"three wonderful tricks" of growing orchids and promoting flowers

As we all know, it is the unremitting efforts of every orchid friend to let the stamens be sent from time to time, and the pursuit of the delicate fragrance of orchids is our tenet of Yilan. But not all orchids can get what they want. some orchids often mention the problem of rare flowering of orchids. Of course, it is not that orchids can promote flowers no matter how they grow. Strong orchid seedlings are the basis for promoting flowers. Youdao is: weak seedlings do not send flowers, orchid flowers bloom by themselves! In order to make orchids comfortable and fragrant at the right time, we must do the following "three tricks".

First, increase the light.

Although orchids are negative-loving plants, sunlight is the energy factor of long leaves and buds. The sufficient accumulation of nutrients produced by photosynthesis is the prerequisite for flower bud germination. This is the truth of "more yang, better flowers" in Quran's works. The bluegrass that is well exposed to the sun must blossom first, and the flowers are full of fragrance. In order to make the orchid blossom in time, it is necessary to calculate the budding period according to the orchid species, so as to implement the plan to increase light and promote flowers. Generally speaking, the turn of summer and autumn is the season when the flower buds of most orchid species germinate. In addition to direct sunlight and shade, orchids should enjoy the sun as much as possible and accumulate enough energy reserves for budding flower buds. Otherwise, even if the pot is full of lush orchid grass, it is still not easy to sprout flowers, especially Huilan. Of course, pay attention to the new grass to avoid the sudden scorching sun, should be timely shade to protect the leaves. In contrast, because of the sun, the orchid on the outer balcony blossoms earlier than the orchid on the inner balcony. Therefore, it is necessary to arrange the orchid pots in the balcony or orchid room according to the budding period of all kinds of orchids, so that all kinds of orchids are evenly exposed to light, so that they all have the opportunity to give off buds and give off fragrance.

Second, control water dampness.

The growth of orchids is divided into two steps: vegetative growth and reproductive growth. Vegetative growth refers to the process of increasing the number of leaves, elongating and widening the shape of leaves, which requires a lot of water; reproductive growth refers to the process of germinating flower buds, blooming and fruiting, which requires less water, especially when flower buds are pregnant and petals bloom. Water must be controlled. In the vegetative growth stage, bluegrass grows tall and robust, and the new plant growth has been basically finalized, and the conditions of pre-flowering maturity and flower primordium accumulation are reached. At this time, the method of controlling watering is adopted to temporarily cut off the water supply and make the vegetative growth stop a little. Proper inhibition of its growth situation can promote the transition of bluegrass from vegetative growth to reproductive growth. Otherwise, bluegrass will often be immersed in the inertia of vegetative growth, which is why many bluegrass grow vigorously but do not blossom. The specific operation of water control should be determined according to weather conditions, plant structure and usual watering frequency. Generally speaking, it is good to double the usual watering interval for three consecutive times. In this way, it is expected to promote flower bud differentiation. As we all know, due to species constraints, it is not easy for Jian Lan Tiegu to blossom, and some orchid friends have not even seen it blossom for 10 years! However, as long as the orchid plant is strong, it is easy to succeed in promoting its flowering by controlling water. There is a basin of iron bone and silver needles that have not been seen for five years, but in the summer after the seedlings are strong, they will not be watered for a long time, leaving iron bone in a state of extreme thirst (don't be afraid that she is dying, her life is very hard)! After tossing her around enough, pour some water mixed with phosphorus and potassium fertilizer, so come every other week, two or three times later, this pot of iron bone silver needle which has not been spent for five years finally blossoms! And the flower fragrance period is long, the flower guard does not change! It turns out that when vegetative growth cannot be achieved after water control, bluegrass can achieve the continuation of life through reproductive growth. In fact, this method can not only promote the flowering of osteoporosis, but also suitable for other varieties to promote flower buds.

Third, suitable fertilization.

The internal factor of orchid flowering is that pseudobulbs accumulate and store enough organic nutrients, mainly phosphorus, hydrogen, oxygen and nitride, to provide flowering consumption. when the ratio of carbon to nitrogen in bluegrass is high, it is favorable for flowering. Therefore, the application of phosphorus and potassium fertilizer has become an important means to promote the flower bud formation of bluegrass. First, when bluegrass is on the pot, a small amount of superphosphate is mixed into the lower plant material as base fertilizer, which is an old orchid family's ability to promote Suxin Jianlan to blossom year after year. Second, the alum fertilizer water made by adding phosphorus and potassium fertilizer retting was applied in the bud stage of most bluegrass in late summer and early autumn, and the leaching solution of plant ash was poured occasionally. Third, 1/1000-fold solution of potassium dihydrogen phosphate was sprayed on the leaves during the bud period, and Huabao No. 3 was used as a special effect and high-phosphorus flowering formula, which was applied before flowering stage to promote flower bud formation, promote flowering and enhance flower color. Application after anthesis can also supplement the nutrient consumption of orchid flowering. Fourth, diluted blue fungus king and Gaocui are added when watering, which can also be used as a supplement to flowering fertilizer. It should be reminded that flower-promoting fertilizers must be carefully selected, and a considerable number of flower-promoting fertilizers contain hormones. According to some orchid friends, the flower-promoting effect of hormone flower fertilizer is very obvious, but in the second year, the growth condition of bluegrass is not ideal, the root is poor, the new seedlings are few, and the seedling condition is weak. Just like athletes who take stimulants, physical injury is inevitable.
