Problems solved by technology

At present, most traditional Chinese medicine adopts sowing or drilling for field seedling cultivation. After sowing, grass or straw is laid to cover moisture. Due to the uncontrollable conditions such as water and fertilizer, the soil is easy to harden when it is dry, and the root water cannot be discharged when the water is sufficient.
On the one hand, poor soil ventilation will hinder the growth and development of the seedling root system, and the general problem of low emergence rate
On the other hand, root rot caused by fungi is very prone to occur due to long-term water accumulation in the roots, which seriously affects the quality and output of traditional Chinese medicine seedlings.
After emergence, most of the seedlings of traditional Chinese medicine are afraid of the sun and like to be in the shade. Nowadays, shade nets are usually used for seedling cultivation, which requires labor such as building and dismantling the shade net, which has become a factor that increases the cost of growing Chinese medicine seedlings.
At the same time, the fertility of field soil supply for raising seedlings is low, and the growth of seedlings is not vigorous. During the wintering period, the growth points of the stem tips are often frozen to death or eaten by small animals; damaged

Embodiment 1

[0028] Lu Codonopsis Seedlings

[0029] Such as figure 1 , figure 2 As shown, a traditional Chinese medicine nursery bed includes a three-sided rectangular bed body 1 and a baffle plate 2, and gauze nets 3 are arranged on both sides of the rectangular bed body 1 to facilitate drainage when watering is too much; Two vertical edges on one side of the hollow surface of the body 1 are provided with baffle plates 4, and the baffle plate 2 is inserted into the hollow surface of the rectangular bed body 1 through the baffle plates 4 to form a rectangular seedling bed.

[0030] In this embodiment, the method for raising seedlings of Lu Codonopsis using the above-mentioned traditional Chinese medicine nursery bed specifically includes the following steps:

[0031] (1) Site selection and preparation: The nursery bed is selected in a large field plot with deep soil, ventilated light and good drainage, and the first crop is selected from corn and other gramineous crops; choose the north-south ...

Embodiment 2

[0041] Bupleurum seedlings

[0042] (1) Site selection and preparation: the nursery bed should be selected in a field plot with deep soil, ventilated light and good drainage. The first crop should be leguminous crops; choose southwest direction, digging width 17cm, depth 25cm, sloping around A trapezoidal pit with a length of about 15 degrees and the length depends on the actual situation, and the distance between the pits is 27cm;

[0043] (2) Planting of shade crops: First plant broad beans around the nursery bed with a plant spacing of 8-10cm. Seedlings can emerge within 15 days after sowing, and buds and branches can be seen in 30 days to achieve shading effect. Bupleurum seeds relies on broad bean plants to shade and avoid direct sunlight within one month after emergence of Bupleurum seedlings, and then cut broad beans to facilitate the lighting of Bupleurum seedlings; at the end of October, the aboveground stems and leaves of broad beans will directly cover the seedbed;

Embodiment 3

[0052] Astragalus seedlings

[0053] (1) Site selection and preparation: The nursery bed is selected in a field plot with deep soil, ventilated light, and good drainage. The first crop is gramineous; choose the southwest direction, digging width 17cm, depth 25cm, sloping around A trapezoidal pit with a length of about 15 degrees and a length according to the actual situation. The distance between the pit and the pit is 30cm;

[0054] (2) Planting of shade crops: first plant tartary buckwheat around the nursery bed with a plant spacing of 6cm. Seedlings can emerge after 15 days of sowing, and buds and branches can reach the sunshade effect after 25 days. Rely on the tartary buckwheat plant for shading and avoid direct sunlight within 1 month after the seedlings of Scutellaria baicalensis Georgi, and then shorten the tartary buckwheat seedlings to facilitate the lighting of the seedlings; at the end of October, the aboveground stems and leaves of tartary buckwheat will directly cover...

Abstract

The invention belongs to the technical field of traditional Chinese medicine planting, and particularly relates to a traditional Chinese medicine seedling bed and a seedling method thereof. The methodcomprises the steps of planting sunshade plants, preparing a seedling bed, sowing, managing after sowing and taking seedlings out of a greenhouse. Water and fertilizer storage functions are achievedthrough the design of the seedling bed, seedlings can absorb water and nutrient substances from the seedling bed according to own needs, and most importantly, root diseases of the seedlings are inhibited. During seedling culture, sunshade plants are planted, seedling culture can be performed without using a sunshade net, labor such as sunshade net building and dismounting after seedling emergenceis avoided, and planting cost is reduced; and overwintering seedlings can be kept in warm after the overground parts of the plants wither in winter, and the survival rate of the seedlings is increased. When the traditional Chinese medicine seedlings are transplanted, the seedlings can be collected by opening the seedling bed, and damage to the traditional Chinese medicine seedlings due to manual digging is reduced. The method has the advantages that the occurrence rate of root rot of traditional Chinese medicine seedlings can be reduced, the emergence rate is high, labor is reduced, and the seedling cost is reduced.

Description

Technical field [0001] The invention belongs to the technical field of planting Chinese medicinal materials, and specifically relates to a Chinese medicinal seedling breeding bed and a seedling raising method thereof. Background technique [0002] Traditional Chinese medicine seedling cultivation technology is a key technology in the cultivation of medicinal materials, which has a significant impact on the yield and quality of medicinal materials. At present, most traditional Chinese medicines use broadcast or drill seeding to raise seedlings in the field. After sowing, mulch with grass or straws is used for moisturizing. Due to the inability to control water, fertilizer and other conditions, the soil tends to harden during drought, and the root moisture cannot be discharged when moisture is sufficient. Poor soil aeration on the one hand will hinder the growth and development of seedling roots, and there is a general problem of low seedling emergence. On the other hand, root rot...
