Description
Technical Field
The invention belongs to the field of fruit tree production, and particularly relates to a pollen nutrient solution for improving pollination rate of pear trees.
Background
The pear is a self-pollination fruitless tree, and the corresponding yield and quality can be obtained only by matching and planting pollinated trees or artificial supplementary pollination in production. The pollination tree is planted in a matched mode, natural pollination is carried out mainly by utilizing the pollination capacity of insects, labor and force are saved, but pollination and fertilization are poor due to the influence of weather. In recent years, more and more pear gardens adopt artificial supplementary pollination. Although the manual pollination mode in the manual auxiliary pollination method has strong selectivity, high accuracy and small pollen consumption, the method has short operable time, more labor and higher production cost. In addition, the method of manually assisting solid powder spraying also has the problems of large using amount of the pollen and higher cost. The liquid pollination is a novel pollination technology, has the characteristics of high pollination speed and labor saving, can increase the water and nutrient of the stigma, and prolongs the pollination fertilization time of the stigma. However, in the prior art, the pollination rate of pollen is not high when the pollen nutrient solution for pear trees is used, and the pollen consumption is more in the proportioning process of the pollen nutrient solution, so that the pollen waste is caused, and the cost is increased. Therefore, a pollen nutrient solution for improving the pollination rate of pear trees needs to be researched so as to solve the technical problem.
