Cilantro Soilless Cultivation Technology and a Detailed Explanation of the Entire Planting Process
How do you grow cilantro with soilless cultivation? With the development of technology, cilantro cultivation techniques have also been constantly changing, going through a process of soil cultivation - substrate cultivation - water-soil cultivation, and soilless cilantro cultivation uses a series of cultivation facilities and prepared nutrient solutions and other modern techniques to grow cilantro, which is both convenient and labor-saving. The soilless cilantro cultivation technology is introduced below:
I. The process of soilless cilantro cultivation
1) Choose a good site, preferably an area with good ventilation, with water and electricity.
2) When building the site, especially when building the greenhouse, all side films and skylights that come into contact with the outside must be isolated with insect-proof netting.
3) Use foam boards as cultivation boards for growing the plants. Drill holes in the boards according to a certain plant spacing and row spacing, or they can be determined according to the size of the plants being cultivated. The standard specification for cilantro cultivation is generally 80 plants per cultivation board.
4) Sowing. Cilantro seeds are generally sown in autumn and winter, when the temperature is suitable for seed germination. If the temperature is high, low-temperature germination promotion is needed. After the seeds are treated, sow them in sponge cubes of similar size. Since cilantro seeds are dicotyledonous, they should be sown shallowly. After sowing, place the plant seeds in one place for centralized management, spray water regularly, and maintain the moisture of the sponge cubes to facilitate better and faster sprouting. After the seeds sprout and grow 2 cotyledons, begin spraying nutrient solution at this time to ensure nutrient absorption, and also to improve the sturdiness of the seedlings and lay the foundation for rapid growth in the future. When the cilantro seedlings have 3-4 leaves, they can be transplanted to the cultivation seedbed for growing.
II. Management after transplanting, generally mainly referring to nutrient management and pest and disease management.
Nutrient management has two aspects. One is that most of the nutrients are absorbed by the plant roots. The nutrients here are generally used in a circulating manner to save unnecessary waste. It is determined according to the growth stage of cilantro. Generally, the EC of nutrients at the seedling stage is between 1.0-1.2, at the middle stage between 1.4-1.6, and before harvest the concentration can be increased to 1.8 to improve growth vigor. The second is that during cultivation, foliar fertilizer should be sprayed regularly to promote photosynthesis, increase chlorophyll formation in the plant, and avoid yellowing caused by insufficient light.
Pest and disease management is mainly based on prevention. The insect-proof netting in the outer space can prevent pests from entering the greenhouse. Multiple overall sterilization and disinfection before cultivation can reduce the number of future disease and pest occurrences, truly achieving pesticide-free cultivation. In addition, ultraviolet sterilization lamps and strong magnetic generators are used to treat the nutrient solution, which improves the activity of the water and has a sterilizing effect.
III. Harvest
When cilantro has been cultivated for about 20-30 days, it can be harvested. With this planting model, cilantro is extremely convenient to harvest and has no soil, making it very clean. Even if it cannot be sold that day, placing it in water to soak can still maintain its freshness.
Soilless cilantro cultivation makes fertilizing convenient, and no pesticides need to be sprayed, making it both green and healthy. Cilantro of this quality is very popular in the market, and off-season cultivation can be achieved, effectively improving the planting benefits of cilantro.
