Problems solved by technology

[0004] After the applicant's long-term research, it was found that the above-mentioned method for solving continuous cropping obstacles only focused on the soil microbial community structure, and did not start with eliminating harmful root exudates (self-toxic substances). Mainly salicylic acid, 3-phenylpropionic acid, benzoic acid, cinnamic acid and gallic acid

preparation example

[0054] The medium-maturity compost is made by the following methods: screening organic kitchen waste to remove inorganic substances; then separating the screened organic kitchen waste from dryness and wetness to obtain dry matter; The dry matter is mixed with the biological humic acid conversion agent to obtain a mixture; the mixture undergoes a conversion reaction of macromolecular carbon structure degradation under aerobic conditions, the temperature of the conversion reaction is 75° C., and the conversion reaction time is 10 hours to obtain medium-mature compost. Among them, the biological humic acid conversion agent is made by mixing Bacillus subtilis, Sporospora thermophila, Bacillus licheniformis and Bacillus stearothermophilus according to the ratio of viable bacteria number 5.5:5.1:1.5:1.5. The pH of the prepared mid-mature compost is 3.5 to 5.5, and the mid-mature compost contains: organic matter ≥ 60wt%, easily oxidizable organic matter ≥ 20wt%, moisture ≤ 20wt%, and ...

Embodiment 1

[0063] A method for eliminating soil autotoxic substances, comprising the following steps:

[0064] S1. Select 0.1 mu of farmland where ginseng has been planted in the last batch, and pour water into the farmland until the moisture content of the soil is 20% (can be detected by a soil moisture detector);

[0065] S2. Based on the weight of the soil, the weight of the soil is measured by multiplying the area of ​​0.1 mu by the depth of 0.5 m. At least 4 kg of humic acid is added, and a maximum of 16 kg of humic acid is added. As long as the amount of humic acid added makes the pH of the soil within 4.0~5.5 is enough; FeSO 4 The dosage is 0.1mol / kg, Na 2 CO 4 The dosage is 1.0mol / kg, and it is fully mixed with the soil; the reaction time is 3 hours, and the reaction temperature is 20°C;

[0066] S3, then apply mid-ripening compost, the application rate is 20Kg, and the rotary tillage is fully mixed with the soil;

[0067] S4. Cover the wet farmland soil with a black plastic ...

Embodiment 2

[0071] The difference between this embodiment and embodiment 1 is that the application of middle-mature compost is 40Kg.

Abstract

The invention relates to the technical field of soil improvement, and particularly discloses a method for eliminating soil autotoxic substances. The method comprises the following steps that organic acid is added into the soil according to the use amount of the organic acid so that the pH value of the soil is 4.0-5.5; then ferrite and solid peroxide are added into the soil and uniformly mixed with the soil for reaction, and then medium-matured compost is applied into the soil and subjected to rotary tillage into the soil to be fully and uniformly mixed with the soil; the soil is covered with a film for a period of time; and the film is uncovered, and the soil is aired. The method for eliminating the soil autotoxic substances has the advantage of improving soil, capable of being used for reducing the autotoxic substances enriched in the soil due to planting of ginseng, rehmannia, tobacco, pseudo-ginseng and Chinese yam, so that continuous cropping obstacles of crops are eliminated.

Description

technical field [0001] The application relates to the technical field of soil improvement, more specifically, it relates to a method for eliminating soil autotoxic substances. Background technique [0002] With the development of ginseng industry in recent years, the medicinal and economic value of ginseng has aroused widespread concern. However, continuous cropping of ginseng is prohibited, and ginseng can no longer be planted in the field soil where a crop of ginseng has been planted, and ginseng can be planted again after 20-30 years. With the passage of time, the soil available for planting ginseng has decreased year by year, and whether it is forest land or field, the land for ginseng industry is unprecedentedly tight. [0003] At present, there are many studies on continuous cropping obstacles of ginseng at home and abroad, and the main causes of continuous cropping obstacles of ginseng are: ① the number of soil pathogenic microorganisms increases; ② soil physical and...
