Detailed Explanation of Greenhouse Cilantro Cultivation Techniques and Management Points

Cilantro is a vegetable commonly used in our daily lives to add flavor, and it is deeply favored by consumers. With the development of the planting industry, many vegetables are grown in greenhouses, and growing cilantro in greenhouses yields higher profits. So how can you grow greenhouse cilantro to make it grow better? Let's take a look at greenhouse cilantro cultivation techniques below.

1. Land preparation and fertilization

Before planting, the plot must first be prepared and fertilized. Choose sandy loam soil that is loose, fertile, and well-drained for planting. Along with plowing, apply 3000 kg of decomposed manure per mu as base fertilizer, then make beds 2 m wide. If the soil is too dry, water it to keep it moist. After raking the soil fine and leveling it, wait for sowing.

2. Selecting good seeds

For greenhouse cilantro, varieties that grow quickly, tolerate heat, and have strong disease resistance and adaptability are generally chosen. Cilantro can be divided into large-leaf and small-leaf varieties. Although the yield of small-leaf varieties is not as high as that of large-leaf varieties, their fragrance is rich, and they have strong cold resistance and adaptability, so small-leaf varieties are generally chosen.

3. Germination promotion and sowing

Cilantro likes cool conditions and is suitable for growing at a temperature of 15-20 degrees, so the sowing time is generally from August to April. Before sowing, in order to increase the germination rate and make the seedlings emerge uniformly, germination promotion treatment is generally carried out first. First, put the seeds into warm water at about 50 degrees, stir continuously and soak for 15-20 minutes. After the water temperature drops, continue soaking the seeds for 18-20 hours, then place them in a greenhouse environment to promote germination, wetting them once every 2-3 days. Generally after 10 days, the seeds can be sown once they show white sprouts. Sowing can be done in rows or by broadcasting, generally sowing 2 kg per mu. After sowing, cover the ground with a layer of rice straw and spray water frequently to keep it moist. After the seedlings emerge, remove the rice straw promptly, and do a good job of thinning and filling in seedlings.

4. Field management

Cilantro likes cool conditions but fears high temperatures and strong light, so when planting, consider setting up shade netting to provide shading and cooling, which is beneficial to the growth of cilantro and increases yield. During the seedling stage, you can combine loosening the soil with pulling out weeds in the field so they do not compete for nutrients. During the growth period, keep the soil in a state that is neither dry nor wet. During the seedling stage, water as little as possible, while during vigorous growth, supply sufficient fertilizer and water to make it grow quickly. Fertilization is mainly with urea and nitrogen-potassium fertilizer, with 10-15 kg applied per mu as topdressing, which can be done together with watering.

5. Harvesting

Because greenhouse-grown cilantro grows quickly, it should be harvested promptly once it reaches the harvesting standard to avoid bolting. Generally, it can be harvested when cilantro grows to 25 cm. The harvesting time should be well controlled, preferably in the early morning and afternoon, as this helps improve its commercial value.
