Embodiment 1

[0045] This embodiment provides a biochar-based fertilizer containing clothianidin and a preparation method thereof, comprising the following steps:

[0046] Step 1. Preparation of biochar

[0047] Take bagasse, soak it in potassium permanganate solution, stir for 3 hours, filter and dry to obtain a solid mixture. In potassium permanganate solution, the solid-to-liquid ratio of permanganate to water is 1:20.

[0048] Add the above solid mixture into the ceramic crucible, seal it with a cover and burn it in a muffle furnace, and control the filling density at 0.5 / m 3 ;Heat up to 200°C at a heating rate of 10°C / min, hold for 2 hours, and perform pre-carbonization; then raise the temperature to 550°C at the same heating rate, and perform pyrolysis and carbonization for 3 hours; when the temperature drops to 60°C, the material is discharged, broken, and processed 40 mesh sieve, sealed and stored for later use.

[0049] Step 2. Preparation of biochar-based medicinal fertilizer ...

Embodiment 2

[0054] This embodiment provides a biochar-based medicinal fertilizer and its preparation method, which are basically the same as in Example 1, the difference being that in the biochar-based medicinal fertilizer, the raw materials and their mass percentages are:

[0055] 50% biochar, 1% clothianidin, 20% amino acid raw powder and 5% lignosulfonate, and the balance is clay.

Embodiment 3

[0057] This embodiment provides a biochar-based medicinal fertilizer and its preparation method, which are basically the same as in Example 1, the difference being that in the biochar-based medicinal fertilizer, the raw materials and their mass percentages are:

[0058] 50% biochar, 10% clothianidin, 20% amino acid raw powder and 5% lignosulfonate, and the balance is clay.

Abstract

The invention relates to a biochar-based organic pesticide fertilizer containing thiamethanide. The biochar-based organic pesticide fertilizer is prepared from the following raw materials in percentage by weight: 10% to 80% of biochar, 0.01% to 20% of thiamethanide, 10% to 30% of compound amino acid, 1% to 20% of adhesive, and the balance of filler. The biochar-based organic pesticide fertilizer has the advantages that the effects of fertilizer and pesticide are lasting, the safety in use is realized, the time is shortened, and the labor intensity is decreased.

Description

technical field [0001] The invention relates to the field of organic medicinal fertilizers, in particular to a biochar-based medicinal fertilizer containing clothianidin and a preparation method thereof. Background technique [0002] my country is a large agricultural and populous country, and has long relied on pesticides and fertilizers to increase crop yields. The effective use of pesticides and fertilizers largely determines the increase in crop production and income. At present, in order to improve the utilization rate of pesticides and fertilizers, batches are generally adopted, and pesticides and fertilizers are applied to crops at different stages to promote their yield increase. On the one hand, this method increases the input of manpower and material resources, and increases the cost; on the other hand, because it is difficult to carry out in-ground operations to prevent and control insect pests in the later stage of high-stalk crops, the above-mentioned method is...
