Rice dry-culturing seedling disc as well as seedling raising method and application thereof

Abstract

The invention relates to a rice dry-planting seedling disc as well as a seedling raising method and application thereof, belonging to the technical field of agricultural machinery equipment. The rice dry-planting seedling disc comprises a disc body, bowl bodies and support bodies, wherein the bowl bodies are inverse cone bodies and are located in the disc body; at least three grooves are formed in the disc body, and the support bodies are located in the grooves; the support bodies are used for supporting the seedling disc so as to conveniently place seedlings on a rice dry-planting machine in piles. By raising the seedlings by virtue of the seedling disc, soil at the roots of the raised seedlings is moderate in dryness and humidity, is dry and comfortable, is agglomerated and is not easily scattered during mechanical dry planting, so that the operations of seedling separation, seedling transportation and mechanical dry planting are easily realized. The seedling disc is applied to the specific rice dry-planting machine and is excellent in energy conservation; compared with a traditional rice transplanter which is high in mechanical energy consumption while walking in an irrigated land, the rice dry-planting machine which is used for planting the seedlings on a dry farmland has the advantages that the more energy is saved, and the speed is relatively high; the operation time can be conveniently controlled, and the seedling transplanting time can be shortened; compared with a seedling throwing manner, a mechanical seedling transplanting manner and a manual seedling transplanting manner, the seedling transplanting time can be shortened.

Description

technical field [0001] The invention relates to a paddy seedling-planting tray and a seedling-raising method and application thereof, belonging to the technical field of agricultural machinery and equipment. Background technique [0002] Rice is the main food crop in my country, and its planting area and output both rank second. my country has a long history of planting rice. Rice was planted in the Xia Yu era more than 4,000 years ago. The rice planting method in my country generally adopts paddy field transplanting. The main transplanting methods include manual transplanting, manual throwing, mechanical transplanting and mechanical throwing. The existing water-field transplanter is transplanting, and the seedlings are prone to floating when inserted into the water. Transplanting rice seedlings by manipulators will cause greater damage to the seedlings, the position of transplanting rice seedlings is likely to be irregular, and the survival rate of rice seedlings is low.

AI Technical Summary

Problems solved by technology

Each of these planting methods has its advantages and disadvantages: manual transplanting is labor-intensive, and manual throwing, mechanical transplanting and mechanical throwing can all reduce labor intensity, but the requirements for paddy field preparation are relatively high, and the land must be as flat as possible.

The disc body of this document is arranged at intervals of vertical and horizontal grid strips to form independent seedling raising boxes, which are not integrated with the seedling raising film. In the process of rice seedling raising with this structure, the root system is easy to pass between the spacer frame and the lifting film. The seedling film passes through, the root system is coiled together, the seedling block is not easy to separate, which affects the mechanical seedling planting, and the structure of the transplanter provided in this document and the pre-processing of the seedlings are relatively complicated, and the seedlings are easy to block the passage in the seedling tray, resulting in failure. The rate is high. If a fault occurs during the operation, it is difficult to control and remedy it in time, and the specifications of the seedling tray are limited, which is not conducive to large-scale and long-term field operation.

The machinery traditionally used for planting tobacco requires manual feeding and is not suitable for dry planting of rice

[0004] Most of the existing rice seedling trays for mechanical transplanting are full-plate structures, which are suitable for hydroponics in paddy fields. plant
