Advantages: A good water-soluble fertilizer has a complete ingredient formula and a large amount of content, unlike traditional fertilizers, which have a single element. Compared with water-soluble fertilizer, it can well meet the various nutrient requirements of crops. Water-soluble fertilizer products can carry out formula fertilization for different crops, etc. In addition, carbon water-soluble fertilizer contains nutrients such as large and micro elements required by crops, and the core ingredient "fuli micro carbon" is added. Solve the problem of crop carbon deficiency, provide carbon elements for crops, improve quality and yield, promote nutrient absorption, and improve soil compaction.
Two advantages, the amount of water-soluble fertilizer is less convenient, although the price of water-soluble fertilizer is more expensive than traditional large fertilizers, but the nutrient elements of water-soluble fertilizer are more, the nutrient element content is high, but the overall cost per mu is not high, the effect is also better, water-soluble fertilizer can be applied to an mu of 3-5 kilograms, which can save fertilizer, save costs, and easy to use.
1. Usage method
Spreading: spraying before irrigation, spraying after irrigation.
Flush application: Flush application with watering.
Drip irrigation: Fill through the fertilizer tank and apply with drip irrigation water.
Simple integration of water and fertilizer, using a fertilizer gun to inject water-soluble fertilizer solution into the soil of the root distribution area.
2. Problems in use
(1) Excessive use causes fertilizer damage. Acute fertilizer damage causes root burning, leaf margin curling, falling leaves, split skin, and blackening of branches and vine pith. Sometimes there is a chronic fertilizer injury phenomenon that the growth is good at the beginning of fertilization and then the growth is weakened. Chronic fertilizer injury sometimes shows black veins in the leaves.
(2) Improper use time: fertilization before germination, and it is more common to continue to apply high-nitrogen water-soluble fertilizer to the soil after August in autumn. It is easy to cause the loss of fertilizer and stimulate the growth of autumn shoots, resulting in waste and reduce the frost resistance of the tree.
(3) The ratio of fertilizer is unreasonable. The application of nitrogen fertilizer is heavy, the proportion of phosphorus and potassium fertilizer is low, especially the use of micro-fertilizer is insufficient.
(4) Only apply inorganic fertilizers, do not pay attention to the application of organic fertilizers. At present, fertilization only considers crop nutrition, not soil needs. Water-soluble hypertrophy is mostly soluble compounds, and in the long run, soil organic matter is excessively consumed (especially in the case of heavy application of nitrogen fertilizer), and useless inorganic ions are retained, resulting in soil salinization.
