Benefits of technology

This patented technology allows for better control over pests by replacing their use with other methods like biological agents or physical means such as soil fences. These new techniques help keep plants healthy from harming crops while reducing environmental impacts associated therewith.

Problems solved by technology

This patented technical problem addressed in this patent relates to improving rice production efficiency during harvesting operations due to factors such as environmental concerns associated with heavy metal contaminants accumulation on corn roots, reduced crop rotation rates leading to overweight grasses, increased costs attributed to land usage, and difficulties controlling root structures within specific areas where they may extend deeper without being affected negatively. Existing methods involve applying multiple applications of nitrification fertilizations alone, but these techniques result in unsatisfactory results because many parameters like moisture content, ammonia concentration, and sulfur deficiency levels affect optimal performance.

Embodiment 1

[0028] The preparation of embodiment 1 microbial bacterial agent

[0029] 1. Screening of functional strains

[0030] (1) Hydrogen oxidizing bacteria

[0031] Hydrogen oxidizing bacteria can use H 2 , with the participation of hydrogenase, CO assimilation 2 and H 2 Synthesize substances and perform chemoautotrophy. In the present invention, measure the H of strain with gas chromatography 2 Absorptive capacity. Purified Xanthobacterium: Xanthobacter autotrophicus, Xanthobacter flavus, Xanthobacter aminoxidans or Xanthobacter tagetidis; Pseudomonas: Phage Pseudomonas hydrogenovora, Rhodopseudomonas palustris; Rhodoparacoccus: Paracoccus sediminis, Paracoccus marcusii connected to R2A slope, etc. After the moss was sealed, the R2A slant inoculated with water was used as a control. Introduce a certain amount of H into the test tube 2 , fully mixed, in order to determine the aforementioned various hydrogen oxidizing bacteria on the H 2 Absorption, in a closed test tube,...

Embodiment 2

[0046] Embodiment 2 The impact of microbial inoculant of the present invention on rice lodging

[0047] 1. Pre-broadcast preparation

[0048] Variety selection: suitable for direct seeding in dry land, choose Longqingdao No. 2 for planting.

[0049] Land selection: flat land, the land should have under-mulch drip irrigation equipment, and the previous crops should not have phytotoxicity.

[0050] Seed fertilizer configuration: pay attention to the supplement of phosphorus and potassium, monoammonium phosphate and potassium chloride (suitable for alkaline soil), and apply farmyard manure together.

[0051] Deep loosening of the soil: Rotary plowing the land twice, after the land preparation, the soil should be crushed and leveled, and the land with phytotoxicity must be plowed in autumn and harrowed in autumn to reduce the phytotoxicity of the previous stubble.

[0052] 2. Sowing

[0053] Seed treatment: Float grains and other debris with salt water, remove the debris, was...

Embodiment 3

[0068] Embodiment 3 The impact of microbial inoculant of the present invention on rice yield

[0069] Plant Longqing Rice No. 2 according to the method of Example 2, observe and record the output of paddy rice, the result is as follows figure 1 , as shown in Table 4 and 5:

[0070] Table 4

[0071] Group (n=20) Thousand grain weight (g) Grains per spike Single panicle weight (g) Effective spike number (10 4 hm -2 )

control group 25.43±1.25 145.18±6.21 3.01±0.21 276.65±5.84 treatment group 29.55±2.33* 177.42±5.11* 3.76±0.85* 291.47±4.23*

[0072] "*" indicates the significance between the treatment group and the control group, P<0.05.

[0073] table 5

[0074]

[0075] As can be seen from Table 4, compared with the control group, the treatment group increased the thousand-grain weight of rice by 8%, the number of grains per panicle by 14%, the number of single panicles by 10%, and the effective panicle number by 2%. This sh...

Abstract

The invention provides a microbial agent. The microbial agent is prepared from the following strain fermentation liquor in parts by weight: 10-50 parts of flavobacterium, 30-60 parts of nitrogen-fixing bacteria and 10-30 parts of zoogloea. The microbial composite inoculant has the advantages that the microbial composite inoculant can replace pesticides to prevent and control soil-borne diseases inthe dry rice growth process and reduce the chemical residues in grains, the toughness and strength of stalk bases can be improved, and the lodging resistance of rice is improved; root system development can be stimulated, root system development is promoted, and root system vitality and ground gripping capacity are improved; automatic nitrogen fixation can be achieved, continuous nitrogen is provided for the whole rice growth period, and abuse of chemical fertilizer is avoided; the yield of drought (water) rice can be increased; and finally, the maturation of dry rice can be advanced by abouttwo weeks, so that the growth period is shortened, and rice enters the market in advance.
