Description
Technical Field
The utility model relates to a crossbreeding field, concretely relates to air-blowing type hybrid rice seed production pollination machine.
Background
The hybrid rice seed production is an important component of the hybrid rice production, and the pollination is also a key link of the hybrid rice seed production; the sufficient and uniform pollination is the premise guarantee for improving the seed production quality and yield; at present, the auxiliary pollination method for hybrid rice seed production mainly takes traditional manpower as main method. For hybrid rice seed setting, at least 3 pieces of pollen are required on each pistil style on average, so that the seed set can maintain the excellent characters of the male parent and the female parent, and can grow and develop into high-quality and high-yield hybrid rice seed.
The traditional natural pollination is to blow up the flower ears of the male parent directly by natural wind to pollinate the female parent area, the hybridization rate is generally between 0.2 and 4 percent and can reach as high as 5 percent, the maturing rate of the hybridization breeding is small, the yield is lowest and uncontrollable, and therefore, the requirement of the seed production and pollination of the hybrid rice can not be met only by depending on the natural pollination. At present, rice hybrid breeding is generally to manually beat plant panicle necks for pollination in a mode of manually vibrating the plant panicle necks (such as a single long pole pollen-driving method, a double short pole pollen-pushing method, a rope pollen-pulling method and the like) or by machine parts, wherein the manually assisted pollination has the characteristics of labor intensity, high labor intensity, low production efficiency and the like, and the two modes are to separate pollen of male parents from the panicles and fly the pollen to a female parent area for panicle pollination or directly blow the pollen of the male parents to the female parent area for pollination by natural wind. The traditional manpower type auxiliary pollination operation has the defects of high labor intensity, uneven pollination, too short flying distance of pollen, low production efficiency and the like, and is difficult to meet the requirement of modern seed production.
The mechanical assistance mainly replaces manpower with reliable tools, and mainly comprises pneumatic type, collision type and unmanned aerial vehicle wind power and the like. The principle of the pneumatic mechanical auxiliary pollination is that a fan is used for generating directional adjustable airflow to raise pollen of a male parent, and under the action of proper wind speed and a wind field, the pollen is spread to the female parent to finish pollination. The fan is used as a power source in Hedaming and the like, the pneumatic pollination machine is manufactured in a trial mode, the pollination of the hybrid rice is carried out, great progress is achieved compared with the traditional manual auxiliary pollination, the problems that the airflow speed is not accurately controlled, the pollen is greatly influenced by a flow field and the like still exist in the pneumatic auxiliary pollination, and a great promotion space is still provided for the pollination effect. The main principle of the collision type auxiliary pollination is to simulate the collision principle of a traditional manpower rod, rope and the like on the rice ears of the male parent, and the auxiliary pollination is realized by mechanical collision. In recent years, supplementary pollination of unmanned aerial vehicle wind-force obtains the application, and its principle is that the lower whirlwind that the rotor formed raises the pollen to along with the air current that the rotor formed, waft pollen to female parent and accomplish the pollination. The unmanned aerial vehicle is used for carrying out deep research on hybrid rice seed production supplementary pollination, and a good effect is obtained, but the unmanned aerial vehicle supplementary pollination has the problems of short endurance time, low efficiency, high technical requirement on operators and the like at present, and the large-area popularization and application still needs further optimization and improvement.
