The sowing method of when to sow chrysanthemum seeds

Chrysanthemum has been planted in our country for a long time. Since ancient times, there are some records about it in some books. It is a kind of flower variety that integrates ornamental and practical features. At present, there are many people who grow chrysanthemum, but most people want to have a comprehensive understanding of its planting technology before planting it.

When will the chrysanthemum seed be sown

Chrysanthemum seeds can be sown in autumn and spring. Seeds need light to germinate, cover a thin layer of soil, or not cover the soil, and put the pot where there is light. If the temperature is low, you can cover the basin mouth with a layer of fresh-keeping film to keep warm and moisturize at the same time. It blossoms in summer, about 7500 grains / g, the optimum temperature for germination is 18: 22 ℃, light is needed, and the germination time is 12-16 days.

Sowing methods of Chrysanthemum Seeds

1. Soil selection: when sowing chrysanthemum, loose soil rich in organic matter should be selected, and a certain amount of mature organic fertilizer should be applied as base fertilizer before sowing.

2. Sowing method: when sowing chrysanthemums, mix the seeds and a certain amount of sand evenly, and spread them evenly on the seedling bed, then cover the soil for about one centimeter.

3. Post-sowing management: chrysanthemum should maintain soil moisture after sowing, the temperature should be controlled at about 18 ℃ to germinate, and the temperature, air humidity and sunshine should be sufficient.

4. timely transplanting: when the chrysanthemum seedlings grow 4 to 5 true leaves, the chrysanthemum seedlings can be transplanted into the nutrition bowl and removed from the heart, and 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.

How can chrysanthemums be fat and watery?

1. Fertilization:

1. Chrysanthemums are very fat, but if they are not fertilized properly, they will grow in vain. When applying base fertilizer to chrysanthemum, potassium and phosphate fertilizer can be used as the main fertilizer. Fertilization time is not too early, you can choose the Beginning of Autumn to diaphragm to plant flowering, this period of time must ensure that chrysanthemum adequate fertilizer and water. When applying fertilizer, the concentration of fertilizer can be increased gradually.

2. In the seedling stage of chrysanthemum, the amount of fertilizer needed is relatively small, which can be fertilized once or two days a week, and fresh water fertilizer should be applied; during its growing period, the seedlings grow slowly, and the fertilizer needed will also increase. At this time, you can increase the frequency of fertilization, about 5 to 7 days of fertilization; and from July to August, when the temperature is high, it is necessary to appropriately reduce fertilization so that the growing chrysanthemum can safely spend the summer. From September to October, the temperature gradually dropped, which is also the most vigorous period of plant growth, which can increase its concentration while increasing the number of fertilizers.

Second, watering:

1. When the temperature is very high and very dry, there is more water loss, and we have to water it once or twice a day.

2. When the temperature is relatively low, or on cloudy or rainy days, we water much less, so we can directly choose not to water. If there is a heavy rain, we should pour the water out of the basin soil and not let it rot and die.

3. If it is a new basin, there must be enough water for the first time.

4. We can't water it too much during its seedling period, and if it grows up and the temperature gets higher and higher, we have to give it more water. Generally speaking, the reason for controlling it in the early stage is to control its height, and then the main reason is to make the buds grow well.

The method of shaping and pruning Chrysanthemum

Timely coring can promote the growth of lateral branches and depress the plant height. Due to the different artistic shapes of chrysanthemums, the time and times of heart picking of potted plants are also different. In the northern region, ordinary family chrysanthemum potted plants generally retain 7 flowers. After the chrysanthemum seedlings are planted, they retain 5 leaves to pick the heart, and when the lateral branches grow out 5 leaves, each side branch will retain 2 Mel and 3 leaves for the second time.

There is a lot of time for chrysanthemum planting, spring and autumn are OK, you can choose the planting time according to your own situation. Before planting, it is necessary to do a good job in the proportion of soil, and then sow seeds at the right time. Management needs to be strengthened after planting in order to ensure the survival rate of chrysanthemums.
