Embodiment 1

[0045] The formula composition of the biochar-based organic fertilizer provided in this example is as follows (by weight): 50% of biochar, 45% of urea, 4.9% of sodium carboxymethylcellulose, and 0.1% of thiamethoxam.

[0046] The preparation method is as follows:

[0047] After the biochar and urea are pulverized evenly, pass through a 40-mesh sieve; then weigh the raw materials according to the above ratio, add them to the mixer, and mix them evenly to obtain a mixed material; then add water to the mixed material until the water and the mixed material The mass ratio is 0.3:1, and after stirring evenly, the water-containing material is obtained; the water-containing material is sent to the granulator for granulation, and the granulated fertilizer is sent to the dryer, and dried at 60°C for 24 hours to obtain the above-mentioned Biochar-based organic fertilizer.

[0048] In this example, the preparation method of biochar is as follows: fill bagasse into a porcelain crucible, s...

Embodiment 2

[0050] The formula composition of the biochar-based organic fertilizer provided in this example is as follows (by weight): 50% of biochar, 45% of urea, 4.5% of sodium carboxymethylcellulose, and 0.5% of thiamethoxam.

[0051] The preparation method is the same as in Example 1.

Embodiment 3

[0053] The formula composition of the biochar-based organic fertilizer provided in this example is as follows (by weight): 50% of biochar, 45% of urea, 4% of sodium carboxymethylcellulose, and 1% of thiamethoxam.

[0054] The preparation method is the same as in Example 1.

Abstract

The invention relates to a charcoal-based organic medical fertilizer, and a preparation method and application thereof. The organic medical fertilizer comprises the following raw material components in percentage by weight: 0.1%-20% of thiamethoxam, 20%-80% of biomass charcoal, 10%-50% of urea and 1%-15% of an adhesive. The preparation method of the organic medical fertilizer comprises the following steps: uniformly mixing the biomass charcoal, the urea, the adhesive and the thiamethoxam to obtain a mixed material; adding water into the mixed material and uniformly carrying out stirring to obtain a water-containing material; and granulating the water-containing material, and carrying out drying to obtain the organic medical fertilizer. According to the organic medical fertilizer disclosedby the invention, thiamethoxam, biomass charcoal and urea are combined, and the three components can achieve an interaction synergistic effect, so that the insecticidal effect and fertilizer efficiency are obviously improved, and simultaneous reduction of farmland chemical fertilizers and pesticides can be achieved. Meanwhile, the lasting period of the pesticides and fertilizers can be prolonged,crop growth is effectively promoted, the crop yield is increased, and the farmland application amount and application frequency of fertilizers and pesticides can be reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural pesticides and fertilizers, in particular to a biochar-based organic fertilizer and its preparation method and application. Background technique [0002] Sugarcane is the most important sugar crop in the world, and my country's sugarcane planting area ranks third in the world. The main sugarcane production areas in my country are mainly concentrated in the southwestern border areas. Among them, Guangxi and Yunnan are the largest sugar cane production bases in my country, with planting area and output accounting for more than 90% of the country's total; these areas are also areas inhabited by ethnic minorities, and their economic development is relatively Lag, the sugar industry is an important economic pillar industry and an important channel for farmers' income. Increasing sugarcane production is of great significance to the local economy and farmers. In addition, sugarcane is also an impor...
