In addition to the above two formulations in production(gallon plant pot), in order to prevent injury to the seedlings, a small amount of water should be sprayed after pouring the nutrient solution. The general illumination time is best around 15 hours. The nursery facilities and equipment are mainly used, such as precision seeding system, plug tray, substrate, nursery greenhouse(15 gallon nursery pots wholesale), germination chamber, seedling bed frame and fertilizer water supply system, and leveling.(bulk buy black cheap nursery pots)
Plug seedling technology can greatly promote the development of tomato seedling industry(plug trays). When the temperature is suitable, select the excellent seed with high emergence rate, disease resistance, stress resistance and high yield, which is suitable for the varieties cultivated in the northern region. Tomato tray seedlings are generally selected from 50-hole and 72-hole format trays(72 cell propagation trays wholesale). The specific process is: soak the trays with formalin 100 times solution for about 15 minutes, then rinse with water. use.
The used tray can also be disinfected and reused with 50% carbendazim WP to increase the utilization rate of the tray and reduce the production cost(cell trays). Tomatoes are sensitive to light, and the light required for normal growth is 30,000~35000lx. If the light is strong, it needs to be shaded to avoid burning the seedlings; if the light is insufficient, the seedlings will be weaker(flat plastic tray). If the light time is less than 4 hours, the seedlings are basically in a state of stopping growth.
(bulk buy black cheap nursery pots)If the illumination time is insufficient, the illumination time can be extended by hanging the reflective screen or installing a fill light(gallon nursery pots). Excellent tomato seeds with a germination rate of more than 95% are selected, and the tomato seeds are subjected to seed soaking treatment before sowing(plastic grow pots). The process is to soak the seeds in water at 50 ° C ~ 55 ° C for 20 minutes, stir constantly during the soaking process, grasp the time and temperature, so as not to burn the seeds.
The precision seeding system is based on the precision seeder(black plastic plant pots). Leaf thickening, can also be soaked with a concentration of 1% potassium permanganate solution, dried in a non-polluting environment, and then placed in the environment of 28 ° C ~ 30 ° C germination. Generally, the seeds are white after about 3 days, and when about 70% of the seeds are white, they can be sown(greenhouse supplies pots). It can be done by machine on demand or by artificial seeding.(bulk buy black cheap nursery pots)
After selecting the trays, disinfection should be carried out(square nursery pots). Therefore, temperature is one of the important factors affecting tomato seedlings. When conditions permit, the daytime temperature is maintained at 25 ° C ~ 30 ° C, the night temperature is controlled at 18 ° C ~ 20 ° C, the humidity can be maintained at about 90%(wholesale greenhouse pots). Generally, after 3 to 5 days, about 70% of the seeds in the seedling tray are unearthed, and they can enter the greenhouse for seedling.

At this time, the temperature should be appropriately lowered, 20 ° C ~ 25 ° C during the day, 15 ° C ~ 18 ° C during the night, if the temperature is too high, it is easy to cause the seedlings to grow(seed starter trays). Watering after sowing, and then covering a layer of vermiculite, the thickness is about 0.5 cm, the thick soil is not conducive to seed unearthed.
