Problems solved by technology

[0004] During the cultivation of crops, various soil-borne diseases such as dead seedlings, rotten roots, green withered, standing withered, yellow wilt, root rot, stem base rot, damping, etc. often plague farmers. The solution is generally to use various The excessive use of pesticides not only makes the soil harden, but also pollutes groundwater resources, resulting in the unsustainable development of agriculture, and the increased drug resistance of disease pathogens has to increase the use of pesticides, resulting in vicious circle
At present, there is no report on compounding Trichoderma harzianum and polyglutamic acid to control the above-mentioned agricultural diseases

Embodiment 1

[0033] Example 1 Experiment of increasing yield of cabbage

[0034] Before planting the cabbage, deep turn the soil, and evenly apply the above-mentioned formulations, apply the same weight of nitrogen fertilizer for the control (CK), and calculate the yield increase rate of the cabbage at harvest;

[0035] Yield increase rate of cabbage%: 100X (treatment per mu yield-control yield per mu) / control yield per mu;

[0036] According to the formula of Colby method (1966), the yield increase rate is calculated and compared with the measured yield increase rate, which is a simple and effective way to evaluate the combined effect of the mixture. The calculation formula is:

[0037] E=X 1 ×X 2 …×X n / 100 (n-1)

[0038] E is the theoretical synergy of the mixed agent; n is the number of mixed agents; X 1 Indicates the increase in yield after the application of the first agent; X 2 Indicates the increase in production rate after applying the second medicament; X n Indicates the increase in yield...

Embodiment 2

[0042] Example 2 Anti-Fusarium Wilt Test

[0043] Select the test field where cotton fusarium wilt often occurs. Before planting the cotton, deep turn the soil and evenly apply the fertilizer with the above content. The control (CK) is the blank control. The cotton grows to 8-9 leaves, and the cotton fusarium wilt is calculated. Incidence rate

[0044] Inhibition rate of cotton fusarium wilt %: 100X (the number of cotton fusarium wilt diseased plants in the control area-the number of cotton fusarium wilt diseased plants in the treatment area) / the number of cotton fusarium wilt diseased plants in the control area;

[0045] According to the Colby method (1966) formula, the inhibition rate is calculated and compared with the measured inhibition rate, which is a simple and effective way to evaluate the combined effect of the mixture. The calculation formula is:

[0046] E=X 1 ×X 2 …×X n / 100 (n-1)

[0047] E is the theoretical inhibition rate of the mixed agent; n is the number of mixed ...

Embodiment 3

[0051] Example 3 Anti-Bacterial Wilt Test

[0052] Select the test field where tomato bacterial wilt often occurs. Before planting tomatoes, turn the land deeply and evenly apply the above-mentioned fertilizer. The control (CK) is the blank control. The tomato grows to 8-9 leaves, and the tomato bacterial wilt is calculated Incidence rate

[0053] Inhibition rate of tomato bacterial wilt %: 100X (number of tomato bacterial wilt diseased plants in the control area-number of tomato bacterial wilt diseased plants in the treatment area) / number of tomato bacterial wilt diseased plants in the control area;

[0054] According to the Colby method (1966) formula, the inhibition rate is calculated and compared with the measured inhibition rate, which is a simple and effective way to evaluate the combined effect of the mixture. The calculation formula is:

[0055] E=X 1 ×X 2 …×X n / 100 (n-1)

[0056] E is the theoretical inhibition rate of the mixed agent; n is the number of mixed agents; X 1 I...

Abstract

The invention discloses a trichoderma harzianum and polyglutamic acid compounded microbial agent and an application thereof. The microbial agent comprises trichoderma harzianum, polyglutamic acid and a pesticide carrier, and the pesticide carrier is selected from a wetting agent, an emulsifier, a dispersant, a stabilizer, a synergist, inorganic filler and organic filler. The composition is compounded from trichoderma harzianum and polyglutamic acid and can improve the soil and improve the crop quality; besides, the microbial agent has a better control effect on pathogenic bacteria of soil-borne diseases, has a remarkable synergistic interaction effect and can control seedling death, root rot, green wilting, dead standing, yellow wilt, butt rot, stalk rot, damping off and other common agricultural diseases.

Description

Technical field [0001] The invention relates to an agricultural inoculum, in particular to an inoculum composed of Trichoderma harzianum and polyglutamic acid and its application. Background technique [0002] Trichoderma can control many plant diseases such as phytophthora, sheath blight and wilt. Trichoderma harzianum is a kind of Trichoderma. As a kind of biocontrol bacteria, it can be used to prevent from Pythium, Rhizoctonia solani, Fusarium, Rhizopus nigricans, Cylindrosporium, Sclerotinia, and Sclerotium Plant diseases caused by pathogenic bacteria. The mechanism of action is high concentration of osmotic pressure, which causes cell dehydration. For example, patent 201510697431.2 discloses a bactericidal composition containing Trichoderma harzianum and metalaxyl; patent 201510810050.0 discloses a nematicidal granule containing abamectin and Trichoderma harzianum; patent 201510697559.9 discloses a kind of Granules of Trichoderma harzianum and Chitooligosaccharides, etc. ...
