Male parent special rice transplanting machine for use in hybrid rice seed production and method of machine

Abstract

The invention discloses a male parent special rice transplanting machine for use in hybrid rice seed production and a method of the machine. The male parent special rice transplanting machine comprises a handrail rack, an engine, a walking chassis, a planting gearbox, front planetary gear type transplanting mechanisms, rear planetary gear type 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 planetary gear type transplanting mechanisms are arranged on both sides of the planting gearbox; two rear planetary gear type 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. By adopting the male parent special rice transplanting machine, spaced transplanting of hybrid rice male parent seedlings of different ages on the same ridge is realized, and distribution of large and small seedlings on two lines of male parent ridges in a triangular shape is realized.

Description

technical field [0001] The invention relates to a rice transplanter, in particular to a special rice transplanter for male parent of hybrid rice seed production 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 se...

Problems solved by technology

[0003] The purpose of the present invention is to provide a special rice transplanter for hybrid rice seed production 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.
