Daisy is one of the traditional flowers, good variety, cultivation has a long history, with a wide range of application. Potted Chrysanthemum in China, mostly in potted chrysanthemum chrysanthemum bull turned around, much the most representative of the chrysanthemum cultivation, cultivation of high technology, requiring long strain (strain Saegusa three flower by flower head daisy three, five strain branch flower head daisy Five who is five, seven strain of seven branches flower chrysanthemum flower heads were seven, and so on), the main branch obviously, evenly distributed branch, shorter plant type, robust plant growth, plant type perfect, erect stems, evenly distributed between sections, thickness and height appropriate, positive leaf, leaves, fresh leaves stretch, no pests, no injury, can fully demonstrate the breed characteristics.

1. cuttage

(1) Nursery preparation

First to prepare the nursery container, large-scale production to prepare the seedbed, then good preparation cutting matrix, the matrix preferably SOILLESS to Longkang formulated with perlite 1 ~ 3:1 better. The prepared matrix is ​​placed in nursery containers or seedbeds filled with a thickness of 10 ~ 15cm, after leveling spare. Cutting nutrient supply itself is growing cuttings, so the matrix can contain nutrients, but also do not have to be administered basal.

(2) Cutting Time

Best cutting period before the end of May to June rainy season comes hot yet. Cuttings should be determined according to the length of time of breeding, topping the first time the number and fixed. General SOILLESS breeding period of two weeks, there is soil matrix breeding period of 20 days. Huanmiao 10 days after topping the basin, will be head of the 25 July ~ early August, no later than the beginning of autumn. To set the basin after the first press cultivated chrysanthemum long number of requests, topping 1 every 20 to 25 days, topping the number of projections based on the best cutting period.

(3) Cutting

Choose good, robust, no pests cuttings, nursery cuttings generally use more chrysanthemum strains after repeated topping germination, cuttings length after finishing in 5 ~ 6cm appropriate. 1 ~ 2cm when finishing can be broken at the lower nodes in the cuttings, removing the base of the blade. Cuttings should not be too long, in order to control the height of the future. Cuttings picking avoid exposure, shall be placed in the shade and water or slightly in 清水中浸泡 to keep moist, pest control agents may be added in the water. Cutting the spacing of 3cm, large leaf and some varieties may be relaxed. 1/3 insert the cuttings when cutting the matrix, after inserting the cuttings gently press with your fingers around the base matrix, the matrix makes cuttings closely, plugged portion after watering can with a fine or a multifunction gun with a fine mist spray enough water, the future to continue After the cutting, to be cutting, such as lack of water and repeat spray 1 times. For some rare species and high temperature conditions is not easy rooting cuttings varieties available abt promote rooting.

(4) Nursery Management

Mainly to control temperature and humidity, the cuttings early to maintain high humidity in the air relative humidity above 80%, or even close to saturation better. During the first three days after cutting to maintain high humidity does not make cuttings wilt is a crucial step. During this period we must continue intermittent spray, spray requires a short time interval, less water, more often, during the day, morning and evening spray interval slightly longer, noon short interval. Rainy days water quantity and water frequency should be reduced accordingly. 4 to 5 days after cutting the amount of water can be gradually reduced. Chupu three days before a postemergence to lower the temperature, water control, exercise seedlings adapt to the external environment.

(5) other management

Cutting one week after the cuttings sectional basically formed callus, root primordia began cuttings store itself has been largely consumed nutrients leaves begin to yellow, to replenish nutrients, can be sprayed with 0.2% potassium hydrogen phosphate, tris and 0.2% urea 1 to 2 times. Kikunae former nursery pest control spraying of pesticides.

2. pots and Huanpen

Rooting a timely postemergence to the basin, the basin of the relevant age seedlings with fibrous root 2cm long time as well. The basin is more timely manner with nutrient-free soil-less medium nursery. When the basin to avoid root damage, the available smaller pots, avoid big tub species seedlings, nutrition area is too large, excess nutrients, plant growth, excessive pre-and large area with a big tub, inconvenience management. Yi Qian planted when the basin, basin do not fill once installed, can be fitted to large Banpen later Kikunae grew up with and then gradually add the soil. To bowl a little vibration after the basin and gently repression basin, basin irrigated after pragmatic. New pots of chrysanthemum seedlings should be placed shade, after three to four days to move to sunny place Huanmiao normal maintenance and management. Chrysanthemum plants to be grown, roots covered with container, fibrous root emerges from the hole when the pots will be planted in small pots of chrysanthemum plants were transplanted into a larger pot and add the basin, in order to expand the nutrition area. During the whole growing long-ju can Huanpen 1-2 times, mainly based on the number of long daisy flower may be. When the basin is generally the first species in the basin 10 ~ 12cm diameter pots, and back to the basin 15 ~ 20cm diameter pots, and back to the basin 25cm diameter pots. Huanpen must add each basin and irrigated.

3. topping with fixed head

Chrysanthemum cultivation bulls several times topping, whose role is to promote germination collateral chrysanthemum plants, flowers form the optimal number, easy to control plant height, to prevent excessive growth, prevent the occurrence of willow head. Ju long topping: three Ju can topping 1 or 2 times, five Ju can topping 2 to 3 times, seven daisy, chrysanthemum topping nine times accordingly more. 1 topping those in the 10 days after the basin, the base can stay 3 to 5 leaves; repeatedly topping those at branch length to 15cm were, after topping the base, leaving only 2 to 3 leaves, easy to control plant height and branching number. Finally, once a topping before July 25 to be the beginning of autumn, also known as constant head.

4. fertilizer and water management

(1) Water management

Chrysanthemum hi humid, avoid water damage, waterlogging and easy death. Watering too easy to make chrysanthemum plants leggy, insufficient watering chrysanthemum plants would affect growth and development, the amount of water according to different species, different growth stage and weather conditions, the principle is timely and appropriate, Pentu see dry see wet , do not quit pouring, pouring to be drenched. When small and chrysanthemum plants after topping, less water consumption each, for the promotion of full axillary bud, to control watering. Chrysanthemum plants grown with higher temperatures, increased evaporation, water consumption is increasing, should be appropriate to increase the amount of water. In the rainy and typhoon season rain, the rain water basin, the water should be promptly discharged. In the vegetative growth, to control the height of chrysanthemum strains to morning watering is appropriate, the amount of water needed to be able to maintain normal growth. Flowering watering, usually in the flower bud differentiation stage to appropriate water control, to facilitate flower bud differentiation; the buds, bud color dew, petal rapid development when they have adequate water supply, in order to open the huge flowers. To control the soil moisture, can be foliar spray method, foliar spray can leaf wetness and prevent leaf aging, improve photosynthetic capacity.

(2) manure management

Hi fat are more Naifei chrysanthemum, chrysanthemum long basin is nutritive soil used in the preparation of various fertilizers have been added without further Fertilizers. During the birth of chrysanthemum strains constantly replenish nutrients quick result topdressing fertilizer, such as fermented bean dilution water, bone meal, compound fertilizer, etc., can also be sprayed weekly 0.1% to 0.2% urea and potassium dihydrogen phosphate solution, and Pentu continue to add to supplement nutrients.

5. dwarfing process

To control the height of chrysanthemum plants, spraying a timely manner after topping dwarfing agent, and can be sprayed B9 400 ~ 600 times, dwarfing agent to be sprayed unresponsive to 400 times more sensitive reaction can spray 600 times, too can be sprayed MET (150 ~ 300 × 104 dilution), general spraying 2 to 3 times, on pedicels specialty varieties to flower stalk elongation before spraying dwarfing agents.
