Embodiment 1

[0019] Embodiment 1: The method for reducing the allelopathic effect of notoginseng in this embodiment comprises the following steps:

[0020] Step 1. Leveling the land: After harvesting the last crop of Panax notoginseng, remove the plant residues (stems of Panax notoginseng, fallen leaves) and mulch on the ridge. The soil does not undergo any artificial chemical treatment, and then spread the base fertilizer and lime evenly into the field soil , turn it over with a plow; the base fertilizer (fertilizer is organic fertilizer produced by Kunming Jiuyuan Organic Fertilizer Co., Ltd. Chenggong Branch: total nutrient (N+P 2 o 5 +K) ≥ 5.0%, organic matter ≥ 45%), the addition amount is 1500kg of base fertilizer per mu of soil, and the addition amount of lime is 70kg of lime per mu of soil;

[0021] Step 2, ridge: conventional ridge, ridge length 17m, width 2.0m;

[0022] Step 3, planting and management: transplant the notoginseng seedlings into the ridge, plant 2 rows of celery ...

Abstract

The invention relates to a method for reducing allelopathy effect of Panax notoginseng, belonging to the technical field of planting Chinese medicinal materials. After the last crop of Panax notoginseng is harvested, the soil is leveled without any artificial chemical treatment: before ploughing, a base fertilizer and lime are evenly spread into the field soil and ploughed deeply. Ridging is thenperformed: conventional ridging, 16-17m in length and 1.9-2.0 m in width. Planting and management are performed by transplanting Panax notoginseng seedlings into ridges, planting 1-2 rows of Panax notoginseng every 1-2 rows, laying a mulch layer to form an intercropping system of Panax notoginseng vegetables, and then carrying out routine field management until Panax notoginseng matures. The method utilizes allelochemicals secreted by Panax notoginseng and vegetable roots and allelopathic effects to increase the emergence rate and survival rate of Panax notoginseng, reduce the effect of autotoxicity of Panax notoginseng on the growth and yield of Panax notoginseng, and effectively prevent the economic losses caused by diseases and pests through the intercropping of Panax notoginseng and vegetable.

Description

technical field [0001] The invention relates to a method for reducing the allelopathic effect of notoginseng, which belongs to the technical field of planting Chinese medicinal materials. Background technique [0002] Allelopathy exists widely in nature. It is an adaptive mechanism to the environment produced by organisms in the evolution process, and it is a natural chemical regulation phenomenon in the ecosystem. In the ecosystem, allelopathic effects exist in the germination and suppression of seeds in the process of vegetation formation and succession, intercropping, intercropping, interval residue disposal in agricultural production, and the relationship between crops, weeds, and pests. [0003] The continuous cropping obstacle of Panax notoginseng is a complex ecological environment problem, and allelopathy is an important factor in it. Allelochemical substances can inhibit the germination of Panax notoginseng seeds, reduce the germination rate of Panax notoginseng se...
