Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mulch film for cultivating sweet potatoes, which is used for cultivating climbing root vegetables such as sweet potatoes, Japanese yam, and yam.

[Conventional technology]

Conventionally, sweet potatoes were grown by planting seedlings 3 diagonally in the ground 4 as shown in Figure 3 A, B, and C. However, this method allowed the potatoes to grow only from one point on the underground stem, making mass production difficult. Not only was it unsuitable for cooking, but the potatoes were also prone to bending, reducing their commercial value. For this reason, the fourth
As shown in the figure, insert only one end of the seedling 3 into the ground 4, let the center part crawl on the ground and press the tip with soil 5, and when the tip is erected, roots will come out from the stem above the ground and many potatoes will grow. was discovered to grow straight. Conventionally, in order to perform this planting, the central part of the mulch film was pushed and cut with a thorn wheel.

[Problems that the invention aims to solve] However, this work was tedious, and the holes in the thorn wheel did not allow sufficient air circulation, making the roots easy to swell, resulting in damping-off.

[Means for solving problems]

The present invention was created in view of these drawbacks.
By drilling special long holes in the mulching for sweet potato cultivation, efficient mulching cultivation of sweet potatoes can be carried out rationally, allowing for early harvesting, labor saving, and by aerating the roots, preventing the occurrence of diseases. To provide a mulch film that allows easy planting of seedlings to obtain good results in growing potatoes.

In the present invention, a sheet 1 made of a material such as synthetic resin and extending in one direction has a central part with a length of 15 to 30 cm and a width of 2 to 5 cm.
Long ellipsoidal holes 2, 2, . . . cm in diameter are bored at regular intervals.

[Effect]

When the film according to the present invention is spread on the ground, seedlings can be immediately planted so as to creep on the ground, and since air is sufficiently circulated through the long holes 2 to the roots, damping-off disease will not occur.

〔Example〕

A strip-shaped film 1 with a width of 950 mm as shown in the first diagram.
In the center is an oval hole 2 with a width of 3 cm and a length of 20 cm.
2...... are drilled in a vertical line at 40cm intervals.

This film 1 is a low density polyethylene LL film with a thickness of 0.02 mm to 0.03 mm. Instead of this film, Lo polyethylene, Hi polyethylene,
Paper, oiled paper, cloth, cheesecloth, etc. may also be used. The colors of the film are white, black, and pink. long hole 2,
2... should be an ellipse, an oval, or a rectangle with rounded ends and no corners. This elongated hole 2 is formed by burning out with a high-voltage spark, by stamping, or by other methods.

As shown in FIG.
Insert one end of the seedling into the soil, let the center of the seedling 3 crawl on the ground, and press the tip with soil 5. As a result, as shown in Fig. 2C, a bud 6 grows upward from the center of the stem stretched on the ground 4, a root 7 grows downward, and when the bud grows, an old bud 3a at the tip of the parent stem grows. Excise. This allows a large number of potatoes 8 to grow straight in the center of the stem. The sizes of these potatoes 8 are averaged, there are few bends, and the quality is stabilized.

White film increases soil temperature, while black film suppresses soil temperature and prevents weeds. As seedlings 3, Kintoki, Beniazuma, Benicomachi, Benihayato, etc. were used.

As described above, if the entire field is covered with the film 1, the long holes 2 are made in the areas where the planting is to be done, so there is no need to make cuts, and the long holes 2 allow for good air circulation, which prevents stuffiness, etc. It is possible to prevent the occurrence of various diseases such as damping-off. Also, when harvesting, film 1
Potato 8 can be taken out from the ground by simply rolling it up.

[Effect of idea]

The present invention allows easy and efficient cultivation of vine root vegetables such as sweet potatoes.

[Brief explanation of the drawing]

Figure 1 is a plan view of an embodiment of the present invention, Figures 2A and 2B are a plan view and a vertical cross-sectional view of the seedling 3 when planted, Figure 3A is an explanatory diagram of growth, and Figure 3A, B and Figure 3 are is an explanatory diagram of the conventional planting of seedlings 3, and Figure 4 is an explanatory diagram of the conventional planting of seedlings 3.
It is an explanatory diagram of planting. 1 is a sheet, 2, 2 is a long hole.
