Embodiment 1

[0029] Step 1, prepare the chamomile α-bisabolol bulking agent for use, the chamomile α-bisabolol bulking agent is ALA solution, and the concentration of the ALA solution is 1.0mmol.L -1 -4.0mmol.L-1;

[0030] Step 2, the test material of the present invention is chamomile (Matricaria recutita) seeds, and the chamomile seeds are sown in a nutrient bowl (20cm * 20cm) after soaking and accelerating germination, and the cultivation substrate is vermiculite, coconut shell powder and perlite and 1 : Mix evenly at a ratio of 1:1, place the seedlings in a greenhouse with a day / night photoperiod and temperature of 16h / 8h, 24°C / 18°C, and a relative humidity of 70%;

[0031] Step 3, the first application: when the chamomile germinates for a week, get the chamomile α-bisabolol extender prepared above and directly smear or spray it on the root of the chamomile, and the dosage of each chamomile root is 10ml;

[0032] Step 4, the second application: After about two weeks after the emergenc...

Embodiment 2

[0033] Example 2 Effect of ALA treatment on the growth of chamomile

[0034] After the steps in embodiment 1 were completed, measure experimental group 1, experimental group 2, experimental group 3 and control group chamomile aerial part dry weight, underground part dry weight and total dry weight in embodiment 1 respectively, and summarize as follows figure 2 ,in, figure 2 In , different lowercase letters indicate a significant difference at P<0.05.

[0035] from figure 2 It can be concluded that the dry weight of the aboveground part, the dry weight of the underground part and the total dry weight of chamomile are all based on 2.0 mmol.L -1 ALA (experiment 2) treatment was the highest, reaching 774.05mg, 57.38mg and 831.43mg respectively, which were 23%, 27% and 23.3% higher than that of the control group; and the dry weight of the three concentrations of ALA treatment was higher than that of the control group, But when the concentration of ALA is 1.0~2.0mmol.L -1 , ...

Embodiment 3

[0036] Example 3 Effect of ALA Treatment on Photosynthesis of Chamomile Leaves

[0037] Steps 1-3 are the same as in Example 1. Step 4, the second application: after about two weeks after the emergence of the seedlings, the field planting began, and three plants were planted in each nutrient pot, and 50 pots were planted in total. One week after chamomile planting, 40 pots of chamomile with roughly the same growth were selected, and exogenous ALA was used for foliar spraying treatment, with a setting of 1.0mmol.L -1 (Experimental group 1), 2.0mmol.L -1 (Experiment 2) and 4.0mmol.L -1 (Experimental group 3) three kinds of concentrations, and with spraying clear water as contrast. Since ALA is easy to decompose when exposed to light, it is treated every time when the light is weak in the evening, with the leaf back moist as the degree, and once every two weeks, for a total of 10 treatments. During this period, the cultivation and management measures of each treatment were co...

Abstract

The invention provides a method used for increasing the content of alpha-bisabolol in flores Chamomillae. The method is capable of increasing the content of alpha-bisabolol in flores Chamomillae greatly, and comprises following steps: after one week of flores Chamomillae germination, and after one week of flores Chamomillae field planting, a flores Chamomillae alpha-bisabolol increasing agent is directly smeared onto or sprayed onto the roots or leaf surfaces of flores Chamomillae, wherein the flores Chamomillae alpha-bisabolol increasing agent is a 5-aminolevulinic acid (ALA) solution with aconcentration of ALA ranging from 1.0 to 4.0mmol.L<-1>. The method is capable of increasing the growth amount of flores Chamomillae, improving the oxidation resistant system of flores Chamomillae, improving the stress resistance of flores Chamomillae, increasing the content of alpha-bisabolol in flores Chamomillae, and increasing the medical value and the economical value of flores Chamomillae. The adopted ALA is nontoxic; no pollution is caused by ALA; light decomposition of ALA is easily caused; and ALA is safe for plants and animals, and the environment. The method is applied based on appropriate time and technology, labor intensity is reduced, and yield increasing and quality improving are realized.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a method for increasing the content of chamomile α-bisabolol. Background technique [0002] Chamomile, also known as Matricaria recutita L., is an annual or perennial herb of the genus Matricaria in the Asteraceae family. It is native to Western Europe, Europe and some temperate regions. , antioxidant, antibacterial, anti-inflammatory, antispasmodic, analgesic and other medicinal effects, it is a medicinal plant with great development value, and is widely used as an additive in spices, cosmetics and medicines. The identification analysis of its volatile oil shows that the active ingredients mainly include terpenoids, flavonoids and ester volatile oils and other compounds. Terpenoids are the main active components of chamomile, and α-bisabolol is one of the main components of terpenoids. Although chamomile α-bisabolol has important pharmacological and physiologic...
