Impacted-pneumatic hybrid rice seed production pollination machine and method thereof

Abstract

The invention discloses an impacted-pneumatic hybrid rice seed production pollination machine and a method thereof. The machine comprises a power chassis, a spike impact assembly and a blowing assembly, and the spike impact assembly and the blowing assembly are installed on the power chassis. The spike impact assembly is composed of a pull bar, a support, spike impact bars, a spike impact rack and the like, the pull bar is installed in the spike impact rack, the spike impact bars have a hinged joint with the pull bar and can slide in holes at two sides of the spike impact rack, and the spike impact angles of the spike impact bars can be adjusted by moving the pull bar; and the blowing nozzle of the blowing assembly is fixed below the spike impact assembly, and when pollens are slightly impacted by the spike impact bars and shed, the pollens transmit and diffuse with airflow blown by the blowing nozzle, and then settle to female parent stigmas to realize pollination. The machine which allows the impact to be adjusted through adjusting the angles of the spike impact bars and the pollens shredding after the slight impaction to be conveyed to the female parent through the airflow has the advantages of stable and uniform pollination, good pollination effect, small damages of the pollination process to plants, comfortable and convenient operation, high work efficiency, and suitableness for the large-scale hybrid rice seed production pollination.

Description

technical field [0001] The invention relates to a hybrid rice pollination machine, in particular to an impact-pneumatic hybrid rice seed pollination machine and a method thereof. Background technique [0002] Seed production is an important part of hybrid rice production, and pollination is the key to ensure the success of seed production. Sufficient and uniform pollination is an important guarantee to ensure seed setting rate, improve seed production quality and yield. However, at present, the mechanized water in the pollination process of hybrid rice seed production is extremely low, and it is basically done manually by farmers. The labor intensity is high, the operation efficiency is low, and it is difficult to complete in real time, which has a great impact on the yield and quality of seed production. At present, the auxiliary methods for hybrid rice seed production and pollination mainly include manpower and mechanical methods. (1) Manual pollination is a traditional p...

Problems solved by technology

(1) Manual pollination is a traditional pollination method, mainly including single long pole pollination method, double short pole pollination method and rope pollination method. ” requires fast action to ensure that the pollen bounces high and spreads wide, but the work efficiency is low and the labor intensity is high

The rope pollination method requires running and repeated rope pulling, uneven pollination, high labor intensity, and easy damage to the ear. The above artificial pollination method can no longer meet the development requirements of modern seed produ...
