Why Are Your Soilless Vegetables Failed
"No matter what type of soilless cultivation is used, several basic links must be mastered. The nutrient solution must be dissolved in water and then supplied to the root system of the plant. In the soilless cultivation of the substrate, the nutrient solution is poured into the substrate and then absorbed by the root system of the crop. Therefore, we must understand the physical and chemical properties of water quality, nutrient solution and the substrate used.
1. Water Quality
The water quality of soilless cultivation is closely related to the configuration of nutrient solution. The main indicators of water quality are electrical conductivity (EC), PH value and whether the content of harmful substances exceeds the standard.
EC is an indicator of the salt concentration in a solution. Various crops have different salt tolerance, such as sugar beet, spinach, and cabbage with strong salt tolerance. Moderate salt tolerance such as cucumbers, beans, bell peppers, etc.
Soilless cultivation has strict requirements on water quality, because it does not have buffer capacity like soil cultivation, so the content of many elements is lower than the allowable concentration standard of soil cultivation, otherwise plants will be easily poisoned.Some farmland water is not necessarily suitable for soilless cultivation. It is a good way to collect rainwater for soilless cultivation. The PH value of the water should not be too high or too low, because generally the crops have the best requirement for the PH of the nutrient solution to be neutral. If the PH value of the water itself is high or low, it is necessary to adjust it with acid or alkali, which is a waste of medicine and time-consuming. work.
2.Nutrient Solution
Nutrient solution is the key to soilless cultivation, and different crops require different nutrient solution formulations. There are many formulas published in the world, but they are similar, because the original formula comes from the chemical composition analysis of the soil extract. In the nutrient solution formula, the biggest difference is the ratio of nitrogen and potassium. The purity and cost of chemical reagents should be taken into account when configuring nutrient solutions, and chemical fertilizers can be used to reduce costs.
3.Planting Cube
Our Tenlead Planting Cube is a growing medium made from phenolic foam. It provides a high quality,sterile and inert root growing environment. Hydroponic growing cube provides from 90%-98% air space in between its fibers while still giving excellent support for the plant. It is sterile and inorganic. Because it does not contain any organic matter, it helps to protect the root zone from harmful microorganisms.
What most important is that it is biodegradable and will completely biodegrade after a period of time without polluting the environment. Conversely, some products that cannot be decomposed, such as rock wool, will take you a lot of time and cost to handle after planting. We firmly believe that it will be more valuable and expand its market in the future nursery garden work. And our products do not contain any chemicals, allowing plants to grow healthier. Unlike soil, our plant growing cube does not block any nutrients. All elements in the nutrient solution can be used in plants, i.e. there is no soil interference. It is also effective in eliminating fungi and diseases common to young plants./It can also effectively eliminate the common fungi and diseases of young plants.
4.Watering System
There are many ways to supply liquid in soilless culture, including Nutrient Film Technique (NFT), flood irrigation method, drip irrigation system, siphon method, spray method and artificial watering. In summary, it can be divided into two categories: circulating water (closed circuit system) and non-circulating water (open circuit system). Now NFT and drip irrigation are widely used in production.
