How to raise cold orchids before they bloom
A little life knowledge will introduce you to how to raise cold orchids before they bloom and the key points of cultivating thin leaf cold orchids. Next, I will let you understand them together.
The microclimate in which cold orchids grow has the characteristics of high average temperature, long frost-free period, no direct sunlight, high precipitation, and high air humidity. The temperature in winter is also relatively high, and there is little interference from snow, freezing or frost. Because the soil layer of the orchid is thick and grows in the dead leaf forest on the hillside, even when the rainy season comes, there will be no water, and the soil is loose and breathable, which is very conducive to the elongation of orchid roots. It can be observed from the natural ecology of cold orchids that the growth environment in which cold orchids are located is much superior to the ecological environment of other orchids such as Cymbidium. Therefore, it is more difficult to cultivate cold orchids than other types of orchids.
The flowering period of cold orchids is generally from November at the end of the year to February of the following year. Its flowering period is about 30 to 40 days, and some even last as long as 50 days. More than 10 flowers are bloomed, which consumes a lot of nutrients and accelerates leaf aging. Cold orchids bloom easier than spring cymbids, and flowers bloom almost every year, which is a way to make up for the slow asexual reproduction of cold orchids. However, this compensation caused the new shoots to not sprout, but the old seedlings to begin to fail. Therefore, the high requirements for environmental conditions and the weak growth of Hanchids have made it more difficult for private planting.
So, what are the reasons why it is difficult to cultivate cold orchids? How can families grow cold orchids well? What aspects of maintenance issues need to be paid attention to? This is the focus of raising Hanchids well, and it is also a topic that many orchid friends who like Hanchids pay close attention to. Let's analyze with our orchid friends, what are the difficulties in cultivating Handicrafts? How can we raise Hanlan well? I hope to inspire and help Lan friends.
Analysis of the reasons why the cultivation of cold orchids is difficult: In the interspecific hybridization of original ecological orchids, most of them involve cold orchids, so they are divided into "spring cold orchids, summer cold orchids, autumn cold orchids and winter cold orchids". Winter cold orchids, also known as pure-bred cold orchids, have small false bulbs; while spring cold orchids, summer cold orchids, and autumn cold orchids are the products of natural hybridization between orchids, with large false bulbs, especially autumn cold orchids. The main reason why purebred Hanchids are difficult to cultivate during family breeding is that the false bulbs are small and the stored nutrients are not much. However, there are many leaves, easy flowering, and large consumption of nutrients, which will inevitably lead to insufficient supply of nutrients, resulting in relatively weak growth., plants age faster.
Experience in breeding Hanchids has proved that nine out of ten pure-bred Hanchids with weak growth are caused by root rot. Therefore, if you want to raise Hanchids well, you should first start by cultivating the roots. Family-bred orchid is difficult to cultivate due to the limitations of the environment and plant materials. There are mainly the following five aspects that orchid friends need to take seriously to avoid.
1) In a humid environment, the leaves of orchid with poor ventilation are thin and wide, which requires high air humidity in the maintenance environment. The air humidity should be maintained at around 80%, which is conducive to its growth and development. However, if ventilation is not good in a humid environment, pests and diseases such as scale insects and black spot are prone to occur. However, good ventilation is not conducive to moisturizing. Therefore, it should be flexibly controlled according to specific circumstances.
Solution: Place the orchid basin in an environment with good ventilation and high humidity for maintenance. If conditions permit, a reservoir should be established to increase humidity, or a humidifier should be used to increase the air humidity of the environment; at the same time, when the temperature is high, Open the doors and windows more for ventilation; in winter, the fan should be turned on at the right time for ventilation, which is a necessary condition for maintaining the orchid.
2) Temperature and light factors affect the creation of a suitable environment for growth, which is an important aspect of maintaining cold orchids. Too low or too high temperatures and too strong sunlight are not conducive to the growth and development of Hanchids. The most suitable temperature for the growth of cold orchids is between 20 and 25 degrees; when the temperature is 5 degrees or below, frostbite can easily occur, causing long saucy red spots on the leaves. In severe cases, the leaves can suffer frostbite or the entire plant will be frozen to death; When the temperature exceeds 30 degrees, if it is exposed to direct sunlight, the leaves will be burned and the leaves will be scorched.
The solution: Cold orchids like shade, but also need sunshine. More mild sunshine should be given to make the color of cold orchids more vivid and the leaves crisp and thick. Therefore, from the beginning of November in winter to mid-May in early spring, it can be allowed to shine more in the sun, especially in the morning and evening; when the summer temperature is high, a double sunshade net should be pulled in time to provide shade maintenance to avoid the scorching sun. Burn leaves; in late September in autumn, when the flower buds of cold orchid differentiate into flowering period, it is advisable to give sunshine before 9 a.m. and after 16 p.m.
3) The main reason for the failure of breeding orchid caused by improper watering is improper watering. Therefore, special attention needs to be paid to the control of watering. The root system of cold orchids is relatively developed and has strong drought resistance. It is better to have a slightly moist and slightly dry plant material, which is conducive to the breathing and breathability of the roots; during daily maintenance, carefully observe the dry and wet conditions of the orchids before watering. Avoid watering too much, causing water accumulation in the roots and hypoxia and rot.
Solution: When checking the water content of the plant materials, you can tap the orchid basin with your hand by tapping the basin method. If the sound is dull, it means that the water content is high; if a crisp "dong" sound is made, it means that the orchid basin is short of water. You can tap the basin with your fingers along the wall of the basin and tap from the upper part of the basin to the bottom. You can also tap the basin with a small wooden stick. You can master the essentials by trying a few more times. Generally speaking, the amount of watering for cold orchids should be relatively less than that for orchid varieties such as Jianlan, and the number of watering times should be reduced to half that of other orchids.
4) Improper fertilization causes poor growth. Cold orchid is like orchid varieties such as Cymbidium and Jianlan. It requires thin fertilizer application and careful application, and avoid damaging seedlings by applying strong fertilizer; because the flowering period of cold orchid is long, it consumes a large amount of nutrients, and it needs to be replenished in a timely manner to promote it to regain vitality as soon as possible. Therefore, whether fertilization is appropriate is another major reason that affects the success or failure of cold orchid breeding.
Solution: During daily maintenance, in addition to appropriately applying ripe organic fertilizer liquid according to the growth situation, during the growth period of cold orchid, 0.1% potassium dihydrogen phosphate should be sprayed on the leaves once at intervals of about 10 to 15 days to promote growth and enhance stress resistance; but spraying foliar fertilizers should be stopped in summer to avoid causing leaf fertilizer injuries; in the case of good growth, topdressing foliar fertilizers should be reduced. After about 10 days after the orchids wither and the recovery period of the cold orchids, use 1 vial of vitamin B12, each vial with 5000 grams of diluent with water to irrigate the roots, which can promote their rejuvenation.
5) Excessive consumption of nutrients is easy to age, which is one of its physiological characteristics. Cold orchids bloom relatively easily. As long as there are more than 2 tubes of grass seedlings, they can sprout flower buds, and sometimes even 2 to 3 stalks of flowers can sprout. Therefore, flower bud formation consumes more nutrients than leaf buds.
Solution: Leave fewer flower buds, reduce nutrient consumption, and delay aging. Properly removing weak flower buds can not only reduce excessive consumption of nutrients, but also facilitate the formation and healthy development of leaf buds, so as to delay the premature failure of old orchid seedlings and achieve the goal of increasing the number of seedlings, continuously expanding the population, and growing vigorously.
How to raise cold orchids before they bloom
If you want to raise Hanchids well, you should choose suitable plants for its growth and choose good cultivation plants. This is one of the most critical factors in cultivating Hanchids well. Based on the growth characteristics of small pseudo-bulbs, less accumulated and stored nutrients, more leaves, and ease of flowering, it is best to select the cultivation materials: humus soil rich in organic matter, high degree of decomposition, coarse particles, and high nutrient content., plus coarse grain planting materials with high drainage: such as gravel, red brick particles, plant gold, pottery particles, etc., it is ideal to cultivate orchid.
The selection ratio of orchid plant materials is: 40% humus soil, 20% chaff charcoal, 20% epiphyte gold, 10% dried cow dung, and 10% bone charcoal; or 40% mushroom soil, 20% rice hull charcoal, 20% red brick granules, 10% dried cow dung, and 10% bone charcoal.
Lentinus edodes soil is the waste bacterial material used to cultivate Lentinus edodes. It is rich in nutrients and loose and breathable, which is conducive to the growth of root systems and probiotics; dry cow dung is suitable for the feces excreted by the hay eaten by cattle in winter, because the hay passes through cattle rumination. After the plant fiber is finely divided, it is still elastic and contains nutrients. This cow dung is loose, soft and fertile after being soaked in water, which is very suitable for the growth of the root system of Hanchids.
Bone charcoal is rich in phosphorus and potassium, which is gentle in fertility and long-lasting in effect, making the plant material loose and breathable; rice chaff charcoal is a dark brown rice bran that has not been completely burned out, which contains potassium element. When added to the cultivation plant material, it is more conducive to loosening and can also increase the temperature of the plant material. These plant materials are sourced from various rural areas, which are relatively convenient to obtain materials and have very low cost.
Cold orchids should be planted in multiple clusters together. Choosing large pots for planting is good orchid, which has the characteristics of multiple clusters and growing vigorously. Cold orchids are no exception. When cultivating purebred cold orchids at home, if 6 - 8 seedlings or 8 - 10 seedlings are planted in multiple clusters, the root system of cold orchids will be more developed and the growth will be more robust. Especially if multiple seedlings are planted together, when choosing orchid pots, you must choose a large pot to plant them, which is more conducive to their growth.
You can use purple sand pots with a diameter of 18 - 20 cm and a depth of 15 - 20 cm. Plant 8 to 10 seedlings in each pot. Breeding practice has proved that appropriately increasing the number and density of planted seedlings of Cymbidium chinensis is conducive to its growth, flowering and germination rate. When planting in the pot, in principle, the roots are not rotted, so do not prune them. Let the orchid roots stretch and place them into the orchid pot. Fill the plant material (the plant material should be wetted in advance, but it is advisable not to run water), and beat the orchid pot to make the plant material fully fit tightly with the orchid roots; cover the plant material to 2/3 of the false bulbs, and do not bury the plant material too deep to avoid affecting the smooth breathing of the orchid roots and false bulbs; After planting, it should be placed in a shaded ventilated place to slow down for 5 to 7 days, and then poured once to penetrate through water. After the orchids are put into the basin, then go to normal maintenance.
