Spring sowing should pay attention to the need for a deep plowing of the soil before sowing, and then apply a layer of well-rotted farmyard manure as a bottom fertilizer.
After sowing, you should water thoroughly, then cover with a thin layer of soil, then evenly spread the seeds in the soil, and then water to keep the soil moist.
Bitter chrysanthemum seeds need to be shallowly hoed 2-3 times with a small hoe to ensure soil permeability.
When planting chrysanthemums, you need to pay attention to timely fertilizer, every 10 days or so after the nitrogen, phosphorus, potassium fertilizer; if the seeds are sown in the spring, you can directly sprinkle the appropriate amount of compound fertilizer can be.
If the seeds are sown in the summer, they need to be shaded and protected from the sun; when they are sown in the fall, the shade can be removed appropriately.
If the soil is relatively poor, you can also carry out a second fertilization (adding organic fertilizer to the soil) and tilling and harrowing; you can continue to plant chrysanthemum in the spring of the next year, but you need to supplement the fertilizer in a timely manner.
Additionally, after sowing chrysanthemum in the summer, you should also pay attention to the seeds to do a good job of sunscreen and shade, which can effectively prevent the emergence of pests and diseases.
1, seed selection
Select no pests and diseases, strong growth, high yield and stable yield varieties, so as to reduce the number of times and the amount of drugs, can improve the yield.
The cultivation of chrysanthemum can be harvested 2-3 months after sowing.
The seeding time of chrysanthemum can be sown from early August to late October every year, but it is best to sow in August to September.
Propagation of chrysanthemum seeds is usually done by sowing or strip sowing, with a spacing of 10 to 15 centimeters between the rows of strip sowing, and the amount of seeds used per mu is 0.5 to 1 kilogram.
Artificial inter-seeding method is used to inter-seed once, and keep the spacing between plants at about 15 cm.
2, land preparation and fertilization
The next step is to level the soil with a harrow, and then make the border.
Generally in accordance with the 2-3m ditch, ditch width of 30cm or so, about 20cm deep, and then rake with a rake can be raked.
Additionally, you should pay attention to timely watering after sowing chrysanthemum, and do not water too often.
When the soil is dry, you need to irrigate in time.
3, watering management
In the chrysanthemum seedling period, to keep the soil moist, but not waterlogged.
If it is in the hot summer, be sure to pay attention to watering the seedlings about three times a day.
But be sure to avoid stagnant water, or it will cause root rot and death.
Then when the seedlings grow to 15 centimeters, they can be inter-seeded and fixed, and then watered; when it comes to the time of flowering, the watering should be increased appropriately.
4, pest control
Generally, in its growing period only need to regularly spraying agents can be.
The common diseases are standing blight, sudden collapse disease and leaf blight.
For these diseases, we need to do a good job of daily care, you can use 50% carbendazim wettable powder 1000 times liquid to spray at the onset.
And for insect pests we need to do a good job of prevention, can be found when the use of abamectin, mevinphos and other agents for its spraying control.
