We need to consider not only the ecological environment it needs, but also the national standards for traditional Chinese medicine. We should choose flat, fertile, sunny and easy to drain and irrigate soil that meets the national planting standards in all aspects. The second is to apply more base fertilizer, mainly compost, manure, organic fertilizer. Land preparation for the ridge, according to the different terrain were made into flat ridge and high ridge.

2. Cultivation: Schizonepeta is generally sown in March and April of spring and ninety-one in autumn, and the most common way of reproduction is seed reproduction. We need to select mature, full, dark brown or tan color, no pest damage seeds, broadcast or drill the way to sow. Generally, the row spacing should be kept at about 20 cm. The seeds should be evenly scattered, and then covered with soil. Pay attention to the use of feet, and to properly water, keep the soil moist, so as to promote emergence.

3. Field management: Generally, it takes about ten days and a half months for seedling emergence. Our field management of Schizonepeta is generally divided into three stages: seedling stage management, growth stage management and late growth stage management. During the seedling stage of Schizonepeta, that is, when the seedlings are about four or five centimeters, an intertillage and weeding should be carried out, and when the seedlings grow to about eight to ten centimeters, it is necessary to start thinning and planting.
