Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to slope greening substrates such as nets and sandbags containing soil activators.

[Conventional technology]

In recent years, there has been a strong desire to green slopes, even in extremely poor conditions, from the perspective of preserving the environment, and for this reason, slow-release fertilizers have come into widespread use.

However, chemical fertilizers alone are not sufficient, and it is necessary to strengthen the soil's natural fertility. For this purpose, effective soil bacteria have come to be used. For example, methods such as Japanese Patent Application Laid-Open No. 134903 of 1981 and Japanese Patent Application Laid-Open No. 150827 of 1988 have been proposed.

[Problems that the invention seeks to solve] In both of the above methods, effective soil bacteria are mixed into the vegetation base material and sprayed onto the slope, but the content of the soil bacteria used is not specified. There are so many types of soil bacteria that it is difficult to say that all of them are effective (and it cannot be said that there is no possibility that some types of bacteria may actually cause harm).

[Means for solving problems]

In order to solve the above problems, this invention has already been proven in the agricultural field, and the types of bacteria have been clarified.
This method uses a soil activator that has suspended the bacteria in a dry state.

Furthermore, this invention focuses on the difference between fields and slopes, and uses this soil activator even more effectively by using a formulation that cannot be applied to fields but can be applied to slopes.

This invention is based on the technology disclosed in Japanese Patent Application Laid-Open No. 208191 of 1981, with the title of the invention "Soil activator".

The basic technology is to add Bacillus cereus to a carrier containing 10% or more of humic acid and 1% or more of protein nitrogen.

This is a soil activator containing a culture of one or more actinomycetes selected from Salbus.

In this invention, as a soil activator, a soil activator cultured based on the above-mentioned basic technology is dried at low temperature to keep bacteria in a state of suspended animation - Bioferti of Kyoritsu Organic Industrial Research Institute
(Product name) is used as its raw material.

In this invention, bioferti is a powdered product;
It cannot be used on slopes as it is (because it is difficult to use it, so it is recommended to use a water-soluble plastic film or other material together with other vegetation base materials).
Store in a bag made of water-soluble paper or water-permeable fabric. The term bag here refers to a wide range of items including paper cylinders and paper boxes. The amount of Bioferty used can be increased or decreased depending on the situation, but is it usually 1rr for vegetation base material? 500g~2kg per
Aim for.

It is preferable to store pulverized carbonized plants such as peat and lignite together with a soil activator in the bag.

It is also desirable to add organic fertilizer powder such as fish meal or soybean meal to the bag.

Next, such a bag body is attached to a substrate such as a slope spreading material such as a net spread on a slope surface, or a vegetation sandbag to be laid on a slope surface. The bag should be attached as uniformly as possible to the entire base. This method is similar to the slope fertilization method proposed by the inventor in JP-A No. 58411 of 1982, but unlike slow-release fertilizers, the soil activator is used in its entirety as soon as possible after application. Since it is necessary to mix the soil activator, it is stored in a water-soluble bag alone or together with powdered carbonized plants and powdered organic fertilizer, and slow-release fertilizers are stored in a separate durable bag.
It is preferable to use two types of bags together.

According to the method proposed by the inventor in Japanese Patent Application No. 187412 of 1987, the above materials were stored in two types of long and thin bags, and both ends of multiple rigid rods such as iron wire were tied together with two ropes. It is also possible to attach the elongated bags to a rope ladder-like base body connected at intervals. A long paper tube can also be used instead of a bag.

Slope spreading materials are limited in type, such as synthetic fiber/synthetic resin nets, wire mesh, or rather similar materials that have traditionally been used when spraying vegetation base materials, and those with vegetation seeds pre-attached to them. isn't it.

A net with such a dry soil activator is spread out on the slope,
On top of that, seeds, fertilizers, organic matter, water retention materials, soil conditioners,
Spray a vegetation base material containing carbonized plants.

In the case of vegetation sandbags, a soil activator may be stored in a planar continuous pouch made by stacking two sheets of paper and dividing them into a grid pattern. Seeds are attached in advance to the back of the sandbag either directly or via paper, and the continuous pouch is attached thereon.

Sandbags are filled with soil generated on site mixed with organic matter, fertilizer, carbonized plants, water retention materials, etc., and spread on the slope.

In addition to conventional materials, it is effective to mix 10% or more of humic acid-rich materials such as peat, grass charcoal, lignite, and bottlings into the blown vegetation substrate and the soil packed into sandbags. Mixing these materials is avoided on farmland, but it is acceptable on slopes.

[Effect]

Since the soil activator used in this invention is packed with dried suspended bacteria, the ingredients are guaranteed to be as they were cultivated at the factory, and effective bacteria are reliably and stably cultivated without being contaminated by contaminants. can be provided to It is possible to solidify the soil activator into small pieces and adhere them to the substrate, but moisture and heat will activate the bacteria, so a method that avoids this is necessary.

Furthermore, since the bag body containing the soil activator is uniformly laid on a substrate such as a net or a sandbag, construction is standardized and convenient.

After applying a dry soil activator to a slope, the suspended bacteria will become active again due to water spraying, natural rainwater, and temperature, but if you use a water-soluble bag, the bag will dissolve, and if you use cloth In the case of bags, bacteria leak and flow out, so bacteria can be widely active.

Protein nitrogen and inorganic nitrogen are necessary for the effective bacteria used in this invention to be fully effective, and organic fertilizers such as fishmeal and soybean meal are suitable as sources of protein nitrogen. In this sense, it is very effective to store dry organic fertilizer powder in a bag together with a soil activator.

On the other hand, Wood Ace (registered trademark) manufactured by Mitsubishi Chemical Industries @ is a large-grain nitrogen-based fertilizer made from isobutylene diurea and can be expected to last several years, making it particularly suitable for use in conjunction with a soil activator. In the case of slopes, it is difficult to apply additional fertilizer, so it is very effective to administer slow-release fertilizers that are effective for a long period of time. Other slow-release fertilizers include Chisso Asahi Fertilizer■
High Control (registered trademark) is effective.

In addition, humic acid is a necessary component for effective bacteria.
Humic acid provides a habitat for bacteria and has the role of adsorbing and retaining nutrients for antibacterial substances, and it is desirable that the soil activator contains 10% or more of humic acid. Carbonized plants such as peat, grass charcoal, lignite, and botany contain high concentrations of humic acids and are economical. These carbonized plants are difficult to spread in fields, but
In the case of slopes, it can be sprayed without worrying about repercussions. It is extremely effective to add 10% or more of carbonized plants to the vegetation base material used for spraying or to the mixed soil in sandbags. Bottle piles and peat.

Of course, there is no need to add it in the case of local greening. From the same point of view, it is also highly effective to place finely ground carbonized plants in a bag together with a soil activator.
