Hybrid rice tillering and large seedling transplanting machine single-planting and seedling-dividing method

Abstract

The invention discloses a method for single-seedling transplanting and seedling separating through a hybrid rice tillering big seedling transplanting machine. The method comprises the following steps: 1) shoveling the seedling, namely, draining water of a filed after the seedlings in a semi-dry rice seedling field or a dry raising field grow into tillering big seedlings and the seedlings are less than 30cm in height and 5.5-6.5 in leaf age, and then shoveling the seedling roots which are left 2-3cm on the ground through a root shoveling knife; 2) pulling up the seedlings, namely, manually pulling up the seedlings, and loading with mud on a seedling separating device, wherein the seedling separating device is used for distributing the seedlings by ranks and separating the seedlings of each rank; and 3) transplanting the seedlings, namely, removing the seedlings from the seedling separating device to the seedling transplanting machine after the mud at the seedling roots is dry and hardened, and then mechanically transplanting the seedlings. According to the method, the seedling separating device is adopted, so that the seedlings can be quickly loaded, and the seedlings can be conveniently distributed on the seedling transplanting machine, and as a result, the mechanical transplanting of the hybrid rice tillering big seedlings can be achieved, and the utilization efficiency of the hybrid rice tillering big seedlings is improved.

Description

technical field [0001] The invention relates to the field of hybrid rice tillering and large seedling single transplanting and seedling division, in particular to a hybrid rice tiller large seedling single transplanting and seedling dividing method. Background technique [0002] Since the invention of hybrid rice in the 1970s, single seedlings have been used to grow large seedlings with tillers and transplanted with tillers to promote high rice yields. At present, the existing rice transplanters in my country all adopt the multi-planting method of disc breeding and dense sowing of seedlings. This method uses a large amount of seeds, which leads to an increase in the cost of raising seedlings; the high seeding density of the seedling trays causes the seedlings to grow thin; transplanting small seedlings requires field drainage and transplanting, which is easy to cause weeds; Difficulty in raking; multiple transplants can easily lead to excessive field colonies in the later s...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the above-mentioned problems, the present invention proposes a method for single-planting and dividing seedlings of hybrid rice tillering seedlings, which solves the problems that the hybrid rice tillering seedlings cannot be machine-transplanted and the work efficiency of manual transplanting is low.
