1. Temperature: the place where the lettuce likes to grow warm, is not resistant to low temperature. The plant will grow normally only when the maintenance environment temperature is more than 15 ℃, and will not tolerate high temperature. The plant will stop growing when the maintenance temperature is more than 30 ℃, so the temperature should be kept between 15 ℃ and 30 ℃ during the maintenance process.
2. Watering: it likes the humid living environment. If the soil is dry for a long time, the plants will not grow well. Its root is not resistant to waterlogging. Every time when it is watered, the soil is completely wet, and there is no water in the soil. It needs to be watered once every two days in dry weather, and it needs to do well in non dry weather.
3. Fertilization: it needs nutrients for its growth. To make the plant grow well, it must be fertilized according to its growth state. If it grows well, it can use organic fertilizer once a month. If its growth state is not good, it needs to use compound fertilizer. Because the compound fertilizer has sufficient nutrients and comprehensive nutrients, it can meet the needs of all aspects of the plant.
4. Light: it is not resistant to strong light. The light mainly comes from astigmatism. The daily light time is guaranteed to be four hours.
1. Reproduction: it can be propagated by sowing method. First, select seeds, remove the dried and moldy seeds, leave the seeds with full grains, and then evenly sprinkle the seeds into the prepared culture medium, cover it with a layer of soil, spray water mist to the culture medium basin with a watering can, and then spray the soil on the surface of the plant.
2. Weeding: the plant is relatively small, easy to mix with weeds, and it is difficult to row weeds. In order to avoid unnecessary nutrient consumption, it is necessary to pull weeds frequently in the management process. It is not possible to wait until the grass is large, press the seedlings down and then pull weeds. For weeds, early detection and early treatment are needed.
1. Insect pest: its main pest is aphid. After infecting aphid, its leaves will turn green and black, so it can't eat. Moreover, the disease plant will also infect bacteria. If aphid is found, 40% dimethoate 1500 solution should be used to spray the disease plant..
2. Disease: its main disease is downy mildew virus, which usually occurs in summer and autumn. At this time, the air is humid and easy to breed bacteria. At the beginning of the disease, chlorothalonil can be used to spray easily.
1. Edible: edible.
2. Whether indoor seeds can be planted: it can be planted indoors, because the plant body is smaller, and the requirements for maintaining the environment are not high, so it is OK to breed at home.
