Description

Technical Field

[0001] This utility model relates to the field of fruit tree hybridization breeding technology, and in particular to an artificial pollination device for fruit tree hybridization breeding. Background Technology

[0002] Fruit tree hybridization breeding, through gene recombination between different varieties, integrates superior traits into offspring, making it a key approach to cultivating high-quality, high-yield, and disease- and pest-resistant new varieties. Hybridization allows apples to possess both high sweetness and cold resistance, and citrus fruits to gain stronger disease resistance. Under natural conditions, fruit tree pollination is significantly affected by insect activity, wind, and weather factors, and differences in flowering time and pollen viability among different varieties make it difficult to precisely control hybrid combinations, resulting in low breeding efficiency and unstable target traits. Artificial pollination, on the other hand, allows for targeted selection of the male and female parents, ensuring the purposefulness and controllability of hybridization.

[0003] In the field of fruit tree hybridization breeding, artificial pollination is an important means of cultivating superior varieties. It plays a key role in improving fruit quality, yield, and enhancing the resistance of fruit trees to adverse conditions. Traditional artificial pollination methods mainly rely on manual brushing to collect pollen and then applying it to the stigma of the pistil. This method is cumbersome and inefficient. It is also difficult to accurately control the force and application area of ​​the manual operation, which can easily lead to uneven pollination and low fruit set rate. This method is difficult to meet the needs of large-scale hybridization breeding. Artificial pollination requires training to control the amount of pollen and the application location based on experience. After long-term work, due to staff fatigue, it is difficult to carry out standardized pollination training, resulting in insufficient pollination, affecting fruit set rate and seed quality. In addition, the operation is difficult and it is difficult to cover all target flowers. Utility Model Content
