Embodiment 1

[0027] In order to compare the specific effect of the commercial quality of Astragalus membranaceus produced after direct transplanting of untreated wounded seedlings and the commercial quality of Astragalus membranaceus produced after transplanting the wounded seedlings processed by the present invention, three tests were carried out altogether, three test times From March 25, 2013 to October 25, 2013, from March 22, 2014 to October 26, 2014, and from March 15, 2015 to October 22, 2015, the experiment was conducted in the agricultural The breeding base of new varieties of Chinese medicinal materials in the Science and Technology Innovation Park of the Academy of Sciences has an altitude of 1910m, an average annual temperature of 7.0°C, sunshine hours of 2200h, rainfall of 400mm, and a frost-free period of 140d. It belongs to the Loess Plateau area and has a temperate continental monsoon climate. The soil is sandy loam, the soil is fertile, and the texture is loose, which is co...

Embodiment 2

[0044] Embodiment 2 is substantially the same as Example 1, and the only difference is that the wounded part of the seedling is completely immersed in the rooting solution for the treatment of the wounded seedlings, and the soaking time is 7 seconds. The rooting solution consists of the following parts by weight Material composition: 35 parts of indole butyric acid, 15 parts of naphthaleneacetic acid, 50 parts of boric acid, medical vitamin B 12 10 parts of injection and 5 parts of carbendazim, the preparation method of rooting solution is: first completely dissolve indole butyric acid and naphthalene acetic acid with 95% alcohol to form solution A for use, and then use distilled water to dissolve boric acid and medical vitamin B 12 Completely dissolve with carbendazim to form solution B for later use, mix solution A and solution B and make it constant volume to solution C, wherein the mass fraction of indolebutyric acid in solution C is 30%, and the mass fraction of naphthalen...

Embodiment 3

[0057] Embodiment 3 is substantially the same as Example 1, and the only difference is that the wounded part of the seedling is completely immersed in the rooting solution for the treatment of the wounded seedlings, and the soaking time is 6 seconds. The rooting solution consists of the following parts by weight: Material composition: 32 parts of indole butyric acid, 13 parts of naphthaleneacetic acid, 45 parts of boric acid, medical vitamin B 12 9 parts of injection and 4 parts of carbendazim, the preparation method of rooting solution is: first completely dissolve indolebutyric acid and naphthalene acetic acid with 95% alcohol to form solution A for use, and then use distilled water to dissolve boric acid and medical vitamin B 12 Completely dissolve with carbendazim to form solution B for later use, mix solution A and solution B and make solution C, wherein the mass fraction of indolebutyric acid in solution C is 28%, and the mass fraction of naphthaleneacetic acid is 9 %, t...

Abstract

The invention belongs to the technical field of crop culture, and particularly relates to a culture method for radix astragali seedlings with damaged roots. The method is used in radix astragali culture. The method is characterized in that for seedlings which are damaged by scratching, cutting, perforation and breaking in the seedling lifting process, the roots of the damaged seedlings are soaked in a rooting solution for 5-7 seconds before transplanting; and after transplanting, the row spacing of the seedlings is 30-40cm, the interplant spacing is 10-15cm, the depth is 8-10cm, the seedlings are placed flat in ditches, and a full stand of 14000-15000 seedlings is kept per mu. The use of the method obviously increases the use rate of the seedlings, greatly improves the problem that the quality of radix astragali products declines due to the root damage to the seedlings in the prior art, and lowers the seedling raising cost.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a method for cultivating astragalus seedlings with wounded roots. Background technique [0002] Astragalus membranaceus is a well-known commonly used traditional Chinese medicinal material. Astragalus membranaceus is warm in nature and sweet in taste. Its main functions include invigorating qi, strengthening the surface, diuresis, excretion of concentration, and promoting muscle growth. It is a commonly used tonic traditional Chinese medicine in the past dynasties. Since the 1970s, a large number of studies have been conducted on the chemical components of Astragalus plants at home and abroad. The results show that the chemical components of Astragalus include polysaccharides, flavonoids, saponins, amino acids, proteins, riboflavin, folic acid and so on. In traditional Chinese medicine, astragalus mainly treats diseases such as lack of food and loose stools, ...
