specific Embodiment approach 1

[0019] Specific embodiment one: present embodiment is a kind of method for planting perennial root Chinese herbal medicine on severe saline-alkali land, specifically carry out according to the following steps:

[0020] 1. Apply the aeolian soil within 1000 meters near the severe saline-alkali land to the surface of the saline-alkali land, and the thickness of the sand covering is 30cm-40cm;

[0021] 2. Use a plow to open multiple ditches in parallel in the heavily saline-alkali land covered with sand. The horizontal width of the ditch is 25 cm, and the depth of the ditch is 10 cm to 15 cm;

[0022] 3. Cut the main root of the Chinese herbal medicine seedling to 20cm~40cm as the root of transplanting, and place the cut main root horizontally in the ditch opened in step 2 (the main root is completely in the sandy soil and does not enter the saline-alkali soil). The above-ground part is exposed on the surface of wind-sand soil;

[0023] 4. Close up the sandy soil on the ditch so...

specific Embodiment approach 2

[0025] Embodiment 2: This embodiment differs from Embodiment 1 in that: the Chinese herbal medicine seedlings described in step 3 are licorice seedlings. Others are the same as the first embodiment.

specific Embodiment approach 3

[0026] Embodiment 3: This embodiment is different from Embodiment 1 or 2 in that: the Chinese herbal medicine seedlings described in step 3 are windproof seedlings. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a method for planting Chinese herbal medicine for rooting for many years on severe saline-alkali soil, and relates to a method for planting Chinese herbal medicine on saline-alkali soil. The invention aims to solve the technical problems of difficult seed germination, slow seedling development and reduced root activity caused by severe saline-alkali stress on severe saline-alkali soil of traditional Chinese herbal medicines for rooting for many years at present. According to the Chinese herbal medicine lateral root vertical growth characteristic and the asexual propagation characteristic, the severe saline-alkali soil is improved through aeolian sandy soil, and the method is suitable for large-area Chinese herbal medicine planting popularization; on one hand, the requirement for the sand covering thickness is effectively lowered, on the other hand, the problem that Chinese herbal medicine main roots take too deep roots and cannot survive in the saline-alkali soil layer is solved, the main roots are horizontally planted, Chinese herbal medicine root systems can be conveniently obtained and utilized, disturbance to the deep soil layer is lowered, and the problem that a large number of saline-alkali ions rise is solved. According to the biological principle, saline-alkali ions are prevented from moving to surface soil, the cost is low, popularization is easy, and later economic benefits are achieved.

Description

technical field [0001] The invention relates to a method for planting Chinese herbal medicine on saline-alkali ground. Background technique [0002] Glycyrrhiza uralensis, Saposhnikovia divaricata, Bupleurum scorzonerifolium, Scutellaria baicalensis, and Astragalus propinquus belong to perennial plants, which are distributed in Northeast my country and North China. The roots or The rhizome can be used as medicine, which has the effects of clearing away heat and detoxifying, moistening the lungs and relieving cough. There are many studies on the nutritional components and medicinal mechanisms of these perennial Chinese herbal medicines. Due to the increasing market demand for licorice and other Chinese herbal medicines whose roots are harvested, the resources of these wild Chinese herbal medicines have been seriously depleted. Resources have been protected, artificial planting of Chinese herbal medicine and other industries have gradually become standardized and industrializ...
