As a new type of fertilizer, what are the application principles and methods of water-soluble fertilizer?

As a new type of fertilizer, water-soluble fertilizer, compared with traditional fertilizer, not only has many secret recipes, but also has a very flexible way of use. In recent years, it has developed rapidly in China, which conforms to the characteristics of uninterrupted digestion and absorption of nutrients by green plant roots and can reduce the leaching damage caused by a large number of one-time fertilization. Let's share with you the application principles and methods of water-soluble fertilizers.

1, fertilization standard The most important fertilization standard for water-soluble fertilizers is a small amount of meals. This is because the roots of green plants have the characteristic of uninterrupted digestion and absorption of nutrients, so it is necessary to reduce one-time fertilization, because one-time fertilization will cause harm to green plants and destroy data. Water-soluble fertilizers are generally used by spraying, irrigation or sprinkler irrigation equipment, especially under the standard of drip irrigation, the growth and development of roots are relatively complete, and the dependence on soil nutrient supply is reduced at this time, which depends largely on the nutrients given by drip irrigation. There are more regulations on the effective proportion and concentration of nutrients. If the secret recipe is unbalanced, it will endanger the growth and development of crops.

2. Effective irrigation As far as drip irrigation is concerned, it is generally enough to keep the deep root layer moist. The root depth varies greatly according to different crops. You can dig the soil layer with a shovel anytime and anywhere to master the actual deep root layer. Excessive irrigation will not only lead to water consumption, but more seriously, nutrients will penetrate below the root layer, consume fertilizers and limit crop yield. Especially urea solution and nitrate nitrogen fertilizer are easy to flow out with water. According to the use of other fertilizers, water-soluble fertilizers are generally only used for fertilization and do not need to be replaced. It is necessary to mix reasonably, reduce the cost of fertilizers and give full play to the advantages of various fertilizers.

3. Common problems in fertilization by drip irrigation first, drip irrigation with cold water first, and then gradually fertilize after the pipeline is filled with water. Immediately after fertilization, drip irrigation with cold water for 20-30 minutes to discharge all the residual fertilizer liquid in the pipeline. Secondly, long-term use of drip irrigation fertilization in greenhouse or ambient temperature will lead to nutrient accumulation on the ground and endanger the growth and development of roots. Drip irrigation under film can be used to inhibit the surface transfer of salt. In addition, pay attention to the uniformity of fertilization. In general, the slower the fertilization, the better. Especially for the elements that are not easy to move in the soil, increasing fertilization time can greatly improve the utilization rate of the nutrients that are not easy to move.
