Essentials of fertilization in "five stages" of Orchid Plant

1. Sprouting period: nitrogen fertilizer was diluted in proportion and then diluted 10 times, so that there was fertilizer for each watering, and phosphorus and potassium fertilizer was sprayed 5 times per month for 6 times. Ensure that the orchid plant will be fertilized in time after awakening, so as to lay a good foundation for the emergence of the orchid plant. Fertilizing should be diligent and light.

2. Spring growth period: when the lowest temperature reaches more than 12 degrees Celsius, nitrogen and potassium fertilizer are diluted in proportion and then irrigated once, which promotes the mother plant to divide rapidly and differentiate new buds. This period is the golden season for the growth of orchid plants. Timely fertilization is very important in a year's production. Do not apply too much fertilizer to damage orchid plants, but should strictly reduce fertilization in accordance with the instructions. Self-made cake fertilizer had better be used after experimental observation, and do not act in haste. Because the content of this kind of fertilizer is not accurate, it is easy to cause losses. Generally dilution of 500 times will not be a problem (not absolutely). With the gradual increase of air temperature, the new buds expanded rapidly, supplemented by phosphate fertilizer. Daylighting as far as possible, give full play to the physiological function of the plant, quickly absorb and convert fertility, carefully observe plant growth after fertilization, and find that fertilizer damage should be irrigated or turned over in time.

3. The peak growth period in spring: as soon as we apply root fertilizer proportionally, most of the plants still contain some residual fertility, so it is not suitable to apply fertilizer deliberately. It is only necessary to apply it according to the proportion of 1cm and 8 times combined with watering. Spraying foliar fertilizer once every 3 days does not hinder the normal growth and development of the orchid plant, and pure coarse material can supplement the root fertilizer once.

4. Stagnation period. During this period of time, due to the high temperature, most orchid plants stagnated, even if the new seedlings grew very slowly, and the father grass was pregnant with flower buds at this time, so it is still necessary to spray some phosphate fertilizer to promote the father grass to flower.

5. The growth is exuberant in autumn, during this period, the new buds basically grow into seedlings, and a few are semi-mature seedlings, all of them can grow into big grass and strong seedlings in autumn, the flower buds of father grass are basically unearthed, and a few new strong seedlings appear occasionally. Those who have flower buds should stop applying root fertilizer, foliar fertilizer should be halved as appropriate, and non-flower orchid plants can be proportionally irrigated with phosphorus and potassium fertilizer once to ensure that the new Reed head is huge in that year, and there is no hope of blooming next year.

6. Orchid plants basically stop growing during hibernation, and orchid plants maintained on the balcony and indoors still need a small amount of foliar fertilizer, which is mainly phosphorus and potassium fertilizer 3 times a month, and is sprayed at noon in sunny weather. (song Mingyuan)
