[Prior art]
Conventionally, seedling pots widely used and widely used for raising seedlings of flowers and vegetables are, as is well known, formed by bulging a black vinyl chloride thin film sheet into a small flowerpot shape by blow molding means or the like. . The seedbed for sowing paddy and cultivating rice seedlings consists of a seedbed for directly seeding paddy on ridges made in rice fields, and a low-tray wooden box or synthetic resin tray with a uniform thickness. Nursery beds are known in which seeds are put and seeds are sown thereon.
[0003]
[Problems to be solved by the invention]
Although the former seedling pot made of synthetic resin sheet has the advantage of being inexpensive, it cannot absorb intake and nutrients from the pot wall. Because it is necessary to wait, it is difficult to grow above a predetermined size and the growth is stagnant, and it is necessary to remove the seedlings from the seedling pot when growing seedlings are replanted in the field or other large pots. Sometimes the roots of the seedlings are damaged, which can temporarily hinder growth after replanting, and disposal of seedling pots that are no longer needed after use can lead to environmental and environmental pollution such as air and soil pollution. There were concerns that they would cause problems.
[0004]
Also, in the latter case of a nursery in which paddy is directly sown on the ridges of a rice field, there is a problem that the work of picking and planting the cultivated seedlings (rice planting) has to be performed manually. In the case of nursery beds that are sown in resin trays, it is difficult to obtain the floor soil to be put into wooden boxes and trays, and if you make your own, it takes a lot of trouble, and it is not easy to spread the floor soil to a uniform thickness, It is known that a temporary growth stop phenomenon occurs after a rice planting operation of a growing seedling by a rice transplanter.

Since the pots after molding contain these wood vinegar and bamboo vinegar, they can be buried in the soil from the beginning of the seedling raising or after the seedlings have been properly grown, without being taken out of the pot. When growing is continued, there is an advantage that the period in which the seedling growing pot 1 itself decomposes in the soil can be extended for an arbitrary period.
[0026]
That is, in the case of each pot molding material shown as the first embodiment to the fourth embodiment, in a case where the wood vinegar liquid or the bamboo vinegar liquid is not mixed, watering or fertilizer liquid is sprayed on the ground. When raising seedlings while growing, the period of maintaining the individual shape as a pot is about 6 weeks to about 2 months, and after 3 months the form collapses and hinders carrying, and the decomposition period in the soil There is only about 20 to 25 days, so the original fertilizer put in the pot flows out into the soil with watering, the seedlings cannot absorb the nutrients originally planned, the rooting of the seedlings is poor, and the growth of the seedlings is hindered. Was a distant cause to come.
[0027]
However, in the case of pots formed from the pot molding materials shown in the first to fourth embodiments in which wood vinegar or bamboo vinegar is mixed, the pots have individual shapes during the seedling period on the ground. It can be extended from 3 months to 6 months to maintain and maintain its shape without any hindrance to carrying. In addition, the disassembly period in soil can be extended from 40 days to 50 days. Thus, it is possible to obtain a pot having an advantage that it can be used as suitable for the type of seedling and the growing period.
