1. The most suitable medium for the growth of flower seedlings is 20-25% free pores and 50% water retention. General loam, free porosity 1.8, fine sand 2.5, perlite 29.8, vermiculite 27.5, peat/vermiculite (1:1) 24.3, peat/vermiculite/perlite (1:1:1) 27.8, sand/peat (1:1) 9.4, loam/peat (1:1) 6.3. Everyone knows that peat is expensive, but the amount of seed used in seed production is very small. It should be to invest in less medium and get better results. Northeast peat generally has a pH of about 4.0. Due to the low pH value of Canadian peat, the bacteria are not easy to grow and thus achieve a pathogen-free effect.
2. Air flow is an important aspect in the cultivation of flower seedlings and finished flower production in greenhouses. Air flow benefits include (1) dehumidification (2) loam surface,
Dry leaves surface, fungal spores are not easy to germinate (3) make the plant swing to dwarf effect (4) increase the exchange of CO2 and O2.
3, to provide a suitable germination environment, the best way is to build a germination room that can control the temperature and humidity.
4, to prevent uneven sowing, to prevent the spread of the disease and make the soil can be uniform drying / moisture, the best way is to sow in a hole in the tray, and placed in the tray thick fiber peat mixed media, so you can Make sure that the seeds are sown evenly, that the soil is very dry/wet and that the disease can be prevented from spreading. Seeding in a tray is a time consuming job and growers can consider using a simple planter to mechanize sowing.
5. When the small seedlings are watered, fine spray nozzles are used. Under the normal water pressure, they are dew-shaped to achieve the functions of watering and heat dissipation.
6. The seeds with large particles should be covered with vermiculite and perlite. Due to heavy objects, the roots grow downward.
7, rodents like to eat a bunch of red seeds of large seeds, rodents is also one of the necessary work.
At present, the domestic producers of flower and pot flowers have gradually abandoned the conventional varieties produced in China and purchased hybrid flower varieties abroad. Hybrid flowers have many advantages, such as strong growth, strong disease resistance, many flowers, large flowers, fast and neat germination.
In Europe and America, each grower used to raise their own seedlings and then transplant them. If the seedlings are smaller, they will wait for a while. Under this kind of production structure, the performance of flowers is less important. However, now flower production (especially seedlings) has become an industry, seedling professional companies can produce hundreds of millions or more of flower seedlings each year, and relatively require “completelyâ€, “fast†and “neat†seed germination. In other words, it is required that the "all" flower species should be "neatly" sprouted in the "shortest period of time." The flower seed company also understands these requirements. After many years of selection and breeding, it has introduced a number of advantages of conventional hybrids. Its characteristics are the environment that these flower seeds need, such as light, temperature, humidity, and pH. Water, nutrients, etc. These seeds can show their genetically superior traits:
"Full," "quick," and "neat" germination. These flower species are very strict to the environment. If these requirements cannot be met, their performance may sometimes be worse than the old-fashioned ones. It is hoped that the growers who are engaged in grass flower and potted flower production must pay attention.
Sweetener is a food additive that provides a sweet taste like that of sugar while containing significantly less food energy. Some sugar substitutes are natural and some are synthetic. It allows you to enjoy sweet tasting foods without the extra kilojoules from sugar. It can be beneficial for anyone trying to lose weight and control their sugar intake. Sweetener also does not contribute to tooth decay, as they are not broken down to acid by bacteria in dental plaque.
