What is the performance of orchid?

Speaking of fertilization, people often mention the words of nitrogen phosphorus, but fertilizer far does not only have these, but also magnesium, copper, manganese, calcium, iron, zinc, copper, boron, etc., each element is lacking, The symptoms of orchids are different, let’s take a look!

Orchid deficiency

Nitrogen elements are mainly to promote the growth of leaves. When the nitrogen element is lacking, the new leaf is obviously growing, thinner than the old leaves, and the leaves are yellowish, lack of gloss.

Workaround: Potassium sulfate is used to pelgium, or spray the blade with urea solution in the evening, 3 to 5 days, continuous spraying 3 times, the new leaf will slowly return to normal.

Orchid deficiency performance

Phosphorus is accompanied by promoting the growth of the bud. When the blue plant lacks phosphate fertilizer, the growth of the buds is slow, and the lack is not long, and the leaves will be curled.

Workaround: Select the potassium phosphate leaching solution, 10 days, 2 times. Or spray the foliage fertilizer, 3 to 5 days, and then spray 3 times.

The performance of molan deficiency

The lack of magnesium elements, and the phenomenon of yellow leaves will occur. Especially the old leaves, the portion of the leaf tip and the leaves will appear yellow, and the leaves are curled.

Workaround: A 0.5% magnesium sulfate solution can be used in the evening, spray once every three five days, and it can be corrected for three five times.


The larch lack of potassium is yellowed and the leaves are yellow, and the old leaves are yellow, and slowly spread to the new leaves and gradually become brown by yellow. And the plants are relatively soft, easy to bend. If you encounter strong light or low temperature, the leaves will dewate.

Solution: You can take a 0.5% potassium sulfate solution to pour the roll, and the gray can also be revoked.

Orchid deficiency

If the lack of manganese or manganese is easy to be bothered, although there is a shade, it will still have a sungage spot on the blade, the spot is also spotted, and the flower bud is not developed. Neutral, lime, and sandy soil, it is more likely to appear manganese symptoms.

Workaround: Select 0.3% of manganese sulfate solution to spray the blades 3 times, it can be corrected.

Orchid deficiency

Orchid deficiency is presented as a hook shape, which is severely affected.

Workaround: A 1.0% lime solution can be taken rounded once, or a 3% solution of a calcium powder can be used once, and it can be corrected.

The performance of the orchid lack of iron

Orchid deficiency is mainly manifested for young leaves, showing yellow white, causing pulse and leaf tips in the middle.

Workaround: The blade can be sprayed with 0.5% ferrous sulfate solution, 3 days, and then sprayed two or three times, it can be corrected.

Orchid lack of zinc performance

Orchid lack zinc is mainly manifested with rust spots in the middle of the vanes, and gradually expands both ends, and the petiole of the new leaves has a significant difference between the old leaves.

Performance of blue lack of copper

The lack of copper elements of the orchid is mainly manifested as the pip scrub. It turns into a grayish white, and gradually expands to all leaves, and the growth is gradually stagnant.

Solution: It can be applied with 0.2% sulfate solution, once every 7 days, and then spray twice, it can be corrected.

Performance of a larch latch

The blue larch is characterized by the injury of the young leaves, and the leafle ring is extremely brittle. The flower buds are slow, and the number of flowers is significantly reduced, and the growth of the plants after flowering is weak.

Solution: A 0.3% boron or boric acid solution can be applied, once a week, and then spray 3 times, it can be corrected.

Orchid deficiency

The lack of molybdenum is a new plant will also be clearly dwarf, and it is not high; the old leaves lose green, so that the yellow, wilting to necrosis.
