Functional fertilizer refers to fertilizers that have other functions in addition to a small amount of nutrients to supply vegetables, such as promoting vegetable rooting, improving plant resistance or improving disease resistance of vegetables, so when vegetables have certain problems At the time, vegetable farmers often use functional fertilizers to adjust the growth of plants, and often achieve good results. However, when the reporter interviewed Gucheng Street in Shouguang City, many vegetable farmers asked the reporter: Why is the functional fertilizer used better in the first two times, but after continuous use alone, the effect is less and less obvious?
It turned out that some vegetable farmers saw that the effect was obvious when they started to use functional fertilizers, which promoted the growth of vegetables. Therefore, functional fertilizers can also meet the demand for mineral elements in vegetable growth. Long-term continuous use of functional fertilizers alone, the effect is less and less obvious. The reason is that when the functional fertilizer was first used, the original fertilizer used in the soil was more, the nutrient content was sufficient, and the mineral fertilizer was not used in a short time. The functional fertilizer used can also promote the absorption and utilization of mineral elements by vegetables. Meet the needs of vegetable growth.
However, because most of the functional fertilizers have low levels of mineral nutrients, if they are not used together with water-soluble fertilizers or compound fertilizers, the amount of nitrogen, phosphorus, potassium and other trace elements in the soil will become less and less, resulting in longer vegetables. The worse the difference, the functional fertilizer cannot be used continuously.
