Problems solved by technology

Especially when the rainy season comes every year, continuous rainfall will lead to serious water accumulation in the ridges and ditches of the Panax notoginseng planting area, which will make the soil permeability of the Panax notoginseng root zone worse, resulting in a high incidence of root rot
At present, the common practice adopted by Panax notoginseng growers is to increase the spraying amount and frequency of pesticides to suppress the high incidence of root diseases. Excessive application of pesticides will easily cause environmental pollution and excessive pesticide residues.
In addition, the current research on the water demand law of Panax notoginseng, the physiological characteristics of water and the influence of soil moisture content on the physiological characteristics, yield and incidence of major diseases of Panax notoginseng are still relatively weak. The research on pipe drainage method is almost blank

Embodiment 1

[0027] Embodiment 1: the present embodiment notoginseng is specially used to improve the underground pipe drainage method, which comprises the following steps:

[0028] Step 1. Leveling the land: Spread the base fertilizer and lime evenly into the field soil before plowing, and turn it over deeply 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;

[0029] Step 2. Laying the underground drainage pipe: Before ridge formation, lay a PVC plastic corrugated pipe with a length of 2.0m and a pipe diameter of 32mm at a depth of 50cm from the surface of each ridge. The opening rate of the corrugated pipe is 15%. Wrapped with a layer of nylon net to prevent the soil from blocking the drainage pipe, the dista...

Embodiment 2

[0033] Embodiment 2: the present embodiment notoginseng special improvement underground pipe drainage method, it comprises the following steps:

[0034] Step 1. Leveling the land: Spread the base fertilizer and lime evenly into the field soil before plowing, and turn it over deeply 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 1000kg of base fertilizer per mu of soil, and the addition amount of lime is 50kg of lime per mu of soil;

[0035] Step 2. Laying the underground drainage pipe: lay a PVC plastic corrugated pipe with a length of 1.9m and a pipe diameter of 30mm at a depth of 30cm from the surface of each ridge before ridging. The opening rate of the corrugated pipe is 10%. A layer of nylon mesh is wrapped to prevent the soil from blocking the drainage pipe. The distance between the corrugated...

Embodiment 3

[0040] The notoginseng-specific method for improving the drainage of hidden pipes comprises the following steps:

[0041] Step 1. Leveling the land: Spread the base fertilizer and lime evenly into the field soil before plowing, and turn it over deeply 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 1200kg of base fertilizer per mu of soil, and the addition amount of lime is 60kg of lime per mu of soil;

[0042] Step 2. Laying the underground drainage pipe: lay a PVC plastic corrugated pipe with a length of 2.0m and a pipe diameter of 25mm at a depth of 40cm from the surface of each ridge before ridging. The opening rate of the corrugated pipe is 12%. Wrapped with a layer of nylon mesh to prevent the soil from clogging the drainage pipe. The distance between the corrugated pipes is 80cm. After the hid...

Abstract

The invention relates to a special improved concealed pipe drainage method for panax notoginseng, and belongs to the technical field of traditional Chinese medicine material planting. The method comprises the following steps: leveling land: evenly scattering a base fertilizer and lime into field soil before ploughing, and carrying out deep plouging once by using a plough; laying drainage concealedpipes: laying drainage concealed pipes which are provided with holes in advance at a place with a depth of 30-50 cm away from the ground surface in each ridge before ridging, wherein the hole openingrate is 10-15%, the pipe diameter ranges is 25-32 mm, and the pipe laying spacing is 60-100 cm; carrying out ridging: carrying out conventional ridging, wherein the ridge length is 16-17 m, and the width is 1.9-2.0 m; and carrying out planting and managing: transplanting panax notoginseng seedlings into the ridges and laying a covering layer, and then carrying out daily conventional field management until the panax notoginseng is mature. According to the method disclosed by the invention, the discharge speed of soil moisture is accelerated by laying the improved concealed pipes, the problem that the water content of the soil in panax notoginseng root areas is too high due to water accumulation of panax notoginseng ridges in rainy seasons is prevented, then root rot of panax notoginseng root systems is avoided, and influence to normal growth of panax notoginseng can be avoided. Accumulated water can be quickly drained, and meanwhile air permeability and water permeability of soil can be enhanced, so that production cost of panax notoginseng is reduced, and the method can be better applied to the field of traditional Chinese medicine material planting.

Description

technical field [0001] The invention relates to an improved underground pipe drainage method specially used for Panax notoginseng, which belongs to the technical field of planting Chinese herbal medicines. Background technique [0002] Panax notoginseng (Burk.) F.H.Chen is a perennial herb. It is the main raw material of large varieties of Chinese patent medicines such as Yunnan Baiyao, Compound Danshen Dripping Pills, Pien Tze Huang, and Xuesai Tong. Pillar industries play an important role in promoting the economic and social development of the region. [0003] Water is the cradle of life, and all life activities of plants must be completed under the condition of sufficient water in the cells. Most of the water in plants is absorbed in the soil through plant roots, and the state of soil water directly affects the water state of plants. Too little water will change the structure and permeability of the membrane, destroy the normal metabolic process and mechanical damage; ...
