1. Temperature: the cold resistance of green vegetables is very strong, and they like low temperature environment. They can grow normally at 10 ℃ ~ 20 ℃. Vegetable seeds can germinate and grow at 5 ℃ at least. If they are placed at 20 ℃ ~ 25 ℃, they can germinate in three or two days.
2. Water content: from seed germination to flowering and bearing, vegetables need a lot of water at all stages. Its leaves are big and thick, and the water is easy to be evaporated, so we should keep the soil moist, and do not let the soil dry.
3. Soil: its root system is very developed, with many fine roots, so the deeper soil is its favorite. The best soil is weak acid or neutral soil, and to loose ventilation, these can make vegetables grow better.
4. Flowerpot: it is better to use a tile pot with a height of more than 20cm for planting vegetables, which can make the roots of vegetables grow better, and the tile pot with good aeration and water permeability can also make them grow better.
1. Sowing: green vegetable seeds need to be dried in the sun for three to four hours before sowing. Then, put in 50 degrees of warm water for half an hour, then move to 25 degrees of cold water for three hours, and finally wait until the bud in the environment of 20 degrees can be seeded.
2. Spend the summer: it is a plant that likes low temperature, so when the temperature is high in summer, it is easy to cause the quality of green vegetables to be poor. Try to reduce the temperature to below 30 ℃, and keep the soil moisture sufficient.
1. Downy mildew: downy mildew may appear in the whole development process of green vegetables, which will wither the leaves and affect the whole plant. Therefore, it is necessary to spray aluminum triethylphosphonate in time for prevention and control.
2. Sclerotium disease: sclerotium disease will mainly damage the stems of green vegetables, and in serious cases, the infected parts will be rotted. Generally in the flowering period of the disease, to timely spray sclerotin 1 to 2 times, and timely treatment of the disease.
1. Toxic or not: green vegetables are common vegetables on the market. Naturally, they are not poisonous and easy to cultivate.
2. How long to harvest: if the vegetables are planted in autumn, they can be harvested in two months. If it is planted in spring, it will take three to four months to harvest.
