Embodiment 1

[0026] The raw material of the foliar fertilizer of the present embodiment is composed of 20 parts by weight of composite microorganisms, 20 parts of potassium dihydrogen phosphate, 10 parts of urea, 20 parts of calcium dihydrogen phosphate, 20 parts of allicin and 10 parts of Glauber's salt.

[0027] The composite microorganism is composed of Trichoderma harzianum powder, Trichoderma longibranchus powder, Streptomyces coccidioides powder and Bacillus subtilis powder. The mass fractions of the four single-strain powders are: Trichoderma harzianum powder 25%, Trichoderma longibrachiae powder 30%, Streptomyces coccidioides powder 25% and Bacillus subtilis powder 20%. The inventor prepared four kinds of single-strain bacterial powders by himself. On the one hand, Trichoderma harzianum and Trichoderma longibrachiae are firstly prepared into liquid seed liquids, and then the seed liquids are inoculated in corresponding solid-state culture medium, and fermented to obtain solid-state...

Embodiment 2

[0033] The raw material of the foliage fertilizer of the present embodiment consists of 23 parts by weight of composite microorganisms, 16 parts of potassium dihydrogen phosphate, 13 parts of urea, 17 parts of calcium dihydrogen phosphate, 16 parts of allicin and 20 parts of mirabilite.

[0034] The composite microorganism is composed of Trichoderma harzianum powder, Trichoderma longibranchus powder, Streptomyces coccidioides powder and Bacillus subtilis powder. The mass fractions of the four single-strain powders are: Trichoderma harzianum powder 32%, 21% Trichoderma longibrachiae powder, 17% Streptomyces coccidioides powder and 30% Bacillus subtilis powder. The inventor prepared four kinds of single-strain bacterial powders according to the method of Example 1. The bacterial content of Trichoderma harzianum ≥ 1.5×10 10 cfu / g, the bacterial content of Trichoderma longibrachiata ≥ 2.0×10 10 cfu / g, the bacterial content of Streptomyces coccidioides ≥3.5×10 9 cfu / g, the bacte...

Embodiment 3

[0038] The raw material of the foliar fertilizer of the present embodiment is composed of 27 parts by weight of composite microorganisms, 13 parts of potassium dihydrogen phosphate, 17 parts of urea, 14 parts of calcium dihydrogen phosphate, 13 parts of allicin and 30 parts of Glauber's salt.

[0039]The composite microorganism is composed of Trichoderma harzianum powder, Trichoderma longibranchus powder, Streptomyces coccidioides powder and Bacillus subtilis powder. The mass fractions of the four single-strain powders are: Trichoderma harzianum powder 37%, Trichoderma longibrachiae powder 25%, Streptomyces coccidioides powder 13% and Bacillus subtilis powder 25%. The inventor prepared four kinds of single-strain bacterial powders according to the method of Example 1. The bacterial content of Trichoderma harzianum ≥ 1.5×10 10 cfu / g, the bacterial content of Trichoderma longibrachiata ≥ 2.0×10 10 cfu / g, the bacterial content of Streptomyces coccidioides ≥3.5×10 9 cfu / g, the ...

Abstract

The invention discloses a foliar fertilizer for preventing and controlling potato fusarium diseases and application thereof. The foliar fertilizer is prepared from the following raw materials: compound microorganisms, monopotassium phosphate, urea, monocalcium phosphate, allicin and mirabilite. The fertilizer is prepared from the following raw material components in parts by weight: 20-30 parts of compound microorganisms, 10-20 parts of monopotassium phosphate, 10-20 parts of urea, 10-20 parts of monocalcium phosphate, 10-20 parts of allicin and 10-40 parts of mirabilite. In the planting process of potatoes, a period with exuberant dew is selected, firstly, leaf fertilizer is diluted with water, and then the diluted leaf fertilizer is evenly sprayed to the leaf surfaces of potato plants. The foliar fertilizer is used for planting potatoes and can prevent and control the fusarium disease of the potatoes, promote the growth of the potatoes and increase the yield of the potatoes.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to a foliar fertilizer for preventing and controlling potato Fusarium disease and its application. Background technique [0002] Potato is the fourth largest food crop in the world, and it is also an important vegetable, which plays an important role in my country's food production and people's daily life. As people's consumption demand for potatoes increases day by day, the planting area and output of potatoes in our country increase year by year. [0003] Fusarium is a major plant pathogen, which can cause dry rot and wilt of potatoes. The occurrence of potato Fusarium disease will lead to wilting of plants, dead leaves, and serious decline in the yield and quality of potato cubes, which will cause serious damage to potato production. damage. [0004] Therefore, for the Fusarium disease of potato, it is of great significance to develop a foliar fertilizer conta...
