Tomatoes are planted in greenhouses, and varieties that are resistant to low temperature(gallon pot), low light tolerance, strong disease resistance, early maturity, high yield, high quality, good commodity, and adapt to the market are selected. Seeds should be sterilized before sowing to prevent seed contamination(50 cell seed starting trays). The seeds can be immersed in hot water at 50 ° C ~ 55 ° C for 15 minutes or in a 50% carbendazim 500 times solution for 20 minutes.(plastic 104 cell seedling trays wholesale)
After sowing, the daytime temperature is controlled at 25-28 °C, at night it is not lower than 20 °C, and it can be emerged in 3 to 4 days(plastic plant pots wholesale suppliers). Before the seedlings are unearthed until the first true leaves are emitted(72 cell seedling trays wholesale), the temperature should be appropriately lowered to maintain a large temperature difference between day and night at 23 to 25 ° C during the day and 13 to 15 ° C during the night to prevent the seedlings from growing.
Generally, after the seedlings are slowed down(large plastic terracotta pots), the bed temperature should be gradually reduced, and the temperature difference between day and night should be increased to facilitate the cultivation of strong seedlings. To adapt to the environment of plastic greenhouses with low temperature and large temperature difference in early spring(105 cell seedling trays wholesale). The tomato in the greenhouse has a long growth period, and the base fertilizer should be applied.(plastic 104 cell seedling trays wholesale)
The organic fertilizer is 3,000 kg per mu, and the compound fertilizer is 60-80 kg(cell trays). The long seedlings can be rejuvenated by shallow cultivating or staging soil. After 3 to 5 days after planting, the seedling water is poured. Before the first spike of tomato is stable, it is mainly based on vegetative growth, and the water is planted with water and the seedling water is no longer watered(128 cell seedling trays wholesale). There are three types of tomato pruning methods: single dry, double dry, and main and dry.
(plastic 104 cell seedling trays wholesale)The plant can be made into a 1.2-meter flat ridge, and the ridge plant can be made into a 60-centi wide ridge(nursery plant pots). Each time the seedbed is broadcasted, the chlorothalonil 500 times solution is used for bed soil disinfection. For seeding, seedling trays can be used to load nutrient soil, or seedbeds can be used for live broadcast(15 cell trays bulk). Then rinse with clean water, then let people immerse for 3 to 4 hours in natural water temperature, remove the dry and dry to be broadcast.
When the first ear is stabilized, the potassium sulfate compound fertilizer is applied per acre combined with watering(plastic plant trays wholesale). 20 to 30 kg, the second panicle and the three panicles should be chased 3 times in the rapid expansion period, and 20 to 25 kg of potassium sulfate compound fertilizer should be applied(128 cell plastic propagation tray wholesale price). From September to October, each yellow board will kill about 90 leaves per month, which can greatly reduce the amount of insects.
The yield is high, and when the fruit begins to expand, it can not only strengthen the disease, but also promote fruit development and improve quality(cheap plastic plant pots bulk). For the cultivation of protected land, a single dry pruning is generally used, and the side branches and side buds are removed when pruning(162 cell seed starting trays). It is not premature to erect, tying and tying the vines, so as not to cause inconvenience in the management of the pastoral, generally when the first inflorescence of the plant is swollen and the second inflorescence is flowering.(plastic 104 cell seedling trays wholesale)
The spring tomato in the greenhouse can be ridged or made(square grow pots). Timely fruit thinning can improve the light conditions of plants, increase the weight of single fruit, reduce the occurrence of deformed fruit, fruit size and other irregularities, and improve fruit yield and commerciality. Generally, 3 to 5 fruits are left per ear, and the large fruit that is strong, round, and sunny is generally left at 3 to 4 layers(200 cell seed starting trays). Highly toxic pesticides are strictly prohibited, and the number of spraying is strictly controlled.
