specific Embodiment 1

[0020] A soilless cultivation method for Panax notoginseng seedlings, comprising the following steps: a. Using peat, bagasse decomposed matter, perlite, vermiculite, mushroom dregs and coconut bran by volume 4:2:1:1:1:1 The ratio is mixed into a soilless cultivation substrate; b. The soilless cultivation substrate is stacked and leveled in the greenhouse to form a planting field with a uniform thickness of 14 to 17 cm; c. The seeds of Panax notoginseng are planted in the planting field filled with the soilless cultivation substrate, Plant 400 plants per square meter; d. Control the air humidity in the greenhouse between 70% and 80%, and control the humidity of the soilless culture substrate between 25% and 30%, and then adjust the greenhouse according to the different growth stages of Panax notoginseng The temperature and light transmittance in the greenhouse are controlled at 10-14 degrees Celsius, 14-17 degrees Celsius, 18 Between ~24 degrees Celsius and 14~19 degrees Celsiu...

specific Embodiment 2

[0023] This embodiment is based on specific example 1, and the fertilization in step e is described in detail. In the above step e, fertilization is carried out by flushing fertilization during the leaf spreading stage of Panax notoginseng, and the application amount of water-soluble chemical fertilizer is 7~ 8.5kg / mu, add water-soluble chemical fertilizers to water 1000 times its mass for deployment before spreading. The mass ratio of nitrogen, phosphorus, and potassium elements in water-soluble chemical fertilizers is 3:1:2. During the growth stage of notoginseng In the mid-term, fertilization is carried out by flushing fertilization. The amount of water-soluble chemical fertilizers is 7-8.5kg / mu. Water-soluble chemical fertilizers are added to water 1000 times its mass for deployment before spreading. The nitrogen, phosphorus, and potassium elements in water-soluble chemical fertilizers The mass ratio of Panax notoginseng is 1:1:2. Fertilization is carried out in the later s...

specific Embodiment 3

[0026] This example is based on specific example 1 to describe the peat in the above step a in detail, the peat in the above step a is low-level peat with humic acid content between 15% and 20%. Because Panax notoginseng usually grows in a weakly acidic environment, the content of humic acid in peat should not be too high. It is most suitable to use peat with a humic acid content of 15% to 20% to adjust the pH of the substrate. At the same time, low-level peat is rich in Inorganic salts such as potassium, sodium, magnesium, etc., compared with the soilless culture substrate prepared without peat with a humic acid content of 15% to 20%, the low peat with a humic acid content of 15% to 20% was used in the experiment. Prepare the soilless cultivation medium, and under the same conditions of other external adjustments, the seedling survival rate of Panax notoginseng is 15% to 35% higher.

Abstract

The invention discloses a soilless cultivation method of panax notoginseng seedlings. The method comprises the following steps that 1, peat, bagasse decomposing products, perlite, vermiculite, mushroom residues and coconut coir are mixed into a soilless medium according to the volume ratio of 4:2:1:1:1:1; 2, the soilless cultivation medium is stacked and leveled into a planting field with the uniform thickness of 14-17 cm in a greenhouse; 3, panax nogoginseng seeds are seeded into the planting field filled with the soilless cultivation medium; 4, the temperature, air humidity, medium humidity and light transmittance in the greenhouse are controlled according to growth of panax notoginseng; 5, fertilizing is conducted in the leaf expansion period, growth stage middle period and growth stage later period of the panax notoginseng; 6, after a first round of panax notoginseng is planted, the medium is put into a water flooding pool to be soaked, and desalting treatment and detoxifying treatment are conducted; 7, after soaking is completed, a second round of planting starts to be conducted. Accordingly, the problems that in the prior art, the panax notoginseng cannot be cultivated in a soilless mode or continuously planted are solved.

Description

technical field [0001] The invention relates to the field of soilless cultivation, in particular to a method for soilless cultivation of notoginseng seedlings. Background technique [0002] Panax notoginseng, also known as Tianqi, is a precious traditional Chinese medicine. It belongs to dicotyledonous plants. It is very picky about the growth environment. It usually grows in areas with an altitude of 1000-1500m. The main production area is Wenshan Prefecture, Yunnan. It can be used as medicine. It is sweet and slightly bitter. It is a warm medicinal material. It has the effects of dispelling blood stasis, hemostasis, reducing swelling and relieving pain. Taking an appropriate amount of Panax notoginseng powder can also soften blood vessels, promote blood health, and prevent cardiovascular diseases. [0003] With the improvement of people's lives, people pay more and more attention to their own health. Although Western medicine can quickly treat most of the ailments, the sid...
