Cultivation techniques of desk Chrysanthemum

Single desk chrysanthemum

The main results are as follows: 1. the desk chrysanthemum should choose the excellent varieties of large flowers with early flowering, stout stem, dense stem node, thick leaf, large root system and sensitive to B, etc. The varieties suitable for desk chrysanthemums are: "White Hydrangea", "Golden Lion head", "Frost on the Grass", "West Chamber waiting for the Moon", "Pink Lion head", "Xutao", "Huang Shigong", "Tiger Xiao", "Huaguang Cloud", "Queen", "Cloud of the Plateau" and so on.

Second, cutting seedlings are generally suitable for cutting from late July to early August. Choose the top tip of the strong, full, pest-free mother plant as cuttings, about 4 cm to 5 cm long, keep 2 leaves in the upper part of the cuttings, remove the lower leaves, flatten the incision with a blade, and insert it in the seedbed in time. Pour water once after insertion, and build a circular arch shed on it. The shed is about 2 meters high, covered with two Reed curtains to shade, and a plastic film is sandwiched between the curtains to protect against rain and moisturize. Start watering every morning and spraying at noon. After two weeks, remove a Reed curtain and appropriately reduce the number of watering and spraying. Generally, it takes about 15 days to take root, and about 25 days for pots.

3. 5 parts of garden soil, 2 parts of rotten leaf soil, 2 parts of garbage soil, 1 part of plant ash or 4 parts of garden soil, 2 parts of stable fertilizer soil, 2 parts of rotten leaf soil, 1 part of furnace ash plus a small amount of lime and bone powder should not be mixed. Bone powder should not be too much, because too much phosphorus leads to stem and leaf aging. The upper basin soil is only 60% to 70%, preventing the jointing growth of chrysanthemum plants. Add 10% in early September and 10% soil in late September, cover the culture soil about 2 cm thick twice, bury the two or three old leaves at the base, make the stem nodes at the fork grow large leaves, cover the basin surface, and form a pagoda shape with large crown width and small crown width.

Fourth, water and fertilizer management cuttings are put into pots everywhere at the end of summer, which lasts for about 25 days. This is the root maintenance stage of desk chrysanthemum. In this stage, only water is watered for about 20 days, and water is controlled for the next 5 days. The roots are irrigated with rotten thin human feces and urine for 1 to 2 times, and the concentration is 5%. Promote its root growth. After potting, the bud obviously formed for about 20 days, which was the stage of raising leaves. During this period, the temperature was high, the water was watered once from 9 am to 10:00 on a sunny day, and the water in the basin was evaporated after sunset, which could effectively control the height of chrysanthemum plants. Dusk and early morning are the two peak periods for the elongation and growth of chrysanthemum seedlings, so watering must be strictly prohibited. Individual chrysanthemum plants that lack water can be irrigated with a small amount of sprinkler irrigation, which is called "looking for water". Fertilization is mainly nitrogen fertilizer, two or three days to apply rotten dilute bean cake water once, the concentration is 5%, 0.1% urea can be added to the fertilizer solution to irrigate the root. Make the leaves fat and bright. After the bud formation to the dew color, about 25 days, is the flower cultivation stage. This period of time is when the autumn is crisp, the temperature is higher, the air is dry, the desk chrysanthemum basin is small, coupled with the chrysanthemum plant has taken shape at this time, so watering should be sufficient, generally watering once a day from 9 am to 10:00,. Spray clean water to the leaves from 5 pm to 6 pm, be careful not to irrigate directly, and store the water in the tank for two or three hours before watering. In sunny and windy days, we have to look for water in the evening. The lack of water during this period is easy to cause leaf wilting, and long-term wilting is harmful to the development of roots and buds. The main fertilizer used in bud stage is phosphate fertilizer. Every morning, add 0.1% potassium dihydrogen phosphate to the root of bean cake water dilute solution. Urea and 3000-fold solution of potassium dihydrogen phosphate were sprayed manually every 3 days.
