Long-acting sustained-release nutritional soil for mechanized rice seedling transplanting and preparation method therefor

Abstract

The invention discloses long-acting sustained-release nutritional soil for mechanized rice seedling transplanting and a preparation method therefor. The nutritional soil is prepared from the following raw materials in parts by weight: 240-260 parts of soil for fields and gardens, 150-170 parts of folium cortex eucommiae residue, 20-22 parts of calcium-magnesium phosphate, 7-8 parts of potassium chloride, 6-7 parts of pearlite, 34-36 parts of wheat straws, 7-8 parts of quick lime, 3-4 parts of glucose, 15-17 parts of urea, 2-4 parts of VA mycorrhiza, 1-2 parts of Bacillus megaterium and a proper volume of water. According to the nutritional soil disclosed by the invention, the raw materials are all clean and pollution-free materials and meanwhile are thoroughly well-composted, so that the nutritional soil is free of pungent smells such as putrefactive odor and the like; and a variety of organic humus slowly releases nutrients in the presence of microbes and an inorganic particle carrier, so as to maintain the activity of the nutritional soil and the alimentary cycle of young seedlings for a long time and play a role in actively promoting the growth of the young seedlings.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a long-acting slow-release nutrient soil for machine-transplanted rice and a preparation method thereof. Background technique [0002] Nutrient soil is a bed soil with strong water and fertilizer retention capacity, loose ventilation, and no pests and diseases prepared to meet the needs of seedling raising and seedling growth. At the same time, the nutrient composition cannot meet the specific growth needs of the seedlings, resulting in damage to the seedlings and insufficient nutrient supply for the early growth of rice. [0003] Because Eucommia leaves are rich in resources and easy to obtain, they have been widely used in the plant extraction industry, resulting in a large amount of Eucommia leaf residues. However, most factories currently deal with Eucommia leaf residues by direct dumping, incineration and landfill. This not only causes a waste of resources, but also pol...
