Water-soluble fertilizer refers to a compound fertilizer containing nitrogen, phosphorus, potassium, calcium, magnesium, trace elements, amino acids, humic acid, alginic acid and the like which can be completely dissolved in water. There are two types of solid water soluble fertilizer and liquid water soluble fertilizer. From the nutrient content, there are a large number of elements of water-soluble fertilizer, medium-quantity water-soluble fertilizer, trace element water-soluble fertilizer, amino acid-soluble fertilizer, humic acid-containing water-soluble fertilizer, organic water-soluble fertilizer, etc.
As a quick-acting fertilizer, water-soluble fertilizer has more comprehensive nutrient elements, and has different formulas according to the fertilizer characteristics of different crops. The market sells vegetables, fruit trees, flowers, grain, cotton, oil, etc. A special water-soluble fertilizer for crops. Due to the high price of water-soluble fertilizers, it has not been widely spread. The general consumption areas are mainly concentrated in greenhouse vegetable production bases, fruit tree production bases and some flowering areas, such as Liaoning, Hebei, Shandong, Xinjiang, Sichuan, Guangxi, Yunnan and Hainan are key consumption areas for water-soluble fertilizers. Due to the short growth cycle of vegetables and high economic benefits, consumers have high requirements on the quality of vegetables, and then the requirements of farmers for fertilizers are high. Water-soluble fertilizers have become the preferred fertilizer for vegetable farmers, and high-quality vegetables grown can sell at a good price. It brings high profits, so vegetables become the main consumers of water-soluble fertilizers. For field crops, because of their high cost, people are generally reluctant to invest, or only accept traditional fertilizer.
Compared with traditional superphosphate, granulated compound fertilizer and other varieties, water-soluble fertilizer has obvious advantages. It is a quick-acting fertilizer with good water solubility and no residue. It can be completely dissolved in water and can be directly absorbed and utilized by the roots and leaves of crops. The use of water and fertilizer, water and fertilizer, to achieve water and fertilizer integration, its effective absorption rate is more than double the common chemical fertilizer, reaching 80%-90%; and fast fertilizer efficiency, can solve the nutritional needs of high-yield crops in the rapid growth period . The water requirement of the drip irrigation system is only 30% of that of ordinary fertilizer, and the application of fertilizer can be done almost without labor, which greatly saves labor costs. More and more soil and fertilizer experts, agricultural technology extension experts, agricultural resource distributors and farmers have recognized the importance of water-soluble fertilizers.
Nowadays, water-soluble fertilizer is a new type of fertilizer. Compared with traditional fertilizers, it is not only rich in formula, but also 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. Application, through the leaf stomata into the interior of the plant to improve the absorption and utilization of fertilizer; also can 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 certain 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 fast-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, avoid the loss of fertilizer, that is, reduce the economic benefits of fertilization, and fail 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.
