In order to ensure Miaoquan, Miaoqi, and Weiwu, it is advisable to soak seeds and germination before sowing(3 gallon nursery pots bulk). Lettuce is cultivated in autumn in the open field, and seedlings are usually planted in the middle and late August. The seedling period is at the turn of summer and autumn, the weather is hot(7.88inch plastic plant pots), and the suitable temperature for the germination of lettuce seeds is 15-25 degrees, and the germination rate of seeds above 25 degrees is significantly reduced.
Therefore, it is also necessary to soak seeds and germination in a 15-20 degree environment(cell trays). After drying slightly, germination is carried out at a temperature of 15-20 degrees. When 80% of the seeds are germinated, they can be sown. In summer, the temperature of the well water is low, the temperature of the air in the well is large, and the summer lettuce is germinated(9.06inch plastic plant pots), and the masses are used to hanging the germination in the well.(greenhouse 1 gallon plastic nursery pots in bulk)
The specific method is: learn the soaked seeds(square grow pots), put them into the cloth bag after a little drying, hang them into the well, about 0.5 meters from the water surface, take them out every day and wash them with water. In addition to the above germination method, the seed is treated with phytohormone, such as soaking with cytokinin 100 PPM solution for 3 minutes(2 gallon nursery pots bulk), or soaking with gibberellin 1000 PPM solution for 2-4 hours, and then germination, the effect is good.
(greenhouse 1 gallon plastic nursery pots in bulk)Lettuce seeds are generally suitable for sowing seedlings in the middle and late February, and the emergence of seedlings is slow(cheap plastic plant pots bulk), and the excessive fatigue is much lower than that of learning. Under suitable conditions, first soak seeds with 25-30 degrees of warm water for 7-8 hours, then remove them(2.5inch square nursery pots). It can be germinated and emerged after planting for 3-5 days. After 3-4 days, most of the seeds are budding, that is, Can be sown.
When 2-3 true leaves are grown(nursery plant pots), the weak growth of each hole can be removed, leaving the robust plants to continue to grow. After growing 5-6 true leaves, depending on the amount of base fertilizer input and crop growth, moderate topdressing (suitable for nitrogen, phosphorus and potassium compound fertilizer), once every 15 days, can be spread (buried) between the plants(3.5inch square nursery pots), or spray the fertilizer solution, but must avoid contact with the leaves and roots.
The lettuce seeds are too small and too light, and the lettuce has a short growth period(large plastic terracotta pots), which is usually harvested in about 30 to 40 days. The whole plant can be pulled up from the beginning of the larger plant at each harvest. During the vigorous growth period of the leaves(4.5inch square nursery pots), the water requirement is large, and the soil is required to be kept moist. However, the dipping and water accumulation should be stored between the leaves.(greenhouse 1 gallon plastic nursery pots in bulk)
It is necessary to be accompanied by fine sand, and the main problem of spring impotence sowing is the lack of ground temperature(plastic plant pots wholesale suppliers). The method of soaking seeds and germination before sowing in spring is: because the lettuce has low requirements for light, but the roots of lettuce are shallow, the absorption capacity is weak, and the oxygen requirement is required. Higher(1 gallon nursery pots bulk). Therefore, it is better to cultivate the soil with high organic matter content and loose and fertile soil.
(greenhouse 1 gallon plastic nursery pots in bulk)Lettuce is not heat-resistant, the suitable temperature for germination is 15-22 °C(plastic plant trays wholesale), and the growth temperature is 12-20 °C. Generally, the water is poured once in 2-3 days, and the water is poured in the morning and evening at high temperature. Gradually reduce the amount of water before harvest(4.5inch deep square pots). The lettuce should be properly controlled in the early growth period. Therefore, under natural conditions, seed germination is more difficult.
