Seed China believes that raising seed germination rate of flowers is a highly technical task. In order to increase the emergence rate, it is necessary to understand the reasons that affect the emergence rate so that they can be reasonably disposed. Seed quality problems At present, there are many flower seeds on the market. At the time of purchase, flower growers should pay attention to the production date and shelf life indicated on the packaging bag, whether domestic seeds or imported seeds. Unmarked seeds should not be purchased because most of the expired seeds have lost their vitality and they will not germinate. In addition, when buying seeds, flower farmers should have a basic understanding of them, such as whether to grasp the seeds to be bought is a two-year-old flower, or perennial flowers, spring flowers or autumn flowers. In general, seeds sowed in spring usually bloom in summer and autumn; seeds sown in autumn generally bloom in spring and summer (except woody flowers). If the sowing date is reversed, and there is no definite anti-season cultivation condition, it is difficult to achieve the goal of flowering. It is even more cautious to buy flowers that have never been reared. Seed treatment is not in place Different flower seeds should adopt different seed treatment methods. Seeds that germinate easily can be soaked with seeds. For example, a bunch of red seeds can be soaked in warm water at room temperature of 40°C for a day and night and rinsed. Hard seeds, such as asparagus, peony, hariri, beryl red, and reed, etc., are best soaked in hot water at 40°C for about 48 hours and sowed in pots and soils. After 20 days to 30 days, they can germinate. Grow. For the dormant period, easy to germinate the Pearl Plum, Bauhinia, soaking with warm water 40 °C ~ 60 °C for 24 hours to 48 hours can be directly sowing. Some flower seeds need to be treated with low temperature for a certain period of time in order to promote post-harvest, break the dormancy of the embryo and germinate, such as cloves, waxy plums and some autumn-sown herb flowers. Some flowers have the characteristics of double dormancy of radicles and hypocotyls, that is, their radicles need to pass the high temperature stage of 25°C to 32°C for 1 to 2 months or longer to break the dormancy, such as the seeds of tassels, pupa, and peony. . Ignore seed germination and temperature In addition to certain water conditions, the germination of dry seeds must also have a certain temperature. For example, cruciferous incense bulbs must germinate at a suitable temperature of 5 °C ~ 20 °C, Gerbera germination temperature must be 20 °C ~ 25 °C, Primrose germination temperature must be in the range of 15 °C ~ 18 °C, the temperature is too High or too low will affect the emergence rate of flowers, and even cause the emergence of seed rotten phenomenon, greatly reducing the germination rate and seedling rate. Sowing time is unreasonable Large seeds, solid or oily seeds, such as rose, rose, pomegranate, kumquat, broad magnolia and other flower seeds, suitable for sowing in the autumn. The seeds with smaller particles and loose skin, such as chrysanthemum, asparagus, impatiens, araceae red, and gardenia, are suitable for late spring sowing. Seeds that need high temperature to germinate should be sowed in time after maturity. Such as cyclamen, cineraria, and primrose should be sown in early summer. Problems with sowing quality There are two forms of open sowing and pot sowing in the sowing of flowers. No matter which method requires loose soil and ventilation, fine particles, and good drainage, it is better to use humus-rich nutritious material with moderate acid-base fertilizer, which is beneficial to seed emergence. Specific sowing methods include sowing, drilling and sowing. The water must be poured before sowing, covered with plastic film after sowing, to prevent the soil from drying and affecting seed germination and emergence. The sowing depth is generally 2.5 times the diameter of the flower seeds. Small cockscomb, August chrysanthemum, sea bream, cineraria seeds, etc., spread finely after applying fine sand and seeds. After germination, the seeds should be sprayed with moisturizing water, but the water spray should not be excessive to prevent the fibrous roots of erosion seeds and seedlings. Ignoring the effects of light After sowing of flower seeds, proper lighting can increase the temperature of the soil and induce seed germination. It is especially important for seeds to break through the seed coat and root buds. This not only affects the seedling emergence rate, but also directly relates to the ability to grow well. Miao, strong seedlings. Therefore, from the sowing to transplanting stage, the need for illumination of flowers should be met as far as possible, and the light intensity is a gradual transition from dark to weak light to natural light.
Sunson is committed to the research and development of high quality and efficient Food And Beverage Enzymes for global customers. Alpha Amylase and glucoamylase are often used in the production from raw materials with high starch content and low starch content to solve the stability of clarifying drinks. Starch in that raw materials is converted to glucose and soluble small carbohydrates under the action of amylase and glucoamylase, avoiding the combination of starch granules and precipitating. In the production of cloudy juice, the natural turbidity of the juice can be maintained by controlling the activity of various pectinase. The addition of pectinase can promote the clarification and filtration of fruit juice, maintain the natural flavor and color of the juice, increase the yield, reduce the cost and save energy.
Benefits:
Reduce the viscosity of fruit juice
Clarify the juice
Improve the yield of juice.

Extended storage or adverse conditions such as higher temperature or higher humidity may lead to a higher dosage requirement.
Enzyme preparations are proteins, which may induce sensitization and cause allergic type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
