How to plant the latest Persian chrysanthemum seeds?
Persian chrysanthemum is an annual or perennial herb of the genus Asteraceae, native to Mexico. After Columbus discovered the New World, the crew collected seeds and brought it back to Europe for planting. Because of its lovable appearance and easy cultivation, it quickly stretched out from the garden to the countryside, mountains and forests to take root on the European continent. Let's take a look at how to plant Persian chrysanthemum seeds.
Sowing time
If Persian chrysanthemum needs to blossom in summer, it should be sown from February to March in early spring, preferably under the condition that temperature and humidity can be controlled. If you plan to sow seeds in the open air, you should sow in the middle of April when the temperature is suitable, and the seedlings can emerge in about a week when the temperature is suitable.
Sowing medium
The sowing medium of Persian chrysanthemum should be loose and rich in organic matter, and a certain amount of mature organic fertilizer should be applied before sowing. When sowing, mix the seeds with a certain amount of sand and spread them evenly on the seedling bed, then cover the soil for about one centimeter. After sowing, the soil moisture should be maintained and the temperature should be controlled at about 18 ℃.
Seedling stage management
When Persian chrysanthemum seedlings grow 4 to 5 true leaves, they can be transplanted into a nutrition bowl and heart removed. There is no need to apply topdressing during the seedling growth period, so as not to cause excessive growth of branches and leaves and affect flowering.
Growth period management
The plant type of Persian chrysanthemum is relatively tall, the stem is thin and weak, the flowers are large and beautiful, and they will lodge in the wind or other bad weather, affecting the ornamental value. Therefore, the whole growth process of Persian chrysanthemum needs to pick the heart many times and reduce watering, which can not only promote branching, but also dwarf the plant and avoid lodging in the growth process.
Pest control
1. Red spiders: Persian chrysanthemums are prone to red spiders when they are hot and dry. Whether you like it or not, Persian chrysanthemums have a high probability of giving birth to red spiders. Even if only two plants are planted, there may be red spiders, which should be detected and prevented as early as possible. 1000 to 1500 times of triclofenac EC was sprayed at the initial stage.
2. Powdery mildew: the density should not be too high when planting, and good ventilation and light transmittance should be maintained. Diseased leaves and plants should be cut off and destroyed in time after the disease, so as to strictly prevent re-infection. At the initial stage of the disease, 15% Fenru Ning wettable powder was sprayed 1500 times, or 10% Le WP 1200 to 1500 times. The two drugs were used alternately for 2 to 3 times.
