Embodiment 1

[0032] A Method for Reducing the Obstacles of Rehmannia Rhizoma Rehmanniae

[0033] 1. Add chicken manure to the anaerobic fermentation tank, and add water at the same time, so that the mass percentage of chicken manure in the mixture of chicken manure and water is 6%, carry out anaerobic fermentation at 30-40°C for 25 days, and collect biogas liquid.

[0034] 2. Select the farmland where rehmannia glutinosa was planted in the previous batch, and pour fresh biogas slurry into the farmland with an irrigation volume of 50m 3 / mu, and ensure that the field is fully wetted until the plow layer is completely wetted, and if it is not completely wetted, continue to irrigate with biogas slurry.

[0035] 3. Cover the wet farmland soil with a transparent plastic film, and seal the surrounding soil to ensure that the outside air is isolated. The film covering time is 30 days, and the ground temperature inside the film during the day is maintained above 40°C.

[0036] 4. Uncover the tran...

Embodiment 2

[0040] A method for reducing obstacles to the cultivation of Rhizoma Rhizoma Rhizoma Rhizoma Rehmanniae, the same steps as in Example 1, except that the biogas slurry used is diluted with 25% water.

Embodiment 3

[0042] A method for reducing obstacles to the cultivation of Rhizoma Rhizoma Rhizoma Rhizoma Rhizoma Rehmanniae, the same steps as in Example 1, except that 50% of water is added to the biogas slurry for dilution.

Abstract

The invention provides a method for reducing successive cropping obstacles of rehmannia glutinosa libosch and application, and belongs to the technical field of agricultural planting. The method for reducing the successive cropping obstacles of the rehmannia glutinosa libosch comprises the following steps: performing anaerobic fermentation on livestock and poultry manure to obtain biogas slurry; irrigating the farmland with the biogas slurry; covering the irrigated farmland with a thin film and conducting cultivation; uncovering the film, and conducting airing; after airing, applying a microbial agent to the farmland; and planting the rehmannia glutinosa libosch by adopting a conventional method. According to the method for reducing the successive cropping obstacles of the rehmannia glutinosa libosch, the survival rate of the rehmannia glutinosa libosch, the biomass of the upper portion and the lower portion of the rehmannia glutinosa libosch and the yield of the rehmannia glutinosa libosch can be remarkably increased, and the successive cropping obstacles of the rehmannia glutinosa libosch can be effectively eliminated.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method and application for reducing the obstacle of rehmannia rhizome cropping. Background technique [0002] Rehmannia glutinosa Libosch is a perennial herb of Scrophulariaceae. It is one of the famous "four medicines for pregnant women" in my country. It has a long history of medication and definite clinical curative effect. [0003] Continuous cropping obstacles refer to the phenomenon that the same crop is continuously planted on the same land for two or more crops, resulting in poor growth, reduced yield, poor quality, and aggravated pests and diseases. According to statistics, about 70% of the root or rhizome medicinal materials have different degrees of continuous cropping obstacles, and some crops such as peanuts, watermelons, cucumbers, and tomatoes also have different degrees of continuous cropping obstacles. The obstacles to cropping Rehman...
