Problems solved by technology

[0002] In current hybrid rice seed production, the pollination work is done manually. The most basic and widely used method is human pollination with bamboo poles. A single person uses bamboo poles to drive pollination, and one person can pollinate 3-3.5 mu of field; two people use ropes to pull flowers for pollination. Two people can pollinate 10-15 mu each time; due to lack of labor and high labor costs, it has seriously affected the price of hybrid rice seeds and the implementation of hybrid rice production bases.
Some seed production areas use manpower or machinery (electric vehicles, tractors) to pull ropes for pollination, but due to the influence of field roads and field obstacles, the use is restricted

Embodiment Construction

[0008] In order to make the object, technical solution and advantages of the present invention clearer, the following examples are given to further describe the present invention in detail.

[0009] When UAVs are used in hybrid rice seed production and pollination, when the flying speed is higher than 4 meters per second, the flying state is unstable and it is easy to cause the plants to fall; when the flying speed is higher than 6 meters per second, the UAV is easily affected by natural wind , the chance of falling increases, and there are unsafe factors; when the flying speed is 4 meters per second, the flying state is the most stable, and the wind generated by flying has the most favorable impact on rice pollination, and will not cause the plants to fall; the flying speed is lower than per second. At 4 meters per second, the flight cost increases;

[0010] When UAVs are used in hybrid rice seed production and pollination, when the flying height is 1.5 meters, the wind force...

Abstract

The invention discloses a hybrid-rice seed production and pollination method by unmanned aerial vehicles. The flying distance of the unmanned aerial vehicles with plants is 2-3 meters, the flying speed is 4-6 meters per second, and the flight spacing is 1.5-3.5 meters. The method has the advantage that the problems of shortage of labor force in hybrid-rice seed production, high scale and cost in large-scale production, and the like are solved, and the method can be widely applied to production.

Description

technical field [0001] The invention relates to the technical field of hybrid rice seed production and pollination, in particular to an unmanned aerial vehicle hybrid rice seed production and pollination method. Background technique [0002] In current hybrid rice seed production, the pollination work is done manually. The most basic and widely used method is human pollination with bamboo poles. A single person uses bamboo poles to drive pollination, and one person can pollinate 3-3.5 mu of field; two people use ropes to pull flowers for pollination. The two can pollinate 10-15 mu each time; due to lack of labor and high labor costs, the price of hybrid rice seeds has been seriously affected, and the implementation of hybrid rice production bases has been seriously affected. Some seed production areas use manpower or machinery (electric vehicles, tractors) to pull ropes for pollination, but due to the influence of field roads and field obstacles, the use is limited.
