding technology, and in particular to a high-efficiency seed production method for greenhouse asparagus based on bumblebee pollination. Specifically, it includes: early and accurate identification of male and female plants using STS molecular markers during the seedling stage; scientifically matching male and female parents in a specific ratio and synchronously controlling their flowering periods; constructing a dedicated pollination net chamber with escape-proof buffer doors and microclimate fine-tuning design; implementing bumblebee-friendly green pest and disease prevention measures before flowering; and introducing bumblebees at a specific density for fully enclosed, high-efficiency pollination. This invention effectively overcomes the technical difficulties of high cost and low efficiency of traditional artificial pollination, as well as the problems of inconsistent flowering periods and heat stress on pollinating insects under conventional greenhouse conditions. Using the standardized breeding system of "molecular identification + spatial microenvironment + dedicated insect pollinator" constructed by this invention, the fresh fruit weight of a single plant can reach 300 grams, and the dry seed weight of a single plant can reach 56.2 grams. This not only eliminates interference from foreign pollen at the source, ensuring 100% purity, but also significantly increases the yield of hybrid seeds.

This utility model relates to a bumblebee breeding device, comprising a box, a first support member on one side of the box, a second support member on the other side of the box, a conveyor belt for removing excrement from the box, a scraping device for scraping excrement off the conveyor belt, a collection box for collecting excrement, and a cleaning device for cleaning the conveyor belt. The conveyor belt is mounted on the first and second supports; both the first and second supports are equipped with scraping devices; two sets of collection boxes are arranged opposite each other and correspond to the scraping devices; the cleaning device is located at the bottom of the conveyor belt, between the first and second supports. This invention solves the problem of many bumblebee breeding devices using fixed excrement plates, a design that is inconvenient for cleaning and disinfection. When removing excrement, bumblebees are sensitive to environmental changes; even slight vibrations can cause worker bees to become agitated and attack, posing a threat of stings to operators, which greatly complicates the excrement removal process.
