Problems solved by technology

are not conducive to the stable absorption of plants
[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
Adopt Trichoderma harzianum and silicon fertilizer to prevent and control the above-mentioned agricultural diseases, there is no report yet

Embodiment 1

[0032] Example 1 Maize yield increase experiment

[0033] Before corn planting, the land was deeply plowed, and the preparation of the above content was uniformly applied, and the same weight of nitrogen fertilizer was applied to the control (CK), and the yield increase rate of corn was calculated when harvesting;

[0034] Maize yield increase %: 100X (treatment mu yield-contrast mu yield) / contrast mu yield;

[0035] According to the formula of Colby's method (1966), the yield increase rate was calculated and compared with the measured yield increase rate, so as to evaluate the joint effect of the mixture simply and effectively. The calculation formula is:

[0036] E=X 1 ×X 2 …×X n / 100 (n-1)

[0037] E is the theoretical synergy of the mixture; n is the quantity of the mixture; X 1 Indicates the yield increase rate after the application of the first drug; X 2 Indicates the yield increase rate after the application of the second chemical agent; X n Indicates the yiel...

Embodiment 2

[0041] Example 2 Tomato Yield Increase Experiment

[0042] Before tomato planting, the land was deeply plowed, and the above-mentioned preparation was uniformly applied, and the same weight of nitrogen fertilizer was applied to the control (CK), and the tomato yield increase rate was calculated when harvesting;

[0043] Tomato yield increase %: 100X (treatment mu yield-contrast mu yield) / contrast mu yield;

[0044] According to the formula of Colby's method (1966), the yield increase rate was calculated and compared with the measured yield increase rate, so as to evaluate the joint effect of the mixture simply and effectively. The calculation formula is:

[0045] E=X 1 ×X 2 …×X n / 100 (n-1)

[0046] E is the theoretical synergy of the mixture; n is the quantity of the mixture; X 1 Indicates the yield increase rate after the application of the first drug; X 2 Indicates the yield increase rate after the application of the second chemical agent; X n Indicates the yield...

Embodiment 3

[0050] Embodiment 3 anti-dead vaccine experiment

[0051] Select the experimental field where the dead seedling disease of pepper often occurs. Before the pepper is planted, the land is deeply plowed, and the above-mentioned fertilizer is evenly applied. The control (CK) is a blank control. The pepper grows to 8-9 leaves, and the dead seedling disease of pepper is calculated. incidence rate;

[0052]Capsicum dead seedling disease inhibition rate%: 100X (control area capsicum dead seedling disease diseased strain number-treatment area capsicum dead seedling disease diseased strain number) / control area capsicum dead seedling disease diseased strain number;

[0053] According to the formula of Colby's method (1966), the inhibition rate was calculated and compared with the measured inhibition rate, so as to evaluate the joint effect of the mixture simply and effectively. The calculation formula is:

[0054] E=X 1 ×X 2 …×X n / 100 (n-1)

[0055] E is the theoretical inhibit...

Abstract

The invention discloses a Trichoderma harzianum and silicon fertilizer compounded fungicide and an application thereof. The fungicide is composed of Trichoderma harzianum, a silicon fertilizer and a pesticide carrier. The pesticide carrier is selected from an emulsifier, an excipient, a thickener, a fungus keeping agent, a dispersant and an organic filler. The composition can increase the output of crops, improve soil and improve the quality of the crops, has a good prevention and control effect on pathogens of soil borne diseases, has an obvious synergistic effect, and can prevent and control dead seedlings, rotten roots, green wilting, dead standing, yellow wilt, foot root, damping-off and other agricultural common diseases of the crops.

Description

technical field [0001] The invention relates to an agricultural fungus, in particular to a compounded fungus of Trichoderma harzianum and silicon fertilizer and its application. Background technique [0002] Trichoderma can control various plant diseases such as Phytophthora, Sheath Blight, and Drip Blight. Trichoderma harzianum is a kind of Trichoderma, as a biocontrol fungus, it can be used to prevent Pythium, Rhizoctonia solani, Fusarium, Rhizopus niger, Cylindrosporium, Sclerotinia, Sclerotinia Plant diseases caused by pathogenic bacteria. The mechanism of action is high concentration osmotic pressure, which leads to dehydration of cells. [0003] Silicon fertilizer is a kind of medium element fertilizer. Silicon fertilizer can be used not only as fertilizer to provide nutrients, but also as a soil conditioner to improve soil. In addition, it also has the functions of disease prevention, insect prevention and poison attenuation. With its outstanding advantages such ...
