First, the significance of seed germination seeds through germination can not only lift the dormancy, but also can make the young shoots in the right time out of the ground, out of the ground neatly, and to improve the germination rate of Yang nursery at the same time can also enhance the resistance of the seedling (disease resistance, drought resistance, resistance to heat, resistance to cold), to improve the yield and quality of the seedling. Therefore, germination before sowing has a very important significance in seedling nursery and afforestation work.
When sown in spring, the seeds, if not germinated, will take a longer time to germinate and emerge (e.g. walnut will take 2-3 months, and acacia hard-grain seeds will sometimes take the second year to emerge). At the same time, will certainly lose many seeds, resulting in a lack of seedlings broken seedlings phenomenon, especially in the north, due to late soil, out of the ground seedlings are encountering high temperature and dry period, so that the seedlings suffered burns, but also susceptible to infection diseases, and cause the failure of seedling nursery work.
The use of traditional methods of germination, because it is difficult to control the environmental conditions, resulting in uneven germination, low seedling rate, and easy to burn seeds, rotten seeds, the use of biochemical incubator can greatly improve the germination potential and germination rate.
Second, select the capacity of the equipment and temperature control accuracy currently on the market germination equipment has wall insulation type germination room and insulation was set type soft shed, its put seed volume up to thousands of liters or more than 10,000 liters, can be used for large-scale seedling base. There are full computer control of temperature, humidity, light, ventilation of the floor-standing artificial climate chamber for germination, seedling, tissue culture, cycle cultivation, the working volume of 200 to 400L, suitable for laboratory use. There are also 1 ~ 20L desktop small-scale germination machine and less than 1L germination box, for vegetable farmers seedlings and seed business units to detect the germination rate, the unit volume of seed for 0, 1 ~ 0, 2kg / L.
Third, pay attention to the humidity of the germination room due to low humidity seeds are not easy to germinate, high humidity is easy to rot seeds, so high-grade climate box with humidity control device, the relative humidity can be maintained between 50% to 90%, some can reach 95%. Simple germination equipment is no special humidity control device. The artificial climate box and light box with perfect light equipment. Unevenness of the temperature, light, can be used to adjust the disk to solve the problem.
Fourth, strive for temperature uniformity and light moderate temperature uniformity before germination neat. Artificial climate box temperature unevenness of less than 1.5 ℃, light box temperature unevenness of less than 1.2 ℃, medium and large germination room temperature unevenness of less than 2 ℃. As most of the seed germination without light, so the general germination machine are not light equipment, a few have medium and low light equipment, and artificial climate box and light box with 3000 ~ 20000Lx of perfect light equipment. The unevenness of temperature and light can be solved by adjusting the disk.
The artificial climate incubator produced by my company has 7 features
1, large dynamic color LED display: the use of my factory independently developed incubator industry's first domestic, with independent intellectual property rights of the large dynamic color LED display, more humanized design, a variety of functional icon instructions, at a glance, more than one set of data on a screen display.
2, fault self-diagnostic function: with the code directly display the fault, and sound alarm, convenient for users to find faults in time.
3, clock display and timing function: easy to observe the incubation time, can be set 0-9999 minutes of timing time.
4, RS485 interface: can be connected to the data or curve recorder and form a computer network, powerful, easy to upgrade.
5、The studio made of high quality stainless steel with rounded corners design makes cleaning more convenient.
6, eight levels, 24 hours programmable T5 energy-saving, lightweight, high illumination plant growth lamp: copy all-weather, natural plant growth environment, to meet your needs of plant growth environment.
7. According to user requirements, high and low temperature alarm can be set, delayed alarm time can be set flexibly
