Hand-held hybrid rice seed production male parent transplanter and method thereof

Abstract

The invention discloses a walking type male parent rice transplanting machine for use in hybrid rice seed production and a method of the machine. The walking type male parent rice transplanting machine comprises an engine, a walking chassis, a handrail rack, a planting gearbox, front crank rocker transplanting mechanisms, rear crank rocker transplanting mechanisms, a transmission case, a front seedling transplanting and feeding mechanism and a rear seedling transplanting and feeding mechanism, wherein the engine is arranged at the front part of the walking chassis; the planting gearbox is arranged at the rear part of the walking chassis; the handrail rack is fixed to the lower back side of the planting gearbox; the front seedling transplanting and feeding mechanism, the transmission case and the rear seedling transplanting and feeding mechanism are fixed in sequence to the handrail rack in the longitudinal direction; two front crank rocker transplanting mechanisms are arranged on both sides of the planting gearbox; two rear crank rocker transplanting mechanisms are arranged on both sides of the transmission case; the planting gearbox is used for transmitting power to the transmission case through chain transmission. During rice transplanting, large and small rice seedlings of different ages are placed onto a front seedling transplanting stage and a rear seedling transplanting stage respectively. After transplanting, triangular distribution of the large rice seedlings and the small rice seedlings on two lines of hybrid rice male parent ridges is realized.

Description

technical field [0001] The invention relates to a rice transplanter, in particular to a hand-held hybrid rice seed production male parent transplanter and a method thereof. Background technique [0002] In order to ensure that the male parent and the female parent meet at the flowering stage in the hybrid rice seed production process to improve the quality and yield of the hybrid seed production, the male parent needs to provide a longer pollen period so that the female parent at different flowering stages can be pollinated. In order to achieve this goal, it is generally required to plant seedlings of two male parents with a certain age difference in two phases and in two batches. Two times the spacing between the plants is planted at intervals, so that the large seedlings of the two rows of male parents are distributed in a "pin" or triangle, and the small seedlings of the male parents are inserted between the large seedlings every other day, that is, the small seedlings of...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a walk-behind male hybrid rice transplanter and its method in order to overcome the shortcomings of the existing rice transplanter that cannot meet the specific agronomy of hybrid rice seed production male parent transplanting, manual transplanting is difficult to complete in a timely manner, etc.
