Planting method for increasing content of mint oil in mint

Abstract

The invention discloses a planting method for increasing the content of mint oil in mint. The method includes the following steps of firstly, preparing a land, wherein plowing and rotary tillage are conducted on planting soil so as to refine soil particles, fermented river silt is laid on the soil, then loess and straw powder are laid, and a chlorothalonil solution and an EM fungicide are sprayedto air the loess and straw powder; secondly, conducting planting, wherein planting of mint seedlings is conducted in May, the straw powder is laid at the bottoms of planting pits, and water is pouredon the land till the soil is moisturized; thirdly, conducting fertilizer applying and watering, wherein the fermented river silt and inorganic fertilizer are applied on the planting land in July and September, and different watering frequencies are adopted in the 15 days before mint seedling planting, in the growth stage and in the one month before harvesting; fourthly, conducting yield increase management, wherein bud picking is conducted on mint plants in cloudy days in the beginning of June, a mineral growth agent is added to sprayed water every week to be sprayed, a growth inhibitor is sprayed before flowering of the mint plants in August, and four red and blue light insect killing lamps are arranged in each mu of mint planting area.

Description

technical field [0001] The invention belongs to the technical field of peppermint planting, and in particular relates to a planting method for increasing the content of peppermint oil in peppermint. Background technique [0002] Mint, also known as Yindancao, is a herb of Lamiaceae. The whole plant is green and fragrant, with opposite leaves and small flowers in lavender color. It mostly grows beside rivers in mountain wetlands, and its rhizomes grow horizontally underground, generally at an altitude of 2100 The area above rice; mint can be used as medicine and can be eaten.

It has a good curative effect on symptoms such as fever, throat, and gum swelling, and it has high edible and medicinal values. Mint planting areas are widely distributed in the temperate regions of the northern hemisphere, and the Chinese production areas are mainly distrib...

AI Technical Summary

Problems solved by technology

[0003] The present invention is aimed at the existing problems: the current planting technology mint fresh leaf output per mu is about 500kg, the average yield per mu of peppermint oil is relatively low, and the economic benefits of the growers are poor, which greatly discourages the enthusiasm of the growers for planting. It has good medicinal value and a stable market, but in recent years, the planting area and output of mint have been declining; 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 content of volatile oil in mint is low Propagation and growth of peppermint during flowering period will consume a lot of soil and its own nutrients, which will also cause low volatile oil content in peppermint, which will affect the economic benefits of peppermint planting
