Field auxiliary pollination machine for hybrid wheat

Abstract

The invention relates to a field auxiliary pollination machine for hybrid wheat. The field auxiliary pollination machine for hybrid wheat comprises a main plate frame, a partition board in the horizontal direction, side plates on two sides of the partition board and a rear elastic pollen plate on the rear side of the partition board, wherein an absorbing cavity is surrounded by the partition board, the two side plates and the rear elastic pollen plate. The field auxiliary pollination machine for hybrid wheat also comprises a plurality of pollen guiding mechanisms, wherein each pollen guiding mechanism comprises a wind pipe and an exhaust fan which is horizontally arranged in the wind pipe; each wind pipe is fixed to the upper part of the partition board, and lower pipe openings communicatewith the absorbing cavity; an electricity supplying power source is used for supplying electricity for exhaust fans; and hooks are fixed to the partition board, and can be horizontally hung onto a position in the front of a high-ground clearance powered vehicle. The field auxiliary pollination machine for hybrid wheat disclosed by the invention is mainly applied for performing auxiliary pollination in hybrid wheat seed farms; during working, the field auxiliary pollination machine for hybrid wheat advances along male parent ridges, the exhaust fans in the pollen guiding mechanisms start to work, and negative pressure is formed in the absorbing cavity; when a male parent wheatear is toggled by elastic pollen plates, pollen is ejected into the absorbing cavity, and upward suction force is applied; the pollen is blown to female parent fields on two sides of the pollination machine through the wind pipes, so that high-efficient pollination is completed, the field auxiliary pollination machine is especially suitable for the seed production combination that the male parent is obviously lower than that of the female parent, and the problem that in the prior art, pollination cannot be realized can be solved.

Description

technical field [0001] The invention relates to an agricultural mechanical equipment, in particular to a hybrid wheat field auxiliary pollinator capable of realizing field pollination by various hybrid combinations including parents with the same height or even a female parent obviously higher than the male parent. Background technique [0002] Utilization of heterosis is considered to be an important way to greatly improve wheat production in the future, and it is also a worldwide scientific and technological problem. Among the three major food crops in the world today, the application areas of corn and rice hybrids have reached 90% and 12% respectively, while wheat, which is the staple food of 75% of the world’s population and has an annual planting area of ​​more than 3 billion mu, has almost no hybrid applications. . It can be seen that hybrid wheat, which is brewing a huge contribution capacity, will become a new technological support for greatly improving the global f...

AI Technical Summary

Problems solved by technology

The artificial pulling rope method, the fan blowing method, and even the current popular helicopter pollen are all applied to the pollen from top to bottom or sideways. The pollen will fall downward due to gravity, and the wind is the same. Due to the effect of direction, it is difficult to increase the yield of seed production without pollination of the female parent. When the plant height of the parents is close to that of the male parent, or even the male parent is significantly higher than the female parent, there is no way to achieve large-scale seed production.

Wheat has a small glume opening angle and no nectar source to attract insects, so it is impossible to increase the pollination rate by measures such as releasing bees
