Hybrid seed production efficient pollination machine

Abstract

The invention discloses a hybrid seed production efficient pollination machine, which can be used for pollination in crop seed production of hybrid rice, hybrid wheat, hybrid corn and the like. The pollination machine consists of a fan, a pollination wind pipe and a directional rope. The pollination machine utilizes the fan for blowing wind, and male patent pollen is uniformly spread onto a female parent ear chapiter at an angle being 45 to 70 degrees and at a speed being 2 to 3m / s for pollination. When the hybrid seed production efficient pollination machine is adopted, the pollination is uniform, the pollen utilization rate is high, the female parent setting percentage is high, 5 to 10 percent of speed production yield can be improved, the work efficiency is improved by 9 to 10 times, and the work intensity is greatly reduced.

Description

technical field [0001] The invention belongs to equipment for hybrid seed production of crops, in particular to a mechanical automatic pollinator for hybrid rice, wheat, corn and other crops. Background technique [0002] The popularization and application of hybrid rice, hybrid wheat and hybrid corn seeds is very important to ensure my country's grain production, increased yield, and stable yield, while the production and yield of hybrid seeds are mainly determined by seed production, including the population structure and affinity of male and female parents, Flowering meet or not, fertilization, pest control, hormone application, pollination and other factors. The seed production yield of a variety plays a key role in pollination quality and pollination quality, while factors such as fertilization and pest control are ultimately reflected in pollination quality and fruiting quality. Improving the pollination quality and seed setting rate of hybrid seed production is the ke...

Problems solved by technology

But the pollination of bamboo poles has many limitations, mainly 1. The pollination speed is slow and the labor intensity is high. It usually takes 50-65 minutes to achieve the effect of pollination per mu, twice in total.

2. The pollen is pushed by manpower and the force is uneven, and the speed of the push is weakened with the increase of the distance, so the flying distance of the pollen is limited

4. A large amount of pollen is scattered when the bamboo pole touches the male parent, resulting in insufficient and wasted pollen

5. Bamboo pole pollination is to shake the male ear to make the pollen rise. Due to the influence of strength and leaves, the pollen is hindered from entering the ear layer, which reduces the pollen efficiency and wastes a lot of pollen.
