Raise orchids to feed these eight kinds of fertilizer to grow strong and fat.

Many flower friends raise orchids and feel that orchids can grow well without fertilization. In fact, no fertilizer orchids can grow well, that should be the origin of orchids. Orchids from the origin of the move to the home environment potted, grow strong, flowering beauty, and this "8 kinds of fertilizer" related, as long as the feed this "8 kinds of fertilizer", orchids can grow strong, grow fat.

From spring natural temperature rises above 16℃, until winter natural temperature drops below 16℃, for orchid vegetative growth period. During the vegetative growth period of orchids, thin liquid fertilizer for orchids is usually applied every 15 to 20 days. Spray foliar fertilizer once every 7 days. With orchids dedicated organic liquid fertilizer, diluted 500 times watering roots, 1000 times spray leaves can be.

In addition, orchid flower friends should focus on the three elements of fertilizer according to each growth period of orchids. Now introduce these 8 kinds. Those who don't understand should quickly understand them.

1, Su fertilizer

When the temperature starts to rise in spring, organic liquid fertilizer of 300~500 times liquid retting system is applied to promote the orchid plant to wake up from dormancy and enter the vegetative growth period as soon as possible.

2. Germination fertilizer

In 20 days after the fertilizer application, the natural temperature has stabilized above 16℃, flower friends can apply the same fertilizer as the fertilizer to promote early germination, more germination and strong germination.

3. Basic fertilizer for flower promotion

When the leaf buds of orchids extend out of the substrate surface about 2 cm high, there is a slow growth period of more than 20 days, which is the root growth period of new buds of orchids and the period of flower primordium formation of mother plants. The varieties that need to bloom can be irrigated with 500 times of special flowering fertilizer for orchids, or 1000 times of potassium dihydrogen phosphate, sprayed once every 5 days, continuously sprayed 3~4 times.

4, promote fertilizer

The fertilizer can promote the bud elongation, leaf development and growth of orchids. With proper fertilization, new plants can mature earlier and win the second tiller of the year. The fertilizer used is basically the same as the fertilizer used to promote Su. It is best to alternate application of inorganic fertilizer and organic fertilizer. It is usually sprayed once a week.

5. Cold resistant fertilizer

Generally, the north starts with the "cold dew" solar term and the south starts with the "frost" solar term. Nitrogen fertilizer is stopped and phosphorus and potassium fertilizer which can improve cold resistance are specially applied. Potassium dihydrogen phosphate can be used for pouring and spraying. Every 10~15 days into the water evenly sprayed once, continuously applied 2~3 times.

6, dowry fat

Dowry fertilizer refers to the application of a relatively balanced fertilizer of three elements to the orchid plant one week before the pot change and plant division, so that it can be transplanted with fertilizer to improve the survival rate and pot service of the plant on the pot.

7. Root promotion fertilizer

In the cultivation practice, we often encounter some descending seedlings, exotic seedlings, weak seedlings and seedlings with different pots. There are few or no healthy roots. If we do not take some measures to promote roots, promote its early rooting, its survival rate is naturally not high. Common organic liquid fertilizer for plants with 500 times solution, often used as root-promoting fertilizer, watered or sprayed as needed.

8, sitting on the moon fat

Sitting on the moon fertilizer is to compensate for the large amount of fertilizer consumed by orchid flowering. Because the flowering cost of orchid plants is quite large. If not given proper nutrition, it will not only make its premature aging, stress resistance weakened, until early death, but also affect the germination and flowering of the following year. Often used as sitting on the moon fertilizer is to apply 200 times the liquid retting organic liquid fertilizer.
