である。FIELD OF INDUSTRIAL APPLICATION This invention relates to a soil for growing seedlings.

いる。[Prior art and problems to be solved by the invention] In recent years,
BACKGROUND ART For the purpose of rationalizing agricultural and horticultural work and increasing the yield of agricultural products, intensive growing of seedlings and transplantation of the grown seedlings using machines have been carried out.
【０００３】このように苗を集中的に生育させ、該生育
苗を移植する方法は、比較的均一で強健な苗を得易く、
また該生育苗は培土の付いたままの状態で移植されるた
め、活着が早く、しかも活着率が高いという点において
賞用されつつある。[0003] This method of intensively growing seedlings and transplanting the grown seedlings makes it easy to obtain relatively uniform and strong seedlings,
In addition, since the grown seedlings are transplanted with the soil still attached, they are becoming prized because they take root quickly and have a high survival rate.

く、移植作業の効率の低下を引き起こす大きな要因とな
っていた。However, in this method, when transplanting the seedlings together with the soil in which they were grown (seedling cultivation soil), the soil at the roots of the seedlings (root ball portion) tends to collapse or the roots are damaged, which reduces the efficiency of the transplanting work. This was a major factor causing the decline in

め混合しておくことを余儀無くされていた。[0005] As a method to solve such problems, a method of adding a polymer to the soil is known, but in this method, the polymer and the soil are mixed in advance for each crop and depending on the purpose of use. In addition, it was necessary to select a combination of these and mix them in advance.
【０００６】さらに、このような方法の一つとして、例

培土の硬度向上を計る方法が知られているが、該方法で
は育苗培土の硬度向上のために、移植前に灌水を停止し
て培土を数日乾燥させる作業が必要であり、よって苗が
ストレスを受けてしまうとの欠点を有していた。Furthermore, as one such method, for example, a method is known in which an acrylamide polymer is added to the seedling growing soil to improve the hardness of the seedling growing soil. Therefore, it is necessary to stop watering and allow the soil to dry for several days before transplanting, which has the disadvantage of stressing the seedlings.
【０００７】また、ポリエチレンオキサイド重合体粉末

合するに際し、培土の水分管理等の種々の制約があった
。[0007]Also, a method of adding polyethylene oxide polymer powder to the soil has been proposed, but since polyethylene oxide polymer powder gels when it absorbs water,
When uniformly mixing polyethylene oxide polymer powder and soil, there are various restrictions such as moisture control of the soil.

。[0008] In these methods, the growth status of the roots of the seedlings and the drying status of the soil tend to be greatly influenced by the natural environment, so it is not always possible to obtain a root ball portion with the desired hardness. On the contrary, the transplantation work may become complicated and the survival rate may be lowered.

明に至った。[Means to solve the problem] Under these circumstances,
The present inventors conducted various studies in order to develop a better seedling growing soil, and found that by treating it with an alginate aqueous solution,
The inventors have discovered that the above-mentioned drawbacks can be solved and that a seedling growing soil with a uniform and stable root ball area can be easily and quickly provided, leading to the present invention.

【００１２】かかるアルギン酸塩水溶液の育苗培土への
処理方法としては、例えばアルギン酸塩水溶液を灌水す

About 5% to 1.0% by weight, preferably 0.1% by weight
~0.5% by weight.
【００１５】本発明によれば、アルギン酸塩の水溶液を
用いることから、アルギン酸塩を育苗培土全体に均一に
分布せしめることが容易であり、しかも育苗培土の固化
速度が速く、根鉢部分の安定した育苗培土が得られる。According to the present invention, since an aqueous solution of alginate is used, it is easy to uniformly distribute alginate throughout the seedling growing soil, and the solidification rate of the seedling growing soil is fast, resulting in a stable root ball area. You can obtain soil for raising seedlings.
【００１６】また、アルギン酸水溶液による処理を移植
作業直前に施せば足りることから、所望の硬度を保持し
た根鉢部分を有する育苗培土が得られ易くなる。Furthermore, since it is sufficient to perform the treatment with the alginic acid aqueous solution immediately before transplanting, it becomes easier to obtain a seedling growing soil having a root ball portion that maintains the desired hardness.

Since it is sufficient to apply it to the soil, it is possible to provide a seedling growing soil having a root ball portion that maintains a desired hardness. Moreover, in the conventional technology,
There is no need to select the soil and polymer depending on the crop and purpose of use, and there is no need to perform uniform mixing in advance, and it is also possible to avoid stress on seedlings and restrictions such as moisture management of the soil.
