example 1

[0058] Example 1. The waste molasses from a certain factory in Yunnan was dried to obtain molasses powder with a moisture content of less than 12%, which was packaged in packaging bags. Contrast experiment with the same liquid molasses for disinfection of diseased soil with continuous cropping obstacles. The moisture content of molasses liquid is 55%, which is a viscous liquid. In the past, it was packaged in plastic jars and used in large quantities as the main material of the RSD method. The comparative test situation of this example is as follows:

[0059] The source of the diseased soil: Acacia plum cultivation base of a cooperative in Jinning, Yunnan, continuous cropping of the diseased soil, the number of Fusarium oxysporum in the soil was 4.07×10 7 ITS copies g -1 dry soil.

[0060] Treatment settings: including four treatments: 0.046% molasses powder (equivalent to 120kg / mu); 0.063% molasses powder (160kg / mu); 0.077% (200 kg / mu); 0.15% liquid molasses (400 kg / mu). ...

example 2

[0069] Example 2. The waste molasses from a sugar factory in Yunnan was dried to obtain molasses powder, with a water content of 12%, which was specially ordered by a friend and packed in plastic bags. Contrast experiment with the same liquid molasses for disinfection of diseased soil with continuous cropping obstacles. The moisture content of molasses liquid is 52%, which is a viscous liquid. In the past, it was packaged in plastic jars and used as the main raw material of RSD method in large quantities.

[0070] The comparative test situation of this example is as follows:

[0071] The source of the diseased soil: the chili cultivation base of a company in Changshu City, continuous cropping of 5 diseased soils, the number of Fusarium oxysporum in the soil was 4.76×10 6 ITS copies g -1 dry soil.

[0072] Treatment settings: 0.069% molasses powder (equivalent to 180kg / mu); 0.096% molasses powder (250kg / mu); 0.15% liquid molasses (400kg / mu). One mu of land is calculated as...

example 3

[0082] Example 3. Using commercially available brown sugar (the lowest grade sugar), after powdering, the diseased soil of Tuanjie Township, Kunming, Yunnan, which has been planted with lilies for many years, was treated with RSD, and compared with other treatments. Including control original disease soil, liquid molasses treatment, material treatment and brown sugar powder treatment.

[0083] Detection indicators: pH, EC, the number of Fusarium oxysporum.

[0084] The detection method is the same as Example 1.

[0085] Test results:

[0086] After the RSD treatment, the soil pH was all acidic. Compared with the contrast, the pH values ​​after the treatment were all significantly increased, and there were significant differences among different treatments. Among them, the pH value of the material treatment was as high as 5.8, liquid molasses 5.5, brown sugar powder 4.9, and the control ( Original diseased soil) 4.8.

[0087] EC value, after RSD treatment, the reduction of m...

Abstract

The invention relates to soil continuous cropping disorder soil disinfection water-soluble powder and application thereof. One or more of molasses powder, brown sugar, white sugar, brown granulated sugar, brown granulated sugar and potassium fulvic acid is obtained by drying and pulverizing liquid molasses; the water content of the molasses powder is less than 12 percent; the liquid molasses is abyproduct or production waste of a sugar refinery and the water content is more than 40 percent; the brown sugar, the white sugar, the brown granulated sugar, the brown granulated sugar and the potassium fulvic acid are powder or granules; and the material is powder when being used in a solid form, and the material is powder, granule or block mass when being dissolved into water to use. The use method is conducted in two modes of facility agriculture and non-facility agriculture; the facility agriculture is to dissolve water-soluble powder into water, water in sick soil, cover with a membraneto isolate the air and perform anaerobic RSD treatment; and the non-facility agriculture is to water half of water to wet the sick soil, scatter the water-soluble powder on the surface of the sick soil, water, cover with a membrane to isolate the air and perform anaerobic RSD treatment. When the sick soil is treated by combining the common water-soluble powder materials with an RSD method, fusarium oxysporum can be killed efficiently and continuous cropping obstacles can be eliminated.

Description

technical field [0001] The invention relates to soil biotechnology, in particular to a water-soluble powder for disinfection of diseased soil with continuous cropping obstacles and its application. Background technique [0002] The obstacle of continuous cropping is the phenomenon that in the process of agricultural production, the same crop is planted for many years, and the crop yield and quality decrease year by year. The research of modern scientific and technological means shows that the root cause of continuous cropping obstacles is the massive reproduction of soil-borne pathogenic bacteria and root-knot nematodes, which lead to the increase of soil-borne diseases, infecting crops and causing different degrees of mortality, soil acidification, secondary salinization, and imbalance of nutrient supply , the accumulation of allelochemical substances leads to stunted crop growth. [0003] The existing technical means to eliminate continuous cropping obstacles generally in...
