Embodiment 1

[0044] The preparation of embodiment 1 microbial bacterial agent

[0045] 1. Screening of functional strains

[0046] (1) Hydrogen oxidizing bacteria

[0047] 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 Hydrogenophaga: Hydrogenophaga atypica, Hydrogenophaga palleronii, Hydrogenophaga flava; Pseudomonas: Pseudomonas Pseudomonas hydrogenovora, Rhodopseudomonas palustris; Rhodoparacoccus: Paracoccus sediminis and Paracoccus marcusii are inserted into the slope of R2A, and sealed after the bacterial lawn is present. 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 te...

Embodiment 2

[0064] Embodiment 2 measures the survival situation of bacteria in the microbial inoculum of the present invention

[0065] Soil conditions: pH7.55, ammonia nitrogen concentration 6.18mg / kg, nitrate nitrogen concentration 25.51mg / kg;

[0066] Seed soaking treatment: wheat Zhengmai 7698 was soaked in the microbial agent of Example 1 for four hours;

[0067] Spraying treatment: the leaves are sprayed every 6 weeks, and the spraying agent is the bacterial agent prepared in Example 1.

[0068] The specific operation method is as follows:

[0069] The soil from Xiping County, Henan Province was used to carry out a wheat pot experiment to determine the effect of the microbial agent of the present invention. Take by weighing 2 kg of soil in every pot, keep sufficient moisture in the pot, do not apply base fertilizer for potted plants, and do not use chemical drugs, directly sow three seeds of wheat Zhengmai 7698 per pot as a contrast, and soak the wheat seeds for four weeks in th...

Embodiment 3

[0073] Embodiment 3 The effect of bacterial agent of the present invention on the late-maturing phenomenon

[0074] The Zhengmai 7698 demonstration field was divided into a control group and an experimental group.

[0075] Control group 1: Wheat was sown in Yuange Village, Gaosi Town, Henan Province on October 11, 2019 by conventional methods. The basic properties of the soil were: pH 7.55, ammoniacal nitrogen concentration 6.18mg / kg, and nitrate nitrogen concentration 25.51mg / kg, apply compound fertilizer 64 kg per mu.

[0076] Control group 2: adopt the same method as control 1, the only difference is that compared with control group 1, the use of compound fertilizer is reduced, and the compound fertilizer is applied at 32 kg per mu.

[0077] Treatment group: sowed on October 11, 2019 in Yuange Village, Gaosi Town, Henan Province, soaked the winter wheat seeds with the bacterial agent of Example 1 for four hours before sowing, and then dried them on October 11, and appli...

Abstract

The invention provides a microbial agent. The microbial agent comprises the following components in parts by weight: 20 to 60 parts of hydrogen-oxidizing bacteria, 20 to 60 parts of nitrogen-fixing bacteria, 30 to 50 parts of actinomycetes and 30 to 60 parts of fungi, wherein the actinomycetes can be actinoplanes, streptomycetes or nocardia; and the fungi can be pythium or trichoderma. The microbial agent disclosed by the invention generates a certain synergistic effect through the combination of the hydrogen-oxidizing bacteria, the nitrogen-fixing bacteria, the actinomycetes and the fungi, and can improve the yield of wheat, promote the development of wheat root systems and improve the good earth holding capacity of roots for soil, so that main roots, side roots and fibrous roots are deeper and wider in coverage and are difficult to lodge and stronger in water absorption, eustipes close to the ground has better toughness and strength, the toughness and strength of the stems can be improved, and the stems are difficult to break. The microbial agent provided by the invention can shorten the growth and maturation time, enable crops to be matured in advance, reduce the risks of vigorous growth of seedlings and green remaining and late maturation of plants, and promote early fruiting and maturation of the plants to appear in the market.

Description

technical field [0001] The invention belongs to the technical field of agricultural microorganisms, and in particular relates to a microbial agent for wheat planting. Background technique [0002] Due to the long-term excessive use of chemical fertilizers in my country's agriculture, it will lead to the lack of organic matter, the loss of beneficial microorganisms in the soil, and the incidence and frequency of pests and diseases will increase. Farmers rely more on pesticides to control pests and diseases, which will further reduce the quality of agricultural products. This has caused a series of problems. According to the analysis of academician Zhu Zhaoliang of the Soil Research Institute of the Chinese Academy of Sciences, the use of chemical fertilizers in my country has increased significantly to 55 times in the past 40 years. From 1980 to 2002, my country's grain output increased by 31%, while my country's chemical fertilizer use increased by 61%. The fertilizer in far...
