The role of water-soluble fertilizers with a large number of elements
A large number of element water-soluble fertilizers have the functions of promoting growth and activation, promoting root and seedling growth, fruit expansion, detoxification and senescence, biological weight resistance, disease resistance and fertilizer protection. According to the fertilizer demand characteristics of different crops, the corresponding fertilizers have different formulations. There are special water-soluble fertilizers for all kinds of crops, such as vegetables, fruit trees, flowers, grain, cotton, oil and so on.
How to use a large number of element water-soluble fertilizers?
The main results are as follows: 1. To avoid direct irrigation, the secondary dilution method should be adopted. Because the water-soluble fertilizer is different from the general compound fertilizer, it can not follow the conventional fertilization methods, resulting in uneven fertilization, burning the roots of seedlings, weak seedlings and other phenomena, secondary dilution to ensure uniform fertilizer and improve fertilizer utilization efficiency.
2. The amount of fertilizer application should be strictly controlled. The nutrient content of water-soluble fertilizer is higher and the amount of water-soluble fertilizer is relatively less than that of general compound fertilizer. Because of its strong quick effect, it is difficult to remain in the soil for a long time, so it is necessary to strictly control the amount of fertilizer application, avoid fertilizer loss, that is, reduce the economic benefits of fertilization, and can not achieve the goal of high yield, high quality and high efficiency.
3. Try to use it alone or mixed with non-alkaline pesticides. For example, in the case of vegetable deficiency or poor root growth, many farmers often use the method of spraying water-soluble fertilizer to alleviate it. Water-soluble fertilizer should be applied alone or mixed with non-alkaline pesticides as far as possible to avoid precipitation caused by the reaction of metal ions, resulting in leaf fertilizer damage or drug damage.
The above is the introduction of the role of water-soluble fertilizers with a large number of elements. I hope it will be helpful to you.
