Abstract

The invention discloses a bidirectional control fertilizer specially used for rice and a preparation method thereof and belongs to the technical field of fertilizer. The bidirectional control fertilizer specially used for rice is prepared from urea, potassium chloride, diammonium phosphate, plant ash, silicon powder, trace elements, calcium superphosphate, humic acid, potassium sulfate, river mud,fish leftovers, a compound microorganism bacterium agent, oyster shell powder, a synergist, polyoxyethylated castor oil, polycaprolactone and lignin-paracresol according to a certain weight ratio. The fertilizer is scientific and reasonable in formula, rapid nutrient release and slow nutrient release are combined, fertilizer requirement laws of the rice in each growth period are really met, and fertilizer utilization rate is increased. Meanwhile, the fertilizer contains inorganic nutrients and also contains a large amount of beneficial microorganism nutrients, multiple beneficial bacteria aresynergistic, plant resistance and root nutrition absorption can be obviously improved, control effect on plant diseases and insect pests of the rice can be excellent, rice yield is effectively increased, and the bidirectional control fertilizer disclosed by the invention also has a function of improving soil.

Description

technical field [0001] The invention relates to a special fertilizer for rice, in particular to a special fertilizer for two-way regulation rice and a preparation method thereof. Background technique [0002] Fertilizer occupies a very important position in agricultural production and is the largest material investment in agricultural production. my country is a large agricultural country with a huge amount of fertilizer use. However, due to the unreasonable application of fertilizers and the leaching, transformation, and volatilization of chemical fertilizers in the soil, the nutrient utilization rate of chemical fertilizers in my country is low, which not only causes a huge waste of resources, And it will seriously pollute the environment on which people live. Controlled-release fertilizer is a new type of fertilizer that can controllably adjust the nutrient release rate and has high technical content. The supply of nutrient elements in fertilizers is basically synchroniz...
