Mint is also known as mint, mint leaf, mountain mint, etc. It is the dried above-ground fraction of the mint of the Lamiaceae family, which is used for medicinal purposes and is cultivated throughout the country. Below we introduce the key points of mint cultivation techniques and teach you how to grow mint and what you need to pay attention to. 1. How to select and prepare land for planting mint

Choose a sunny, flat, fertile plot with convenient drainage and irrigation. Loose, fertile, and well-drained noisy soil is preferred. Water has a great influence on the growth and development of mint. Plants require more water in the early and middle stages of growth.

When preparing the land, apply 5000kg of circle fertilizer and 50kg of compound fertilizer per acre, plow 20cm deep, harrow and level it, make a 1m wide flat or high border, and open 4 small trenches of 3cm deep in the border for planting. 2. Mint planting methods

The rhizome propagation (planting) method is generally used in production. It is mostly planted in spring in Shandong and other places, but in winter in Jiangsu and Zhejiang regions. Spring planting is between the Spring Equinox and Qingming Festival, and winter planting is from late October to early November.

When planting, dig out the thick, white rhizomes, cut them into root segments of about 8 cm, and bury them in the potting soil to grow new plants in about 20 days.

The rhizomes should be planed and cut while planting to prevent excessive water loss from affecting survival. About 60 to 100kg of seed stems are used per acre. Generally, 1 acre of mint roots can be planted in 5 to 10 acres. 3. Watering and fertilizing in mint cultivation

Mint grows rapidly, and the number of harvests per year is also different in different regions. To speed up mint growth and increase mint yields, adequate fertilizer must be applied. Sichuan base fertilizers are generally based on stable manure, cake fertilizer and bone meal. In addition to applying base fertilizer, top dressing still needs to be carried out on time.

After the mint emerges, it is necessary to loosen the soil and weed frequently to keep the field clean. And make sure to water it frequently with little water, and water it when there is drought, so as to keep the soil moist and promote the growth of its stems and leaves.

When the seedlings are 15cm tall and top-dress in time after each harvest, mainly nitrogen fertilizer (15kg urea per mu) or 1500kg of human waste per mu plus 8kg of thiamine and 50kg of water should be applied in a ditch next to the seedlings. Down. Supplemented with phosphorus and potassium fertilizer (10kg diammonium phosphate). Water after application to promote rapid growth of stems and leaves. 4. How to harvest and process mint

When the top leaves of mint become pagoda-shaped, the leaves are dark green, and a small part of the leaves at the base turn yellow, it can be harvested. After harvesting, place it on a slate floor or clean sand, spread it thinly and expose it to the sun. Turn it over once at noon to allow it to receive sunlight evenly and achieve consistent color.

Let it bask in the sun for several times, then pile it on the floor of the house to regain moisture, and then dry it in the sun. If it rains, you can spread it out and tie it into small handfuls and hang them in a ventilated place, and then dry them in the sun on a sunny day.

During the drying process, be careful not to get damp or get damaged. Each acre can harvest 250-350 kilograms of dry goods (approximately 2 kilograms of fresh goods are equivalent to 1 kilogram of dry goods). 5. Precautions for planting mint

After planting mint seedlings, be careful to avoid direct sunlight, otherwise it will affect the normal growth of mint. After mint is planted, its roots have not adapted to the new soil, so be careful not to fertilize it. Pay attention to the later maintenance. Mint is not tolerant to waterlogging and needs to be watered appropriately.

During winter, mint needs to control water after it goes dormant and stop fertilizing. 6. Prevention and control of mint diseases and insect pests

The pathogen of rust is polyspora among fungi, which damages the leaves. Prevention and control methods: drain the accumulated water in the ground in time to reduce the soil humidity; spray 25% of 1000 times of fentanin in the early stage of the disease for 2 to 3 times in a row.

White star disease: mainly damages the leaves and occurs from summer to autumn. Prevention and treatment methods: Remove diseased leaves promptly when found. In the early stage of the disease, spray Bordeaux liquid 1:1:120 times for 2 to 3 times in a row.

Black stalk disease: It damages the stems and becomes serious when the soil is too wet or the humidity in the field is too high. Prevention and control methods: To treat the disease in the seedling stage, cultivating the soil and spraying 1000 times of 70 grams of pine can be carried out 1 to 2 times.

Insect pests: small cutworm: damage to seedlings, control method: light trapping and killing of adults. Use 90 trichlorfon 1000 times liquid to water; Beet exigua moth: damages the leaves, control method: spray 90 trichlorfon original powder 800 times liquid.
