A high-efficiency precision positioning seeding method

Abstract

The invention relates to a high-efficiency accurate-measurement positioning seeding device and a method for seeding employing the same. The seeding device is composed of two structures A and B. The structure A can be placed in the structure B, and can move in the structure B. The middle part of the structure A is a seeding region. Seed holding tanks are arranged at two ends of the seeding region. One end of the structure A extends outwards and forms a handle. The cross section of the seeding region of the structure A is wave-shaped. A plurality of seeding holes are arranged at the wave-shaped valley bottoms. When a plate A is placed in the structure B, Seed passing holes are arranged in positions, corresponding to the seeding holes of the structure A, of the structure B. the seed passing holes correspond with the seeding holes one by one, and deviate towards one side by about half hole pitch relative to the seeding holes. The sizes of the seed passing holes are larger than that of the seeding holes. The provided seeding device is employed for seeding, high-efficiency accurate-measurement positioning can be achieved, the seeding quality and efficiency are raised, the seeding cost is lowered, convenience is provided for seedling growing production, and the provided seeding device is suitable for large-scale popularization.

Description

technical field [0001] The invention relates to a sowing method, in particular to a high-efficiency and precise positioning sowing method, which belongs to the field of agricultural technology. Background technique [0002] Sowing is an important part of raising seedlings. On the one hand, precision positioning sowing can strictly control the seeding rate, and on the other hand, it can strictly control the distribution position of seeds, so as to realize the reasonable use of seedlings' growth space and soil nutrients, and improve the quality of seedlings. [0003] Most crop seedlings (such as rice, rapeseed, vegetables, flowers, etc.) are required to cultivate relatively high-density seedlings in a small space (such as seedling trays) (such as the sowing density of rapeseed blanket seedlings is required to reach 4000-6000 plants / m 2 ), to meet the requirements of transplanting machinery and improve transplanting efficiency as much as possible. The control of seeding ra...

Problems solved by technology

But there are still some places to be improved in the sowing device made by this method, which are mainly reflected in: 1. During the process of sieving the sowing device to make the seeds fall into the sowing holes, the rolling direction is random because the seeds roll on the A plate plane The probability of falling into the seeding hole is relatively small. Even after repeated sieving, the rate of empty seeds in the seeding hole is relatively high.

2. The excess seeds are stored on the surface of the A plate, which can easily enter the sowing hole during the sowing process, resulting in the phenomenon of multiple seeds in one hole, which affects the sowing effect

3. Due to the inconvenience of storing more seeds on the surface of A board, the frequency of seed replenishment is high, and continuous sowing cannot be realized, which affects the sowing efficiency
