The most annoying thing about planting crops is that crops are deficient, once the crop is deficient, it will directly affect the growth of crops, and the lack of nutrients can easily lead to crop nutrient imbalance, so how to supplement trace elements to crops according to needs has become a particularly important thing.
What does the lack of different elements lead to?
If the crop is short of nitrogen, it will directly inhibit the growth of the crop, the old leaves will turn yellow, the new leaves will become thinner, and the root system will flower late. Phosphorus deficiency in the main root will be very weak, and the seed grain will be particularly small. If the potassium fertilizer is missing, the crop will grow slowly, the old leaves will dry up, and all kinds of deformed fruits will appear. If the plant is deficient in zinc, the plant is short and grows slowly. Boron deficiency can lead to the death of the hollow root tip of the block. Magnesium-deficient plants will turn yellow in the later stages.
What are the roles of several important trace elements?
Nitrogen is used as a living element, because nitrogen is the main component of proteins, phospholipids and nucleic acids, affecting plant physiological activities and growth and development. Nitrogen is the main component of protoplasm and biofilm, and it is also a component of chlorophyll, which plays a very important role in regulating crop life activities.
The content of phosphorus in the plant body is second only to nitrogen fertilizer and potassium fertilizer, generally in the seed content is relatively high, phosphate fertilizer is very important for plant nutrition, phosphorus elements involved in crop photosynthesis, respiration, energy storage, etc., are helpful.
Potassium is the main nutrient element of crops, but also the most easily missing elements in the soil, potassium can effectively promote the photosynthesis of crops, potassium deficiency will directly lead to the attenuation of photosynthesis, potassium can significantly improve the plant's like search and use of nitrogen, quickly converted into protein, promote plant growth.
