A detailed explanation of the planting methods and key technical points for lemongrass
Lemongrass is a perennial herbaceous plant of the grass family, also known as lemon grass. It is one of the common herbs and is often used to extract essential oil. The whole plant can be used as medicine and has the effects of disinfecting, sterilizing, and treating neuralgia and muscle pain. So how should it be planted? Let's take a look together.
1. Site selection and land preparation
Lemongrass has low requirements for soil, and ordinary soil can be used for planting, but it is not suitable to plant it in saline-alkali land or sandy soil. In addition, it is afraid of drought, so the planting site is required to have convenient irrigation and drainage, and the previous crop is best to be cereals, beans, or vegetables. After selecting the land, plow the plot 20 cm deep, apply decomposed farmyard manure as fertilizer, and then form ridges or make beds. Because lemongrass seeds are relatively small, it is essential to level and harrow the soil and wait for sowing.
2. Sowing
Lemongrass is sown from March to April. There are two methods: direct sowing and seedling transplanting. Direct sowing can also be divided into drilling or broadcasting. For drilling, open furrows on the bed surface or on the ridge at a row spacing of 30 cm and a furrow depth of 7-10 cm. After mixing the seeds with plant ash, sow them into the furrows, paying attention to the spacing between seeds, and then cover with soil. If the soil is dry, water appropriately. For broadcasting, first water the soil thoroughly to keep it moist, then evenly scatter the seeds on the seedbed, cover with soil, and water. When broadcasting, pay attention to density. Seedling transplanting can be carried out after the previous two methods. When the seedlings grow to a certain height, transplant them elsewhere.
3. Field management
From after sowing until the seedlings emerge, weed control should be done well so that there are no weeds in the field, which is beneficial for seedling emergence. When the seedlings grow to 4-6 cm, carry out the first thinning combined with weeding, and the second thinning at 13-17 cm. During thinning, remove diseased and pest-damaged seedlings and weak seedlings, keep strong seedlings, and the excess seedlings can be transplanted. Each year, carry out 3-4 times of intertillage and weeding, and apply topdressing once after each weeding to speed up seedling growth. Generally, apply human and livestock manure water, or apply nitrogen fertilizer in spring and summer.
