Temperature: The cold resistance is not high. The normal growth temperature is between 21℃~27℃. Watering: There should be enough water during the growing period, but be careful not to water too much through the winter. Light: It needs to receive full sunlight during the entire growth process. Only normal and sufficient light can meet its growth needs. Fertilization: It can grow robustly in fertile and loose soil.

1. Maintenance methods

1. Maintenance method

1. Temperature: Its cold resistance is very high, so the general ambient temperature needs to be kept between 21 degrees and 27 degrees, and the temperature in winter is also It needs to be kept at least above 7 degrees to prevent frostbite. The temperature in summer should not be too high to reduce the occurrence of plant ulcers.

2. Watering: A lot of water is required during the growth period , because only in this way can the plant grow more ideally, and at the same time the meat will be thicker and have more juice. Especially in the summer, you need to pay more attention to this. You need to water it almost every morning and evening. In winter, there is no need to water frequently. Moderate watering can allow it to survive the winter normally.

3. Light: General light can withstand it. Within the range, there is no need to worry about the risk of sunburn. Of course, try to provide it with sufficient warm sunshine, so that it will grow more vigorously and the color will be more perfect.

Fertilization: It needs to absorb some trace amounts during its growth Elements, and this is also necessary for its growth, so you need to apply some compound fertilizer to it during the growth period, but be careful to apply thin fertilizer frequently, and do not apply too much each time, otherwise the plant will be burned to death.

2. Breeding skills

1 Propagation: Sowing and bulb propagation are the main methods. Sowing is done in spring. After sowing, pay attention to temperature and watering, and wait until it grows three leaves before transplanting. For bulb propagation, bury the head of the onion directly into the soil, then control the watering and wait for it to germinate. Of course, among these two methods, sowing can be planted in a large area, and bulbs are generally used in family farming.

3. Problem diagnosis and treatment

1 . Disease: Purple spot disease will occur during the fruit maturity period. This disease will seriously affect the yield, so you need to choose disease-free seeds when planting, and you also need to reduce the humidity to prevent it.

2. Pests: Aphids may occur, dichlorvos can be used Solution to spray.

4. Other questions

1 , Toxicity: Not toxic, edible, very suitable for breeding.

2. Can it be raised at home: Yes, at home Breeding can only be done in small quantities, and large-scale planting still needs to be done outdoors.
