Peppermint should be planted in places with sufficient light and convenient irrigation and drainage. The soil should not be too acidic or too alkaline. The terrain is relatively flat and the soil is relatively fertile, which is more conducive to its growth.However, after planting once, it can not continue to plant for three years.After finding the land, it is necessary to carry out deep ploughing first, and apply the decomposed compost, superphosphate and bone meal as base fertilizer to the land, rake fine and turn the fertilizer into the soil.
There are three ways to raise seedlings.Rootstock seedling raising is generally carried out in April or August, the strong and disease-free plants are selected as mother plants, the stems and leaves on the ground are cut off in early winter, and the rhizomes are left in the ground.When the seedlings grow to 15 centimeters, the seedlings should be planted separately.Cuttings in May-June, cut 10 cm long branches, cuttings to the seedbed, until rooting and germination can be transplanted.
In the growth process of mint, first of all, we should check the situation of seedlings, and make up for the lack of seedlings.When it's done, start weeding. Eliminating weeds can prevent them from competing for nutrients and promote the growth of seedlings.When they grow to 10-15 centimeters high, they can supplement a little urea, which should be applied 10 kilograms per mu.In the early stage of growth, it needs to be watered once every 15 days, and it needs to be watered 4-5 times from seedling emergence to harvesting.
The main diseases of mint are black shank, rust and leaf blight.Among them, black shank mainly occurs in the seedling stage, which will cause the base of the stem to turn black and rot, making it lodging and withering, generally using chlorothalonil or carbendazim to control.Rust often occurs from May to July and can be treated with triadimefon.Spot blight is common from May to October, and can be controlled by spraying zineb once a week.
