Description

TECHNICAL FIELD The present invention relates to a method for growing a creeping licorice in which foliage extends along the ground as it grows.

Licorice plant contains many glycyrrhizin, which is effective for liver damage and allergies, and licorice obtained by drying its roots and rhizomes. Widely used as a raw material. Further, in addition to the above-mentioned glycyrrhizin, glucose and sucrose are also contained, so that they are also used as raw materials for sweeteners.

For example, in the following Patent Document 1, licorice plants are pre-cultivated in a seedling cultivation container to grow licorice roots up to a predetermined size, and a water-impermeable sheet covering a ridge of a predetermined height has a hole for cultivation. Open the liquorice root and plant the licorice root in the ridges through the cultivation holes so that the stems and leaves above it and the growth points of the stron are located above the surface of the ridge. On the other hand, a method for growing a licorice plant has been proposed in which the root part of the licorice plant is grown in a ridge whose water content is controlled so that the root part is mainly enlarged.

By the way, as one kind of the above-mentioned licorice plant, a crawling licorice is known, in which main branches and foliage extend along the ground as it grows.
FIG. 4 and FIG. 5 show a conventional creeping licorice grown on a vine 20 after the roots of the creeping licorice were grown on the ridges 20 after the seedlings of the creeping licorice were grown in a container for preliminary growth. This shows the growing state.

At this time, a multi-sheet 21 is laid on the upper surface of the ridge 20 for water retention, heat retention and weed control of the ridge 20, and an opening 22 formed in the multi-sheet 21 is provided with an ecstasy licorice. Planted seedlings are planted. Then, in the creeping licorice, the main branch 24a extends from the upper surface of the ridge 20 along the lower ridge 23 with the growth.

In such a conventional method for growing creeping licorice, since the surface of the multi-sheet 21 is heated up to about 70° C. by solar radiation, as shown in FIG. There was a problem that it would die.

In addition, the main branches 24a and the foliage 24b extending into the furrows 23 are soiled by the rebound of the soil due to rainfall or are covered with the weeds grown in the furrows 23, and photosynthesis is suppressed, resulting in a decrease in the yield. At the same time, the presence of the grown main branches 24a and the foliage 24b in the furrow 23 makes it difficult to operate the machine in the middle tillage management.

Further, even when water collects in the furrows 23 due to rainfall, photosynthesis is inhibited by flooding the foliage 24b, attacked by pests, and the yield is greatly affected. there were.

It is characterized by growing along the net. Here, the above-mentioned quotation net includes a net formed by stretching a plurality of strings.

The invention according to claim 2 is, in the invention according to claim 1, for sandwiching the main branch and the foliage between the main branch and the foliage of the creeping licorice with the invitation net. It is characterized by arranging nets.

According to a third aspect of the invention, in the invention according to the first or second aspect, a sprinkler pipe is arranged below the invitation net, and from the sprinkler pipe to the back side of the main branch and the foliage of the creeping licorice. It is characterized by spraying pesticides or water toward it.

The invention according to claim 4 is the invention according to any one of claims 1 to 3, in which a multi-sheet is laid on the upper surface of the ridge, and a creeping licorice is provided in an opening formed in the multi-sheet. It is characterized by being planted.

According to the invention as set forth in any one of claims 1 to 4, the main branch of the creeping licorice that grows as it crawls on the ground along with its growth in the natural state is guided to the upper attracting net. Since the foliage growing from now on is inserted through the opening of the quotation net and is grown along the above-mentioned quotation net, the main branches and foliage are soiled by the rebound of the soil due to rainfall or the like, or weeds that have grown in the ridges. The photosynthesis will not be suppressed by being covered with.

In addition, since the main branches and foliage do not extend into the ridges, there is no risk of being flooded into the water accumulated in the ridges or attacked by pests due to rainfall, and the main branches and foliage are stretched above the ridges that are susceptible to sunlight. Since it is arranged on the provided quotation net, the photosynthesis of main branches and foliage can be greatly improved and the yield can be increased.

At this time, according to the invention as set forth in claim 2, since the sandwiching net for sandwiching the main branch and the foliage is arranged between the invitation net and the net, the main branch and the foliage are connected by a string or the like. It is possible to save time and effort to be restrained by the invitation citation net and to effectively function as a measure against strong winds.

By the way, in cultivation of licorice, it has been conventionally said that weeding work accounts for about 47% and pesticide spraying accounts for about 27% of the total work time per 10a. On the other hand, in recent years, the idea of integrated pest management (IPM) has been recommended. With regard to the control of pests (weeds), this aims to take a comprehensive control method by using all available control technologies and combining economic measures with appropriate means.

On the other hand, in the present invention, since the foliage does not extend into the ridges, in addition to facilitating mechanical operation in medium tillage management from the viewpoint of weed management, also in the IPM management, the weed height is It is possible to raise the number of cuttings and reduce the number of cuttings.

Further, according to the invention as set forth in claim 3, a sprinkler pipe is arranged below the invitation net, and the pesticide is sprayed from this sprinkler pipe toward the main branch and the back side of the foliage on the invitation net to kill insects. Therefore, it is possible to efficiently control pests. Further, since it is also possible to spray water from the water sprinkling pipe toward the main branches and the backsides of the foliage on the invitation net to disperse insects and insects, from the viewpoint of the above-mentioned IPM management, effective pest control can be performed. It becomes possible to carry out control.

As a result, especially when the multi-sheet is laid on the upper surface of the ridge and the creeping licorice is planted in the opening formed in the multi-sheet, the mulch having a high temperature is obtained. It is possible to reliably prevent the foliage death of the foliage due to the extension of the foliage on the sheet, and to obtain a remarkable effect.
