Description

  The present invention relates to a method for growing a plant that can suppress weeds that grow around the ridge after planting the plant on the ridge.

  When plants are planted on the ridges for cultivation, it is important to perform a control treatment in advance so that weeds do not grow around the ridges.

  As the herbicide used for such weed control, for example, in Patent Document 1 below, rice bran, bran, millet, leeches, rice husk, wood chips, beans, etc. are used as raw materials, and Bacillus subtilis, lactic acid bacteria, spores, actinomycetes, yeasts Has been proposed.

  However, in the method of spraying the above herbicide, especially when the cultivation area is large, the cost of controlling is increased and the economic efficiency is inferior, and for example, a plant in which the drug is not recognized as a herbicide such as Licorice plant There was a problem that it could not be used for cultivation.

  As another weed control method, a method is also known in which a multi-sheet is spread over the entire surface of soil in advance, and a plant is planted in an opening formed in the multi-sheet.

  However, in the method of laying the multi-sheet over the entire surface of the cultivation soil, although it is suitable when the cultivation period of the plant to be cultivated is short, the cultivation requires about one and a half to two years as in the above-described liquorice plant. It cannot be applied to plants that need to be supplied because the supply of water to the soil due to rainfall is interrupted. There was a problem that the sheet was damaged and the growth of weeds could not be suppressed. Further, the multi-sheet capable of withstanding long-term use has a problem that the cost increases.

Rice husks or rice husks can be supplied to the ridges through charcoal. Moreover, even when the weed seeds scatter around the ridge and adhere to the rice husk or rice husk charcoal laid in the ridge, the rice husk or rice husk charcoal has water repellency and a water content. Due to the low germination, the germination of the seed can be suppressed.

  In addition, even if the seeds adhering to the chaff or the chaff charcoal germinate due to rainwater or the like, it can be prevented from reaching the ridges and growing. Here, the thickness over which the rice husk or the rice husk charcoal is spread is preferably 5 cm or more, more preferably 7 cm or more, and even more preferably 10 cm or more.

  In addition, since the above-described rice husk or rice husk charcoal is laid so that the multi-sheet laid from the upper surface of the ridge to both sides is sandwiched between the side of the ridge and the end of the multi-sheet and the side of the ridge. The growth of weeds from the border of can be suppressed.

  Furthermore, if the chaff or the chaff charcoal is laid in the opening of the multi-sheet in which the plant is planted as in the invention according to claim 2, weeds can grow from the soil around the planted plant. Can also be suppressed.

  As a result, germination of weed seeds can be suppressed, and rice husk is an undecomposed organic substance, and rice husk charcoal is an inorganic substance, and is excellent in safety because it does not contain any herbicides. In addition, it is economical because it is inexpensive.

  At this time, in particular, rice husk charcoal is an inorganic substance having a small-diameter porous surface, and microorganisms such as beneficial soil bacteria adhere to the plant to promote the growth of the plant, and also to improve air permeability and drainage. Since the rice husk charcoal has a function, it can be used as a soil improving material by being mixed with the soil after use.

  From the above, the present invention is suitable for the cultivation of herbs in which no herbicides that can be used at the present time are recognized, and can be used more preferably, as in the invention described in claim 3 or 4. Is cultivation of Licorice plants requiring a long growth period of about one and a half to two years.

It is a cross-sectional view of the ridge part for describing one Embodiment of this invention. It is a perspective view which expands and shows a part of upper surface of a ridge. 4 is a photograph showing a result of an example of the present invention.

Hereinafter, an embodiment in which the method for growing a plant according to the present invention is applied to a method for growing a liquorice plant will be described with reference to the drawings.
As shown in FIGS. 1 and 2, in this growing method, first, a plurality of ridges 1 are formed by raising the soil in a streaky manner (about 40 cm) at intervals (about 30 cm). The multi-sheet 4 is laid from the upper surface 2 (about 50 cm in width) of the ridge 1 to both side surfaces 3. Here, the multi-sheet 4 is fixed by covering both ends with soil.

  Next, rice husk or chaff charcoal 5 is laid between the ridges 1 where the soil is exposed, to a thickness of about 10 cm. At this time, the chaff or the chaff charcoal 5 is laid so as to sandwich the end portion 4 a of the multi-sheet 4 between the chaff and the side surface 3 of the ridge 1.

  Before or after this, seeds of a liquorice genus plant were sowed in an opening 6 formed in the multi-sheet 4 located on the upper surface 2 of the ridge 1 in a preliminary growing container or the like (not shown) and germinated and grown to a predetermined size. The planting 7 is planted.

  Next, rice husk or rice husk charcoal 5 is similarly spread around the planted seedling 7 in the opening 6 to grow the planted seedling 7.

  In the method for growing a liquorice plant having the above-described configuration, since the rice husk or the husk charcoal 5 is laid between the ridges 1 where the soil is exposed, the planting seedlings 7 of the liquorice plant settled on the ridge 1 are provided. Rainwater can be supplied to the ridges through chaff or chaff charcoal 5 during the growing of the corn. Therefore, even when growing a liquorice plant requiring a long growth period of about one and a half to two years, supply of water to the soil is not hindered.

  Moreover, since the rice husk or the rice husk charcoal 5 has water repellency and a low water content, the seeds of the weeds scatter around the ridge 1 and the rice hull or the rice husk charcoal laid between the ridges 1 5 can also suppress the germination of the seeds.

  In addition, since the chaff or the chaff charcoal 5 is laid in a thickness of about 10 cm, even if the seeds attached to the chaff or chaff charcoal germinate due to rainwater, etc. The rice husk or the rice husk charcoal layer 5 can be prevented from reaching the ridge 1 and growing.

  Furthermore, since the chaff or the chaff charcoal 5 is laid so that the end part 4a of the multi-sheet 4 laid from the upper surface 2 of the ridge 1 to both side surfaces 3 is sandwiched between the end portion 4a and the side surface 3 of the ridge 1. Weeds do not grow from the boundary between the end of the multi-sheet 4 and the side surface 3 of the ridge 1. In addition, since the chaff or the chaff charcoal 5 is also laid in the opening 6 of the multi-sheet 4 in which the fixed planting seedling 7 of the liquorice plant has been planted, the growth of weeds from the soil in the opening 6 is also suppressed. can do.

  As a result, the germination of weed seeds can be suppressed, and the rice husk 5 is an undegraded organic substance, and the rice husk charcoal 5 is an inorganic substance and does not contain a herbicide, so that it is excellent in safety, In addition, they are economical because they are inexpensive.

FIG. 3 shows the results of an experiment in which rice husks were laid between furrows to grow licorice plants.
As can be seen in FIG. 3, the sprinkler lines do not have rice hulls, so that weeds are often overgrown, whereas weeds are not growing in the furrows with rice husks.
Further, in this experiment, it was found that there was a place where weeds were prosperous because rice husks were not laid at the opening of the multi-sheet in which the fixed seedlings of the licorice plant were planted.

  In addition, in the said embodiment, although the case where the growing method of the plant which concerns on this invention was applied to the growing method of the licorice genus plant was demonstrated, this invention is not limited to this, and is planted in a ridge. The same can be applied to growing various other plants.
