Problems solved by technology

Because the external symptoms of RSD are easily confused with symptoms such as drought and malnutrition, it is easy to cause the disease to spread in the field, and the loss caused by RSD increases with the extension of the perennial root years, which is extremely harmful to sugarcane production and seriously affects sugarcane production.

Embodiment 1

[0024] A preparation method for improving sugarcane anti-perennial root dwarfing organic fertilizer, comprising the steps of:

[0025] (1) Mixed fermentation raw materials: Sprinkle rice bran on corn stalks and mix evenly to obtain fermented raw materials. Among them, each ton of fermentation raw materials consists of 0.8 tons of corn stalks and 0.2 tons of rice bran.

[0026] (2) Making fermentation koji: Paecilomyces lilacinus (Thorn.) Samson, No. ACCC11103), yeast (Bacillus saccharomyces, No. ACCC30620) and Trichoderma spp. (No. ACCC30169) were selected as fermentation Bacterial classification, these three kinds of bacterial classifications are all purchased from National Culture Collection Center, and the mass percentages of the three are respectively: Paecilomyces lilacinus 33%, saccharomyces 33% and Trichoderma virides 34%, that is, the mass percentages of the three The sum is 100%.

[0027] Operate under sterile conditions, purify the strains of Paecilomyces lilacinus...

Embodiment 2

[0035] An organic fertilizer for improving sugarcane resistance to perennial root dwarf disease and its fermented koji, comprising the following preparation steps:

[0036] (1) Mixed fermentation raw materials: Sprinkle rice bran on rice straw and mix evenly. Among them, each ton of fermentation raw material consists of 0.85 tons of rice straw and 0.15 tons of rice bran.

Abstract

The invention belongs to the technical field of fertilizers, and particularly relates to an organic fertilizer for improving ratoon stunting disease resistance of sugarcane and a preparation method ofthe organic fertilizer. According to the organic fertilizer for improving the ratoon stunting disease resistance of the sugarcane, fermentation raw materials of the organic fertilizer comprise crop straw and rice bran, and zymophyte koji of the organic fertilizer is composed of paecilomyces lilacinus, saccharomycetes and trichoderma viride; 2-5 kg of the zymophyte koji is prepared for each ton ofcrop straw. The paecilomyces lilacinus, the saccharomycetes and the trichoderma viride are mixed to prepare the zymophyte koji, and the rice bran is added into the fermented crop straw, so that the prepared organic fertilizer improves the soil fertility, well prevents and treats the ratoon stunting disease of the sugarcane, solves the continuous cropping obstacle of the sugarcane, and ensures thesustainability of sugarcane production.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to an organic fertilizer for improving sugarcane resistance to perennial root dwarf disease and a preparation method thereof. Background technique [0002] Sugarcane ratoon stunting disease (RSD) is a worldwide disease that is widespread in sugarcane areas. Under drought conditions, the yield loss of ratoon cane of some susceptible varieties can reach more than 50%. It was first discovered in sugarcane variety Q28 in Queensland, Australia in 1944-1945. The pathogen of sugarcane perennial root dwarf disease is Leifsoniaxyli subsp.xyli (Lxx), which parasitizes in the xylem vessels of sugarcane plants and can infect all known species of Saccharum, but not other plants. The pathogenic bacteria of Lxx are extremely small, and it is extremely difficult to isolate, cultivate and detect them, which brings great difficulties to the research. After sugarcane is infected with ratoon dwa...
