Description

Technical Field

[0001] The present invention belongs to the technical field of Scutellaria baicalensis Georgi planting, and particularly relates to a Scutellaria baicalensis Georgi planting method. Background Art

[0002] Scutellaria baicalensis Georgi Scutellaria baicalensis Georgi Scutellaria baicalensis Georgi is a perennial herb of the genus Scutellaria in the family Lamiaceae. Its dried roots are dug in spring and autumn for use as medicine. Its aliases include mountain camellia root, Scutellaria tea, and earth gold tea root. It is cold in nature and bitter in taste, and has the effects of clearing heat and drying dampness, purging fire and detoxifying, stopping bleeding and preventing miscarriage, and detoxifying and stopping bleeding. The clinical antibacterial effect of Scutellaria baicalensis Georgi is significant, and it is not easy to produce drug resistance, so it has high medicinal value. It is mainly used to treat lung heat cough, erysipelas swelling and pain, hematemesis and epistaxis, damp-heat jaundice, hepatitis, dysentery, etc. There are 1,150 pharmaceutical preparations with Scutellaria baicalensis Georgi as a component in the "National Standard Compilation of Chinese Patent Medicines", and nearly 70% of the commonly used Chinese patent medicines contain Scutellaria baicalensis Georgi. In recent years, studies have found that Scutellaria baicalensis Georgi also has the effects of antiviral, anti-tumor, antioxidant, antibacterial, and free radical scavenging, and can be used to treat respiratory infections, pneumonia, colitis, hepatitis, and allergic diseases.

[0003] The existing breeding methods of Scutellaria baicalensis Georgi are seedling breeding and seed processing. The reproduction speed and efficiency of seeds and seedlings are also the key factors restricting the breeding efficiency of medicinal plants and the popularization and planting of new varieties. Tissue culture technology can achieve the purpose of rapid, efficient, and high-quality breeding of Chinese medicinal materials seedlings. First, small segments of Scutellaria baicalensis Georgi stem nodes are inoculated into LS medium and cultured to light brown callus. Through technical optimization experiments such as induction, differentiation, rejuvenation of test-tube seedlings, and rooting of Scutellaria baicalensis Georgi callus, it is found that the nodes of Scutellaria baicalensis Georgi are the most ideal explants for inducing callus, but the grown test-tube seedlings are relatively weak. Later, many scholars have studied and improved the tissue culture and rapid propagation technology of Scutellaria baicalensis Georgi, but the effect is still not ideal enough. The industrialized tissue culture seedlings of Scutellaria baicalensis Georgi have not been realized in production yet. Therefore, at present, the cultivation of Scutellaria baicalensis Georgi is mainly by direct seeding and seedling raising, but the existing Scutellaria baicalensis Georgi seeds and medicinal materials have low yields and cannot meet the requirements of large-scale and standardized production of high-quality Scutellaria baicalensis Georgi. Summary of the Invention

[0004] To solve the above problems, the present invention provides a Scutellaria baicalensis Georgi planting method.

[0124] Select a test plot in the experimental demonstration base of Chifeng Institute of Animal Husbandry and Veterinary Sciences in Chengzi Township, Songshan District, Chifeng City, Inner Mongolia Autonomous Region. The total area is 5.5 mu, which is evenly divided into 11 plots, each with an area of 0.5 mu, numbered 1-11 respectively. Then, Scutellaria baicalensis Georgi is planted by the methods of Example 1 and Comparative Examples 1-10 respectively. The seeds of Scutellaria baicalensis Georgi are from Guoyao Seed Industry, and the corresponding management is shown in Table 1. The corresponding results are shown in Table 2.

[0125] Table 1 Management of the test plot Table 2 Results of the management of the test plot As can be seen from Table 2, compared with the late sowing period on May 03, the early sowing period on April 17 increased the seed yield per mu by 50.12%, the emergence rate of Scutellaria baicalensis Georgi seeds increased by 10%, and the purity and germination rate of the seeds were also significantly improved. In the density comparison, the 30×40 density combination had the highest seed yield.

[0126] In addition, compared with the application of chemical fertilizers, the treatment with 100 catties / mu of zero-degree microbial fertilizer had the highest root yield and seed yield, which was 23.2% higher than that of the chemical fertilizer group. The emergence rate of Scutellaria baicalensis seeds increased by about 10%, and the seed purity and germination rate were also significantly improved. The S3307 uniconazole at a concentration of 60 mg / L had the most significant effect on improving the quality of Scutellaria baicalensis seeds, with a 26.9% increase in yield. The emergence rate of Scutellaria baicalensis increased by about 10%, and the seed purity and germination rate were also significantly improved. Stubble retention had the most significant effect on improving the quality of Scutellaria baicalensis seeds, with a yield increase of more than 30%. The emergence rate of Scutellaria baicalensis increased by about 10%, and the seed purity and germination rate were also significantly improved.

[0127] To increase the mu yield of Scutellaria baicalensis seeds, spray 90 grams / mu of potassium dihydrogen phosphate foliar fertilizer. The seed yield per mu is 9.778 kg, which is 87.46% higher than the control; for the sowing date on April 17, the seed yield per mu is 6.067 kg, which is 16.3% higher than the control; with a row spacing of 30 cm and a plant spacing of 40 cm, the seed yield per mu is 6.603 kg, which is 26.60% higher than the control; spray S3307 uniconazole at a concentration of 60 mg / L, the seed yield per mu is 6.226 kg, which is 19.36% higher than the control; apply 100 catties / mu of zero-degree microbial fertilizer as base fertilizer, the seed yield per mu is 7.424 kg, which is 42.33% higher than the control; with a stubble height of 30 cm, the seed yield per mu is 3.921 kg, which is 88.93% higher than the control; the comprehensive improvement is more than 25%.

[0128] To increase the seed germination rate and purity, spray 90 grams / mu of potassium dihydrogen phosphate foliar fertilizer. The seed germination rate reaches more than 90%, which is 16.3% higher than the control; for the sowing date on April 17, the seed germination rate reaches more than 90%, which is 9.6% higher than the control; with a row spacing of 30 cm and a plant spacing of 40 cm, the seed germination rate reaches more than 90%, which is 13.2% higher than the control; spray S3307 uniconazole at a concentration of 60 mg / L, the seed germination rate reaches more than 90%, which is 17.8% higher than the control; apply 100 catties / mu of zero-degree microbial fertilizer as base fertilizer, the seed germination rate reaches more than 90%, which is 15.8% higher than the control; with a stubble height of 30 cm, the seed germination rate reaches more than 90%, which is 7.2% higher than the control; there is no significant difference in seed purity except for a large increase in the sowing date, ensuring the high quality of the seeds.

[0129] To improve the disease resistance of Scutellaria baicalensis, no diseases occurred in the present invention, especially the resistance to root rot was significantly improved, and the incidence of root rot was zero.

[0130] To increase the content of medicinal components in Scutellaria baicalensis, such as baicalin, in actual production, the vast majority of annual Scutellaria baicalensis does not meet the harvesting standards, and the content of baicalin in it fails to reach the pharmacopoeia requirements, i.e., <9%. Therefore, only the content of baicalin in biennial or perennial Scutellaria baicalensis is detected. Spraying potassium dihydrogen phosphate at 90 g / mu of foliar fertilizer, the content of baicalin is 13.61%, which is 25.76% higher than that of the control; for the sowing date on April 17, the content of baicalin is 13.12%, which is 24.14% higher than that of the control; with a row spacing of 30 cm and a plant spacing of 40 cm, the content of baicalin is 14.32%, which is 35.78% higher than that of the control; spraying S3307 uniconazole at a concentration of 60 mg / L, the content of baicalin is 12.54%, which is 18.64% higher than that of the control; applying 100 catties / mu of zero-degree microbial bacterial fertilizer as base fertilizer, the content of baicalin is 13.11%, which is 14.03% higher than that of the control; with a stubble height of 30 cm, the content of baicalin is 11.45%, which is 8.33% higher than that of the control; this increases its market value.

[0131] In summary, by planting according to the method of Example 1, the estimated seed yield of the obtained Scutellaria baicalensis is increased by 50.12%, the germination rate of the harvested seeds reaches over 90%; the purity reaches over 85%; there is no occurrence of root rot disease, and the content of baicalin in it is about 13.5%, far greater than the pharmacopoeia requirement of 9%.
