Problems solved by technology

People can obtain a small amount of kudzu resources through field digging, but with the increase in market demand and the continuous reduction of wild kudzu resources, field digging can no longer meet people's demand for it
In addition, if the annual young Pueraria lobata is used for propagation, the labor cost will be increased, and the cut young Pueraria lobata may have rotten roots due to some mechanical damage, which will greatly reduce the yield and quality of Pueraria lobata.

Embodiment 1

[0028] A method for efficiently cultivating kudzu seedlings, comprising the following steps:

[0029] 1. Material collection: Select the kudzu vine mother plant that is more than 2 years old, take the tender stems that are 1-2 years old as cutting seedlings, cut the internodes into small sections, keep 2cm long on the small section, keep 6cm long under the section, and Cut at a 40-degree angle.

[0030] 2. Soaking: Soak the clipped seedlings in soaking solution A for 3 hours, take them out, and place them in an environment of 15-20°C for 2 hours, then soak the seedlings in soaking solution B for 3 hours, take them out, and place them at 15-20°C for 2 hours. Place at 20°C for 3 hours. Wherein the soaking solution A is: 12 parts of sodium chloride, 10 parts of vitamin B, 12 parts of vitamin C, 6 parts of copper sulfate, 6 parts of slaked lime, 15 parts of formalin, 410 parts of purified water; soaking solution B is: potassium nitrate 20 parts, calcium nitrate 15 parts, urea 18...

Embodiment 2

[0034] A method for efficiently cultivating kudzu seedlings, comprising the following steps:

[0035] 1. Material selection: Select the kudzu vine mother plant that is more than 2 years old, take the tender stems that are 1-2 years old on it as cutting seedlings, cut the internodes into small sections, keep 1.5cm long on the small section, and keep 6cm long for the cutting part below the node. And cut into a 30-degree angle slope.

[0036] 2. Soaking: Soak the clipped seedlings in soaking solution A for 2.5 hours, take them out, and place them in an environment of 15-20°C for 1.5 hours, then soak the seedlings in soaking solution B for 4 hours, take them out, and place them at 15-20°C for 1.5 hours. Place in a 20°C environment for 2.5 hours. Wherein the soaking liquid A is: 16 parts of sodium chloride, 15 parts of vitamin B, 16 parts of vitamin C, 5 parts of copper sulfate, 5 parts of slaked lime, 20 parts of formalin, 430 parts of purified water; soaking liquid B is: potassi...

Embodiment 3

[0040] A method for efficiently cultivating kudzu seedlings, comprising the following steps:

[0041] 1. Material selection: Select the mother plant of kudzu vine over 2 years old, take the tender stems 1-2 years old on it as cutting seedlings, cut the internodes into small sections, keep 2cm long on the small section, keep 7cm long under the section, and Cut at a 45-degree angle.

[0042] 2. Soaking: Soak the clipped seedlings in soaking solution A for 3.5 hours, take them out, and place them in an environment of 15-20°C for 2.5 hours, then soak the seedlings in soaking solution B for 3 hours, take them out, and place them at 15-20°C for 2.5 hours.

Abstract

The invention discloses an efficient culturing method of pueraria lobata seedlings. A biennial or older kudzu vine mother plant is selected, an annual or biennial spear of the kudzu vine mother plantis taken as a cuttage seedling, the internode portion is cut into a small section, the length of 1.5-2.5 cm above the small section is maintained, the length of 6-8 cm of the cuttage portion below thesection is maintained, and the internode portion is cut into an inclined surface at an inclination angle of 30-40 degrees; the cut seedling is soaked in a soaking solution for soaking processing; sandy soil is mixed with assisting medium, high-temperature and high-pressure sterilization is conducted for 30-35 minutes under the temperature of 121 DEG C, sterilization is conducted, the mixed mediumis placed at room temperature for 2-3 hours, the mixed medium is prepared into a rectangular medium bed with the size of 1 m*5 m after the mixed medium is cooled down, the height of the medium bed is20-25 cm, and cuttage seedling breeding is conducted on processed seedlings on the rectangular medium bed with the size of 1 m*5 m. According to the method, the rootage of cuttage seeds is robust anduniform, there exist almost no short roots and slender roots, the yield and quality of subsequent pueraria lobata and the rooting rate and survival rate of the cuttage seeds are increased.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a method for efficiently cultivating kudzu seedlings. Background technique [0002] Pueraria lobata belongs to the perennial vine deciduous plants of the Fabaceae Papilionaceae. The medicinal plants of Pueraria lobata have the effects of promoting body fluid and quenching thirst, relieving muscle and reducing fever, dredging meridians and activating collaterals, promoting yang and quenching thirst, and detoxifying alcohol. It can be made into products such as Pueraria lobata beverage, Pueraria lobata health-care oral liquid, and Pueraria lobata health-care jelly powder. High medicinal value and nutritional value, it is an important regional economic crop. People can obtain a small amount of kudzu resources by digging in the field, but with the increase of market demand and the continuous reduction of wild kudzu resources, digging in the wild can no longer meet people's deman...
