How can we make orchids have the best opening products? (repost)

I. selection of species

General traditional varieties as far as possible to a reputable Orchid Garden or friends to punish. The grass of stalls and wandering orchid vendors is either fake or sick, and the insurance coefficient is too low.

1. To select new seedlings that want to be strong, of course the price of the former ridge grass is not low, but after two years of cultivation, we will know whether it is cost-effective or not. This is especially true for friends who are newly raised orchids. Good seedlings are easy to raise, strong resistance, easy to germinate and good management. If two or three seedlings are introduced in spring, they will have a doubling effect in autumn.

2. Focus on making the grass strong. Healthy and sturdy plants are the basis of its flowers and arrows. The flowering of spring orchid consumes a lot of nutrients, and it is impossible to produce good flowers due to congenital deficiency of nutrition. As the saying goes, only seedlings can spend well.

Second, bud maintenance and bud thinning

1. Protection of flower bud

If there are many seedlings, there will be flowers. After the orchid budding, watering should be very careful, the pot soil should not be too wet, so it is easy to have rotten roots and cause the bud to rot under the action of germs. Therefore, each watering should be less than usual, in order to avoid water shortage in the lower part. The method of half-height soaking basin can be used. When watering, if the water is splashed on the bud, it should be ventilated in time to avoid mildew.

2. Pull out the scape management pass

Once the bud begins to wake up, jointing and growing, the flowerpot should be moved into the room. The purpose of this: to ensure that the color of orchids is bright green, with the exception of yellow and red flowers. At the same time watering is in the first place, try to keep the orchid basin moist, the basin surface is not too dry, the environmental humidity is at least more than 50%, laying the foundation for the graceful orchid.

3. Flowering maintenance pass

In order to get the best opening of flowers, the key is to master watering. When the small mouth of the bud is first released, most petal flowers need to implement water control to prevent the side petals from elongating and sagging; wrinkled petal flowers should be watered relatively more to make them dynamic and elegant; strange flowers need more water, and it is better to basically reach the state of wet leach.

4. Shu Lei

The nutrition demand of orchid bud grass is very big, generally 5 seedling grass spring orchid has a flower bud on it. It is enough to leave three or four buds in a potted flower. Pay attention to the time of thinning buds around the end of November, the Autumn Equinox will get up early and waste nutrients in the evening.

Generally speaking, for spring orchids with less than ten seedlings in each pot, it is best to leave only two buds and one below five seedlings. When the stem is budding, the flower will be weak and strong according to the height of the flower stem. For example, the weak orchid seedlings, the diseased seedlings and the buds that rose only in late autumn should be removed. There is only one strong and full bud in the back ridge, such as there is also a bud in the front dragon, so it is appropriate to keep the front dragon bud. If there is any skew and weaker buds are also removed.

To pick flowers, you have to wait until there are three things to stay:

1. The new grass blossoms in that year.

2. No flowers from Reed head for more than two years

3. Leave more than one flower for each gourd.

III. Vernalization

The so-called vernalization refers to the low temperature stage that Lanhui must go through during the period of reproductive growth, which plays an irreplaceable role in promoting the growth of flower buds. The degree of vernalization is related to the quality of Lanhui's products. Vernalization is the lowest period of air humidity and soil moisture of orchids in nature.

All previous dynasties of Yilan attached great importance to the full vernalization of Chunlan. It is suggested that in winter, especially during the period from heavy snow to Greater Cold, orchids should be kept at a low temperature of 0: 10 ℃, and the temperature difference between day and night should be kept at about 10 ℃, so as to accumulate sufficient nutrients and prepare for flower arrows to bloom after spring. Full vernalization, temperature difference should be appropriate is a necessary condition to promote Chunlan flowers and arrows in place, and fully comply with the natural characteristics of Chunlan flowering. There is not enough vernalization during the pregnancy bud, and there is not enough relative humidity when pulling the scape. If you force it to open it, it will be hasty and impatient, and the opening product will be greatly discounted.

Chunlan generally takes nearly half a year from budding after autumn to flowering after spring. in the process of long-term natural evolution, Chunlan has formed the characteristic that only through the low temperature vernalization in winter can the flower bud expand and the arrow rise; in the period of reproductive growth, if the temperature is on the high side, it is easy to borrow the spring blooming phenomenon, the flowers are covered in the potted noodles, and the flowers are greatly discounted, which seriously affects its ornamental ability.

In this regard, we should pay attention to three problems:

1. Vernalization should be sufficient. Generally speaking, the period from Lesser Snow to Greater Cold is the best vernalization period for Lan Hui. the temperature of this period had better be controlled at 12 °, and the vernalization time should not be less than one month, especially from the Winter Solstice to Greater Cold.

2. The temperature should not be too high or too low during vernalization. In the vernalization stage, the temperature must not fluctuate too much. The low temperature below-5 °and the temperature higher than 15 °are not conducive to the normal growth of flower buds, which can easily lead to stiff buds and affect the uplift of scape. Chunlan often appears the phenomenon of spring blooming, which greatly discounts the flowers.

3. Avoid excessive humidity during vernalization. Vernalization is the lowest period of air humidity and soil moisture of orchids in nature. The ecological environment of orchids in nature is the direction of our indoor orchid cultivation. Therefore, the air humidity and basin soil humidity in vernalization stage should not be too high, otherwise it is easy to rot buds and roots, which is not conducive to the growth of Lanhui in the coming year. Practice has proved that low-temperature vernalization is an insurmountable stage for the reproductive growth of Orchid, and we can not change it artificially against the laws of nature, otherwise, it will directly affect the opening of orchids.

Fourth, humidity, light

The main results are as follows: 1. The high humidity in flowering season is the catalyst to ensure the elevation of spring orchid arrows. Chunlan keeps a high relative humidity in the air during blooming season, which is very beneficial to the uplift of flowers and arrows. Lanyou can take a variety of measures such as humidifier humidification, basin water spraying, ground water spraying, flume humidification and other measures to create an air relative humidity of not less than 50%, which can effectively improve the flower and arrow height of the orchid, especially the lotus petal orchid.

2. Proper light should be given during the bud period to make it earn enough nutrients and be ready to go. Pay attention to the light can not be too strong, strong bad bracts, weak flowers without God. (except for colored flowers)

5. Use fertilizer

Generally, potassium nitrate, potassium dihydrogen phosphate, Huabao No. 3 or borax can be used about half a month before flowering. There is a large amount of nutrition consumption after flowering, so it is better to supplement nutrition to orchid plants about ten days after flowering with all-element organic fertilizer.
