Chrysanthemum culture method how to raise Daquan chrysanthemum

Culture soil configuration:

The chrysanthemum substrate should be well drained, loose and fertile slightly acidic sandy loam. Generally choose the river sand with good permeability and permeability, and add garden soil and humus soil to prepare. The ratio is humus soil: garden soil: River sand = 4:4:2, if conditions permit, it is best to spray the cultured soil with disinfectants such as formalin or carbendazim according to the concentration of the instructions.

Water management:

The water management during the growing period of chrysanthemum must be carried out in accordance with the principle of "timely watering during drought and timely drainage during waterlogging". And make sure you have enough water before and after the pregnancy. Watering can also be combined with fertilization, but also pay attention to "see wet see dry", that is, neither half-dry and half-wet, nor too dry and too wet. There is to spray foliar water to the leaves once every morning and evening.

Controlled fertilization:

Chrysanthemum growth should be fully organic fertilizer (usually as a base fertilizer). In the vegetative growth period, topdressing is mainly nitrogen fertilizer, which can be combined with phosphorus, potassium and trace element fertilizer. this can make the chrysanthemum branches stout and straight and make the leaves fat. In the middle and later stage of chrysanthemum growth, topdressing should be based on phosphorus and potash fertilizer, and special fertilizer for flowers can also be applied. The way of fertilization can be the combination of soil topdressing and extra-root topdressing, and watering should be done in time after fertilization. Note that if the chrysanthemum leaves are small and thin and the leaves are yellow, 0.1% urea solution can be sprayed many times.

Placement and lighting:

The daily management of potted chrysanthemum not only does a good job in soil, fertilizer and water management, but also carries out timely management measures such as turning pot and pulling pot according to the growth and environmental conditions of potted chrysanthemum, so as to avoid affecting the growth and development of potted chrysanthemum due to light and other reasons.

It should be noted that the chrysanthemum is a short-day plant. The experiment shows that the chrysanthemum grows nutritionally under the long sunshine of 14.5 hours a day, and the darkness of more than 12 hours a day and the night temperature of 10 ℃ are suitable for flower bud development.
