The Latest Technical Method Tutorial for Soilless Cultivation of Cilantro
Cilantro is very common in our daily life, and with the continuous development of planting techniques, planting models have also undergone tremendous changes. Among them, the most famous is soilless cultivation technology. Soilless cultivation of cilantro can increase yield, facilitate management, and effectively reduce planting costs. So how should cilantro be cultivated soillessly? Below, the editor brings you the soilless cultivation technology for cilantro. Let's take a look!
1. Site selection and garden establishment
The first step in soilless cultivation of cilantro is to select a good planting plot. Around the planting plot, there must be sufficient clean water sources, good ventilation, and sufficient electricity. After selecting the planting base, build the cilantro planting greenhouse. When building the greenhouse, attention must be paid to measures that isolate it from the outside. For example, the places where the greenhouse film contacts the ground and the skylights, etc., to prevent invasion by pests, diseases, and animals. Soilless cultivation mainly uses foam boards as cultivation boards. Control the cultivation density well and punch cultivation holes in the foam boards. Cultivation boards specially used for soilless cultivation can be purchased on the market.

Cilantro planting generally begins sowing and raising seedlings in autumn and winter, because the temperature in autumn and winter is favorable for cilantro seed germination. If sowing in summer or other times when the temperature is relatively high, low-temperature germination promotion work must be done before sowing. After treating the seeds, sow the seeds on seedling-raising sponge, because cilantro leaves are double leaves, so sowing should not be too deep. After sowing, water regularly to increase moisture and promote seed germination. When the seedlings emerge from the soil and grow two cotyledons, begin spraying nutrient solution to promote the seedlings' nutrient absorption. When 1-2 more leaves have grown, they can be transplanted at the appropriate time.
3. Nutrition management
After transplanting, the main nutrient absorption of cilantro seedlings is through the roots. When we provide nutrients, we should mainly focus on recycling use to reduce planting costs. The concentration of the nutrient solution mainly depends on the growth of cilantro. For example, during the seedling stage, the nutrient solution concentration is usually around 1.1, and when growing to the middle stage, it is increased by about 0.4. In the late growth stage, in order to promote the maturity of the cilantro plants and strengthen nutrient absorption, the concentration should be increased to around 1.9. In addition, during the cultivation process, foliar fertilizer should be sprayed regularly to promote photosynthesis in cilantro, increase the chlorophyll in the leaves, and prevent leaf chlorosis caused by insufficient light.
4. Pest and disease control
Although the use of soilless cultivation technology can reduce the incidence of pests and diseases, some pests and diseases will still occur if management is poor. For pest and disease control, we mainly focus on prevention, do a good job in isolating the greenhouse from the outside, and do a good job in disinfection and sterilization before cultivation. Reduce the number of pathogens and insect eggs, lower the incidence rate, and try to avoid using pesticides. Also, when using nutrient solution, carry out ultraviolet sterilization and other work on the nutrient solution to improve its vitality and eliminate pathogens in it.
The above is a brief introduction to the soilless cultivation technology of cilantro. The growth cycle of soilless-cultivated cilantro is about one month. Moreover, harvesting is more convenient than traditional cultivation, and storage is also easier. Therefore, soilless cultivation technology is an innovation in our country's agricultural planting, and I hope everyone can learn from it! That is all for today's introduction.
