Peppermint planting technique

Peppermint is one of the commonly used traditional Chinese medicines in China. It is a cool antipyretic for sweating, treating influenza, headache, red eyes, body heat, throat, gums and other diseases. External use can treat neuralgia, skin itching, rash and eczema. Usually replace tea with peppermint, clear heart and clear eyes. Let's take a look at the planting techniques of mint.

1. Propagation of peppermint rhizome:

It is better to plant Greater Cold at the end of winter. First of all, spread barnyard manure on the selected land and plough it into the soil with a depth of about 1500 kg per mu as base manure. The ploughing field is about 0.8 mi 1 foot deep, which is fine, raked flat, 4 feet wide and 8 inches deep. Then, choose a strong, fat white rhizome, cut into about 8-inch nodes, each node must have a new bud. Open a sowing ditch on the prepared soil moisture with a depth of 6 inches and a distance of 0.8 meters. According to 6Mel 8 inch plant distance, put the truncated node directly in the sowing ditch, pay attention to the first end of each section must be exposed more than 1 inch of soil, after each ditch, that is, cover the soil compaction, and then open a second trench, immediately after planting watering or irrigation, about half a month can take root, begin to sprout new buds. Use 75kg per mu.

Second, peppermint cutting propagation:

Generally choose the stout aboveground stem from May to June, remove the tip, cut into 8-inch long nodes, according to 6-inch plant spacing, 8-inch row spacing, obliquely inserted on the soil moisture, timely irrigation, often keep the soil moist, about 15 days can survive. The survival rate of this method is low, and the yield and quality are not as good as that of rhizome propagation. Therefore, it is generally not used.

III. Mint field management:

Weeding should be done frequently before seedlings are unearthed to seal ridges. In case of drought, timely irrigation should be needed to keep the soil moist. Soil agglomeration should be loosened at any time. When the seedlings grow to 5ml, 6 inches, the first fertilizer can be applied, with urea 8 kg per mu and dung 1500 kg per mu. Combined with irrigation to facilitate absorption, mint can be harvested for the first time in the Beginning of Summer season.

Fertilize immediately after harvest, sprinkle 12 kilograms of urea per mu under the plant, then irrigate and weed. When the new seedlings grow to 3 houses and 4 inches high, apply fine cruller, and timely watering (not watering in case of rainy season). Harvest mint for the second time before and after the Beginning of Autumn. After harvest, it is still appropriate to increase fertilizer according to the above method, and harvest for the third time after the frost falls. Farm manure should be applied at this time to protect the persistent roots through the winter, and seedlings are easy to emerge at the beginning of spring next year.
