Production process of phoenix

Please introduce the process of producing chrysanthemum that has been researched and applied by scientists at the Institute of Agricultural Genetics.

Planting season : In the areas of Da Lat, Tam Dao and Sa Pa, it is possible to grow all year round. Also in the Northeast region should be planted in the winter (September) and winter-spring (from November to December).

Soil preparation: Need to plow carefully before planting, pay careful attention to soil hygiene by applying lime to the soil (20-25kg / rod), sprinkle it on the field. In addition, it is also possible to use CuCl ₂ with concentration of 0.2-0.3%. Then proceed to the bed, make the cut. The bed surface is 0.9-1m wide and 0.45m wide. The distance between the rows 15-20cm, the tree is 10-15cm away, the density of planting: 8000-9,000 sprouts / rod. Finally flatten the beds and small surface soil dams.

Fertilizer (used for 1 sao): 400kg of manure, 25-30kg of nitrogen, 20kg of phosphate, 10kg of potassium and other micro-fertilizers containing Cu, Co, Mg, Mn . Note, do not use manure Fresh cages for fertilizing will create pathogens for flowers, fungal root rot. Applying the entire manure, 3/4 phosphate, applying 1/4 of the remaining phosphorus, then applying the first phase: 3kg of nitrogen + 1kg of potassium (mixing with water to irrigate). Top dressing

2: 5kg of protein + 2kg of potassium, so on 10-20 days, apply one time. It is also possible to use some foliar fertilizers to increase flower yield.

Care and pest control : Do not allow plants to dry, water every 1 to 3-5 days. 7-10 days after planting, the plants begin to take root and water with diluted manure, combining weeding and breaking scum. After 30-40 days, start pruning the axillary buds of the flower (stay at the main stem 2-3), remove all branches on the stem and stem, continue to cultivate the tree, make the truss, keep the tree closed wind. Phosphorus often suffers from diseases of gray rot, yellow wilt, brown spot, bacterial wilt . so it is necessary to monitor and take timely preventive measures.

Harvesting : Conduct cut flowers when there are 1-2 blooming flowers, when cut flowers need to leave stem 2-3 leaves to feed the plants, cut the bundles together, wrap the outside with newspaper, put in the shadow dark and out of the wind, then put the original 1/3 into the water tank to keep the flowers fresh.
