Commercial Chrysanthemums Cultivation Technique is also prominent for Agribusiness.
climate and soil-
Chrysanthemums like relatively cold weather and sunny places. winter is the best time to grow this flower in Bangladesh. organically rich suniskashit do fibre and belle soil is suitable for Chrysanthemums cultivation. the ph of the soil is 6.0-7.0.
Chrysanthemums saplings can be made from seeds, sakars and branch pens. saplings from seeds do not yield good flowers and it takes a long time to get flowers. on the other hand, it is not a problem if you cut pulses and pen branches or saplings from sakars. saplings are usually made by branch pens in this country. branch pening started in mid-july. a 1-year-old fresh strong dal is cut into 8-10 cm long branches and placed in a bed or bucket to grow roots. when the flowers were finished in february, the trees were cut down by keeping 15-20 cm on the ground. after a few days, some sakars come out from the base of the area. when these sakars are 5-7 cm long, they are separated from the mother tree and planted under a shady seed or tub. arrangements have to be made to save the saplings from rain and harsh sun in may-july.
the suitability of producing flowers can be increased by crushing the saplings on individual land or tubs before planting them at a specific place or tub for the last time. the right time to plant saplings inland or tubs is October- November. Chrysanthemums should be planted at 30 x 25 intervals.
Chrysanthemums tree absorbs a lot of food from the soil. that is why this tree responds very well to organic and chemically edible soils. to get a good yield, a balanced quantity of fertilizer should be applied to the field. 10 tonnes of rotdung/compost, 400 kg urea, 275 kg tsp, 300 kg muret of potash, 165 kg gypsum, 12 kg boric acid and zinc oxide fertilizer should be applied per hectare. 10-15 days before planting sakar, the fertilizers other than rotdung/compost and urea should be mixed well with the soil 7-10 days in advance. after 25-30 days of planting the sakar, half of the urea fertilizer should be applied and the remaining half of the fertilizer should be applied a little away around the base of the tree 45-50 days after planting the sakar. after applying the surface, the fertilizer should be mixed with the soil and irrigated.
Chrysanthemums’s bed and tub should be kept weed-free. after a month of planting saplings, the tip of the tree has to be cut. this makes the tree bushes in not long. in the sapling tree, flowers have to be removed immediately. to get large flowers, you should do disbudding i.e. keep the middle bud and cut the two buds next to it. and if you want to get medium-sized flowers, you should remove the middle twenty.
Chrysanthemums’s saplings should be planted in the afternoon and the ground should be squeezed. light irrigation should be given after planting saplings. Chrysanthemums’s trees can never tolerate much water. therefore, water should be given in such a way that water does not accumulate at the base for long. regular irrigation of water is important every day before and after planting saplings.
Chrysanthemums flowers are usually bigger than branches. so a hard stick has to be buried from the base of the tree to the bud. it won’t make flowers go down. it is better to bury the stick at once while planting saplings. therefore, according to the height of the Chrysanthemums tree, the bamboo stick should be buried a little away from the base of the fodder. once the root or tree grows at the beginning, the roots of the son can sometimes be damaged, even due to wounds on the roots, the disease can enter the plant and cause diseases.
Suppressing absorber insects:
the absorber insect is very small in shape. this ash-coloured insect is not visible to the naked eye. insects absorb leaves and flower juice. this causes scars on the affected leaves and flowers. leaves and flowers dry up and trees also dry up when the attack is high. to control this insect, 2 ml of malathion should be sprayed in 1 litre of water for 7-10 days.
Jab insect suppression:
jab insects are the main harmful insects of flowers. the jab insect is green, purple or black in colour. both minor and adult sap lingua or flower juice of the tree and cause fatal damage to the growth and yield of the tree. this insect can be suppressed by applying novakron (0.1%) or roger (1%) .
powdery mildiu disease prevention:
when cured, the leaves of the tree are grey and white powder can be seen on the leaves. the disease can be controlled by mixing tilt 250ec 0.5 ml or 2 grams of theovit per litre of water and spraying it every 7-10 days.
Chrysanthemums do not boil when she raises flowers in a bud. in case the outer petals are completely opened and the middle petals are beginning to bloom, flowers should be cut with long nipples with sharp knives early in the morning or afternoon.
the yield is less or less in caste. however, the tree gets an average of 30-40 flowers every year.
