A large number of elements of water soluble fertilizer methods and techniques

Nowadays, a large amount of elemental water-soluble fertilizer is a new type of fertilizer. Compared with traditional fertilizers, it is not only rich in formula, but also very flexible in application. It can be soiled, so that the roots of plants can be fully exposed to fertilizers and breathe all kinds of nutrients. Spraying on the surface, entering the interior of the plant through the stomata of the foliar to improve the absorption and utilization of fertilizer; it can also be drip irrigation and soilless cultivation, saving irrigation water and improving labor productivity. In the process of fertilization, in order to achieve the best results, it is necessary to combine the characteristics of water-soluble fertilizers to master certain fertilization techniques.
1. Avoid direct application, and take a second dilution method. Because the water-soluble fertilizer is different from the general compound fertilizer, the farmers can not use the conventional fertilization method, resulting in uneven fertilization, the phenomenon of burning seedlings, seedlings and seedlings weakening, secondary dilution to ensure uniform fertilizer, and improved fertilizer utilization. rate.
2. Strictly control the amount of fertilizer applied. The water-soluble fertilizer has higher nutrient content than the general compound fertilizer, and the amount is relatively small. Because of its quick-acting effect, it is difficult to remain in the soil for a long time. Therefore, it is necessary to strictly control the amount of fertilizer to avoid the loss of fertilizer, that is, to reduce the economic benefits of fertilization, and to achieve the goal of high yield, high quality and high efficiency.
3. Try to use it alone or in combination with non-alkaline pesticides. For example, when vegetables are deficient in deficiency or root growth is poor, many farmers use water-soluble fertilizers to alleviate them. Remind farmers that water soluble fertilizer should be applied alone or mixed with non-alkaline pesticides to prevent metal ions from reacting to produce sediment, causing leaf damage or phytotoxicity.
