Fertilizer is very important for the growth of vegetables, then not all fertilizers can be applied on the fertilizer application of vegetables. Let's take a look at examples of what “spices†need attention.
The planted peppers are poorly grown and the leaves are wilting, but not due to disease. What is the cause of this? After careful understanding of the master Wang's production operations, it was concluded that the application of potassium chloride compound fertilizer was causing the scourge.
Potassium chloride-based compound fertilizers are mostly used in field crops. Will they be used in peppers? Originally, I don't know that peppers belong to the crop of chlorine crops. I think that when the ginger was planted last year, most of the potassium chloride compound fertilizer remained in the bag. So when the pepper was fertilized, these fertilizers were applied to the fertilizer, resulting in poor growth of the peppers. If the vegetable grower applies potassium chloride compound fertilizer during the pepper growth process, it will cause three hazards:
First, chloride ions combine with calcium ions in the soil to produce calcium chloride. The calcium chloride solubility is large, easy to loss with water, causing calcium deficiency caused by pepper causes serious umbilical rot. At the same time, calcium is an indispensable element in the formation of soil structure. Excessive loss of calcium salts can also damage the soil structure and cause compaction.
Second, chloride ions in fertilizers are likely to activate aluminum, manganese, and other metal elements in the soil, resulting in excessive absorption of peppers, resulting in poisoning and affecting the growth of peppers.
Once again, chloride ions cause the soil to become acid and inhibit the activity of beneficial microorganisms in the soil, creating conditions for the invasion of pathogens.
Therefore, to remind farmers to use fertilizer, we must first understand whether the vegetables are bogey chlorine, like melon, watermelon, cabbage, pepper, potatoes, lettuce, leeks and other bogey crops can not use potassium chloride compound fertilizer, but should use sulfuric acid Potassium-based compound fertilizers prevent chlorine ions from harming these vegetables.
