Several fertilizers commonly used in flower planting

Choosing a suitable fertilizer in the planting of flowers can get a good profit. Flower growers should adopt reasonable fertilization schemes according to the law of fertilizer demand and soil properties of flowers. Here are several kinds of fertilizers commonly used in flower cultivation.

:

The content of trace elements in soil is generally enough for plants to use for a long time, and the supply of trace elements is insufficient, mostly due to the lack of available amount due to the influence of soil conditions. In general, the symptoms of lack of trace elements are first shown in the new tissue, the application of trace element fertilizer must be carried out on the basis of reliable diagnosis, the application concentration should be cautious, excessive may lead to side effects such as seedling poisoning.

Ammonium nitrate, white crystal soluble in water, strong hygroscopicity, dry after water to form a lump. The ammonium nitrogen in ammonium nitrate is easy to volatilize and lose, so it is necessary to cover the soil deeply as topdressing. The stick that has been hygroscopically agglomerated can be smashed gently, not with a hammer to avoid accidental explosion. Ammonium nitrate is flammable and easy to explode at high temperature, so it can not be put together with combustible materials during storage and transportation. It is not used as base fertilizer, nor should it be used as seed fertilizer, because it is easy to absorb water, dissolve and adhere to the seeds, affecting seed germination.

Ammonium sulfate can be used as base fertilizer, seed fertilizer and topdressing, but it can be used as topdressing in humid areas. If combined with ammonium bicarbonate, such as ammonium bicarbonate as base fertilizer and ammonium sulfate as topdressing fertilizer, the fertilizer efficiency can be improved. It is not suitable for continuous and single application in large quantities, but should be applied in combination with other nitrogen fertilizer varieties.

Urea is a high concentration of solid nitrogen fertilizer, which is easily soluble in water. After urea is applied to human soil, it must be transformed into ammonium bicarbonate by microorganisms before it can be absorbed and utilized by plants. The transformation rate is related to temperature and soil moisture. It usually takes about a week in spring and autumn and 2-3 days in summer. In order to prevent the loss of ammonia, urea should be applied deeply to cover the soil.

Ammonium bicarbonate, the product of urea conversion, can make the soil solution show temporary alkalinity. Therefore, the application of urea in the nursery should be cautious, especially for the seedlings of coniferous species. Urea is generally not suitable for seed fertilizer, but can be used as base fertilizer and topdressing, especially for topdressing. If the alkalinity is too high, it will have a certain toxic effect on seeds and seedlings. It is appropriate to apply fertilizer outside the root, spray and spray fertilizer in the morning and evening when the atmosphere is humid and dewy.

The commonly used zinc fertilizer is zinc sulfate, which is soluble in water. Zinc fertilizer can be used as base fertilizer, seed fertilizer and topdressing fertilizer, mixed with physiological acid fertilizer and applied deeply near the root system. Toxic, can be used as a pesticide, commonly used copper fertilizer is copper sulfate, blue crystal, soluble in water, copper sulfate as base fertilizer.
