preparation example Construction

[0026] The invention provides a method for preparing Kuqin, comprising the steps of:

[0027] (1) The seedlings are grown for 1-2 years, and the seedlings can be carried out in any existing conventional manner known to those skilled in the art, preferably the seedlings are grown for 2 years; It is more conducive to the formation of dead heart of Scutellaria baicalensis, and the growth of seedlings for 1-2 years, and then transplanted for 2-3 years, especially after the first 2 years of seedling growth, and then transplanted for 2 years, it is most conducive to the formation of dead heart;

[0028] (2) 2-3 years of growth after transplanting, preferably 2 years of growth after transplanting, the control cultivation conditions are:

[0029] The cultivation density is adjusted at a row spacing of 25-35cm, a plant spacing of 8-16cm, preferably a row spacing of 25-30cm, and a plant spacing of 12-16cm;

[0030] Control the cultivation soil environment, sandy soil / loamy soil ≥ 1, pr...

Embodiment 1

[0037] Cultivate Kuqin according to the following method.

[0038] (1) seeding, seedling growth for 2 years;

[0039] (2) transplanting, growth 2 years, control cultivation condition is:

[0040] The planting distance is 12cm, and the row spacing is 25cm.

[0041] The cultivation soil environment is all sandy soil,

[0042] Detect the soil properties and get: the soil pH value is 7.0, and the target pH value is 8.2. Therefore, the soil pH value is adjusted by adding lime to make the soil pH value reach 8.2.

[0043] It was detected that the content of soil organic matter was 0.10%, total nitrogen 0.01%, total phosphorus 0.02%, total potassium 0.50%, available nitrogen 4.0mg / kg, available phosphorus 2.0mg / kg, and available potassium 25.0mg / kg. According to the difference between the current soil property conditions and the target conditions, calculate the amount of fertilizer that needs to be applied. According to the calculated amount of fertilizer, apply organic fertilizer...

Embodiment 2

[0046](1) seeding, seedling growth for 2 years;

[0047] (2) transplanting, growth 2 years, control cultivation condition is:

[0048] The planting distance is 16cm, and the row spacing is 35cm;

[0049] The cultivation soil environment is, all are sandy soil / loamy soil=1,

[0050] Detect soil properties, obtain soil pH value and organic matter, nitrogen, phosphorus, potassium and other elements, adjust the soil according to the test results, so that the soil properties meet the following conditions: pH7.3, organic matter 1%, total nitrogen 0.1%, total phosphorus 0.05% , total potassium 1.1%, available nitrogen 23.0mg / kg, available phosphorus 10.0mg / kg, available potassium 43.0mg / kg;

[0051] (3) 45 days before the excavation, the soil moisture content was detected every 5 days, and the required watering amount was calculated according to the difference between the detection result and the target condition, and watered according to the calculation result, so that the soil mo...

Abstract

The invention provides a wizened scutellaria cultivation method. The method particularly comprises the steps that 1, seedlings grow for 1-2 years; 2, after transplanting is conducted, the seedlings grow for 2-3 years, wherein the cultivation conditions are that the cultivation density is adjusted to reach the line spacing being 25-35 cm and the row spacing being 8-16 cm, and the cultivation soil environment is controlled with the sand / loam being larger than or equal to 1, the soil pH value being 7.3-8.2, the organic matter being 0.15-1%, total nitrogen being 0.03-0.10%, total phosphorus being0.02-0.05%, total potassium being 0.8-1.1%, available nitrogen being 9.0-23.0 mg / kg, available phosphorus being 3.0-10.0 mg / kg and available potassium being 30.0-43.0 mg / kg; 3, digging is conducted, wherein the soil water content is kept to be 8-18% 30-60 days before digging. Wizened scutellaria obtained through the cultivation method can form a very obvious dead heart, and compared with the deadheart of wizened scutellaria obtained through a control method, the length is increased by 29.0-48.6%.

Description

technical field [0001] The invention relates to a method for cultivating Kuqin, in particular to a cultivation method for improving the production efficiency of Kuqin. Background technique [0002] Scutelaria baicalensis Georgi is a perennial herbaceous plant of the genus Scutellaria in the Labiatae family. Its roots are used as medicine, which tastes bitter and cold in nature. Due to the long growth period of Scutellaria baicalensis, the dark brown or tan withered phenomenon that gradually appears downward from the center of the root head is called dead heart. Scutellaria baicalensis with a full interior and no dry heart is called "tiaoqin"; Scutellaria baicalensis with a dry heart is called "kuqin". "Tiaoqin" and "Kuqin" have different effects: Tiaoqin is good at clearing large intestine fire, and Kuqin is good at clearing lung fire. Therefore, based on the different effects, when making formulas for different diseases, there are people who choose "Tiaoqin" and others. T...
