Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of crop breeding, and particularly relates to a pollen isolation device for anemophily flower pollinated crop. BACKGROUND

[0002] Anemophily refers to the process of using wind as a pollination medium, and plants pollinated under this mechanism are called anemophilous plants or anemophilous flowers. For example, plants such as Poaceae, Cyperaceae, Pinaceae, and Ginkgo are typical anemophilous plants. Spinach is also a typical anemophilous plant.

[0003] Taking spinach as an example, this anemophilous plant faces great challenges. First, although the wind-borne transmission of pollen is conducive to the increase of genetic diversity, it also makes the genetic stability of excellent traits complex and increases the risk of gene mixing. Second, anemophilous flowers need to adapt to specific environmental conditions such as wind speed, wind direction, and humidity, and changes in the environment have a direct impact on the success rate of pollination. These environmental factors must be considered during breeding. Third, anemophilous flowers also need to compete for pollination with other plants in the natural environment and face the pressure of natural selection to ensure that offspring can survive in the environment. During the breeding process, in order to maintain the purity, consistency, and stability of the variety, strict and effective isolation measures need to be implemented, such as isolating different varieties by at least 1 km in the breeding area and isolating the original breeding area by more than 2 km. In practice, methods such as steel pipe net rooms in greenhouses or regional isolation are often used for isolation, but these methods have some problems. For example, the construction and maintenance of steel pipe greenhouses are costly and require large-scale earthwork, which may have potential adverse effects on soil structure, leading to problems such as soil compaction, nutrient imbalance, and reduction of microbial communities. In addition, the cost of maintaining a steel pipe greenhouse is also high, and regular inspections and replacement of damaged parts, as well as cleaning of the sunshade net, all of which increase the cost of materials, labor, and time, and the greenhouse cannot achieve single plant isolation.

[0004] In summary, the previous isolation devices have the following problems: first, the isolation devices cannot achieve single plant or sister line isolation; second, traditional isolation devices are expensive, have insufficient light and air permeability, and can cause soil compaction during construction.
