In the process of traditional agricultural farming in China, farmers have the habit of supplying various nutrients to crops along with natural rainfall or irrigation. However, due to the uncertainty of the amount of water used, the nutrient content of the fertilizer used is low, the composition is single, and the water solubility is poor. As a result, the flushing effect is not ideal. For example, if the local nutrient concentration is high, the seedlings will be burned and the nutrient concentration in the place far away from the water source will be too low and there will be no fertilizer effect. Although there are some disadvantages in fertilizing the fertiliser, it also has its own advantages. For example, the raw materials suitable for fertilization are generally water-soluble, the nutrients are not easily solidified by the soil, the soil is not compacted, the plants are easily absorbed, and the fertility manifests quickly. Toxic residues. In addition, today's flushing and fertilizing generally belongs to compound fertilizers containing a variety of nutrients, which is very much in line with the future direction of fertilizer development and the demand for the development of modern agriculture intensification. Therefore, in recent years, fertilizer manufacturers across the country have developed fertilization as a separate fertilizer species, carried out large-scale promotion and application, and achieved good economic and social benefits. The following is a brief introduction to the current type and application of fertigation on the market, for farmers to have a preliminary understanding of this and the right purchase. First of all, flushing and fertilizing are mainly divided into physical barrels and solid powder bags. From the chemical properties of fertilizers and intrinsic nutrients, they are mainly divided into three types: one is organic type, such as amino acid type, humic acid and marine biological type, and the other is inorganic type, such as potassium dihydrogen phosphate type and high calcium concentration. Potassium type, etc.; one is a microbe type, such as light full-bacterial type, enzyme type. In addition, there is a new type of fertilization that is scientifically processed and compounded with organic, inorganic, biological and other raw materials on the market. It belongs to compound preparations and is produced by Beijing Oasis Star Technology Co., Ltd. Fertilization is such a thing. From the application scope, the nutritional requirements for different crops can be divided into broad-spectrum, vegetable-specific, fruit-tree-specific and special-purpose cash crop-specific. Fertilizer application has the characteristics of simple use, rapid fertilizer effect, etc. Therefore, it is generally applied as a topdressing variety during the crop growth period in the practical application process. Mainly in some economic crops such as various vegetables, fruit trees and other long-term or large-scale results of the need for nutrients for a long time. At this time, if ordinary fertilizers are used, nutrient release and conversion will be slow and fertilizer efficiency will be slow, which will inevitably affect the yield and quality. Especially in winter greenhouse cultivation crops, because of the disadvantageous conditions such as low temperature, lack of sunshine, etc., choose a quality and reliable fertilization application, the effect is very good. How do you apply red fertilization? Some peasant friends feel that flushing and fertilization is to flush with water! In fact, this is a wrong understanding. The principles of fertigation and application of other fertilizers are the same, but also deep and concentrated applications. For some shallow-rooted leafy crops or crops that are inconvenient for top-dressing operations, they can be flushed with water, but the amount of water that must be controlled must not be excessively high to promote uniform nutrient distribution. However, some deep-rooted crops such as cucumbers, tomatoes and fruit trees should be planted or applied in a cave. Before application, the fertilization can be diluted to a certain multiple, evenly distributed into previously dug trenches or holes, and then a small amount of water can be poured. . What precautions do you have during the application of fertigation? First of all, according to the soil fertility, the amount of base fertilizer, and the characteristics of the required fertilizer to be planted in their own cultivation areas, determine the appropriate fertilization varieties. Then, read the instruction manual of the flushing fertilizer you purchased and master the appropriate fertilization period, application amount, and application method. You must not make your own decisions based on previous fertilization experience to avoid unnecessary losses.
