What Are The Reasons For The Low Rate of Seed Germination?
1. Seed soaking time of different seeds is different in different time, with short soaking time, insufficient water absorption and low germination rate;
2. The water absorption and germination rate of seeds are closely related to the temperature environment. If the temperature of soaking seeds and accelerating germination is too high or too low, it will make the seeds unable to absorb water and the germination temperature unsatisfactory, resulting in a low germination rate.
Here is how to effectively improve the success rate of seed germination:
Ⅰ.Sunning The Seed And Choosing Good Seed
Prior to seed hastening, seeds should be dried and selected in advance. Sun planting has the following advantages: improving the water absorbing ability of seeds, killing some pathogenic bacteria on the outer shell of seeds, making the seed germination rate high and the seedling orderly, making the seedling grow strong and the disease is less.
1. Seed drying: the seeds should be spread evenly on a sunny day 2 to 3 days before accelerating the germination. The seeds should be spread thin when planting, and the seeds should be turned over frequently in the process to make the seeds more even.
2. Seed selection: full and full seeds will have a better germination rate and seedling situation. Therefore, it is necessary to conduct seed selection before accelerating germination.
Many seeds are smaller (vegetable seeds, for example) and are difficult to pick. Seeds can be selected with water or salt water: seeds of common varieties can be screened with salt water, and mixed seeds are best screened with water. Empty granules can be removed with clean water, and empty granules can be eliminated with salt water.
A lot of people have such a problem that we use clear water to select a species, but the concentration of salt water to select a species is not easy to grasp, how to do? Tell you a relatively simple method: when the salt water is ready, you can put an egg into it. If the eggs are all submerged under salt water, it indicates that the concentration of salt water is too low and salt needs to be added. When an egg shows only a coin's worth of salt water, the concentration of salt water is appropriate. This method is very simple. Have you learned it?
Ⅱ.Infested The Seed
In order to improve the quality of sowing, it is better to disinfect seeds before sowing, which can significantly improve the rate of germination and greatly reduce the occurrence of diseases and pests in a later stage. So how do we do that?
Scorched by kinds of seed, seed selection, wash, in 50 to 55 degrees warm water soak 10 to 15 minutes, remove the fish in clean water and soak for 2-3 days (seed different soaking time, such as tomato seed soaking for 24 hours, the balsam pear, towel gourd seed soaking 48 hours), every 4-5 hours in a clear water, when the seed soaking water quantity for around 50% of seed weight, seed has been absorbing water saturation, at this time to sprouting at this moment, the highest germination rate. In the process of seed soaking, if the seeds are sterilized with 1, 000 times of polymyxin, it can better reduce the occurrence of seedling diseases after sowing.Ⅲ . Sprouting Operation
If you have the condition, it is better to use the terminator, which is convenient for constant temperature and humidity, so as to better control the temperature and humidity of the germinator.
Method:
Insulation: a 60W LED grow lights suspended in a small hole on the top of the foam box. The bulb is 20 cm away from the seed and used only when the temperature is low.
Moisturizing: put a clean and wet cloth on the bottom of the box, put in seeds, and cover with a wet cloth;
Plug in the thermometer from the top of the box and check the temperature at any time.
Specific operation: For soaking seeds out of ventilation to dry, then use clean gauze wrapped seeds such as (parcel is the seeds cannot too tight, should leave some space for seed germination), on heat preservation box or indoor environment sprouting (can fit into a thermometer all the time, in order to grasp the sprouting temperature at any time, check temperature once every 5 hours), constant temperature environment seeds in 30 to 32 generally in about 12 hours can break the chest, and then control the accelerating seed germination temperature to 25 to 28 degrees continue sprouting, under the condition of constant temperature, average 24 hours to rush budding strong kind of bud, bud of the standards, The germination rate is generally above 90%, when 60-70% of the seed germination can be used to sow seeds.
Of course, for some friends who like to plant flowers, you can simply use a paper towel for budding. The operation is as follows: find a sealed pot, wet the paper towel and spread it on the bottom of the irrigation, then spread the flower seeds evenly on the paper towel, cover the cover and put it in the warm shade, usually after a few days, the flower seed can germinate. Or place washed flowers on a wet towel and cover them with a clear glass cover. For those seeds with thick and hard shells, they should be soaked before budding.
Seasonal Problems
Growers use greenhouses to produce their crops in the first place to provide insulation and protection for plants grown in the greenhouses, but this artificial environment also has many problems. For example, for plants growing in a greenhouse, especially young plants, relatively short periods of high temperature or sun exposure can cause serious damage to the plants, so it is very necessary to take corresponding preventive measures. Ventilation and sunshade are the two main cooling methods in the greenhouse to ensure the normal growth of plants. When choosing a greenhouse that is suitable for growing plants, you should first consider whether the greenhouse is equipped with a fan. When the temperature inside the greenhouse increases, the fan can be used to adjust, so as to reduce the temperature inside the greenhouse.
Some plants have high light resistance and are relatively resistant to sun exposure, but many require a degree of shade to protect them from direct sunlight. There are many ways to protect the seedling from the sun. When the sun is strong in the afternoon, it can be shaded on the top or side of the greenhouse to avoid direct sunlight, and reduce the possibility of heat damage.
Low-Temperature Disaster
If suddenly encountered cooling, frost in the greenhouse will cause frost damage to the plants. Because of the complicated and changeable weather conditions, the occurrence of catastrophic weather cannot be predicted accurately and timely by relying on the weather forecast alone. The greenhouse needs to arrange the warm air blower or the warm air machine, the best can control automatically, when the frost occurs, the greenhouse internal greenhouse reduces, the warm air fan can carry on the warm air automatically, thus guarantees the greenhouse the plant to grow normally the need, but is not affected by the outside weather change. If cost and benefits are taken into account, you can also choose the most popular LED grow lights on the market.

It is a big problem that the humidity in the greenhouse is easy to produce condensation water. Humid, unventilated air environments provide ideal conditions for many germs, especially grey mold. Therefore, maintaining good air mobility is one of the key measures to reduce the occurrence of diseases. One of the reasons why the condensation water in the greenhouse is easily neglected is that in winter, in order to improve the internal temperature of the greenhouse, a heater is used, and the fuel will produce a large amount of water in the combustion process. In winter, the outdoor temperature is low, the ventilation in the greenhouse is not very good, and the air circulation is not good.
Greenhouse Space Planning
Overly burdensome management inevitably leads to problems or loss of interest. While you'll start out with a management plan, there are always problems that can overwhelm an inexperienced grower. Growers are often unaware of the large areas of greenhouses they choose to plant, resulting in too small an area. So when choosing a greenhouse, make sure you have enough space for future expansion. If you want to expand the production area, but cannot really expand the existing greenhouse space, then you can only choose the second greenhouse to supplement.
It is difficult to leave enough space in a greenhouse to store equipment and keep it clean, especially in a relatively small one. All the objects in the greenhouse should be well known and know how to properly plan the use of space. Use a waterproof case to prevent rust or damage. Chemicals such as pesticides need to be stored safely to prevent accidental damage to children or pets. Due to the lack of sufficient space, and the cleaning work in the greenhouse itself is not easy to do well, so the equipment and goods are put in order, which can also reduce the risk of diseases and pests in the greenhouse.
Prevention And Preparation In Advance
The problems of gardening in open fields inevitably occur in greenhouses as well. Only by understanding the problems that may occur in advance can we prevent them from happening in the future, reduce the potential risks and solve the problems that have occurred in a timely manner.
Daily Maintenance of The Greenhouse
A greenhouse is like a house we live in. It needs regular maintenance to keep it tidy. Generally speaking, it is to maintain the inside and outside of the greenhouse, including the structure of the greenhouse, heating equipment, ventilation equipment, water supply system, and the most important environmental maintenance of the greenhouse itself.
1. Routine Maintenance
The greenhouse needs to be constantly checked for damage. Glass greenhouses should be checked for integrity after strong winds. The greenhouse's skeleton structure also needs regular inspection. Bamboo and wood structure greenhouse needs to be painted regularly or anticorrosive treatment, repair damage at any time. Aluminum frame greenhouses, on the other hand, require no such work and are relatively cheap to maintain.
2. Clean
Cleaning the greenhouse on a regular basis can protect the greenhouse's skeleton structure. If the mulch of the greenhouse is not clean, it will reduce the intensity of light and affect the seedling growth. You can choose to do the overall cleaning before planting in spring or before planting in autumn.
External cleaning of the greenhouse is optional on a windy day. Clean the mulch with water. The water on the mulch will evaporate quickly in a windy environment to avoid watermarks. For the aluminum greenhouse, the dust can be collected easily under the window, which can be washed directly with a water pipe, and the dust can be removed gently with the setting tool.
The inside of the greenhouse needs more thorough cleaning, not only for the sake of a pleasant and clean working environment but also for the prevention and control of various pests and diseases in the greenhouse. Greenhouse cleaning is a very important part of greenhouse management, which effectively avoids many possible troubles.
When cleaning the greenhouse, make sure the power is off, turn off the heater, LED plant lights and other related equipment, and cover the socket. If outdoor temperatures are allowed, it is best to move plants, containers, and equipment outdoors, or keep plants in other greenhouses to prevent them from freezing. Take the time to examine each plant and remove the stumbles.
Used fertilizer and planting bags can be discarded, the ground leaves to clean up, weed. A comprehensive cleaning and disinfection of the greenhouse, including glass, walkways, and walls. Leave all the plants to dry and put them back in the greenhouse.
3. Equipment Inspection
Heaters, ventilators, and irrigation systems are very important and don't forget to check and maintain them regularly. There are also containers such as flower POTS and workshops that also need to be sterilized. The lighting system also needs a regular inspection to check if it is normal, and the lamp that cannot be used should be replaced in time.
4. Maintain The Planting Environment
In the warm and humid greenhouse environment, diseases and pests are very likely to occur and spread rapidly when given the opportunity. Therefore, it is very important to keep the environment in the greenhouse clean and tidy. Make necessary supports to the plants, trim off the points, etc., and weed the land in time.
Greenhouse cleaning is just as important as cleaning your house, but regular maintenance is just as important, making everything in the greenhouse work normally. If you can maintain regular maintenance, it will take less time each time.
Prepare
Winter is a very special time, because of the lack of light, cold weather and so on makes the growth of plants very difficult. At this time, we must pay close attention to the possibility of various problems, try to keep clean and tidy to reduce the possibility of various problems. Use tools to get plants through the winter.
