こんだ。<Embodiment 7> The ground in the same place is divided into a "treated zone" and a "non-treated zone", each of which is 24 m long.
The size is 2 (3m x 8m). In the treatment section, the following treatment was performed according to the present invention described above. * The size of hole 1 is 15 cm in diameter and 60 cm in depth. * The setting interval of hole 1 is 100 cm. * The number of holes 1 is 48. * Cylinder 4 A cylinder made of vinyl chloride with 4 mm diameter holes at 1 cm intervals is used. * What was put in a cylinder Kawasuna + Burk + "Land Power" (above) was put in a hemp bag that was large enough to contact the inner wall of the cylinder, and this was put in the cylinder. * Effectiveness test 2 after the 32mm rain stopped
A drainage effect test was conducted after a lapse of time. There is no water pool on the surface of the treated area and it can be used. Untreated area There was a pool of water with a depth of 1.5 to 2.0 cm, and the shoes sank into the mud 2.0 to 3.0 cm when walking.

Treatment was carried out on a weakened cherry tree planted in a 5 m long concrete garden stake 5. A hole with a diameter of 10 cm and a depth of 1.2 m was drilled at four locations, and green bamboo was cut into the hole. Each green bamboo is packed with peat moss, and "land life" 15cc is 3000cc.
What was diluted with water (200 times liquid) was injected. No small holes were made on the side of the bamboo. This treatment helped Sakura recover its vigor. As shown in this embodiment, the hole 1 may not only be vertically formed, but may be inclined. It is preferable to cut off the green bamboo in the portion protruding above the ground in FIG. 2 (a), but it does not get in the way as it is because it is inside the garden stake.
