Patchouli leaves often rotate with other crops, it is not resistant to strong light exposure and frost, so it rotates with rice most of the time.

Cut about a section of 40cm branches, it is best to choose the broken pulp is white, with cutting along with planting, hole planting, hole distance of about 20-25cm. Insert the cut cuttings into the cuttings, half the length of the seedlings, about half the length of the seedlings, cover the soil after cutting, avoid the sun before the branches take root, so cover the grass and water more.

3. Field management

It can take root after planting for more than 20 days, and fertilization can be carried out at this time. The initial fertilization can be diluted with manure and urine fertilizer and then diluted with water, and then fertilized every other half month for 2-3 times in a row. The second fertilization uses 350 kilograms of human feces and urine per mu, and the third time, in addition to applying 350 kilograms of human feces and urine, 3.5 kilograms of ammonium sulfate should be added, which should be diluted with water and then applied.
