Abstract

The invention discloses a soil ginseng single-leaf cutting propagation method, which comprises the following steps: watering the soil thoroughly, making it muddy and spreading it flat. Collect fresh soil ginseng single leaves, one-fifth to one-third of the length of the tip of the single leaf, insert into the soil, the upper epidermis of the leaf is upward, part of the lower epidermis is in contact with the soil, and the base of the petiole is in contact with the soil and exposed to the air. Cuttings should have a certain density, keep warm and moisturize, light 10-14 hours a day, and keep dark for 10-14 hours to keep the soil moist. After taking root and sprouting and growing more than 3 new leaves, spray the foliar fertilizer once. When the seedlings reach a height of 0.05 meters, they can be transplanted, and the seedling rate can reach 90%, or even higher. During the whole process, the soil ginseng plants obtained from single-leaf cuttings can bloom within 3 months. The invention has the advantages of simple and convenient operation, low cost and short breeding cycle, and can breed native ginseng in different seasons.

Description

A kind of native ginseng single-leaf cutting propagation method

technical field

The invention relates to the technical field of cultivation and propagation, in particular to a single-leaf cutting propagation method of native ginseng.

Background technique

Talinum paniculatum (Jacq.) Gaertn., also known as false ginseng, American ginseng, Taiwan wild ginseng, soil Korean ginseng, ginseng vegetable, etc., is a perennial herbaceous angiosperm plant of the genus Panax ginseng in the family Portulaca oleracea. It is native to the tropics and has long been a popular vegetable in many areas of West Africa and Latin America. It is cultivated in central and southern China, as well as in Taiwan Province. Soil ginseng has fewer diseases and less insects, and its roots and leaves can be eaten. It can be fried, made into soup, rinsed, or stewed. Vegetables. Soil ginseng is also a good traditional Chinese medicine. The root is a nourishing and strong medicine, nourishing the middle and nourishing qi, nourishing the lungs and promoting body fluid; the leaves reduce swelling and detoxify, and treat boils and boils. People have carried out studies on morphological characteristics, physiological and biochemical, chemical components, pharmaceutical identification, etc., and have also done research on its artificial cultivation and propagation techniques, but there are still some key technical issues that have not been fully resolved in artificial propagation, which limits the Its large-scale production and industrialization development. The current cutting propagation of native ginseng requires cutting off the growing stem, which limits the growth of the original plant, and the reproduction coefficient is relatively small.

Contents of the invention

The object of the present invention is to overcome above-mentioned shortcoming and provide a kind of simple and easy operation, low cost, can not only protect the stem of original plant growth, but also can expand the multiplication coefficient soil ginseng single-leaf cutting propagation method.

A kind of snakeberry cutting propagation method of the present invention comprises the following steps:

(1) Arrangement of soil ginseng single-leaf cutting sites

The soil (0.3≤cohesive soil volume: fine sand volume≤10) is poured with water, made into mud, and spread flat.

(2) Single-leaf cuttings of native ginseng

Collect a single leaf of fresh soil ginseng, one-fifth to one-third of the length of the tip of the single leaf, inserted into the soil, the upper epidermis of the leaf is upward, part of the lower epidermis is in contact with the soil, and the base of the petiole is in contact with the soil and exposed to the air , The cutting density is 0.03-0.05 meters apart from the plants x 0.05-0.1 meters apart from the rows.

(3) Light treatment after cutting

Keep a relative humidity of more than 75%, a temperature of 15-35 degrees Celsius, and keep good light, 10-14 hours of light every day and 10-14 hours of darkness, water in time to keep the soil moist.

(4) Seedling cultivation

After taking root and sprouting and growing more than 3 new leaves, spray the foliar fertilizer once. When the seedling grows to a height of 0.05 meters, it can be transplanted, and the seedling will be ready in three months.

Compared with the prior art, the present invention has obvious advantages and effects. It can be seen from the above technical scheme: the propagation coefficient of propagation by single-leaf cuttings is 4-6 times larger than that of ordinary cuttings; the land is made into mud and smoothed To reduce soil water loss, ensure that the tip of the soil ginseng blade can absorb enough water when it is inserted into the soil, and at the same time provide the water for the new roots to germinate at the base of the petiole; Under the stimulation of stimuli, the growth of bud points is induced to produce new stems and leaves. At the same time, under good conditions such as good light, temperature, humidity and air, the root primordia at the base of petioles are stimulated to grow, new roots are produced, and the roots extend into the moist The soil can provide inorganic salt and water in time for the old leaves and new leaves of the cuttings, accelerate photosynthesis, and promote the growth of new shoots; this method is faster than ordinary leaf cuttings and branch cuttings, and new roots and new shoots grow faster. Maintain a relative humidity of more than 75% to moisturize the growth of seedlings and prevent young leaves from being burned. In short, through heat preservation, moisture retention, ventilation, light and other treatments, the rapid propagation of soil ginseng single-leaf cuttings in different seasons can be realized without being affected by the seasons.

Detailed ways

Below by implementing examples, in conjunction with the beneficial effects of the present invention, further illustrate:

In a ventilated plastic greenhouse, the soil (0.3≤cohesive soil volume: fine sand volume≤10) is thoroughly watered, made into mud, and spread flat. Collect a single leaf of fresh soil ginseng, one-fifth to one-third of the length of the tip of the single leaf, insert it into the soil, the upper epidermis of the leaf is upward, part of the lower epidermis contacts the soil, and the base of the petiole contacts the soil and is exposed to the air. The cutting density is 0.03-0.05 meters between plants and 0.05-0.1 meters between rows, maintain a relative humidity of more than 75%, and a temperature of 15-35 degrees Celsius. , keep the soil moist. After 5 days, the petiole bases of the single leaves of 30 soil ginseng from the new cuttings began to take root and sprout. After growing more than 3 new leaves, spray Luoxiaowang foliar fertilizer once. When the seedlings reach a height of 0.05 meters, they can be transplanted, and the seedling rate can reach 90%, or even higher. Three months later, more than 30% of the native ginseng plants obtained by single-leaf cuttings have bloomed, and some have already hung young and tender fruits.

The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Any simple modification, Equivalent changes and modifications still fall within the scope of the technical solution of the present invention.
