Methods of sowing and raising seedlings of potted daisies

Daisies are gradually loved by flower growers, and potted indoors. In order to grow daisies with beautiful colors, the way to sow daisies is extremely important, so how to sow daisies and raise seedlings?

Sowing potted daisies:

Daisy seeds are very small, with 4900-6600 seeds per gram, and family sowing is more than in September. There is a big difference in temperature between the north and the south, so families in the south mainly sow seeds in August.

Pot sowing should choose loose, breathable flowerpots. The flowerpot is disinfected and covered with vermiculite to cover a thin layer, so that the seeds should not be seen. Daisies can be transplanted once when they have 2-3 true leaves. The suitable pH value of sowing medium is 5.86.5, and the EC value is 0.50.750.After sowing, the temperature is 18-20 ℃, the humidity is 80-90%, and it can germinate in 5-8 days.

Keep indoor temperature of 18-22 ℃ and humidity of 80-90% after sowing. The radicle grows in a week or so. Still want to keep the medium moist after germination, need to be placed on the balcony to give light, but the germination time can not be too strong, to appropriate shade. From July to August, it is still necessary to cool down by shading around noon.

Cultivate strong seedlings:

1. Seedbed preparation: the seedbed soil should be fine and smooth, apply base fertilizer, spread evenly, plough and flatten the border surface per square meter, pour sufficient bottom water before sowing, and sprinkle a thin layer of sifted fine soil on the border surface after underwater infiltration, and then sow seeds.

2. Seed treatment: select good varieties and mix the seeds with 800-fold solution of new high-fat membrane (which can ward off underground diseases and insects, isolate virus infection, do not affect germination and swelling function, strengthen respiratory intensity, and improve seed germination rate).

3. Seedling stage management: seedlings come out completely, remove curtains, grow two or three leaves for the first time, bare roots without persistent soil, border soil needs to be moist, timely watering, loosening soil to preserve soil moisture squatting seedlings. When the seedlings produce 3-4 true leaves, transplanting with soil blocks once or twice can promote a large number of lateral roots and prevent overgrowth. Spraying new high-fat film after transplanting can effectively prevent aboveground water from evaporating and seedling water from transpiration, isolate diseases and insect pests, shorten the slow seedling period and improve the survival rate.

Growth management:

1. Weeding, watering and fertilization: after planting slow seedlings, weeding should be carried out to enhance soil permeability. After planting, watering should be done every 7-10 days. Do not need to fertilize too frequently, apply dilute dung water every 3 weeks, ploughing once a month, and stop fertilizing after flowering. Spray new high-fat film to preserve fertilizer and soil moisture.

2. How can flowering be colorful and fragrant? spraying Zhuangtiling at the bud stage can make the buds strong, the petals enlarged, the flowers colorful, the fragrance strong and the florescence prolonged.

3. Pest control: diseases mainly include leaf blight, chrysanthemum longicorn beetles, cotton aphids, Qichao, ground tiger, green leafhopper and other diseases. Diseases and insect pests should be mainly prevented, and targeted drugs should be sprayed with new high-fat film to greatly improve the effective components of pesticides. Not afraid of sun exposure and evaporation, can adjust the absorption of water-saving, drought and rain prevention.
