Mechanization and labor-saving of mulch cultivation planting

Abstract

The planting machine has been improved so that it can step over mulch, and a unique hopper has been attached to allow planting without breaking the mulch. [Effect] It can contribute to labor saving and improving the quality of green onions.

Description

[Technical Field]

[0001] The present invention relates to a cultivation method that realizes labor saving by mechanizing the planting work of mulched cultivation of leeks and contributes to quality improvement. [Background technology]

[0002] Modern mulch cultivation of long onions is all planted by hand, with each onion seedling planted in a hole in the mulch, planted in December and shipped in May. In response to recent abnormal weather and rising material costs, there is a demand for greater labor savings, and mulch cultivation is attracting attention as a way to ensure stable yields, but the heavy burden of planting work is a challenge for onion producers.

[0003] Furthermore, during the growing period of traditional leek cultivation, weeds grow intermittently between the plants and between the rows, which often requires constant weeding. This requires weeding in the high temperatures of summer and the spraying of herbicides, and is the most time-consuming and cost-intensive part of the leek cultivation stage, making it a major obstacle to stable leek cultivation.

[0004] Due to recent abnormal weather, the summer of 2023 was a year of extreme heat and dryness, resulting in a poor harvest, and it is known that the summer of 2024 was affected by extreme heat and heavy rain, resulting in a second consecutive year of poor harvest.However, since adequate moisture is important for growing long onions in the summer, the issue of not being able to protect the roots in the soil while ensuring water retention has been highlighted.

[0005] None of the transplanter manufacturers currently selling machines can span the width of mulch rows, and when planting on top of the mulch, the mulch breaks and planting becomes impossible, so the above-mentioned issues have not been resolved.

[0006] The present invention has been made to solve the problems of conventional cultivation techniques as described above, and aims to provide a mulch cultivation method that mechanizes planting work to improve the quality of leeks. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Patent Publication No. 6-269206 Summary of the Invention [Problem to be solved by the invention]

[0008] The problem to be solved is that, despite the effectiveness of mulch cultivation methods, manual planting work has been a barrier. However, mechanization contributes to reducing the labor required for planting work, improves the efficiency and labor required for weeding work that occurs during the summer growth stage, and ensures a sufficient amount of moisture to cope with abnormal weather such as extreme heat.The present invention, configured in this way, can improve the quality of leeks. [Means for solving the problem]

[0009] In order to achieve the above object, the present invention has the following configuration.

[0010] When planting in December, green, holeless mulch is used to enhance heat retention, and during other growing periods, black and white mulch is used to lower the ground temperature, but in both cases, 135cm wide holeless mulch is used.

[0011] The planting machine has been modified by extending the axles of a semi-automatic onion flatbed transplanter, allowing it to straddle 135cm wide mulch.Furthermore, the existing side-opening hopper has been removed and a smaller, thinner hopper has been installed to prevent the mulch from tearing when transplanted, thereby achieving mechanization of planting. [Effects of the Invention]

[0012] According to the present invention, it is possible to provide a cultivation method that realizes labor saving and quality improvement during planting in green onion cultivation. [Brief explanation of the drawings]

[0013] [Figure 1] Figure 1 is an explanatory diagram showing the method of planting (Example 1).

Claims

[Claim 1] The mechanization of planting is realized by extending the axle of a semi-automatic leek flatbed transplanter and further attaching a hopper that is smaller and thinner than the existing side-opening hopper, and the planting method and cultivation method mechanize the planting process in mulch cultivation using a 135 cm wide mulch for leek.
