Planting methods of Dutch Chrysanthemum

1. Sowing and reproduction

Sowing time is very fastidious, too early will lose the role of fleshy root, too late will affect the quality of fleshy root, so the best sowing time is from July 25 to August 15, but also in a warm sunny place, the room temperature can not be lower than 15 degrees, and then wait for it to take root and sprout.

2. Tillering propagation

Tillering plants are usually in the spring, dig out the overwintering underground roots, cut them into segments with a knife, and then plant them separately.

3. Cuttage propagation

Cut off the young tiller seedlings with a knife for cutting, and then use plain sand or perlite or vermiculite as the substrate, the temperature is kept above 20 ℃, to maintain air humidity, it can take root in about half a month, and then it can be planted in the basin.

4. Grafting cultivation

Wild Artemisia annua L. is generally used as rootstock for cultivation.

● site selection: Dutch chrysanthemum is a dry crop, it is necessary to choose plots with convenient transportation and close to water sources. Requires loose texture, fine broken soil, good air permeability, pH6.5~7 sandy soil or sandy loam.

● selects excellent varieties: according to the cultivation in this area for many years, the seeds imported from the Netherlands are generally selected, and the varieties are Fogus, Tabor, Vintor and so on, which are easy to cultivate and manage.

● should be prepared before sowing: planning and establishing internal and external ditch system as soon as possible. A horizontal ditch with a width of 35cm and a depth of 35cm was opened at the border length of 30m, and a vertical trench with a width of 30~40cm and a depth of 40cm was established every 10 rows, the width of the ditch was 40cm and the depth of the ditch was 50cm, and the depth of the ditch outside the field was 80~100cm to ensure smooth drainage. Ploughing the land as early as possible, applying basic fertilizer, applying potassium sulfate compound fertilizer 10kg / mu, making the border in the north-south direction, 90cm wide, sowing 3 rows, ditch width 30cm, deep 30cm more than to enhance soil permeability.

● sowing in time: according to the planting experience in recent years, the best sowing time is from July 25th to August 15th. Sowing too early will bolting ahead of time, vegetative growth into reproductive growth, losing the role of fleshy root; sowing too late, the rhizome overwintering damage, affecting the quality of fleshy root.

● precision sowing: on the border, strip sowing is carried out according to the row spacing 30cm, generally using 50 ~ 60g (25000 ~ 30000 seeds) per mu.

● sowing method: large area sowing machine is selected to sow seeds, sowing depth 1cm, and check the cover thickness after sowing. In case of rainy days, manual sowing can be added.

● timely mulch: watering and then covering grass after sowing, check seedling emergence and humidity after cover, remove mulch in time to prevent tall seedlings. In this way, the effects of high temperature exposure and rainstorm erosion on Dutch chrysanthemum can be prevented, and the evenness of seedlings can be ensured.

● just-in-time interseedling: the first interseedling was carried out at 5-6 leaf stage, the plant spacing was 6~7cm, and the seedlings were gently cut off with a knife, and the second interseedling was carried out at 9-10 leaf stage, plant spacing 13~15cm, the seedlings could be gently removed from the roots. At the same time, it is combined with clearing ditches, loosening soil and weeding.

● topdressing was timely and reasonable: the leaf color faded obviously in the middle stage of chicory growth. For the fields with poor growth, it is necessary to apply a small amount of potassium sulfate compound fertilizer, 5kg per mu, or amino acid high-efficiency liquid fertilizer for extra-root topdressing, and do not overuse chemical fertilizer.

● pest control: powdery mildew and brown spot are common. 65% tophan wettable powder can be sprayed. When aphids do harm. Spray with 1000 times of dichlorvos EC.
