Problems solved by technology

[0002] Pingou hybrid hazel cultivation is a nut cultivation developed in the past 20 years. It has been cultivated in 1.2 million mu in 17 provinces and cities north of the Yangtze River, with an output of about 10,000 tons. In recent years, due to climate change, male inflorescences have fallen off, male flowers Frost damage, drying out of male inflorescences and other phenomena, resulting in insufficient male pollen in cultivated hazel gardens, which cannot fully pollinate female inflorescences, resulting in reduced yield;
[0003] In order to solve the above problems, it is necessary to manually collect male pollen, store male pollen, and artificially assist pollination. In the past, the method of storing male pollen had some shortcomings, such as inconvenient transportation, manual pollination, labor-intensive, low efficiency, and needs improvement

Embodiment 1

[0020] Embodiment 1 A kind of pollen collection and preservation method of Pingou hybrid hazel, comprising the following steps:

[0021] Step 1) male flower branch collection: collect male flower branches of multiple varieties of Pingou hybrid hazel in early spring, and the number of varieties of Pingou hybrid hazel is not less than three;

[0022] Step 2) male pollen collection: the male flower branches obtained in step 1 are cultivated by indoor hydroponics, and male pollen is collected on the elongated male inflorescence;

[0023] Step 3) Preservation of male pollen: the obtained male pollen is put into a bamboo tube, the bamboo tube used is breathable and has air inside, and the bamboo tube is selected with a capacity of 100g, sealed and placed in a refrigerator of 1°C, and refrigerated at low temperature.

Abstract

The invention discloses a pollen collection, preservation and artificial pollination method of Ping'ou hybrid hazelnut, the pollen collection and preservation method of Ping'ou hybrid hazelnut comprises three steps of male flowering branch collection, male pollen collection and male pollen preservation, and the artificial pollination method of Ping'ou hybrid hazelnut comprises three steps of male pollen viability inspection, preparation before pollination and pollination. According to the novel male pollen storage method, the storage capacity of the male pollen is improved, transportation is convenient, and the vitality of the male pollen is guaranteed; meanwhile, the provided pollination method can effectively improve the working efficiency and save the labor cost.

Description

technical field [0001] The invention relates to a method for artificial pollination of nuts, in particular to a method for collecting and preserving pollen and artificial pollination of Pingou hybrid hazelnut. Background technique [0002] Pingou hybrid hazelnut cultivation is a nut cultivation developed in the past 20 years. It has been cultivated in 17 provinces and cities north of the Yangtze River on 1.2 million mu, with an output of about 10,000 tons. In recent years, due to climate change, male inflorescences have fallen off and male flowers Frost damage to the inflorescence, draining of the male inflorescence, etc., lead to insufficient male pollen in the cultivated hazel orchard, unable to pollinate the female inflorescence completely, resulting in a decrease in yield; [0003] In order to solve the above problems, it is necessary to manually collect male pollen, store male pollen, and artificially assist pollination. In the past, the method of storing male pollen ha...
