A kind of uniform seeding device and using method based on dry rice seedling raising technology

Abstract

The invention discloses a uniform seeding device based on dry rice seedling raising technology and a method for using it. The device comprises a device body, the device body includes a uniform sowing device and a feeding device, the uniform seeding device includes a uniform trough inside, and the bottom of the uniform sowing device There are planting protrusions, and there are 4 equal-spaced screed conveying devices inside the planting protruding groove. The screeding conveyor includes a feeding pipe and a rotating turning roller, and both ends of the uniform seeding device are provided with soil turning structures. , the upper part of the screed tank is provided with a cover plate, and between the cover plate and the feeding device, there is a feeding pipeline 1 and a feeding pipeline 2. There is a steam heating device between the first and the second feeding pipeline, and the inside of the screed is provided with a filter residue vibrating screen plate. The beneficial effects of the present invention are: by setting the rotating turning roller and the screed trough, the germination efficiency is improved while ensuring the screed seeding efficiency.

Description

technical field [0001] The invention relates to the technical field of rice seeding, in particular to a uniform seeding device based on dry rice seedling raising technology and a using method. Background technique [0002] Rice (scientific name: Oryza sativa L.), commonly known as rice, is an annual aquatic herb of the Poaceae family. Stems erect, 0.5-1.5 m high, depending on the variety. Leaf sheath glabrous and loose; ligule lanceolate; leaf blade linear-lanceolate, about 1 cm wide, glabrous, rough. The panicle is large and sparse, with rough edges; the spikelet contains 1 mature flower; the glume is very small, leaving only a half-moon-shaped trace at the apex of the spikelet peduncle, and the cone-like spines; the lemma of the pregnant flowers is thick, with 5 veins , the midrib is ridged, the surface has small checkered papillae, thick papery, densely covered with fine hairs at the end hairs, with or without awns; palea and lemma are homogeneous, with 3 veins, apex po...

Problems solved by technology

[0003] At present, the existing rice uniform sowing device mainly controls the sowing efficiency of rice through the speed of walking and stirring, but the efficiency of the existing uniform sowing device is not high, and there is a problem of inefficiency for large-scale sowing. problem, and the existing device cannot control the germination rate of rice while sowing, so there is an urgent need for a uniform sowing device for rice dry seedling raising technology
