Planting method capable of improving content of volatile oil in herba menthae

Abstract

The invention discloses a planting method capable of improving the content of volatile oil in herba menthae. Sufficient nutrients are provided for growth of the herba menthae through soil preparationand fertilization processes; absorption of the nutrients by the herba menthae is promoted through a watering process, and the evaporation loss of the volatile oil is reduced; and through a yield-increase management process, the number of blades is increased, flowering of the herba menthae is inhibited, insect pests are reduced and the content of the volatile oil is improved. According to the planting method, soil preparation is carried out by using plowing equipment, and soil blocks are dispersed into soil particles, so that contact between laid fermented canal mud, loess and straw powder andsoil is fuller and more uniform, the nutrients more easily permeate into the soil, and the plowing equipment improve the content of the volatile oil in the herba menthae through improving the nutrients in the soil. According to the planting method, the insect pests are killed by using a red-blue disinfestation lamp to increase yield, and the red-blue disinfestation lamp effectively kills the insect pests, so that the rate of diseases and insect pests of the herba menthae is greatly reduced and the content of the volatile oil in the herba menthae is improved.

Description

technical field [0001] The invention relates to the field of peppermint cultivation, in particular to a planting method for increasing the volatile oil content of peppermint. Background technique [0002] Peppermint is one of the traditional Chinese medicines commonly used in my country, and it is also an important spice plant. Peppermint has the effects of dispelling wind, cooling, and detoxifying. It is used to treat wind-heat cold, headache, red eyes, sore throat, toothache, etc. Peppermint Stems and leaves contain volatile oil, the main active ingredient of which is menthol. Peppermint oil and menthol are widely used in the fields of medicine and hygiene, daily chemicals, and food processing. [0003] Therefore, the patent application number CN201711064114.2 discloses a planting method for increasing the volatile oil content of peppermint, including: pruning, flower suppression, conditioning, topdressing; pruning old branches in spring, and spreading organic fertilizer to...

[0003] Therefore, the patent application number CN201711064114.2 discloses a planting method for increasing the volatile oil content of peppermint, including: pruning, flower suppression, conditioning, topdressing; pruning old branches in spring, and spreading organic fertilizer to promote branching, Inhibit the fall of mint leaves, increase the growth of mint leaves, and increase the volatile oil content of mint; spray flower inhibitor solution on mint in mid-to-late June to inhibit the flowering and fruiting of mint, promote the growth of mint stems and leaves, and increase the oil gland density of mint leaves. Improve volatile oil content, can antibacterial and desinsection simultaneously, strengthen the disease resistance of peppermint, avoid stem and leaf withered and yellow, improve peppermint yield, but still have the following deficiencies: (1) this planting method planting mint fresh leaf yield per acre is less than 500kg , the average yield of peppermint oil per mu is relatively low, and the economic benefits of growers are poor, which greatly affects the enthusiasm of growers. Moreover, the fertility of the planting soil is insufficient, the supply of nutrients is poor, the growth and development of mint leaves is slow, the leaves are small and The internal mint volatile oil content is low, and the mint reproduces and grows during the flowering period, which consumes a large amount of soil and its own nutrients, which will also cause low volatile oil content in the mint and affect the economic benefits of mint planting; (2) existing planting methods The ground is not evenly plowed, so that the soil and fertilizers cannot be well integrated, so that the soil nutrients are insufficient, which affects the growth of mint; (3) the planting method does not prevent pests, which makes the pests serious when planting mint, resulting in low yield of mint. poor quality
