Embodiment 1
[0035] Select 5 acres of hillside land with sandy loam soil, soil layer thickness of more than 30cm, and naturally loose soil as the planting plot. The plot has sunny slopes, no irrigation conditions, sufficient sunlight, and an altitude of 600-800m.
[0036] The specific steps of using this plot to optimize the planting of imitation wild Scutellaria baicalensis and the results of related costs and yields are as follows.
[0037] From April to May, use small machinery to plow the land to a depth of more than 30cm; combined with land preparation, apply 15,000kg of decomposed farmyard manure, N:P 2 o 5 :K 2 O=16:18:15 nitrogen, phosphorus and potassium compound fertilizer 125kg, combined with site preparation, rake the fertilizer and 10-15cm deep soil together and mix them evenly, and lay them flat for sowing.
[0038] Select new seeds with plump grains, 95% purity, and 86.55% germination rate, soak them in 0.2% potassium permanganate solution for 12 hours, rinse them with cle...
Embodiment 2
[0046] Embodiment 2 is identical with embodiment 1 basic steps, and difference is that embodiment 2 mainly utilizes unmanned aerial vehicle to carry out the spraying of herbicide, water-soluble plant nutrient and ethephon. Wherein, the herbicide is 75 times liquid of 24% clethodim, and the dosage of the liquid medicine is 10L. Water-soluble plant nutrient 1 and water-soluble plant nutrient 2 are mixed with 30L of water, and the dosage of medicinal solution is 10L. 1.5% Ethephon 10L.
[0047] Scutellaria baicalensis has been planted in the wild for 3 years, and the quality of the tested medicinal materials has reached the pharmacopoeia standard. It was excavated when the aboveground part of the scutellaria baicalensis plant withered on October 12 in autumn. When digging, try to preserve the root system, randomly sample plants to measure the root weight of each plant, and investigate the number of retained plants per mu and the yield per mu.
[0048] Through statistical analys...

Abstract
The invention relates to a planting method of wild-imitating scutellaria baicalensis. The method comprises the following steps of land selection and preparation, base fertilizer application, seed selection, sowing at a proper period, reasonable close planting, weed removal, foliar topdressing, chemical bud removal and scientific harvesting. The method provides a series of cultivation measures for increasing yield of wild-imitating scutellaria baicalensis, such as selecting improved varieties and conducting seed treatment, keeps weeds in a seedling stage, and sprays selective herbicides when the weeds grow too vigorously and exceed scutellaria baicalensis seedlings to produce an inhibitory effect on growth of the scutellaria baicalensis. According to plant nutrition demand characteristics of scutellaria baicalensis in different growth periods, different water-soluble plant nutrient solutions are sprayed to leaf surfaces, a root shoot ratio is regulated and controlled, underground root growth is promoted, and plant stress resistance is improved. Particularly, timely selection of herbicides and foliar topdressing for foliar spraying of the different water-soluble plant nutrient solutions in different growth periods can be carried out by adopting an unmanned aerial vehicle, so that production efficiency can be greatly improved and production cost can be reduced. The method is particularly suitable for large-scale planting of the wild-imitating scutellaria baicalensis and has a wide application prospect.
Description
technical field [0001] The invention relates to the technical field of planting Chinese medicinal materials, in particular to a planting method imitating wild scutellaria baicalensis. Background technique [0002] Scutellaria baicalensis Georgi is a plant of the genus Scutellaria baicalensis in the Labiatae family. Its dried roots are used as medicine. It is one of the commonly used bulk medicinal materials in China. It was first recorded in "Shen Nong's Materia Medica". , Modern pharmacological research shows that Scutellaria baicalensis has antipyretic, anti-inflammatory, antibacterial, antiviral, antitumor and other effects, and is called "Chinese medicine antibiotics". [0003] In recent years, wild scutellaria baicalensis resources are in short supply, and cultivated scutellaria baicalensis has become the main commodity drug source. Imitation of wild cultivation does not occupy farmland, the quality of medicinal materials is close to that of wild ones, and the quality ...
