Last Updated: 2024/11/22, 1. Selection and cultivation of rootstocks grafting chrysanthemum generally uses Artemisia annua of Compositae as rootstock. The seedlings were sown and raised at the end of September. In the first ten days of November, the seedlings of Artemisia which began to elongate at the end of the stem and grew healthily were planted in a small basin and placed in a greenhouse to survive the winter. The temperature was generally controlled at 10-15 ℃. After the survival of transplantation, thin fertilizer can be applied to promote growth. Water is watered once a week and the humidity is maintained at 50 degrees 60%. In the early and middle February of the following year, lateral branches can sprout from each node of the plant. After breaking the frost, you can leave the room after waiting for the height of the plant to be about 40ml / 60cm. Before leaving the room

After breaking the frost, you can leave the room after waiting for the height of the plant to be about 40ml / 60cm. Before leaving the house, we should choose the planting site with high dryness to the south, dig a good hole, apply rotten basic fertilizer at the bottom of the hole, place culture soil at the top of the hole, and plant one plant in each hole.

2. Grafting technique

1. Selection of scion varieties: varieties with the same florescence, larger flower type and long florescence should be selected and arranged according to flower color. Generally require the same color to the top or with two or three similar primary colors of different colors from the bottom up from shallow to deep or from deep to shallow. Take red as an example, it can be arranged according to light red, pink, water red, bright red, purple and deep purple, which looks both coordinated and eye-catching.

two。 Grafting time and method: grafting in greenhouse, usually in January-March of the following year, such as open field, can be extended to April-May, but no later than "Grain in Beard". When grafting, it begins with a layer of branches 20ml 23cm above the ground and is grafted every 7 to 10 days. When the lateral branches grow to about 10 cm, the first round of grafting can be carried out. Each round should not be grafted too much. Generally, 6 branches are required. In order to reflect Baopei's arrangement, from bottom to top, there are 6 branches in the first round, 5 branches in the second round, and 4 branches per layer in the third round. Each layer should be 20 cm apart and the excess lateral branches should be removed as soon as possible. When grafting, truncated Artemisia annua should not be too old or too tender. If the pith is found to be white, it shows that it has aged and can be discarded. However, it is too tender to form a pith, and it is not suitable for grafting, so it is best to choose the young part of the stem with normal thickness and large leaves, and then cut off the top of the selected 5 cm long chrysanthemum branch scion, use the "splitting method" for grafting, and then bind the interface with soft bindings such as cotton yarn, or select willow, elm or hibiscus branches slightly larger than the rootstock stem. Cut every 10cm around into a small section, twist and remove the central xylem to make a 2 cm long "leather ring". When grafting, it is appropriate to put the apron into the rootstock, wait for the scion to be inserted, and then pull the apron to cover the cut direction and tighten it.

Third, the post-management of Taju:

The grafted chrysanthemums should be placed in a shaded place and sprayed with water after an interval of 4 hours. If you pick up in the afternoon, you can spray water the next morning, then twice a day, and stop a week later. Watering should be poured on the root of the rootstock, do not pour it on the cut, so as not to rot. (2) after 3 weeks, the binding material was released and moved to open-air culture.

A heart pick was conducted in the first ten days of May, and then it was picked every 25 days, and four leaves were retained for a total of four times until the Beginning of Autumn.

From July to September, liquid fertilizer was applied every four or five days until budding.

In early September, tower chrysanthemum can be put on the basin, which must be carried out on a sunny day. First dig up the complete root system, which can not be cut off at will. Should choose 80 centimeter caliber flowerpot, should not be too small. The cultivation techniques of chrysanthemum should be watered every few days after going into the basin, and then applied after the week.

After the chrysanthemum bud, it must stand on the pole to set up a fight. Use bamboo as a frame, make a pillar in the center close to the dried Artemisia, and then tie a disk on each layer, the size of the plate is determined according to the chrysanthemum branch, generally from bottom to top, from large to small, to the top circle, often not less than 10 centimeters, if the bamboo frame is painted green, then the ornamental effect is better.
