Abstract
The invention belongs to the technical field of soil conditioners, and particularly relates to an antibacterial microorganism soil conditioner and a preparation method thereof, wherein the antibacterial microorganism soil conditioner comprises the following raw materials in parts by weight: 50 parts of ammonium bicarbonate, 20 parts of urea, 5 parts of wollastonite, 5 parts of nitrification inhibitor, 10 parts of humic acid, 5 parts of water-fixing agent, 0.2 part of bacteriostatic agent, 2 parts of microbial bacteria, 2 parts of urease inhibitor, 5 parts of trace elements and 5 parts of carboxymethyl chitosan. According to the invention, the nitrification inhibitor can inhibit nitrogen in the soil from being converted into nitrate nitrogen and nitrite nitrogen, so that the loss of the nitrogen is obviously reduced, the productivity of the farmland is improved, the nitrogen in the soil can be fixed through the bacillus polymyxa, the loss of the nitrogen is avoided, the farmland is ensured to have a good ecological environment, soil-borne diseases can be prevented and treated, and the effects of obviously promoting growth, improving yield and improving quality are achieved; the loss of water in the soil of the semiarid region can be reduced through the water-fixing agent, so that the productivity of the farmland can be improved.
Description
Technical Field
The invention relates to the technical field of soil conditioners, in particular to a soil conditioner for inhibiting bacteria microorganisms and a preparation method thereof.
Background
Cultivated land in semiarid regions of China accounts for 22 percent of the cultivated land area in China, and is an important region for commodity grain output in China. The grain yield in the region is improved, and the method is particularly important for the grain safety in China. However, in semiarid northern climates, soil nitrification is strong, applied nitrogen is rapidly converted into nitrate nitrogen and nitrite nitrogen under the action of nitrifying bacteria and nitrite bacteria, so that environmental problems such as nitrate leaching, nitrous oxide emission and the like are caused, the loss of nitrogen is up to more than 40% of the total nitrogen application amount, and the productivity and ecological functions of farmlands are seriously threatened. Therefore, how to control the loss of nitrogen through the nitration process is an urgent need for protecting and improving the cultivated land quality of the northern semiarid region, guaranteeing the national food safety and promoting the green development of agriculture in the region.
Disclosure of Invention
Technical problem to be solved
Aiming at the defects of the prior art, the invention provides a soil conditioner for inhibiting bacteria microorganisms and a preparation method thereof, and solves the problems in the background art.
(II) technical scheme
The invention specifically adopts the following technical scheme for realizing the purpose:
an antibacterial microorganism soil conditioner comprises the following raw materials in parts by weight: 50-70 parts of ammonium bicarbonate, 20-30 parts of urea, 5-10 parts of wollastonite, 5-10 parts of nitrification inhibitor, 10-20 parts of humic acid, 5-15 parts of water-fixing agent, 0.2-0.5 part of bacteriostatic agent, 2-6 parts of microorganism bacteria, 2-5 parts of urease inhibitor, 5-10 parts of trace elements and 5-10 parts of carboxymethyl chitosan.
Further, the nitrification inhibitor is any one of 2-chloro-6- (trichlorotoluene) pyridine, dicyandiamide and 2-methyl-4, 6-bis (trichlorotoluene) s-triazine.
Further, the humic acid is any one or combination of fulvic acid, ulmic acid and humic acid.
Further, the water-fixing agent is a mixture of sodium polyacrylate, ammonium polyacrylate and modified cellulose.
Further, the bacteriostatic agent is one of wormwood, clove, lavender, rosemary and thyme essential oil.
Further, the microorganism bacteria are a mixture of bacillus polymyxa and bacillus subtilis.
Further, the urease inhibitor is any one or more of hydroquinone, thiourea and n-butyl thiophosphoryl triamide.
Further, the trace elements are a combination of a plurality of iron, calcium, magnesium, zinc, molybdenum and selenium.
The invention also provides a preparation method of the antibacterial microorganism soil conditioner, which comprises the following steps:
s1: accurately weighing corresponding parts by weight of ammonium bicarbonate, urea, wollastonite, a nitrification inhibitor, humic acid, a water-fixing agent, a bacteriostatic agent, microbial bacteria, a urease inhibitor, trace elements and carboxymethyl chitosan according to the weight ratio of the raw materials;
s2: washing and calcining wollastonite in parts by weight, grinding, and sieving with a 60-100-mesh sieve to obtain wollastonite powder;
s3: adding ammonium bicarbonate, urea and wollastonite powder into a high-speed dispersion machine, adding deionized water at the temperature of 60-80 ℃, and stirring at the rotating speed of 500-800 r/min for 30-50 minutes to obtain a mixture A;
s4: adding a urease inhibitor and carboxymethyl chitosan into the mixture A, and stirring for 1-2h to obtain a mixture B;
s5: adding a nitrification inhibitor, humic acid, a water-fixing agent, a bacteriostatic agent, microbial bacteria and trace elements into the mixture B, and stirring at the temperature of 50-60 ℃ for 50-80 minutes at the rotating speed of 200-500 r/min to obtain a mixture D;
s6: and drying the mixture D until the water content is lower than 3% to obtain the antibacterial microorganism soil conditioner.
