Description

Seeding method and seeding sheet used for the sowing method {method for sowing seed and sheet used for the same}

The present invention relates to a seeding method such as seeding rice seed of rice into paddy field and a seeding sheet used in the seeding method.

Domestic rice farming has traditionally been widely practiced to transplant rice seedlings into seedlings, germinate, and transplant rice seedlings into rice paddy fields such as moss.

In addition, in the case of planting in this way, recently, a sheet of paper having a plurality of holes is laid in the paddy field, and the seeded hairs collected from the hair nursery are planted in the paddy field through the hole of the sheet made of paper, The so-called paper multi-farming method which prevents weed from growing in the said sheet | seat made of paper is also proposed.

In addition, a direct farming method is also known in which rice seed is sown directly in rice paddies without the above-mentioned seeding.

Moreover, in rice paddy farming, a method of preventing frost and keeping warm by planting a vinyl sheet in the paddy field and then germinating and growing to some extent is carried out to remove the plastic sheet from the paddy field.

Moreover, in the same way, in the case of non-farming, the method which uses the sheet | seat which consists of biodegradable resin instead of the said vinyl sheet is also performed.

However, the above-described conventional farming methods have the following problems.

First of all, traditional farming methods for planting require hair-growing and planting, as well as the spreading and weeding of herbicides.

In addition, in the paper multi-farming method, hair raising work and seeding are burdened in terms of labor force.

In addition, the direct wave farming method requires the spreading and weeding of herbicides.

Further, in field farming, a method of laying a vinyl sheet for preventing frost and keeping warm requires a lot of labor for sowing, and also requires spraying and weeding of herbicides.

Further, in field farming, the method of laying the biodegradable resin sheet for preventing frost and keeping warm requires much labor for seeding work as in the case of vinyl sheets, and requires the spreading and weeding of herbicides.

An object of the present invention does not require hair growth and seeding, and does not require the spreading and weeding of herbicides by preventing weeds from spreading, and moreover, a seeding method and a sowing method that can reduce the labor of seeding work It is providing a seeding sheet for use in the method.

In order to achieve the above object, the present invention is configured as follows.

The seeding method of the present invention is seeded by covering and laying a rice paddy so that weeds do not grow on the seeding sheet to which a plurality of rice seeds of rice are attached at intervals.

In the seeding method of the present invention, a seeding sheet is laid in a state in which water is removed from the rice paddy, and when the hair grows after germination, the rice paddy is watered.

In the seeding method of the present invention, a sheet made of paper attached with a plurality of seeds of the field crops at intervals is laid so as to cover the field so that weeds do not grow.

In the seeding sheet of the present invention, a plurality of rice seeds of rice are affixed, and the rice paddies are laid and covered.

The seeding sheet of the present invention is formed in a long shape and wound in a roll shape, and unrolled in a roll shape and placed in a rice field.

In the seeding sheet of the present invention, rice seeds of rice are arranged in a predetermined number of grains at regular intervals from each other.

The seeding sheet of the present invention has light shielding properties.

The seeding sheet of the present invention is made of paper.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 4.

1 shows an embodiment of the seeding sheet of the present invention.

The seeding sheet 1 is made of a suitable material, for example, paper, is formed in a long shape, and is wound in a roll shape around the mandrel 2. Towing portions such as the towing strap 3 are coupled to the mandrel 2 protruding from both ends of the roll-shaped seeding sheet 1. This towing strap 3 is for towing while the worker 4 grabs it and rolls the roll-shaped seeding sheet 1 onto the paddy field 5.

In addition, about laying the seeding sheet 1, you may use a machine regardless of a manpower.

The width W of the seeding sheet 1 is not particularly limited. However, if the width W of the seeding sheet 1 is too narrow, it is not preferable because the number of reciprocation of the rice paddies is increased while laying. This is not desirable because the burden of labor on laying increases. Therefore, in order to minimize the labor of laying work, for example, 160 cm is most suitable.

In addition, the seeding sheet 1 may be rolled up without using the mandrel 2, and each sheet may be relatively short in shape without being rolled, and the seeding sheet 1 May be provided so as to cover the entire rice field 5).

In addition, the towing portion may be made of a metal wire member or a wooden cross member or the like instead of the towing strap 3, and also allows the worker 4 to easily grasp the tow strap, the wire member or the cross member. A grip may be provided.

As shown in Figs. 1 to 4, the seeding sheet 1 is composed of two layers of surface paper 6 and inner paper 7, and the surface paper 6 and the inner paper 7 are light seed. They are attached to each other with (8) sandwiched.

The surface paper 6 is made of a material and a thickness so as to have a light shielding property to sufficiently block sunlight, so that weeds cannot grow.

The surface paper 6 is perforated with an opening 10 to which the support 9 is attached at a position where the rice seed 8 is arranged. This opening 10 is for preventing the growth of the parent (not shown) by the surface paper 6. The support 9 is made up of the surface paper 6 and is provided over the opening 10 so as to support the rice seed 8 between the inner surface paper 7.

There is no particular restriction on the size of the opening 10, but if it is too small, the surface paper 6 may inhibit the mock growth, and if too large, weed may grow in the opening 10. As a suitable size of the opening 10, the length b may be 14 mm and the width c 19 to 19 mm, including the support 10 whose width a is 4 mm, for example.

The inner paper (7) is thin and weak material is used, the root of the germinated hair is to be able to easily penetrate through.

Recycling of both the surface paper 6 and the inner paper 7 or one of them can contribute to the recycling of resources.

As the surface paper 6 and the inner paper 7, it is preferable to employ a non-hazardous solvent such as a chlorine-based solvent in the manufacturing step in order to prevent damage to the medicine against the paddy field 5.

The rice seeds 8 are arranged on the seeding sheet 1 at a predetermined number of grains, for example, one grain at a predetermined interval S from each other in the longitudinal and horizontal directions.

Although there is no restriction | limiting in particular about the dimension of the said predetermined | prescribed space | interval S of rice seed 8 comrades, If the said predetermined space | interval S is too narrow, the space | interval between rice and rice will become dense and nutrients per aeration will be reduced, In addition, as a result of blocking some of the sunlight, it inhibits the growth, but rather decreases the yield, and if it is too wide, the distance between the rice and the rice becomes too far and the yield is reduced. Do.

In addition, the seeding sheet of the present invention may be structurally formed in addition to the above two-layer structure, for example, in a one-layer structure or a three-layer structure or more. Of course, the size, the method of pasting, etc. are not limited to this embodiment, of course.

In the seeding method using the seeding sheet 1 as described above, as described below, no seeding and raising work are required, and the work force of the seeding work is reduced by preventing weeds from growing.

First, the water is drained from the paddy field 5, and the worker 4 enters the paddy field 5 and walks by holding the towing strap 3 in a state in which the surface of the paddy field 5 has no or little water. (5) While rolling the roll-type seeding sheet 1 on the sheet, the seeding sheet 1 is released, and the rice field 5 is covered and laid.

Start laying work from one end of the paddy field 5 to reach the other end of the paddy field 5, and when the laying of one granule is finished, the seeding sheet 1 is cut with scissors or a cutter, and the neighboring ridges are laid. To start.

When laying, when the left and right ends of the seeding sheets 1 adjacent to each other overlap each other, weeds are prevented from growing between the gaps with the adjacent seeding sheets 1.

There is no particular restriction on the overlapping dimension (d), but if it is too narrow, the ends of the seeding sheet 1 may be curled to expose the soil and grow weeds. If the width is too wide, the width of the seeding sheet 1 may be increased. Since W) is unnecessarily widened, it is preferable to overlap about 10 cm, for example.

If a stake or a weight is placed on the seeding sheet 1, the seeding sheet 1 is prevented from being blown or matted by wind or the like.

In this way, the worker 4 repeats the laying of the rice pads 5 by reciprocating the rice paddies 5 to complete the laying of the seeding sheet 1 over the whole of the rice paddies 5.

The rice seed (8) is rooted through the inner paper (7) to take root down to the soil, and grow through the germination through the support (9) of the surface paper (6). Since the seedlings grow in the openings 10 of the seeding sheet 1, the growth is not inhibited by the surface paper 6.

Since water is drained to the rice field 5 as mentioned above before laying the seeding sheet 1, water supply only depends on rainwater until a hair grows to some extent after germination.

The reason for draining water to the rice field 5 is that if the rice field 5 is filled with water when laying the seeding sheet 1, the mock roots may deteriorate or the rice seed 8 may decay.

When the mother grows to some extent, water the rice field (5).

In the case of using the seeding sheet 1, as described above, only the seeding sheet 1 can be laid so that seeding at a predetermined interval can be carried out. Thus, labor for seeding work is greatly reduced.

In addition, since the seeding sheet 1 covers the paddy field 5, it prevents weed seeds from mixing from the surface of the soil and prevents weed growth by preventing weed growth. Weeding is unnecessary. Composting is not necessary because it does not disperse herbicides and destroy soil nutrients. In addition, the destruction of the ecosystem is prevented because the activity of microorganisms is not lost by not dispersing herbicides. Moreover, the infiltration of herbicide into the groundwater and the outflow to agricultural water, etc. are eliminated, and the environmental destruction is prevented. In addition, herbicides are prevented from adhering to the harvested rice.

In addition, when the seeding sheet 1 covers the paddy field 5, generation of harmful nitrous oxide gas from the nitrogenous fertilizer can be suppressed.

The seeding sheet 1 is made of paper, and when harvesting the rice field 5 after harvesting the rice, the seeding sheet 1 is finely cut and diffused into the soil, so recovery is unnecessary.

(Example)

An embodiment of the present invention will be described next.

[Investigation target]

For the following Comparative Examples 1 to 3 and Example 1, the amount of rice seed and the yield were investigated.

Comparative Example 1

Three to five bags of hair were planted at intervals of 30 cm x 15 cm.

(In case of planting with a planting machine)

Comparative Example 2

Rice seeds were scattered regardless of the spacing.

(We correspond to case by straight wave method)

Comparative Example 3

Planted at intervals of one or two batches.

(When we planted by hand)

Example 1

Each egg was planted at regular intervals (15cm × 15cm).

(For seeding of the present invention in which one rice seed is arranged at predetermined intervals in the horizontal and horizontal directions

Corresponds to the case of using a sheet)

[result]

The results of rice seed number and yield of Comparative Examples 1 to 3 and Example 1 are as follows.

Each of the above results can be evaluated as follows.

According to the comparative example 1, the yield is 8 islands and many are good, but a lot of rice seed is also needed as 75,000 eggs.

In Comparative Example 2, the yield was the smallest at 7 islands, but the most significant result was rice seed having 150,000 grains.

In Comparative Example 3, the yield is 9 islands, but the rice seed is relatively large, 45,000 eggs.

In Example 1, the yield was 8 islands and the rice seed was the lowest with 38,000 eggs.

[conclusion]

From the evaluation, the following conclusions were obtained.

Yield was not dependent on the number of rice seeds, but on farming.

By using the seeding sheet as in Example 1 sowing seedlings at a predetermined interval by one grain was able to obtain a large yield with a minimum of rice seed. Looking only at the relationship between the number of rice seeds and the yield, it is comparative example 3 that is relatively close to Example 1, but according to Example 1, since it does not require planting, compared to comparative example 3, the labor burden is greatly reduced.

Therefore, according to the seeding sheet of Example 1, it became clear that a large amount of yield is realized by comparatively low rice seed number by the smallest labor force.
