Cuttings of Gypsophila paniculata should be carried out between late August and late April, and lateral buds without pests and diseases should be cut from good mother plants. Cut the bottom leaves, keep the top 3-4 pairs of leaves, dip them in indolebutyric acid and insert them into the soil. After cutting, shade should be carried out, and temperature control should be paid attention to, about 20 C, almost a month of cultivation time, branches will grow new roots.
1. What does orchid sprout look like
< p style = "text-align: left;" > When an orchid sprouts, first determine whether it is a leaf bud or a flower bud.The leaf buds of orchids will pull out the leaves later, so it will feel harder, and the leaf buds usually grow on the pseudobulb.The sheath of the leaf bud is usually thicker and more elongated.The flower bud is softer to the touch because it grows out of the bud later. It usually grows on an old but strong pseudobulb.< span > The sheath of the flower bud should be thin and dry, and it looks round and bulging, generally with a bulging middle and a pointed head.However, sometimes, the germination of leaf buds and flower buds has a certain time difference, such as in spring, the leaf buds of Jianlan will germinate earlier than the flower buds.
2. How to grow fast after germination
Adequate light: Generally, the orchid is in the budding period when winter and spring alternate. After it sprouts, it still needs to be provided with sufficient light and ensure the circulation of air.It can be placed near a sunny glass window in the room to provide more light for it.In addition, in addition to receiving light during the day, it is best to use fluorescent lamps for three to five hours at night to promote photosynthesis and make orchid buds grow faster and better.
Appropriate watering: After the orchid sprouts, the water requirement is stricter, and it can't be dry or wet.If the mother plant does not have sufficient water supply, it will not promote the growth of new shoots.You can put it in a high place, and then control the amount of water, not too wet or too dry, just keep the soil moist.
Appropriate temperature: After the orchid sprouts, it usually goes through winter, so it is necessary to take measures to prevent cold and freeze to ensure the appropriate temperature.Once the temperature falls below three degrees, it should be moved to a room with a temperature between five and fifteen degrees.
Timely fertilization: After the orchid sprouts, you can apply some more phosphorus and potassium fertilizer.After germination, orchids generally accumulate nutrients and do not continue to grow, at this time, phosphorus and potassium fertilizer can make them accumulate more nutrients and promote the growth of orchids.Organic liquid fertilizer special for orchids can also be used, which contains rich trace elements, can meet the growth needs of orchids and accumulate strength for the growth of orchids.
Remove buds in time: After the orchid sprouts, the orchid needs to accumulate a large amount of nutrients to supply the growth of flower buds.So too many flower buds will consume too many nutrients, making the growth of orchid buds uneven.Therefore, it is necessary to remove some orchid buds in poor growth condition in time, as well as flower buds beside old seedlings, etc., leaving only two or three flower buds in a pot.This will make the distribution of nutrients more balanced, and the buds will grow better.
