Cutting is the most used method for breeding chrysanthemums. It is easy to operate, has a high survival rate, is not limited by seasons, and can maintain the original characteristics of the variety. Here I introduce a simple and easy way to insert buds.
The cutting period varies depending on the purpose of cultivation, the cultivation environment, and the type. According to the time, the early maturing species should be flowered 100 days after cutting, the medium-bred species should be 120 to 130 days, and the late-maturing seeds should be more than 140 days.
The domestic one-piece chrysanthemum or chrysanthemum is usually cut in the middle and the middle of June; in Japan, the single-day three-piece chrysanthemum cuttings are from late April to early May, and flower exhibitions are held in November.
To cultivate a large, colorful, plant-shaped chrysanthemum, it is necessary to start with a good selection of chrysanthemums. Cut the cuttings before cutting. Select a healthy, disease-free, new shoot or foot bud that was poisoned, and cut the top 10 cm to 15 cm long shoots at around 7 am, immediately immersed for 3 hours, then cut into lengths of six or seven centimeters. Bud with 2 large 1 caution leaves.
Use a sterilized, non-fertilizer 5 mm or so of ceramsite or crude river sand as the cutting substrate and cut into the seedling tray. The bud spacing is 6 cm 4 cm.
Before inserting, use bamboo chopsticks to punch holes 3 cm deep. Do not insert the chrysanthemum directly to avoid causing splitting to affect rooting. When cutting, use the special chrysanthemum root powder to carry out the root treatment. After inserting, gently press the substrate near the inserted bud, and immediately spray the water, cover it with bamboo curtain or cold cloth to avoid the wind and the sun. The degree of shading is preferably the thickness of a double-layered newspaper, and the light is too dark to be rooted.
In order to ensure that the roots of the cuttings are good, proper water control after cutting is the key, and the water is not good. It is not necessary to give water to the surface of the substrate within a week, even if it is a little wilting during the day, as long as it can stand up at night. When water is scarce, it is best to spray water properly in the morning and evening. Rooting can be carried out in about 10 days at 25 °C. After rooting, the bamboo curtain or cold cloth is gradually removed, so that it gradually adapts to daylight. At this time, spraying 1% leaf fertilizer containing nitrogen, phosphorus and potassium can make the plant robust.
15 to 20 days after germination is the best time to transplant.

Intermediate – Intermediate: A material produced during a drug substance processing step that must undergo further molecular modification or refinement to become a drug substance. Intermediates may or may not be isolated. Intermediates are the key products of the previous process of making APIs, which are different in structure from APIs.
for example:
Amoxicillin capsules are called preparations, amoxicillin is called API, and 6-APA is called intermediate.
Ceftriaxone sodium powder is called preparation, sterile ceftriaxone sodium is called API, and 7-ACA is called intermediate.
Our company specializes in providing key intermediates for various APIs
Intermediate is a very important type of fine chemical products. Its essence is a type of "semi-finished product", which is an intermediate product in the production of certain products. For example, if a product is to be produced, it can be produced from intermediates, saving costs and reducing It is widely used in the synthesis of medicines, pesticides, coatings, dyes and spices. In the field of medicine, intermediates are an important link in the industrial chain of the pharmaceutical industry. They are used for some chemical raw materials or chemical products in the process of drug synthesis. In a word, they are used to produce APIs.
