The decrease of honeybees in our country rings the ecological alarm

Introduction: without bee pollination, the crops in the greenhouse will have low seed setting rate The number of honeybees in China has decreased from 7.5 million in the early 1990s to 6.8 million at present Experts call for the role of bees in improving ecology and preventing pollution Recently, at the National Symposium on environmental quality construction of agricultural products producing areas, agricultural resources guarantee and environmental protection, experts attending the conference pointed out that bees play a major role in pollination in the biosphere, especially that artificial beekeeping can control the pollination of bees At present, most of the more than 1000 crops used by human beings need bee pollination "A worker bee can attach more than 20000 pollen grains, far more than other insects When it flies from one flower to another to collect pollen, it completes pollination, which has an important ecological function to maintain the stability of agricultural biodiversity." Wang Yong, Secretary of the Party committee of the Bee Research Institute of the Chinese Academy of Agricultural Sciences, said Wang Yong said that because there are almost no pollinators such as bees in greenhouses and greenhouses, crops have low seed setting rate, low yield and poor quality Although fruit farmers take measures such as applying hormones to crops to protect flowers and fruits, there are many malformed fruits and fruits with poor taste, which will also cause chemical hormone pollution Scientific experiments have proved that honeybee pollination can increase the fruit size and reduce the rate of malformed fruit.
