Temperature: Winter vegetables like cool weather, and the suitable temperature for its growth is between 15 and 20 degrees. Temperatures that are too high or too low are detrimental to its growth; Watering: It likes moisture and needs to keep the soil moist for a long time. If the weather is hot, it needs to be watered every other day; Fertilization: In addition to the base fertilizer mixed in the soil before sowing, the seedlings will In the future, it will need to be fertilized once a month; light: 4 hours of astigmatism every day is enough.

1. Maintenance method

1. Temperature: Its germination temperature is around 25 degrees, and its growth temperature is around 20 degrees. If the temperature exceeds 30 degrees, it is prone to diseases, and the temperature is below 15 degrees. , its growth rate will slow down.

2. Watering: It is suitable for growing in a relatively humid environment. Because it is not resistant to high temperatures, it needs more watering in hot weather. It is best to water it every other day when the temperature is lower. When the time comes, watering once a week is enough.

3. Fertilization: It consumes a lot of nutrients. Especially during the growth period, top dressing is required every month. Farmyard manure can be used as fertilizer, or compound fertilizer with more comprehensive nutrients can be used. When the seedlings first emerge, top dressing should still be based on nitrogen fertilizer to promote plant growth.

4. Lighting: It is not resistant to exposure to the sun. When it is illuminated, astigmatism should be the main light. The lighting time should be four or five hours a day.

2. Breeding skills

1 , Reproduction: It can be reproduced by sowing. The amount of seeds per acre is about one kilogram. The sowing method is mainly broadcast. If it is hole sowing, just put four to five seeds in each hole. After sowing, cover it with a layer of soil, water it once and water it thoroughly, and wait for one to two weeks. The seedlings can emerge in a week, and when the seedlings have three leaves, they can be transplanted and planted.

2. Planting: The density of planting should be determined according to the harvesting requirements. The harvesting requirements are different, and the planting density will also be different. If the purpose of harvesting seedlings is to harvest seedlings, they can be planted in an appropriate density. , generally 15 cm square is best. If the young shoots are harvested multiple times, 25 cm square is enough.

3. Problem diagnosis

1 Insect pests: The main pests of winter vegetables are cutworms and Spodoptera litura. If the plants are found to be infected with pests, poisonous baits can be used to trap them. If chemical agents are used to eliminate pests, they must wait one week to ten days before picking, because The chemicals are toxic, so you have to wait until the medicinal properties have evaporated before you can pick them.

2. Lesions: Its main diseases are anthrax and root rot. Anthracnose needs to be controlled with chlorothalonil, and root rot needs to be controlled with carbendazim.

IV. Other issues

1 , Edible: It is edible.

2. Is it suitable for home cultivation: It does not have high requirements for maintenance environment, and the plant is not large, so indoor cultivation is possible.
