传粉昆虫访花习性和为韭菜授粉作用

Visiting characteristics of insect pollinators and its pollination function for Chinese chives

本文对韭菜田传粉昆虫访花习性和韭菜授粉作用进行了研究。结果表明,意大利蜜蜂是白天访问韭菜花的优势昆虫,每次访花时间为57.13 s,每次访问韭菜花序1.11个,是韭菜田白天最主要的授粉昆虫,意大利蜜蜂授粉使韭菜花结籽率提高18.16%,显著提高了韭菜种子产量。同时,其他昆虫对韭菜花传粉作用为64.63%,对于维持韭菜繁殖有重要作用。

Behavior and pollination function of insect pollinators to Chinese chives （Allium Tuberosum） were stud- ied. The results showed that Apis mellifera ligustica Spinola was the most dominant insect of visiting Chinese chive flowers and the most important pollinator in the daytime. Its visiting time lasted 57.13s in one visitation, and visited 1.11 flowers per time. Pollination of A. mellifera ligustica promoted 18.16% Chinese chive seed setting rate. Other in- sects also contributed 64.63% pollination, which was important to maintain the Chinese chive production.
