Does soilless agricultural products affect people's health?
Soilless cultivation is not a new thing, but due to my country's national conditions, many people do not have access to soilless cultivation of agricultural products. At present, soilless culture has also been promoted in my country, and the methods are more diversified. In addition to traditional water-absorbing media such as perlite or nutrient solution for planting, there are also some planting methods that adopt spraying, planting and breeding symbiosis, etc. Soil cultivation of agricultural products. However, no matter what kind of soilless cultivation mode is used for agricultural products, the impact on our health is basically negligible.
First of all, soilless culture is less likely to be infected by pests and diseases. Under the traditional agricultural production mode, since soil is the most direct and basic growth medium, it is inevitable that there will be a certain chance of being infested by some pests, causing crops to fail to grow normally, what should be done? Use pesticides, insecticides, etc. for treatment. The soilless culture uses aqueous solutions, perlite and spray as the growth medium, and does not touch the soil, and the probability of being infected by soil-borne pests is almost zero. Moreover, the current soilless cultivation can be upgraded to a condition that isolates the growth of the external environment in a closed environment, and there are diseases and insects in the external environment without contact with crops, and the incidence of diseases and insects can also be greatly reduced. Therefore, agricultural products grown in soilless culture mode have unique advantages compared with traditional agricultural products in terms of pesticide residues.
Secondly, the nutrient solution and spray used in soilless culture are also relatively safe. Soilless agricultural products also need nutrient supply to grow and mature normally. Different from traditional soil cultivation, the roots of soilless crops are soaked in water or nutrient solution most of the time, and the roots absorb the nutrients in the water or nutrient solution to grow. Relatively speaking, the composition of the nutrient solution is not essentially different from the fertilizer solution in the soil. It is just a solution of salt particles formed by dissolving nutrients in water. However, due to the low nutrient content and single nutrient types in the water medium, it is inevitable that some plant endogenous hormones or fungicides to prevent root rot will be added to the nutrient solution. However, the content of these ingredients is relatively low, and will not affect the health of consumers.
Finally, the agricultural products of soilless cultivation are similar to those of traditional fertilizers. After all, it is an agricultural product grown out of the soil. Even if the nutrient solution is used, the nutrient content and nutrient types will not be formulated to be similar to the soil, especially for some of the various amino acids, monosaccharides, and middle and trace elements in the soil. The nutrient solution still has certain disadvantages. Therefore, the quality of soilless cultivated products is no problem, but in terms of nutrition and palatability, it is actually no different from soil cultivated agricultural products.
Therefore, soilless agricultural products will basically not have any impact on the health of consumers. Instead, it has obvious advantages in pesticide residues due to its own characteristics.
