Snow lotus fruit, also known as Yagong or Argonne, means "divine fruit". Chrysanthemum potato is a perennial herb in the composite family, so it is also called chrysanthemum potato. The root tuber of chrysanthemum potato is rich in water and fruit oligosaccharides. It tastes sweet and crisp and can be eaten as fruit. So, how is Saussurea involucrata planted? What should we pay attention to in cultivating snow lotus fruit? Please read with me with questions!
Seed and reproduction method of Saussurea involucrata tuber (basic knowledge): the best reproduction time: Saussurea involucrata can be sown in spring and autumn; Leaf cutting is best carried out in autumn;
The best growing soil: snow lotus fruit can be mixed with peat, perlite and pumice in the ratio of 1.5:1:3; It can also be replaced by sapropel, perlite and cinder;
Growth humidity requirements: the humidity of snow lotus fruit is between 12.8% ~ 54.2%;
The best growth temperature: the growth temperature of snow lotus fruit is 5-25 degrees. When the temperature exceeds 25 degrees in summer, it begins to semi dormant, and when the temperature is lower than 5 degrees in winter, it basically dormant.
The best growth light: snow lotus fruit is maintained in semi shade in summer, properly shaded and made use of scattered light. Spring, autumn and winter can be taken all day.
Precautions for planting snow lotus fruit with snow lotus fruit leaves: apply fertilizer: the three elements of nitrogen, phosphorus and potassium in snow lotus fruit should be used reasonably according to the situation.
Generally speaking, nitrogen fertilizer should be mainly applied in spring to promote the growth of branches and leaves; In summer, phosphorus fertilizer was mainly applied to promote the expansion of stems, leaves and buds; In autumn, more potassium fertilizer is applied during flower bud pregnancy to promote flower brilliance and grain plumpness, combined with spraying Gaoxin lipid film to enhance fertilizer efficiency. The use of huazhuangdiling at the bud stage can make the flower buds strong, the petals hypertrophy, the flower color gorgeous, the flower fragrance rich and the flowering period prolonged.
Watering points: snow lotus fruit belongs to stone lotus. Generally, it will be watered through the basin and placed in a ventilated place to wait for new roots. In the growing season, the principle of drying and watering shall be followed. It's best not to water the leaves, which will affect the beauty. After the temperature is lower than 5 degrees in winter, although it is dormant, you should also give some water.
Basin soil replacement: snow lotus fruits generally do not need to change pots, because the growth period is less than one year; Except that the pots need to be moved during seedling colonization, the pots generally do not need to be changed if there is no rotten root or root system problem.
Breeding points: Saussurea involucrata generally adopts leaf cutting and sowing.
1. Leaf transplanting: select mature but not yellowing leaves for leaf transplanting, put them in a bright and ventilated place to dry the wound, and then put them flat on slightly wet sandy soil or coarse sand, and put them in a cool and ventilated place to wait for rooting. After rooting, small buds will appear on the leaves. When the buds grow to a little big, they can be transplanted. When moving the pots, try to bring some soil, which is conducive to the healthy growth of the seedlings in the new environment. The seedlings after moving the pots can be managed normally for a period of time.
2. Sowing: snow lotus fruit can be sown in spring and autumn.
The soil temperature of snow lotus seed germination must be controlled between 20 ℃ and 26 ℃, which is conducive to seedling emergence. The saturated water content of soil is required to be about 60%. The seeds are placed flat in the hole. The thickness of soil covering is the length of the seeds or 0.8cm ~ 1cm. Generally, the seedlings emerge in about 8 days.
The growth period of snow lotus fruit is about more than 200 days. (spring sowing) snow lotus fruit enters the flowering period in September. Each branch opens five yellow sunflowers. After flowering, it enters the mature period. After all branches fail, it can be harvested one after another.
Pest control:
Snow lotus fruit snow lotus flower blight mostly occurs during the seedling period, and the bacteria can infect and cause dead seedlings. Preventive measures mainly include the following:
1. Basin soil shall be fully sterilized;
2. Apply rotten fertilizer;
3. Basin soil is not easy to be too wet;
4. The diseased plants were removed immediately and sprayed with fungicide, combined with spraying with Gaoxin lipid film to enhance the control effect.
Planting experience of snow lotus fruit planted in the harvest area: pay attention to the following details when planting snow lotus fruit:
1. Prevent seed reverse planting: snow lotus seeds are conical. When planting, the seed tip is downward, which is easy to emerge, but the seedlings are not strong, and the seed tip is upward, which is difficult to emerge. They must be planted flat.
2. Prevention of rotten seeds: the weather in early spring is cool, the soil temperature is low, the humidity is high, and the seedlings do not appear in 10 days, indicating that the seeds have become black and rotten, so pay attention to the key problems of soil temperature and humidity in planting.
3. Prevent seedling from being unearthed with cap: Seedling unearthed with cap directly affects plant development, resulting in seed coat being taken out when cotyledons are unearthed. The reason is that the soil is too loose and the covering soil is too dry.
4. Prevent watering hard water: it is best to use snow water, rain water, river water and lake water before 10 a.m. or after 3 p.m. during seedling raising. If tap water is used for watering, it must be stored in a bucket for one day and night to volatilize chlorine in the water, and the water temperature is close to the soil temperature.
