Problems solved by technology

However, this treatment method is to obtain pollen in an ultra-dehydrated state suitable for long-term storage. The pollen cannot be directly used for pollination, but needs to be rehydrated to restore activity.

Embodiment Construction

[0029] The present invention will be further described below in conjunction with specific examples.

[0030] (1) Experimental method

[0031] 1, pear orchard selection and bee colony admission: the present invention is research test material with pear. Select a pear orchard with a planting area of ​​more than 10,000 square meters, no competing flowers blooming around, and only pear trees as the pollen collection site. When about 20% of the pear blossoms are open, move the adjusted bee colony to the pear orchard, disperse the bee colony in the pear orchard, and install a depowdering device before depowdering.

[0032] 2. Pollen collection: collect artificial pollen and bee pollen for comparison.

[0033] The method of manually collecting pollen: pick buds at the budding stage, bring them back indoors, rub the flowers to separate the anthers from the filaments, sieve the anthers with a fine-mesh sieve with an aperture of 1.43mm, pick flowers after rain or when the petals are c...

Abstract

The invention relates to the technical field of collection of pollen for pollination, in particular to a method for obtaining pear pollen for pollination. In order to solve the technical problem, the invention provides a method which is stable in activity and simple to operate, and used for obtaining pollen for pollination. The method is characterized by comprising the following steps: selecting a pear orchard where a single type of pear trees are planted; dispersively releasing a swarm of bees into the pear orchard for free gathering when 20% or more of the pear trees in the pear orchard bloom; collecting pollen loads gathered by the bees once every 8-15 minutes between 9-11 a.m. everyday; performing vacuum freeze drying treatment on the collected pollen loads, so as to obtain the pear pollen for pollination. The process of vacuum freeze drying treatment comprises the following steps: performing pre-freezing treatment on the pollen loads for 2 hours; performing vacuum freeze drying treatment on the pre-frozen pollen loads for 10-13 hours; crushing the dried pollen loads. The obtained pear pollen is more uniform and higher in quality, and a set of technologies for obtaining the high-purity and high-activity pear pollen for pollination are formed.

Description

technical field [0001] The invention relates to the technical field of collecting pollen for pollination, in particular to a method for obtaining pear pollen for pollination. Background technique [0002] Pear trees belong to Rosaceae and Pyrus in taxonomy. They are perennial woody plants and are widely planted in my country. The vast majority of pear varieties are self-incompatible, self-pollination does not bear fruit or the fruit-setting rate is extremely low, and pollination trees or artificial pollination must be arranged in production to obtain a good harvest. However, with the continuous advancement of my country's agricultural modernization process and the large-scale planting of single-species crops, the number of pollinators in farmland has dropped significantly, and pear tree production has gradually increased its dependence on artificial pollination. To artificially pollinate pear trees, it is first necessary to have sufficient and highly active pear pollen. In...
