Details of the seeding of red maple seeds in the united states
Life can last from 6 to 12 months, depending on, inter alia, the level of drying of seeds, storage temperature, storage humidity, etc. The level of seed drying is related to the origin of the seed, the timing of the harvest, the maturity of the seed, the import batch, etc., and is beyond control. However, the temperature of storage of red maple seeds in the united states is critical, and the company's suppliers in the united states require storage at 0°c to 5°c, ideally 3. 3°c. At the same time, appropriate humidity is maintained, usually through the storage of plastic bags with air vents for seed breathing and some humidity. Because of the uncertainty of the season during which many customers purchase seeds, and the lack of suitable storage conditions and knowledge to store them for months or more, the early death of seeds as a result of improper storage is likely to lead to the failure of spring breeding. It would be preferable to order the baby in advance and pick it up one month before the birth and immediately upon receipt。
Seed sprouts
Dry red maple seeds in the united states have hibernation properties, most of which are deep and, in small cases, shallow hibernation. If seeding occurs immediately upon purchase, it must be sprung by low-temperature sand deposits. There are several reasons why seeds fail:
1. High temperature of impregnated water. Seeds should preferably be immersed 12 to 24 hours in warm water of 40 degrees before seed sprouts, diluting the seeds to influence the hormones in which they sprung, and “activating” the seeds. When water is hot, it can cause damage to seeds and reduce their growth rate。
2. No seed impurities were removed. Seeds are caught in the process of harvesting with impurities such as branches, leaves, etc. Owing to the size of the harvest, the collectors and distributors are unable to remove all impurities, which, even at low temperatures, can corrod with wet sand and produce a large number of bacteria, resulting in the failure of breeding。
3. The layer is wet enough. The inability to grasp the humidity of sand during the sandy layering process can also affect seed gerries. Overdry seeds can lose moisture and return to hibernation, and they cannot germinate; they are too wet to breed disease, causing the seeds to rot and leading to nursery failure. It is usually better to use hand-to-hand groups without drops of water, so that the cleavage of sand can break up with moisture。
4. Sealed storage of seeds. In some cases, customers, for reasons of economy, simply mix seeds and wet sand and seal the layers. This is based on the assumption that seeds will be flipped twice a week. This will release carbon dioxide from seed breathing and have enough oxygen. At the same time, the humidity is even and the layer is complete. If stored in a snake-skin bag, the sand and seeds close to the snake-skin bag will normally be dry first, and if the outside is wet enough to mix in and out; if most are dry, water will be sprayed in a timely manner and the original humidity will be maintained。
5. Short or long layers. U. S. Red maple seeds theoretically allow a month-and-a-month cryogenic accumulation, but are usually recommended for one month only. Why? This is due to the fact that the hibernation depth of red maple in the united states is determined by the short, incomplete layers that do not completely break the seeds' hibernation, sow the seeding and gestation or seeding rates are low, and by the prolonged build-up, which increases the difficulty of controlling factors such as temperature, dampness, air permeability, etc. During the period, as well as the failure to sow seed. So, it's suggested to build up for a month. In early spring, in february, experienced growers in the east china region built up with wet sand piles at room temperature。
6. Layer temperature. It is recommended that low-temperature sand deposits be made in the freezer's cortex or in the cupboard, with temperatures ranging from 0°c to 5°c, with 3°c being ideal. The right temperature allows the seeds to accumulate completely, break hibernation and prevent the growth of harmful bacteria. However, the planter's refrigerators cannot be fine-tuned in temperature control, either up to 7°c to 8°c or higher, resulting in the growth of a fraction of the seed layer, but the seeding has not yielded much。
Seed seeding
Appropriate seasonal sowing. Upon completion of the processing of red maple seed layers in the united states, it is recommended that seeding be done in a timely manner at suitable outdoor temperatures. Usually, the most suitable season in east china is february-march, with temperatures ranging from 15°c to 20°c during the day, which is the ideal season for planting. First, the bed is made up, water is poured and seeded, and density is regulated by its own circumstances. It is only 0. 5 cm to 1 cm thick. And a sealed plastic membrane arch should stay warm and humid. The two key factors here are the thickness of the soil and the shacks。
2. Land thickness. The thickness of the lid is critical, as it keeps the soil warm and humid, so that the seeds take root and the seeds sprout and excrete their shells. The soil is too thick, the seeds can't break and suffocate. The earth floor will see the seed sprouts, and it won't come out. The soil is too thin, the seeds are not deep-rooted, they are prone to fall and their shells are capped。
Absorption of lacquer. After seeding of red maple seeds in the united states, seed beds will soon be destroyed because the dust is between 0. 5 cm and 1 cm, if the tectonic membranes are not buttoned. Untimely recharge can result in a loss of seedlings; even if the recharge is timely, if at higher temperatures, it can quickly disperse, forming a sheeting of seedbeds, which is also detrimental to seedlings. However, if seeding is not done in the right season, especially during the high-temperature season, it cannot be removed. Overcrowding in the shed is also due to external temperatures of more than 30 degrees and the retrenchment of the shantytown. Some clients sow directly in the open due to the high level of sowing and, if the season is right, they do so in good times, such as before the dawn, which is just in time for the rainy season, and when the conditions for sowing are right and the soil is right, so the seeding is better. He continued to sow the following year, with a high-temperature weather, which was not so thick as to be able to refill the water in time. It is therefore recommended that nursery planning be done well in advance and that seeds be procured to maximize scientific rational planting of seedlings during the appropriate season to reduce unnecessary losses。
Other aspects
With regard to the seeding of red maple seeds in the united states, there are actually too many lessons to be learned. Because of the lack of uniform standards in the process of breeding red maple seeds in the united states and the many randomities and uncertainties, and because any small detail factor will determine the success or failure of seedlings in the united states, the results of seedlings purchased by different companies will vary widely, even in batching of the same batch of red maple seeds purchased by the same company。
There are also significant differences in the fertility of different growers, as the ability of different growers to control seed processing affects the outcome. There will also be significant differences between the different batches of american red maple seeds handled by the same grower. According to promising feedback from guangxi guierin growers, seedlings are better when they are soaked with root powdered red maple seeds in the united states. While there is no argument for this, we believe that there should be a lot of lessons to be learned from the seeding of red maple seeds in the united states。
In addition, many growers who buy american red maple seeds consult us about varieties. In the united states, red maple is broken down into a dozen well-known varieties, such as sunset red, october glory, autumn flame, fort house and green. However, information from the university of florida in the united states indicates that the varieties of red maple in the united states are specified according to different tree shapes. There is no scientific basis for the good colour of the sapling leaves in many planters。
The most common example is that we know how to watch red leaves in the autumn, not in the city. Why? Because the climate is different. So, the leaves of american mammoth are not red, mainly by climate. It is undeniable, of course, that there are differences in seedlings between sources, families, etc., and that there are significant variations, but this is the way to screen new varieties of red maple in the united states. If there was no variation, there would be no american red maple species. We suggest that growers be careful when we see a lot of people buying american red maple seedlings at high prices. Usually, the southern united states also cultivates and sells to the northern part of the united states the seed seedlings of american mammoth seed from the northern united states。
