Therefore, conventionally, when planting woody plants, a large amount of fertilizer has been buried in the soil in advance, or a fertilizer having a slow-release effect by coating the fertilizer with a resin has been used.

それがある。[0004] Further, the resin-coated product significantly increases the cost, and there is a concern that the resin may affect the environment, which may be contrary to the environmental protection act of greening.
【０００５】本発明はこのような課題を解決するために

特徴とするものである。Means and Effects for Solving the Problems The fertilizing method according to the present invention made to solve the above problems is an aqueous acid solution.
It is characterized in that waste cocoons that have been immersed therein are buried in the soil.

ク質は約１５％程度の窒素を含有している。The cocoon is composed of silk protein, which decomposes in the soil to become inorganic nitrogen (ammonia, nitric acid, etc.) and exhibits a fertilizing effect. Silk protein contains about 15% nitrogen.

非常に長期に亘り濃度障害のない持続的な窒素供給が可
能となる。[0008] Here, the decomposition rate of silk protein in soil is slow, and in particular, fibroin, which is the main component thereof, has a very low decomposition rate due to its high crystallinity. Therefore, by burying waste cocoons in the soil, it becomes possible to provide a continuous nitrogen supply as a slow-release nitrogen fertilizer for a very long time without concentration disturbance.

ができる。Further, the waste cocoons may be embedded together with the pupae. Pupae contain proteins and chitin, which also decompose to inorganic nitrogen. Chrysalis are cocoons (fibroin)
Since the decomposition rate is much higher than that, it is possible to obtain both fast-acting and slow-acting effects by embedding them together.

Is a so-called industrial waste in the silk fiber industry, and it is becoming more and more difficult to set up a waste treatment plant,
The processing is a big problem. The present invention reuses the material treated as waste as a raw material, and also contributes to environmental protection in this respect.

現することができるようになる。Before burying the cocoon in the soil, a treatment of immersing the waste cocoon in an acid aqueous solution is performed . By this process,
Since the rate of decomposition of cocoon in soil increases, it is possible to achieve the desired slow-release performance (or quick-release performance) by appropriately adjusting the conditions (acid concentration, temperature, immersion time, etc.) during the treatment. become.

By preliminarily making a sheet-shaped waste cocoon (or pupae-containing waste cocoon) that has been soaked in, the handling becomes very easy, and the fertilization efficiency at the time of tree planting etc. is greatly improved.

を算出した結果が図１である。FIG. 1 shows the results of testing the decomposition rate of waste cocoons and pupae in soil. The test conditions are as follows. Test soil: Soil from Kyoto Prefectural University farm (alluvial paddy soil) Test temperature: 30 ° C (however, only e below 25 ° C) Test product: a. Cocoon only b. Pupae only c. Cocoons treated with 1M hydrochloric acid only (immersion in 1M hydrochloric acid aqueous solution kept at 97 ° C. for 60 minutes) d. Cocoons treated with 0.2 M hydrochloric acid only (immersion in 0.2 M hydrochloric acid aqueous solution kept at 97 ° C. for 60 minutes) e. Powdered cocoon (Fibroin powder produced by the method described in Japanese Patent Application No. 11-229857) Test method: A test soil was put in a bottle, the test material was embedded in the bottle, and the test temperature was maintained in a field state. Measure the amount of inorganic nitrogen contained in the soil at an appropriate time and decompose it (nitrogen mineralization rate)
The result of the calculation is shown in FIG.

素が無機化するにはおおよそ３年程度かかることから、
繭のみの埋設は、緑化工用緩効性肥料として非常に適し
たものとなる。As shown in FIG. 1, in the case of only cocoons, the decomposition rate is very slow, and only about 20% decomposes even after about 200 days. That is, under this test condition, it takes about 3 years for all nitrogen to be mineralized,
The burial of cocoons alone is very suitable as a slow-release fertilizer for revegetation.
【００１５】一方、蛹のみの場合、数日でほとんど分解
する。従って、屑繭と蛹とを組み合わせることにより、
速効性（初期成育に有効）と緩効性の双方の性能を持つ
肥料とすることができる。On the other hand, in the case of only pupae, it almost decomposes within a few days. Therefore, by combining scrap cocoons and pupae,
The fertilizer can have both fast-acting (effective for initial growth) and slow-acting properties.

ことができる。The effect of improving the decomposition rate by the treatment with the hydrochloric acid aqueous solution is clearly shown in FIG. It was also found that the decomposition rate can be adjusted by changing the hydrochloric acid concentration. Therefore, a slow-release fertilizer at an arbitrary rate can be produced by subjecting it to an appropriate hydrochloric acid aqueous solution treatment in advance.

もよい。For example, in a field or the like, a suitable fertilizer can be prepared by increasing the proportion of pupae or by treating with an acid aqueous solution in advance. Note that a strong acid other than the above-mentioned hydrochloric acid (for example, sulfuric acid) may be used for the previous acid aqueous solution treatment.

Straws are embedded in layers at 25 cm intervals in three layers, and the waste cocoons according to the present invention are placed when the second layer is installed. As a result, the cocoon is located about 30 cm below the surface of the earth. Black pine is planted here at 40 cm intervals. The amount of waste cocoons to be buried is 1
It is about 250 g per book. In the second half of the implementation of this method, a clear improvement was observed in the state of Japanese black pine compared to the conventional method using chemical fertilizer. That is, while the yellowing phenomenon of leaves due to lack of nitrogen was observed in the conventional method, the yellowing phenomenon was not confirmed in this fertilization method, and the growth amount itself was excellent.
