摘要： PURPOSE:To increase fertilizer response by applying alginic acid oligosaccharide (AO) to field crop, lawn, other planting, etc. CONSTITUTION:This is a fertilizer response-promoting agent containing AO as active component or holding AO on a carrier (e.g. active carbon) or a fertilizer response-promoting fertilizer composed of a fertilizer and AO. A compounding ratio of AO in the fertilizer response-promoting fertilizer is 0.1-5.0 pts.wt. based on 100 pts.wt. of a liquid fertilizer and 0.01-1.0 pts.wt. based on 100 pts.wt. of a solid fertilizer. Fertilizing amount is 10-500ppm in the case of liquid fertilizer and 40-4500g every 10 are in the case of solid fertilizer, in terms of AO respectively. These materials are each used by spraying on leaves, mixing into irrigation water, adding into water of water culture or directly applying on soil. AO is an oligosaccharide composition obtained by decomposing alginic acid, sodium alginate, or algae such as tangle or polysaccharide produced by microorganisms containing alginic acid in the presence of an enzyme such as alginic acid lyase or hydrolyzing these materials with an acid such as hydrochloric acid.

摘要： PURPOSE:To improve the freeze-resistance of farm crops such as tea, leaf vegetables, root vegetables and fruits by applying an alginic acid oligosaccharide to the plant or the soil. CONSTITUTION:An alginic acid oligosaccharide composition composed of gluronic acid and/or mannuronic acid and having a degree of polymerization of 2-20 is directly applied to a crop or applied to soil. In the case of a winter- harvesting crop such as cabbage, the composition is applied preferably during the period from the sowing to a nursery bed to the transplantation to a paddy field or at the transplantation or before the start of head formation. For a crop susceptible to frost injury, the composition is preferably applied 1-2 months before the sprouting of new sprout or the period having frost injury risk. The concentration is preferably 100-1,000ppm in the case of applying the composition in liquid form e.g. by irrigation and the rate of application is preferably 1-7.5kg per 1ha in terms of solid.

摘要： PROBLEM TO BE SOLVED: To improve infection ratio of mycorrhizal fungi to plant roots and improve growth of farm products and qualities of fruits by applying a specific sugar singly or together with mycorrhizal fungi. SOLUTION: Alginic acid oligosaccharide is applied singly or together with mycorrhizal fungi. Alginic acid oligosaccharide is obtained by using alginic acid, sodium alginate or algae containing alginic acid such as tangle weed, etc., a polysaccharide derived from a microorganism, etc., as raw materials and decomposing them with an enzyme such as alginic acid lyase, etc., or an acid such as hydrochloric acid, etc. The concentration of alginic acid oligosaccharide is preferably 10-500ppm, especially about 50-100ppm. As the mycorrhizal fungi, those capable of forming endogenous and/or exogenous mycorrhizae or pseudo-mycorrhizae are preferable and Acaulosprora, Entrophospora, etc., are cited.

摘要： PURPOSE: To provide a method for culturing an orchid, capable not only promoting growth and development of orchid or improving qualities but also lightening injury of root caused by root pruning stress, by using an alginic acid oligosaccharide and to obtain a culture enhancer for orchid. CONSTITUTION: This method for culturing an orchid comprises promoting growth and development of orchid, obtaining high-quality flowering stock in high yield to shorten a growing period and lightening and preventing injury of root by root pruning stress by applying an alginic acid oligosaccharide in culture of an orchid. This culture enhancer of orchid contains an alginic acid oligosaccharide. The alginic acid oligosaccharide is an oligosaccharide composition obtained by decomposing alginic acid, sodium alginate or an alga such as tangle containing alginic acid or a polysaccharide derived from a microorganism with an enzyme such as alginate lyase or hydrolyzing them with an acid such as hydrochloric acid. The culture enhancer is obtained by diluting the alginic acid oligosaccharide as it is or premixed with a fertilizer and manure and an agrochemical and made into a formulation.

摘要： PURPOSE:To provide the subject culture soil permitting the good growth of the roots of a plant and the production of seedlings having high qualities and high performances due to the gradual collapse of the granules of the culture soil by adding a natural polysaccharide to a raw material consisting mainly of soil, granulating the mixture and subsequently drying the granules. CONSTITUTION:The objective product is characterized by adding a natural polysaccharide (e.g. alginic acid, guar gum, inulin, carrageenan) preferably in an amount of 0.1-1wt.% to a raw material consisting mainly of soil, granulating the mixture and subsequently drying the granules. The product is obtained by adding the natural polysaccharide to the raw material consisting mainly of the soil and simultaneously granulating the mixture e.g. with a drum type granulating machine, sieving the produced granules into the sizes of 0.1-5mm and, if necessary, drying the sieved granules.
