Efficient slow-released fertilizer for root-rotting-preventing rice in paddy field and preparation method of fertilizer

Abstract

The invention discloses an efficient slow-released fertilizer for root-rotting-preventing rice in a paddy field. The fertilizer comprises the following components: paraffin, calcium peroxide, cinnamon oil, porous calcium carbide, castor leaf powder, betel nut shell powder, animal giblet powder, green tea seed cakes, rice hull biomass carbon, glucose, porous cellulose acetate microspheres, beer yeast, amino acid, inositol, dicyandiamide, polyaspartic acid, medium mineral elements, trace mineral elements, grape procyanidins, hydroxypropyl methylcellulose, hydroxyethyl cellulose, alginate, activated diatomite and the like. The slow-release fertilizer for rice in the paddy field can be prepared by coating fermentation main raw materials with coated liquid capable of dynamically release nutrients, is rich in organic matters and has high fertility; the organic fertilizer adopts the betel nut shell and the rice hull biomass carbon with certain hardness, so the air permeability of the fertilizer is improved and the root rotting phenomenon of the rice in the paddy field can be reduced; and the fertilizer adopts dicyandiamide and polyaspartic acid fertilizer synergists, so the nutrient accumulation of the rice can be increased, the utilization efficiency of the fertilizer is improved and efficient cultivation of the rice is promoted.

Description

technical field [0001] The invention relates to the technical field of agricultural slow-release fertilizers, in particular to a high-efficiency slow-release fertilizer for paddy field anti-corrosion root rice and a preparation method thereof. Background technique [0002] Fertilizer is the food of plants, and it is the largest material investment in the production of plants, especially crops. The long-term use of fertilizers and fertilizers, combined with the comprehensive impact of the soil environment, makes the utilization rate of fertilizers become lower and lower. This is also the use of fertilizers and fertilizers. In addition, unreasonable fertilization has also caused a series of problems such as environmental pollution and threats to the quality and safety of plant and crop products. In the face of these increasingly prominent and more serious problems, it is necessary to improve fertilizer and chemical fertilizers. Taking the road of sustainable development has be...

Problems solved by technology

[0004] The currently developed coating materials use static membrane pores to release nutrients. Usually, the film thickness is adjusted or materials with different properties are used to control the release rate. There are few reports on the control of nutrient release through dynamic membrane pores.
