Detailed Explanation of the Key Points of Soilless Cultivation Techniques for Cilantro
Cilantro is very common in our daily lives, and with the continuous development of planting techniques, cultivation models have also undergone tremendous changes. The most famous of these is soilless cultivation technology. Soilless cultivation of cilantro can increase yield, make management easier, and effectively reduce cultivation costs. So how should cilantro be cultivated without soil? Below, the editor brings you the soilless cultivation techniques for cilantro. Let's take a look!
1. Site Selection and Garden Establishment
The first step in soilless cultivation of cilantro is to choose a good planting plot. The area around the planting plot must have an ample and clean water source, good ventilation, and sufficient electricity. After choosing the planting base, build the cilantro cultivation greenhouse. When building the greenhouse, pay attention to taking measures to isolate it from the outside. For example, the places where the greenhouse film contacts the ground and the skylights, to prevent pests, diseases, and animals from intruding. Soilless cultivation mainly uses foam boards as cultivation boards. Control the cultivation density well and punch cultivation holes in the foam boards. Specialized cultivation boards for soilless cultivation can be purchased on the market.
2. Timely Sowing
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 with higher temperatures, low-temperature germination promotion should be done before sowing. After treating the seeds, sow the seeds on seedling-raising sponges. Because cilantro leaves are bifoliate, sowing should not be too deep. After sowing, water regularly to increase moisture and promote seed germination. Wait until the seedlings emerge and grow two cotyledons, then begin spraying nutrient solution to promote nutrient absorption by the seedlings. When 1-2 more leaves have grown, they can be transplanted at the appropriate time.
3. Nutrient Management
After transplanting, cilantro seedlings mainly absorb nutrients through their roots. When providing nutrients, we should focus on cyclic use to reduce cultivation costs. The concentration of the nutrient solution mainly depends on the growth of the 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. Also, during the cultivation process, foliar fertilizer should be sprayed regularly to promote photosynthesis in the cilantro, increase 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, doing a good job of isolating the greenhouse from the outside, and doing good disinfection and sterilization work before cultivation. Reduce the number of pathogens and insect eggs, lower the incidence rate, and try to avoid the use of 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 soilless cultivation techniques for cilantro. The growth cycle of soilless-cultivated cilantro is about one month. It is also more convenient to harvest than traditional cultivation and easier to store. Therefore, soilless cultivation technology is an innovation in agricultural planting in our country, and I hope everyone can learn from it! That is all for today's introduction.
