PURPOSE:To contrive the growth of plants in water and on the ground area to be immersed in water for a given period by a method in which fine particle- mixed agglomerates consisting of water, air, and clay containing fertilizer are formed and covered with a specific water-resistant gel substance. CONSTITUTION:A sludgy mixture is formed from viscous soil such as clay, fertilizers, coagulants such as anionic polyacrylamide, and water. The sludgy mixture is sprayed onto the slope 2 of the ground 1 to be immersed in water seasonably, such as dam, where the mixture undergoes a higher agglomerating reaction in the presence of air as catalyst to form dehydrated plastic agglomerates 4 and a vegetating base 3 with voids 5. A mixed aqueous solution of an alkali silicate and Na-type silica sol colloidal silica or any one of the aqueous solutions and a hardener aqueous solution of a bicarbonate are sprayed onto the surface of the base 3 by a two-liquid sprayer to cover the hydrophilic agglomerates with the silica gel compounds. The run-off of the base can thus be prevented by easing the impact of water during water-immersing period and the drying of the base during non-immersing period can also be prevented. The vegetation by growth of plants can be attained. |
